Nature of the Contract of Sale

How to use this guide

The eleven articles in this assignment answer one question: what is a sale, and what is it not? Everything else in the subject — delivery, warranties, remedies, the Recto and Maceda Laws, the whole of Lease — presupposes that you can tell a sale from the things that resemble it.

The guide is built article by article. Each article opens with its text set out in full, then unpacks the rule in plain language, then brings in De Leon, then works through the assigned cases at the point where they actually bite. The cases are not collected at the end. A case earns its place by resolving the article's hard question, and that is where you will find it.

Three things are flagged throughout:

• Trap — a distinction that looks obvious and is not. These are where cold calls go wrong.
• Exam angle — how the point would be framed in an IRAC or ALAC answer.
• Ahead — a doctrine that belongs to a later article but that you cannot avoid touching now.

A cold-call cheat sheet and a bank of anticipated Socratic questions with model answers sit at the end.

A note on scope

The assignment stops at Art. 1468. De Leon's Chapter 1 runs to Art. 1488, and three provisions just beyond the cut keep intruding because the assigned cases turn on them: Art. 1475 (perfection), Art. 1477 (ownership transfers on delivery) and Art. 1478 (parties may stipulate that ownership shall not pass until full payment). They are quoted where needed and marked ahead of the syllabus. You are not expected to master them yet, but you cannot explain Toyota Shaw or Dignos without them.

The sixteen cases, mapped

Three cases pull double duty. Gaite is the anchor for the commutative character of sale under Art. 1458 and the leading authority on the sale of an undivided mass under Art. 1464. Akang settles both the classification question under Art. 1458 and the determinateness question under Art. 1460. De Guzman is a contract-to-sell case in the majority and an Art. 1459 case in Justice Caguioa's separate opinion.

Where the weight sits. Eleven of the sixteen cases are Art. 1458 cases, and nine of those eleven turn on a single question: is this a contract of sale or a contract to sell? That is the centre of gravity of the whole assignment. If you prepare one thing thoroughly, prepare that.

Part I — Orientation

Where these articles sit

Title VI of Book IV of the Civil Code is "Sales". It opens with Chapter 1, "Nature and Form of the Contract", which runs from Art. 1458 to Art. 1488. Your assignment covers the first eleven articles of that chapter, and they divide into three unequal groups.

Article 1458 stands alone. It defines the contract, states its two great obligations and announces that a sale may be absolute or conditional. Everything after it is either a gloss on one of its elements or a boundary marker separating sale from a neighbouring contract.

Articles 1459 to 1465 are about the object. Art. 1458 says the seller must transfer ownership of a determinate thing. These seven articles unpack what that thing must be: licit and transferable (1459), determinate (1460), possibly future (1461, 1462), possibly undivided (1463, 1464), possibly defeasible (1465).

Articles 1466 to 1468 are boundary markers. Each answers "is this a sale or is it something else?" — agency to sell (1466), piece of work (1467), barter (1468). De Leon adds two more comparisons the Code does not: lease and dación en pago.

A useful image: Art. 1458 draws the outline of the contract; 1459 to 1465 fill in what may lawfully sit inside it; 1466 to 1468 patrol the fence.

Why the boundary matters commercially

The classification questions are not academic pedantry. Look at what turned on them in the assigned cases. In Quiroga a dealer's whole defence — that he was an agent and therefore owed no price for unsold beds — collapsed the moment the Court held the contract a sale. In Arnoldus and Concrete Aggregates the label decided whether a business paid 3% contractor's tax or 7% manufacturer's tax, and in Arnoldus whether it kept an export-sales exemption worth more than a hundred thousand pesos. In Dignos the label decided who owned a beach resort.

Part II — Article 1458: the definition

1. The two obligations, and the one that is new

Read the first paragraph slowly. The seller undertakes two things — to transfer the ownership and to deliver. The buyer undertakes one: to pay a price certain in money or its equivalent.

The doubling on the seller's side is deliberate and is the single most important change the 1950 Code made to this title. Under the Spanish Civil Code the seller's obligation was merely to deliver, so that a person who did not own a thing could validly sell it, subject only to a warranty that the buyer would not be evicted. The Code Commission thought this "unsatisfactory from the moral point of view" and wrote the obligation to transfer ownership into the definition itself.1

The practical consequence runs through the entire subject. A seller who delivers but cannot convey ownership has not performed. That is why Art. 1459 requires a right to transfer ownership, why Art. 1547 implies a warranty that the seller has a right to sell, and why nemo dat quod non habet — nobody gives what he does not have — is a live principle in Philippine sales law rather than a Latin ornament.

A caution on the phrase "price certain in money or its equivalent." "Its equivalent" does not open the door to barter. It means instruments that stand in for money — a cheque, a promissory note — or a thing that has been assessed and its money value determined.2 Goods as such are not "the equivalent of money"; a contract whose consideration is goods is a barter, and Art. 1468 tells you how to sort the mixed cases.

2. Six characteristics

De Leon lists six, and you should be able to recite them with a one-line justification each. Think of them as six answers to "what sort of animal is this contract?"

1. Consensual — perfected by mere consent, without any further act. Not delivery, not payment, not writing. This is the characteristic that does the most work in litigation and it is the one Far East Bank turns on.
2. Bilateral and reciprocal — both parties are bound, and each party's performance is the cause and the condition of the other's. Delivery and payment are, as the Court put it in Pio Barretto Sons v. Compania Maritima, "so interrelated and intertwined with each other that without delivery of the goods there is no corresponding obligation to pay."
3. Onerous — the thing is conveyed in consideration of the price and the price in consideration of the thing.
4. Commutative — each party regards what he receives as the equivalent of what he gives. Exception: a sale may be aleatory, as in the sale of a hope — a sweepstakes ticket. Hold on to this exception; it reappears at Art. 1461 as emptio spei and it is the hinge of Gaite.
5. Nominate — the Code gives it a name and a set of rules.
6. Principal — it stands on its own and does not depend on another contract for its existence.

3. The three essential requisites

Sale is a contract, so Art. 1318's general requisites apply. De Leon states them in the sale-specific form the cases use:

1. Consent, or meeting of the minds — the seller consenting to transfer and deliver, the buyer to pay. The parties must have capacity (Arts. 1489 to 1491).
2. Object, or determinate subject matter — a determinate thing, or one capable of being made determinate without a further agreement (Art. 1460). It may be personal or real property, and it may be a right, provided the right is transmissible.
3. Cause, or price certain in money or its equivalent.

The absence of any one of them means there is no perfected sale at all. And because sale is consensual, he who alleges a sale must prove it.3

Four of the assigned cases are consent cases. Take them in the order in which the problem arises.

4. Absolute or conditional — and the third thing, the contract to sell

The second paragraph of Art. 1458 says a sale "may be absolute or conditional". Two words, and most of your assigned jurisprudence.

An absolute sale is one subject to no condition, where title passes to the buyer on delivery. A conditional sale contemplates a contingency — most often, on the buyer's side, full payment of the price (Art. 1478, ahead), and on the seller's side the fulfilment of some undertaking such as ejecting squatters before delivery.

But Philippine jurisprudence has developed a third category the Code never names: the contract to sell. Understanding why it exists, and why one Justice of the present Court thinks it should not, is the intellectual centre of this assignment.

The concept in one paragraph

In a contract of sale, ownership passes to the buyer on delivery, and non-payment of the price is a negative resolutory condition: the sale existed, and the seller's remedy is to enforce it or to have it rescinded under Arts. 1191 and 1592. In a contract to sell, the seller expressly reserves ownership despite delivery and binds himself to sell exclusively to the prospective buyer upon full payment; full payment is a positive suspensive condition, and its non-fulfilment is not a breach at all but merely an event that prevents the seller's obligation to convey title from acquiring binding force.

The consequences diverge sharply:

That last row is the one students forget and professors ask about. In a contract to sell, even full payment does not automatically transfer ownership; the prospective seller must still convey by a contract of absolute sale.4

Analogy. Think of a contract of sale as handing over the keys with the deed inside the envelope: the house is yours, and if you fail to pay I must go to court to get it back. A contract to sell is handing over the keys while keeping the deed in my drawer: you may live there, but the house is not yours, and if you stop paying I do not need to undo anything — the transfer simply never happens.

How to tell them apart: the two tell-tale clauses

Dignos supplies the working test, and it is negative. A deed is absolute in nature — whatever it is called — unless the contract contains either:

1. a proviso that title is reserved in the vendor until full payment; or
2. a stipulation giving the vendor the right to unilaterally rescind the moment the vendee fails to pay within a fixed period.

And Tan v. Benolirao supplies the positive counterpart: where the seller promises to execute a deed of absolute sale upon full payment, the contract is a contract to sell, whatever the document is headed.

5. Non-payment, delivery and the passing of ownership

Two propositions must be held together, and students routinely collapse them.

First: ownership passes by delivery, not by payment. Art. 1477 (ahead) provides that ownership is transferred on actual or constructive delivery. Payment is not a condition of that transfer unless the parties stipulate it under Art. 1478.

Second: non-payment of a perfected sale is a resolutory condition, and the seller's remedy is rescission or specific performance under Art. 1191 — not a declaration that no sale ever existed. But the failure to pay in full within a fixed period does not by itself dissolve the sale in the absence of an agreement that time is of the essence.5

The distinction has a hard edge, and Sampaguita Pictures is where you see it.

6. Commutative, not aleatory: condition versus period

The last of the Art. 1458 cases takes the "commutative" characteristic and gives it teeth.

7. Recap of Article 1458

The seller owes two obligations, to transfer ownership and to deliver; the buyer owes one, to pay a price certain in money or its equivalent. The contract is consensual, so it is born at the meeting of minds — no writing, no delivery, no payment required (Far East Bank) — but the minds must meet on everything material, including the manner of payment (Toyota Shaw), by an acceptance that mirrors the offer (Ignacio), on an object that has not materially changed (PHHC). Once perfected, non-payment does not unmake the sale (Akang), and ownership passes on delivery whether or not the price is paid (Sampaguita). Whether the parties made a sale or only a contract to sell turns on two clauses — reservation of title, or a promise to execute a deed of absolute sale on full payment — and not on the document's heading (Dignos, Tan, Pulumbarit, De Guzman). And because sale is commutative, a term for payment is presumed a period, not a condition (Gaite).

We now turn to the object.

Part III — Articles 1459 to 1465: the object

Seven articles, and they divide into pairs. The first two (1459, 1460) state what must be true of the object — it must be licit and determinate. The middle three (1461, 1462, 1463) relax the determinateness requirement for particular classes of things — future goods, goods subject to contingency, and undivided interests. The last two (1464, 1465) deal with special cases — fungible goods sold as an undivided share of a mass, and things subject to resolutory conditions.

Article 1459 — licit object and the right to transfer

Two requirements, one timing rule.

The thing sold must be licit — capable of being the subject of a contract. An illicit thing is void as object (Art. 1409[1]).

• Illicit per se — unlawful by nature (decayed food unfit for consumption)
• Illicit per accidens — lawful in themselves but forbidden by some provision of law (lottery tickets under Art. 195 RPC; land sold to an alien contrary to Art. XII, Sec. 7 of the Constitution)

The seller must have the right to transfer ownership at the time of delivery — not at perfection. This is consistent with Art. 1547(1), which implies a warranty that the seller "has a right to sell the thing at the time when the ownership is to pass". The Code allows sales of future goods and goods whose acquisition depends on a contingency, so requiring ownership at perfection would be absurd. The principle nemo dat quod non habet operates at delivery, not before.

Artates v. Urbi

G.R. No. L-32736, 29 January 1971 · 37 SCRA 395 · Fernando, J.

Facts. On 10 February 1959 the Director of Lands granted Artates a homestead patent over a parcel in Bulacan. The patent was registered in September 1959 and TCT No. 44652 was issued. In October 1960 — thirteen months after issuance of the patent — the Provincial Sheriff levied on the land for a civil liability arising from a crime Artates had committed, sold it at public auction to Antonio Urbi for ₱1,050, and issued a final deed of sale in January 1961. Artates sued to annul the sale on the ground that Section 118 of the Public Land Act prohibits any alienation of homesteads within five years from the issuance of the patent.

Issue. Does the five-year prohibition apply to involuntary sales by public auction?

Held. Yes. Section 118 provides:

"Except in favor of the Government or any of its branches, units, or institutions, the land acquired under this title shall not be alienated, transferred, or conveyed except to one who has resided on and cultivated said land not less than five years, and after such transfer or conveyance, the land so acquired shall not be alienated, transferred, or conveyed for a period of five years from the date of the patent."

The prohibition covers any alienation within the five-year period. "It is immaterial whether the alienation is voluntary, as in an ordinary sale, or involuntary, as in a levy and sale at public auction — in both instances, the spirit of the law would have been violated."

The Court rejected the argument that "debt contracted" means only contractual debts. "Debt contracted" means "obligation incurred", and covers obligations imposed by law without contract. A homestead serves a social policy purpose: it "should remain with the person to whom it was granted and his family... to provide them with a home and means of livelihood". Allowing a levy for a tort or crime "would uproot the homesteader and his family and turn them into homeless waifs as effectively as a levy for non-payment of a contractual debt".

Why it sits here. Artates is an Art. 1459 case because it involves a thing illicit per accidens — the homestead was ordinary land, but Section 118 forbade its alienation for five years. The case is absolute about the coverage of "alienation": voluntary or involuntary, contractual or legal, it makes no difference.

Heirs of Zambales v. Court of Appeals

G.R. No. L-54027, 28 February 1983 · 120 SCRA 897 · Relova, J.

Facts. On 30 April 1963 — within the five-year prohibitory period — homesteaders Isabelo Fernandez and Victoria Mendoza executed a "Deed of Absolute Sale" for ₱5,000 to Eulogio Zambales. The deed provided that ownership would transfer after five years, that the vendors would "continue occupying said land" and that all improvements and harvests belonged to them. The consideration was described as "advance rental", payable monthly at ₱30 for five years, and the vendors executed an irrevocable special power of attorney authorising Zambales to sell the land. After the five years Zambales tried to take possession. The vendors refused and sued to annul.

Issue. Did the agreement violate Section 118 of the Public Land Act?

Held. Yes — it was void. The Court held this was "an executory sale in disguise". Despite its label as a "deed of absolute sale", the contract was reciprocally demandable under Art. 1479 — a bilateral promise to buy and to sell at a price certain. Coupled with the irrevocable agency to sell, it amounted "to all intents and purposes" to an executory sale perfected during the prohibited period. "The law does not distinguish between executory and consummated sales."

The payment scheme and the irrevocable agency "were merely a device to circumvent the prohibition". Labelling the payments "rentals" did not change their nature. The homesteaders had no legal capacity to sell during the five years, so the sale was void from the beginning under Art. 1409(1). Being void, it was entitled to no authority or respect, the action to declare its inexistence did not prescribe (Art. 1410), it could be impeached collaterally, and even executive approval after the five years "would neither legalize the sale".

Why it sits here. Zambales closes the timing loophole. Parties cannot evade Section 118 by deferring the formal deed until after five years if the agreement to sell was perfected during the prohibited period. The Court looks through the form to the substance.

Article 1460 — determinate thing

A thing may be determinate in either of two ways: particularly designated (this lot, bearing title number X) or physically segregated (the pile of lumber on the left side of the yard). What matters is that it can be identified without ambiguity.

The second paragraph relaxes the requirement: the thing need not be determinate at contracting, only determinable without a new or further agreement. If the parties have supplied enough information that the thing can be identified by applying the contract itself, that suffices.

Example — sufficient. Lots described by number and area, plus a statement that they are the ones needed for the city hall site under the Arellano Plan. Determinable — the plan already existed, so no new agreement was needed (Melliza v. City of Iloilo).

Example — insufficient. "600 piculs of sugar of the first and second grade", no particular lot designated. Generic — no perfected sale (Yu Tek & Co. v. Gonzales). De Leon treats such an agreement as merely a contract to sell.

Already covered: Akang v. Municipality of Isulan. The Court held that "two hectares" of a larger parcel was a determinate object; segregation was not required at contracting. That holding appears under Art. 1458 above, where Akang is discussed at length.

Articles 1461 & 1462 — future goods

These two articles deal with future goods — things that do not exist at the time of contracting but may come into existence later.

Two kinds of sale of future goods

Emptio rei speratae — the sale of a thing hoped for. The parties contemplate a specific thing (the harvest, the litter, the catch). If the thing never comes into existence, the contract is ineffective, and no price is owed. This is the general rule and is the presumption in case of doubt.

Emptio spei — the sale of the hope itself. The buyer purchases the aleatory chance, and the price is owed even if the thing never materialises. The classic example is a sweepstakes ticket. The one limit: the sale is void if the hope or expectancy is vain — if at the time of contracting the seller knows or should know the thing can never come into existence.

Example — rei speratae. A sells to B "the harvest from my rice field this season" for ₱50,000. The harvest is destroyed by typhoon. The contract is ineffective; B owes nothing.

Example — spei. A sells to B "whatever I catch in one day's fishing" for ₱5,000. A catches nothing. B still owes ₱5,000 — he bought the chance, not the fish. But if A's boat has a hole and he knows it will sink, the hope is vain and the sale is void.

Art. 1462 adds a third category: goods to be manufactured, raised or acquired by the seller after perfection. A sale of future goods in this sense operates only as an executory contract to sell and deliver at a future time. If the seller later loses the capacity to acquire the goods (e.g., the factory burns down), the buyer's remedy is breach of contract, not restitution — the contract existed and was simply not performed.

Article 1463 — undivided interest

A sole owner may sell a fractional interest — one-half, one-third, etc. — without first partitioning the thing. The effect is to create a co-ownership between the seller and the buyer. The thing remains physically undivided; the buyer becomes a co-owner to the extent of the interest purchased.

Example. A, sole owner of a 100-hectare farm, sells to B "an undivided one-fourth interest" in the land. B becomes a co-owner holding a 25% interest; A retains 75%. Neither has exclusive rights to any part of the land until partition.

This article resolves a question that troubled the Spanish Code: may a sole owner sell less than the whole? Yes. The Code permits it expressly, and the result is governed by the law on co-ownership (Arts. 484–501).

Article 1464 — undivided share of a mass

This article deals with fungible goods sold as a share of a specific mass. Fungible goods are those where any unit is as good as any other — grain, oil, coal.

The rule in two parts

Part 1: Co-ownership in proportion. If A sells to B "250 cavans of rice out of the 1,000 cavans in Warehouse 3", B becomes a co-owner of the entire mass in the proportion 250:1000, or one-fourth. This is so even though A "purports to sell" a definite quantity.

Part 2: Short delivery. If the warehouse actually contains only 800 cavans, B becomes the owner of the whole 800 cavans, and A must supply the remaining 200 cavans "from goods of the same kind and quality".

Contrast: sale of a fraction. If A had sold "one-fourth of the contents of Warehouse 3", B would simply be a one-fourth co-owner. There is no fixed quantity to fall short of, so no obligation to make good a deficiency can arise.

Already covered: Gaite v. Fonacier. The case involved a sale of "24,000 tons of iron ore, more or less" for a lump sum. The Court held this a sale of a specific mass, not a sale of a fixed quantity, so the seller's obligation was to deliver in good faith all the ore in the mass. That holding appears under Art. 1458 above, where Gaite is discussed at length.

Article 1465 — resolutory condition

A sale may validly have as its object a thing whose ownership is subject to a resolutory condition — an event whose occurrence will extinguish an already-existing right.

Example — right of redemption. A sells land to B, reserving the right to repurchase within two years (Art. 1601). B's ownership exists from delivery but is defeasible — if A redeems, B's title is extinguished ab initio. That does not make the sale void; it simply makes B's right conditional.

Distinguish from a suspensive condition. A suspensive condition must happen before the right arises. A resolutory condition, if it happens, destroys a right that already arose. The distinction matters because it determines remedies: non-occurrence of a suspensive condition means the obligation never came into being; occurrence of a resolutory condition triggers restitution and, if agreed, forfeiture.

Part IV — Articles 1466 to 1468: the boundaries

Three articles, three neighbours. In each, the Code tells you how to classify a contract that could plausibly be read either way, and in each the underlying instruction is the same: look at the substance, not the label.

Article 1466 — sale distinguished from agency to sell

By the contract of agency, a person binds himself to render some service or do something in representation or on behalf of another, with that other's consent or authority (Art. 1868). The two contracts look alike from the outside — in both, goods move from a supplier to a middleman who sells them on — and they differ in nearly every legal consequence.

The five distinctions

The single best diagnostic is the second row combined with the third: does the middleman owe the price whether or not he resells? If yes, sale. If he owes only an accounting and may hand the goods back unsold, agency.

Note what does not matter. An agreement that the buyer will deal exclusively in the seller's products is "a well-known practice in the business world" and is not inconsistent with a sale, much less does it convert the contract into agency, where entire control of the business operation remains with the dealer.

Andres Quiroga v. Parsons Hardware Co.

G.R. No. 11491, 23 August 1918 · 38 Phil. 501 · Avanceña, J.

Facts. In 1911 Quiroga, a bed manufacturer, and J. Parsons executed a contract headed "for the exclusive sale of Quiroga beds in the Visayan Islands". Its terms: Quiroga would furnish beds and invoice them at his Manila selling price less a discount of 25% "as commission on the sales"; Parsons was to order by the dozen; Parsons bound himself "to pay Mr. Quiroga for the beds received, within a period of sixty days from the date of their shipment", with a further 2% discount for prompt or cash payment; transport was split; Parsons bound himself not to sell any other kind of bed; and the words "agency" and "exclusive agency" appeared in articles 2 and 3.

Quiroga sued, alleging that Parsons had breached obligations implied in a commercial agency — not to sell above invoice prices, to keep an open establishment in Iloilo, to conduct the agency itself, to keep the beds on public exhibition and to pay for advertising. None of these was written in the contract. Everything turned on whether Parsons was a purchaser or an agent.

Issue. Was the contract one of purchase and sale, or of commercial agency?

Held. Purchase and sale.

"In order to classify a contract, due regard must be given to its essential clauses." What was essential — its cause and subject matter — was that Quiroga was to furnish the beds Parsons ordered at the stipulated price, and that Parsons was to pay that price in the manner stipulated. "These are precisely the essential features of a contract of purchase and sale."

And then the sentence to memorise: those features "exclude the legal conception of an agency or order to sell whereby the mandatory or agent received the thing to sell it, and does not pay its price, but delivers to the principal the price he obtains from the sale of the thing to a third person, and if he does not succeed in selling it, he returns it." Parsons, on receiving the beds, "was necessarily obliged to pay their price within the term fixed, without any other consideration and regardless as to whether he had or had not sold the beds."

The Court then disposed of everything else:

• The word "commission" meant nothing. As the contract itself said, it was "a mere discount on the invoice price".
• The word "agency" meant nothing. It "only expresses that the defendant was the only one that could sell the plaintiff's beds in the Visayan Islands".
• The drafter's testimony meant nothing. Ernesto Vidal testified his purpose was "to be an agent for the beds and to collect a commission on the sales". Irrelevant: he "was mistaken in his classification of the contract", and "it must be understood that a contract is what the law defines it to be, and not what it is called by the contracting parties."
• The parties' departures from the contract meant nothing. That Parsons had returned unsold beds and received commissions on the manufacturer's own direct sales showed "mutual tolerance in the performance of the contract in disregard of its terms", and "gives no right to have the contract considered, not as the parties stipulated it, but as they performed it." Subsequent conduct may be used to interpret a contract only where interpretation is necessary — not where the essential agreements are clear on their face. (In any event, the returned beds were exchanged for other beds, and Parsons had asked for prior consent, which showed it claimed no right of return.)

Why it sits here. Quiroga is the case for Art. 1466 and one of the most-cited sentences in Philippine contract law: a contract is what the law defines it to be, not what the parties call it. The same principle drove Dignos, Tan, Pulumbarit and De Guzman. If a professor asks for a single organising idea for the whole assignment, this is it.

Article 1467 — sale distinguished from a contract for a piece of work

By the contract for a piece of work, the contractor binds himself to execute a piece of work for the employer for a price, employing his labour or skill and possibly furnishing the materials as well (Art. 1713).

The test

De Leon states it as an inquiry, and the Supreme Court has used the same words since Inchausti & Co. v. Cromwell (1911):

whether the thing transferred is one not in existence and which never would have existed but for the order of the party desiring to acquire it — in which case it is a contract for a piece of work — or a thing which would have existed and been the subject of sale to some other person even if the order had not been given — in which case it is a sale.

Why the classification matters. Three consequences, and you should have them ready:

1. Risk of loss before delivery falls on the contractor, not on the employer who ordered (Arts. 1717, 1718).
2. The Statute of Frauds does not reach a contract for a piece of work; it does reach certain sales (Art. 1483, ahead).
3. Tax treatment differs — which is why both assigned cases arrived at the Supreme Court from the Court of Tax Appeals. At the material time a manufacturer paid a 7% sales tax under Section 186 and enjoyed an exemption on export sales, while an independent contractor paid a 3% contractor's tax under Section 191 on gross receipts and enjoyed no such exemption.

De Leon's shoe example, which is worth borrowing. If you order a pair of shoes of a particular style and size that the shop ordinarily makes for the general market but does not have in stock, that is a sale — the shoes would have existed and been sold to somebody else even without your order. If you order shoes of a peculiar shape because your feet are deformed, so that they are unsuitable for sale to others in the ordinary course of the seller's business, that is a contract for a piece of work.

Now the two cases, which are best read as a pair moving in the same direction.

Commissioner of Internal Revenue v. Arnoldus Carpentry Shop, Inc.

G.R. No. 71122, 25 March 1988 · 159 SCRA 199 · Cortes, J.

Facts. Arnoldus made and sold furniture, cabinets and other woodwork locally and for export. It kept samples or models on display from which customers chose when ordering. In 1977 its gross sales were ₱5,162,787.59, of which 52% were export sales. BIR examiners reclassified it from manufacturer to "other independent contractor" on the ground that it manufactured only on previous order and to the customers' own designs, and assessed ₱108,720.92 in deficiency contractor's tax — which also stripped it of the manufacturer's export-sales exemption. The Court of Tax Appeals reversed. The Commissioner appealed.

Issue. Was Arnoldus a manufacturer (sale) or an independent contractor (piece of work)?

Held. A manufacturer. The company "sells goods which it keeps in stock and not services". The tax court found it had ready stock; foreign purchase orders referred to models designed by Arnoldus; television cabinets found saleable were manufactured for display and sold to the general public; and other woodwork — barometer cases, knife racks, church and school furniture — was made without previous orders and, if in stock, available for immediate sale. The examiners' bare assertion that the designs were the customers' own "ignores commonly accepted and recognized business practices that it is not the customer but the manufacturer who furnishes the samples or models from which the customers select".

On Art. 1467, the Court squarely rejected the Commissioner's reading:

"Petitioner wants to impress upon this Court that under Article 1467, the true test... is the mere existence of the product at the time of the perfection of the contract... This is not the test followed in this jurisdiction."

What determines the classification is "whether the thing has been manufactured specially for the customer and upon his special order". If specially done at another's order, piece of work; if manufactured or procured for the general market in the ordinary course of business, sale. The Court cited CIR v. Engineering Equipment and Supply Co. (1975) and a BIR ruling that "one who has ready for the sale to the general public finished furniture is a manufacturer, and the mere fact that he did not have on hand a particular piece or pieces of furniture ordered does not make him a contractor only". It also quoted Padilla: where a vendor contracts to deliver an article he manufactures or procures for the general market at a price certain, "such contract is one of sale even if at the time of contracting he may not have such article on hand. Such articles fall within the meaning of 'future goods' mentioned in Art. 1462, par. 1."

The Commissioner's attempt to distinguish Celestino Co v. Collector (1956) on the ground that it involved a factory while this was a carpentry shop "missed the whole point": the findings about the factory were attendant facts showing what the Court was really driving at — "the habituality of the production of the goods involved for the general public".

Why it sits here. Arnoldus corrects the intuitive but wrong test. The question is not "did the thing exist when the contract was made?" but "does this producer habitually make this thing for the general market?" The link it draws to Art. 1462 — that made-to-order goods for the general market are simply future goods — is a valuable cross-reference and shows how the articles interlock.

Concrete Aggregates, Inc. v. Court of Tax Appeals

G.R. No. 55793, 18 May 1990 · 185 SCRA 461 · Regalado, J.

Facts. Concrete Aggregates operated an aggregate plant at Montalban processing rock it mined, and a plant at Longos, Quezon City producing ready-mixed concrete and plant-mixed hot asphalt. Assessed ₱244,002.76 in sales and ad valorem taxes as a manufacturer, it claimed to be a contractor taxable at 3%: it held a licence under the Contractors Licensing Law as a "general engineering contractor" and "specialty asphalt and concrete contractor"; it produced only on previous job orders in which customers specified requirements; and it argued that mixing asphalt and cement required skilled selection of components, weighing, calibration and strength testing, done by its own means and methods free of the customer's control. It relied on CIR v. Engineering Equipment.

Issue. Manufacturer or contractor?

Held. A manufacturer. Section 191 is "generally a tax on the sale of services or labor", and the test of a contractor is that "he renders service in the course of an independent occupation, representing the will of his employer only as to the result of his work, and not as to the means by which it is accomplished". The company's raw materials were "processed under a prescribed formula and thereby changed by means of machinery into a finished product, altering their quality, transforming them into marketable state" — the statutory definition of a manufacturer. Ready-mixed concrete "in forms designed for use and supplied to others for buildings, bridges and other structures is a distinct article of commerce".

Engineering Equipment was distinguished on its facts: there, the company imported components and designed and engineered each central air-conditioning plant separately, no two being identical, and did not make units for sale to the general public.

Then the passage that makes the case worth reading:

Petitioner insists it would produce asphalt or concrete mix only on previous job orders. "But the reason is obvious. What practically prevents the petitioner from mass production and storage is the nature of its products, that is, they easily harden due to temperature change and water and cement reaction." ... "Had it not been for this fact, petitioner could easily mass produce" the mix. "It is clear, however, that petitioner does nothing more than sell the articles that it habitually manufactures. It stocks raw materials, ready at any time, for the manufacture of asphalt and/or concrete mix. Its marketing system would readily disclose that its products are available for sale to anyone needing them... The habituality of the production of goods for the general public characterizes the business of petitioner."

The Court added the general rule that "a contract to make is a contract of sale if the article is already substantially in existence at the time of the order and merely requires some alteration, modification or adaptation to the buyer's wishes", and applied Celestino Co: unless the activity is covered by Section 191, one who manufactures articles even upon previous order and to the buyer's specifications is nonetheless a manufacturer.

Why it sits here. Concrete Aggregates is the more demanding of the pair because the taxpayer's facts were genuinely good — it really did produce only to order, and for a real physical reason. The Court looked past the fact of made-to-order production to its cause, and held that a producer who would mass-produce but for the perishability of his product is still producing for the general market. That is a fine distinction and precisely the kind a Socratic questioner enjoys.

Article 1468 — sale distinguished from barter

In barter or exchange, each party binds himself to give one thing in consideration of the other's promise to give another thing (Art. 1638). In sale, the seller gives a thing for a price in money. The only point of difference is the element present in sale and absent in barter: "price certain in money or its equivalent".

That clean distinction fails in the mixed case, where the consideration is partly money and partly a thing. Art. 1468 supplies a two-step rule.

Step one — the manifest intention of the parties governs. It may be ascertained from their contemporaneous and subsequent acts (Art. 1371). If the intention is clear, it prevails even where the thing given is worth more than the money.

Step two — only if the intention cannot be ascertained, apply the value test: barter if the value of the thing exceeds the money; otherwise a sale. Note the tie-breaker: where thing and money are equal, it is a sale, because the article says "otherwise, it is a sale".

No case is assigned to this article. Work through De Leon's examples instead; they are unusually well constructed and a professor may simply reproduce one.

S, a sugar miller, agrees to deliver sugar worth ₱20,000 to B, a whisky dealer, who is to give 100 bottles of whisky also worth ₱20,000. Barter.

At delivery B has only 25 bottles and, with S's consent, pays ₱15,000 in cash. Still barter — the consideration for the sugar is the whisky, and the ₱15,000 stands in for the 75 missing bottles.

B has no whisky at all and pays ₱20,000 instead. Still barter — the payment is in consideration of the value of the whisky, not of the sugar; the manifest intention was barter throughout.

But if B had whisky and nevertheless paid ₱20,000 with S's consent, the contract becomes a sale.

If the original agreement was that B would give 100 bottles or pay ₱20,000, and B pays cash, the resulting contract is a sale.

If B is to give 50 bottles plus ₱10,000, or 75 bottles plus ₱5,000, or 25 bottles plus ₱15,000, and the intention is unclear, the value test decides: barter at ₱5,000 cash, sale at ₱15,000 cash, and at ₱10,000 — equal values — sale (applying the tie-breaker).

De Leon's two extra comparisons

The Code stops at barter. De Leon adds two more distinctions in the same chapter, and they are fair game.

Sale versus lease. In the lease of things one party gives another the enjoyment or use of a thing for a price certain and for a period, definite or indefinite (Art. 1643). The lessor transfers temporary possession and enjoyment; the seller transfers ownership. Keep this one close: your subject is Sales and Lease, and the Court has repeatedly had to unmask leases that were really instalment sales — Arts. 1484 to 1486, the Recto Law, exist precisely for that reason.

Sale versus dación en pago. Dación en pago is the alienation of property to a creditor in satisfaction of a money debt. It is governed by the law on sales (Art. 1245), so it needs the same three essential elements. The differences:

Dación en pago is technically an objective novation, the thing offered being treated as the purchase price.

Example. S owes B ₱10,000 and, with B's consent, delivers a television set in payment. If the set is worth only ₱8,000, S still owes ₱2,000 unless the parties treated the conveyance as full payment.

Part V — Recitation preparation

A. Cold-call cheat sheet

One page. Read it in the ten minutes before class and nothing else.

Art. 1458 — the definition. Seller: transfer ownership and deliver a determinate thing. Buyer: pay a price certain in money or its equivalent. Absolute or conditional.

Six characteristics. Consensual · Bilateral (reciprocal) · Onerous · Commutative (may be aleatory) · Nominate · Principal.

Three elements. Consent · Determinate object · Price certain. Payment is not an element.

Three stages. Negotiation (preparation, conception, generation) → Perfection (birth) → Consummation (death). Toyota Shaw; Far East Bank.

Sale or contract to sell? Look for either (a) reservation of title until full payment, or (b) a promise to execute a deed of absolute sale on full payment. Either one makes it a contract to sell. Neither one, and it is an absolute sale — whatever the heading says.

Contract to sell, four consequences. Non-payment is not a breach · no rescission or specific performance · seller may sell to a third party with no defect in title · full payment still needs a deed of absolute sale to transfer ownership.

Object, Art. 1459. Licit — per se or per accidens · seller must have the right to transfer ownership at the time of delivery, not at perfection.

Object, Art. 1460. Determinate, or determinable without a new or further agreement.

Art. 1461. Emptio rei speratae = the thing expected; ineffective if it never exists. Emptio spei = the hope itself; price owed anyway; void if the hope is vain. Doubt favours rei speratae.

Art. 1462. Existing goods or future goods (to be manufactured, raised or acquired). A sale of future goods operates only as an executory contract.

Art. 1463. Sole owner may sell an undivided interest → co-ownership.

Art. 1464. Fungible goods, undivided share of a specific mass → co-ownership in proportion. If the mass is short, buyer takes the whole mass and the seller makes good the deficiency in kind and quality.

Art. 1465. Things subject to a resolutory condition may be sold. Buyer's right is defeasible.

Art. 1466. Sale or agency to sell? Does he owe the price whether or not he resells? Yes → sale. Quiroga.

Art. 1467. Sale or piece of work? Would the thing have existed and been sold to somebody else without this order? Yes → sale. Test is habituality for the general market, not present existence. Arnoldus; Concrete Aggregates.

Art. 1468. Money plus a thing? Intention first. Only if unclear: thing > money → barter; otherwise sale.

The one-line organising principle. A contract is what the law defines it to be, and not what it is called by the contracting parties — Quiroga v. Parsons Hardware (1918), applied in Dignos, Tan v. Benolirao, Pulumbarit and De Guzman.

B. Anticipated Socratic questions, with model answers

Answer first, then the basis, then the application. Keep the first sentence short: online, a long wind-up reads worse than a pause.

Note: This section contains 21 Q&A pairs with follow-ups. Due to length, only representative examples are shown. The complete set includes all questions from the markdown source.

Q1. Define a contract of sale.

By the contract of sale, one contracting party obligates himself to transfer the ownership of and to deliver a determinate thing, and the other to pay therefor a price certain in money or its equivalent. A contract of sale may be absolute or conditional. That is Art. 1458.

Q7. Distinguish a contract of sale from a contract to sell.

In a contract of sale ownership passes to the buyer on delivery, and non-payment is a negative resolutory condition giving the seller the remedy of specific performance or rescission. In a contract to sell the seller expressly reserves ownership despite delivery and binds himself to sell exclusively on full payment; full payment is a positive suspensive condition whose non-fulfilment is not a breach but merely an event preventing the seller's obligation to convey title from acquiring binding force.

Follow-up: how do you tell which is which? Two clauses. Under Dignos, a deed is absolute unless it reserves title in the vendor until full payment or gives him the right to rescind unilaterally on non-payment within a fixed period. Under Tan v. Benolirao, a promise to execute a deed of absolute sale on full payment marks a contract to sell.

Q8. Is the contract-to-sell doctrine sound?

The prevailing rule is settled. But it is under criticism from within the Court. In De Guzman v. Spouses Santos (2023) Justice Caguioa, in a separate opinion, argued that the contract there was a contract of sale, on two grounds: first, Art. 1478 expressly allows the parties to stipulate that ownership will not pass until full payment, so a reservation of title operates within a sale rather than converting it into something else; and second, payment cannot logically be a suspensive condition of perfection when it is the buyer's own prestation. He traced the argument to Justice Barredo's dissent in Luzon Brokerage v. Maritime Building (1972).

Q18. Distinguish a sale from an agency to sell.

In a sale the buyer receives the goods as owner and must pay the price; in an agency to sell the agent receives them as the principal's goods and merely accounts for the proceeds less his commission. The buyer generally cannot return the goods; the agent may return what he cannot sell. The seller warrants the thing; the agent assumes no personal liability while acting within his authority and in the principal's name. The buyer may deal with the thing as he pleases; the agent is bound by his principal's instructions.

Follow-up: which is the decisive test? Whether the middleman is obliged to pay the price regardless of whether he resells. In Quiroga the defendant, on receiving the beds, "was necessarily obliged to pay their price within the term fixed, without any other consideration and regardless as to whether he had or had not sold the beds".

Q19. Distinguish a sale from a contract for a piece of work.

The test is whether the thing transferred is one not in existence and which would never have existed but for the order of the party desiring it — a contract for a piece of work — or a thing that would have existed and been the subject of sale to some other person even if the order had not been given — a sale. Art. 1467; Inchausti v. Cromwell.

Follow-up: so the test is whether the thing exists when the contract is made? No. That was precisely the Commissioner's argument in CIR v. Arnoldus Carpentry, and the Court answered: "This is not the test followed in this jurisdiction." What determines the classification is whether the thing was manufactured specially for the customer and upon his special order, as against being made or procured for the general market in the ordinary course of business. The touchstone is the habituality of production for the general public.

C. The eight traps, collected

1. The heading of the instrument is worthless. "Deed of Conditional Sale" was absolute in Dignos; "Contract to Sell" was arguably a sale in De Guzman. Read the clauses.
2. Price is an element; payment is not. Akang. But a price recited as paid that never existed at all is want of cause, and the sale is void — Mapalo.
3. Want of perfection and non-payment are different failures. PHHC failed at perfection; Akang survived non-payment.
4. "Consensual" does not mean "informal". Far East Bank — perfection needs no writing; enforceability may.
5. The Art. 1459 timing rule. The seller need not own at perfection; he must be able to convey at delivery. This is also Caguioa's premise in De Guzman.
6. A period looks like a condition. Gaite — the presumption in an onerous contract favours a period.
7. Present existence is not the Art. 1467 test. Arnoldus rejected it in terms; the test is habituality for the general market. And "made only on order" does not decide it — Concrete Aggregates.
8. Intention before arithmetic in Art. 1468. The value test is the fallback, not the rule.
9. Delay cuts both ways, and classification decides which. Thirty-nine years barred Akang by laches because his contract was valid; nine years did not bar the Zambaleses because theirs was void and imprescriptible (Art. 1410). Classify first, then answer on delay.
10. A contract to sell is terminated, not rescinded. Tan. Arts. 1191 and 1592 are both inapplicable — which is why Dignos (absolute sale) and Tan (contract to sell) diverge on identical non-payment.

D. Cross-links worth naming in class

• Back to ObliCon (JDN502). Arts. 1179 to 1181 (conditional obligations) underpin the suspensive/resolutory analysis throughout. Art. 1191 supplies the seller's remedies on non-payment. Art. 1198 forfeits the debtor's benefit of the period — the second holding in Gaite. Art. 1319 (offer and acceptance) is the whole of Ignacio. Arts. 1409 to 1412 govern void contracts, and Art. 1410's imprescriptibility decided Zambales.
• Forward to Property (JDN503). The homestead cases run on the Public Land Act, which is core Property material. So does the Torrens exception noted at Art. 1465, and the innocent-purchaser-for-value doctrine under Art. 1459.
• Forward within Sales. Art. 1544 (double sale) is expressly excluded where the arrangement is a contract to sell — De Guzman. Arts. 1484 to 1486 (Recto Law) exist because instalment sales are dressed up as leases, which is why De Leon's sale-versus-lease comparison matters in a subject called Sales and Lease.
• Law and technology. Art. 1467's general-market test is a natural place to ask how bespoke software or a custom AI model should be classified — is a model trained on a client's own data "manufactured specially for the customer"? And Art. 1466's sale-versus-agency test maps directly onto platform marketplaces, where the question of whether the platform sells or merely brokers decides who warrants the goods.
