In short
Article 1274 of the Civil Code of 2020 defines the contract: by the sale, the selling party binds itself to transfer to the buying party the ownership of a thing, and the latter binds itself to pay a certain price. Article 1275 settles the mixed deal, where something is handed over and money on top: when part of the price consists of money and the other part of another thing or right, the contract is a sale provided the value of the money is equal to or greater than that of the other thing or right. Article 1276 says how far these rules reach: they apply suppletorily to contracts generating the obligation to constitute, modify or transfer real rights over things or rights, including instruments of credit, and also to contracts giving rise to the obligation to deliver things that will be manufactured or built, except where the party ordering them assumes the obligation to provide a substantial portion of the materials; and they are inapplicable to contracts for the provision of services. As to form, Article 1285 is broad: the sale requires no special formality for its validity, except where a special statute so requires. And Article 1286 closes the circle: in the modifications of an already perfected contract, the same formalities as in the original execution shall be observed.
What is it?
They are Articles 1274 to 1276 and 1285 to 1286 of the Civil Code of 2020, which open and internally order the chapter on sales: what the contract is, when a mixed deal is still a sale, which other contracts its rules reach, and what form it requires.
Who can do it?
Anyone buying or selling a thing in Puerto Rico under the Civil Code, and anyone who made a mixed deal of thing plus money and needs to know how it is classified.

Step by step
Step 1: The definition, word for word
Article 1274: by the contract of sale, the selling party binds itself to transfer to the buying party the ownership of a thing, and the latter binds itself to pay a certain price. Two obligations, one on each side.
Step 2: Thing plus money: the deciding rule
Article 1275 addresses the ordinary trade-in-plus-cash case. When part of the price consists of money and the other part of another thing or right, the contract is a sale provided the value of the money is equal to or greater than that of the other thing or right. If the money is worth less, the article does not call it a sale.
Step 3: How far the rules of sale reach
Article 1276 applies them suppletorily to contracts generating the obligation to constitute, modify or transfer real rights over things or rights, including instruments of credit. Suppletorily means they step in where the contract and its own law say nothing.
Step 4: Things to be manufactured or built
The same article reaches contracts giving rise to the obligation to deliver things that will be manufactured or built, with one exception: where the party ordering them assumes the obligation to provide a substantial portion of the materials. The Code does not define "substantial portion", and this guide sets no percentage the article does not carry.
Step 5: Services are left out
The last line of Article 1276 is categorical: the rules of sale are inapplicable to contracts for the provision of services. A services contract is not resolved with this chapter.
Step 6: Form: none, unless a special statute asks for it
Article 1285: the contract of sale requires no special formality for its validity, except where a special statute so requires. The article refers to those statutes without naming them, and neither does this guide, because it did not read them here. Note: the Code itself, in another chapter, does require certain dealings to be put in writing, and that has its own guide.
Step 7: To change what was signed, the same formality
Article 1286: in the modifications of an already perfected contract, the same formalities as in the original execution shall be observed. If the sale was made by public deed, the modification calls for the same.
Where to do it
A sale is executed between the parties; the Code does not order anyone to go to an agency for it to exist. If the thing is real property and registration is wanted, that is governed by the Property Registry and its statute, which we did not read here. Disputes are decided by the Court of First Instance.
How long it takes
What to do if something goes wrong
If what you contracted was a service and not the delivery of a thing, Article 1276 leaves this chapter out. If the problem is a defect in the thing bought, that is warranty and hidden defects, with its own guide. If the problem is who could sell, or what may be sold, see the guide on legitimation and object. This chapter does not say which special statutes impose formalities, nor what a "substantial portion of the materials" is, nor how a sale is registered. MiPRFácil does not represent anyone in court and gives no legal advice.
Common mistakes
- Believing there is no sale without a signed document: Article 1285 requires no formality unless a special statute asks for it.
- Believing the opposite, that form is never needed: the special-statute proviso is part of the same article.
- Calling every deal with a thing in it a barter: if the money is worth the same or more, it is a sale.
- Calling a sale the deal in which the money is worth less than the thing handed over.
- Modifying orally a contract executed with formalities: Article 1286 requires the same ones as the original execution.
- Applying the rules of sale to a contract for the provision of services.
- Assuming a numeric rule for "substantial portion of the materials": the Code gives none.
- Assuming the price must be entirely in money: Article 1275 admits the mixed deal.
Frequently asked questions
I handed over my car and added money. Is it a sale or a barter?
It depends on the values. Article 1275 says it is a sale provided the value of the money is equal to or greater than that of the other thing or right.
Does a sale have to be in writing?
Article 1285 says it requires no special formality for its validity, except where a special statute so requires. Which statutes those are is not stated in this article, and this guide does not invent them.
I ordered something that must be manufactured. Do the rules of sale apply?
Yes, under Article 1276, except where the ordering party assumes the obligation to provide a substantial portion of the materials. The Code does not define that portion.
We want to change the contract already signed before a notary. Is an email enough?
Article 1286 orders that modifications observe the same formalities as the original execution.

Did you find out-of-date information?
Who may not buy and what may in fact be sold
Officials and judges, arbitrators, mediators, attorneys, procuradores and prosecutors face prohibitions. And a future or another’s thing may indeed be sold.
What the seller must do and what the buyer must do
Seven duties for the seller and six for the buyer, plus the warranty deadlines: four years for immovables, six months for movables.
The thing bought was destroyed: until when the risk is the seller’s
Risk does not pass to the buyer until the seller places the thing at their disposal. If shipping was requested, it passes on handing it to the carrier.
What you sign has the force of law: the limits of freedom to contract
You may contract or not, and with whom you like, but not abusively. And what the contract omits is filled by law, usage and good faith.
Which deals must be put in a document, and the one the law forbids
Five cases must appear in a public or private instrument for evidentiary purposes. And a contract on a future inheritance is forbidden.
You bought something with a hidden defect: what you can claim
Whoever transfers an asset for value answers for eviction and hidden defects even if unaware of them. But the defect claim prescribes in 6 months.
