This guide on contrato de promesa Mexico deals explains what the document must contain before you pay anything, why it binds you, and what to have reviewed first. Most foreign buyers in Puerto Vallarta and Bahía de Banderas first meet the promise agreement when a seller asks for a deposit before a notary is involved. It looks like a formality, just a few pages and a signature. In practice, it is often the only document protecting your money until the final deed is signed, sometimes months later.

Quick Takeaways
| Key Insight | Explanation |
|---|---|
| Put every business term in writing | Price, deposit amount, installment dates, closing date, and closing conditions must appear in the contract. A term left as “to be agreed” is a future dispute. |
| Check title before the deposit moves | Ask for a current Public Registry certificate and match the seller’s name to their passport. A mismatch is the fastest way to learn a deal will not close. |
| Build the fideicomiso into the promise | Foreign buyers within about 50 km of a coast must hold property through a bank trust. The promise should name the trust and its role in payment and closing. |
| Use a neutral escrow agent | Never send a deposit to an agent’s or lawyer’s personal account. Use an independent escrow arrangement with written release conditions. |
| Get closing costs in writing | Closing costs are often estimated at roughly 6 to 10 percent of the purchase price. On a $400,000 USD property, that is $24,000 to $40,000 USD. |
| Define what happens if the deal stalls | State who may extend deadlines and whether the deposit is returned, forfeited, or applied to the price if either party walks away. |
| Have your own lawyer review before signing | The notary handles formalities and tax filings for the transaction. Only your own lawyer works exclusively for your interests. |
What a Promissory Purchase Agreement Is in Mexico
A promissory purchase agreement, known in Spanish as a contrato de promesa de compraventa, is a written commitment by the seller to sell and by the buyer to buy a specific property on agreed terms. The transfer itself happens later, when the parties sign the deed before a notary and the notary files it with the Public Registry. Until then, the promise holds the deal together.
Mexican practitioners use it for a simple reason. Due diligence, financing, fideicomiso setup, and tax calculations take time, and no buyer should hand over a deposit with nothing on paper. The civil codes of the Mexican states generally recognize these agreements, and they bind the parties when they contain the essential business terms.
The Promise Is Not the Deed
A common mistake is treating the promise as if it transfers ownership. It does not. Title moves only when the final deed is executed and registered, which is why the notary’s role matters so much at the end of the process.
Your promise sets the rules for getting there. It should say what each side must do, in what order, and what happens if one side does not perform. If it says none of that, you have a letter of good intentions, not a protected purchase.
Who Benefits Most From a Written Promise
Buyers who expect a short, simple closing benefit least from a promise, because the deed can be signed quickly. Buyers of luxury homes, condos with complex histories, or properties held by companies benefit the most. Those deals need time, and time without a written promise is exposure.
What Must Be in the Contract to Make It Stick
Property, Price, and Payment Terms
The contract needs a precise description of the property, including its legal description and registry information, not just a street address. It should state the purchase price and how the deposit and each installment will be paid. Vague payment language is where most disputes start.
Ask for the deposit schedule in writing and confirm whether funds go into an escrow account or directly to the seller. We regularly see drafts that name a deposit “to be agreed” and leave the number blank. That gap invites a fight later, when the buyer has the least leverage.
Conditions, Dates, and Exit Terms
Conditions precedent are the requirements that must be met before closing, such as a clean title certificate, delivery of the seller’s documents, and the buyer’s fideicomiso approval. List each one separately. A condition that is not written down cannot protect you when the seller insists the deal is done.
Set a closing date, and define what happens if it slips. The contract should say who may extend the deadline, in what form, and how the deposit is treated if the deal fails. Silence on these points usually favors the party holding the money.
Pro tip: Before signing, read the cancellation clause twice and ask who keeps the deposit in each scenario. If you cannot answer in one sentence, the clause needs rewriting before you sign.
Why the Promise Comes Before the Deed
The gap between signing a promise and signing the deed is where most of the real work happens. Buyers need time to verify title, obtain tax calculations, arrange payment, and set up a bank trust when required. Foreign buyers within about 50 km of a coast must hold property through a fideicomiso, a trust that runs for 50 years with extensions.
The promise is the place to lock in that structure. If the buyer will hold the property through a trust, the promise should say so, and it should name the bank and the steps needed to open the trust before the deed is signed.
Where the Promise Fits in the Timeline
In practice, the promise is signed after the buyer and seller agree on price, and before or during due diligence, depending on how the seller wants to proceed. Some sellers request a deposit at signing. Others accept a deposit only after the title review is clean. A careful buyer pushes for the second approach.
The notary then formalizes the deed, calculates the taxes the sale triggers, and files the transfer. Our notary guide covers that role in more detail. The point here is that the promise should protect your position until that step happens.
What the Promise Cannot Fix
A promise cannot cure a defective title. If the seller’s name does not match the registry, or an unpaid lien exists, the promise only gives you a claim against the seller, not protection of the asset itself. That is why the promise and due diligence must be reviewed together, not in sequence.
Due Diligence Between Signing and Closing
Once the promise is signed, the buyer usually runs due diligence, which typically includes a title search, a no-lien certificate, zoning verification, a topographical survey, and a review of restrictions such as setbacks, easements, and owners’ association rules. These steps are generally the buyer’s responsibility, and they should be finished before the deposit is released.
Environmental and engineering reviews are worth considering for older buildings and for luxury properties with extensive construction. A clean title is the baseline. Everything else affects value, insurability, and how quickly you can resell.
Title and Registry Checks
Ask for a current Public Registry certificate and match the seller’s name to their passport before paying any deposit. If the seller is a company, check the corporate records and confirm who has authority to sign. A signing officer without authority can void the transaction you thought you had.
Cross-check the registry against the property’s physical boundaries and cadastral records. Discrepancies between the registry, the survey, and the tax records are common enough that they should be expected, and they should be resolved before the deposit is released.
Permits and Restrictions
Zoning and construction rules can change how you use the property. Confirm the permitted use, the permit history, and whether the building matches approved plans. Do this before the promise’s conditions are satisfied, not after you have moved your furniture in.
Deposits, Escrow, and Where the Money Goes
Sellers in Mexico often expect a direct good faith deposit, while buyers assume the money is protected. Those expectations clash. Escrow is rarely offered by default, so you need to request it in writing before paying anything.
An escrow agent is a neutral party that receives the funds, verifies the buyer’s identity, holds the money in a protected account, and releases it only when the agreed conditions are met. Our escrow guide walks through that flow step by step. The promise should name the escrow arrangement and spell out the release conditions.
Deposits to Avoid
Never send a deposit to an agent’s or a lawyer’s personal account. A personal account has no release conditions and no independent record of the transaction. If the money disappears, you are left with a claim against an individual instead of a protected transaction.
Also be cautious about deposits requested in cash or to accounts in a third party’s name. Ask who owns the receiving account, and insist that it match the escrow agreement or the seller’s verified name.
Closing Costs You Should See in Writing
Closing costs in Mexico are often estimated at roughly 6 to 10 percent of the purchase price. On a $400,000 USD property, that range works out to $24,000 to $40,000 USD. The promise should either list who pays which taxes and fees or require a written breakdown before the deposit is released.
The ISAI acquisition tax is set at the municipal level, so the rate can differ by location. Ask for it calculated in writing and check the figure against the purchase price and the cadastral value.
Pro tip: Request the closing cost estimate before you sign the promise, not after. Once a deposit is in motion, the seller has less incentive to explain the numbers in detail.
Comparing Pre-Closing Documents
Buyers often hear about three documents before closing: a promissory agreement, a letter of intent, and a direct move to the final deed. Each does a different job, and choosing the wrong one for your risk level is an expensive mistake.
| Document | What It Does | Main Risk |
|---|---|---|
| Contrato de promesa (promissory purchase agreement) | Binds both parties to a future sale on agreed terms, with conditions and deadlines | Weak if price, deposit, or conditions are missing or vague |
| Letter of intent | Records the main deal points and shows intent to keep negotiating | Often nonbinding, so it gives little protection for a deposit |
| Final deed signed before a notary | Transfers ownership and is filed with the Public Registry | Too late for due diligence if title and taxes were not checked earlier |
Our recommendation is direct. Use a full promise whenever a deposit or a multi-month timeline is involved, and treat a letter of intent only as a framework for negotiation. Do not let money move against a letter of intent alone.
Common Traps for Foreign Buyers in Puerto Vallarta
The most frequent problem we see is a promise signed in one language and understood in another. Ask for a bilingual version, but confirm in writing which language controls. In practice, Spanish is the language that carries weight in Mexican procedures, so the Spanish text needs to say exactly what the English text says.
Verbal Side Agreements
A promise that says nothing about furniture, pool equipment, or a reserved parking space invites disputes at handover. Anything agreed outside the written contract is hard to prove later. Put every inclusion on paper, along with the condition of the property at closing.
Pressure to Sign Quickly
Some sellers set a short deadline to lock in a buyer before due diligence is complete. A short timeline is not a reason to skip checks. A reasonable seller will accept a signing date that follows the title review, and a seller who refuses that point is telling you something important.
Pro tip: Ask the seller to confirm in writing that no other promise, offer, or lien affects the property. A short representation costs the seller nothing and protects you from a double sale.
What a Contract Review Should Cover
A review is more than a language check. It tests whether the promise works with the deed you will eventually sign, the fideicomiso you will hold through, and the tax position you have modeled. If any one of those pieces does not fit, the promise needs changes before you sign.
Matching the Promise to the Fideicomiso
If the buyer will hold the property through a bank trust, the promise should name the trust structure and the trust’s role in payment and closing. Mismatched documents create delays at the bank and at the notary’s table, and delays often cost more than the fee for a proper review.
Checking Remedies and Deadlines
Review every remedy clause and every deadline. Make sure the contract states how a default is declared, how notice must be given, and how long each party has to cure a problem. These clauses decide who pays when a deal goes wrong.

Frequently Asked Questions
Is a contrato de promesa the same as the final deed in Mexico?
No. The contrato de promesa is a binding commitment to sell and buy on agreed terms, while the final deed is signed before a notary and filed with the Public Registry to transfer ownership.
Is a contrato de promesa binding in Mexico?
It can be, when it contains the essential business terms, such as the property description, price, payment terms, conditions for closing, and the closing date. A promise missing those terms gives you far less protection.
Do I still need a promise if I am using a fideicomiso?
Yes. The bank trust is how a foreign buyer holds the property, but the promise is what fixes the price, deposit, conditions, and deadlines before the trust and the deed are finalized.
Should I pay a deposit before the promise has been reviewed?
No. Review the promise, the title documents, and the escrow arrangement first. A deposit paid before those checks gives the seller the advantage in any later dispute.
Can I ask for the contract in English?
Yes, and a bilingual version is a good idea. Confirm which language controls, because the Spanish text is the one that matters in Mexican procedures, and the two versions must match.
