Understanding Your Escritura: How to Read a Mexican Property Deed

Your escritura is the most important document you will own in Mexico. Not your fideicomiso contract, not your purchase agreement — your escritura. It is the public deed that proves ownership, prepared by the notario público and registered with the Public Registry. Most foreign buyers sign it without reading it. I have watched buyers close on million-dollar properties after spending more time choosing a restaurant than reviewing their deed. This guide fixes that.

What an Escritura Actually Is

An escritura pública is a formal public deed prepared, authenticated, and registered by a notario público. In Mexico, the notario is not the equivalent of a US notary — they are a government-appointed legal official with the exclusive authority to authenticate certain legal acts, including property transfers. Think of them as a combination of a notary, a tax collector, and a title officer, but with government authority and personal liability for the accuracy of the documents they prepare.

The escritura does three things simultaneously:

• Transfers ownership from the seller to the buyer (or, in the case of a foreign buyer in the restricted zone, establishes the fideicomiso with the bank as trustee and you as beneficiary)
• Creates a tax event — the notario calculates and collects the acquisition tax (ISAI), income tax on the seller's gain, and their own notarial fees
• Registers the transfer with the Public Registry of Property, making it a matter of public record

Without a registered escritura, your purchase agreement and your fideicomiso contract are private arrangements with no public legal standing. The escritura is what makes the transaction real in the eyes of Mexican law.

The Sections of an Escritura (What to Read and Why)

1. Identification of Parties (Comparecientes)

The opening section identifies every party to the transaction: the seller, the buyer (or the bank as fideicomiso trustee and you as beneficiary), the notario, and any legal representatives acting under power of attorney. For foreign buyers, this section should include your full legal name exactly as it appears on your passport, your nationality, your Mexican tax ID (RFC) if you have one, and your immigration status.

What to verify: Your name is spelled correctly — exactly as on your passport. This sounds trivial, but a name mismatch between your escritura and your fideicomiso creates legal complications that require a corrective escritura (additional notario fees and 2–3 months of processing). If you have a hyphenated name or multiple surnames, confirm the notario has it right.

2. Property History (Antecedentes)

This section traces the chain of title — the history of ownership transfers that led to the current seller's right to sell. It references prior escrituras, registration numbers, and dates. For new construction purchased directly from a developer, this section traces the developer's original land acquisition, subdivision, and condominium regime creation.

What to verify: The chain of title should be unbroken and clean. Your attorney should cross-reference these antecedents with the title search performed during due diligence. Any gaps, inconsistencies, or references to disputed transactions are red flags that must be resolved before closing.

3. Property Description (Descripción del Inmueble)

The legal description of the property including its location, lot number, metes and bounds (colindancias), total area in square meters, and any structures. For condominiums, this section identifies the specific unit within the condominium regime (régimen de propiedad en condominio), the percentage of common area ownership, and any assigned parking or storage spaces.

What to verify: The square meters match your purchase agreement and the survey (if one was performed). The unit number is correct. The common-area percentage matches the condominium regime documents. If you are buying a lot, walk the boundaries with a surveyor and compare their measurements to the escritura description. Discrepancies in property dimensions are among the most common escritura errors and can affect your property tax basis, your building rights, and even your actual usable area.

4. Price and Tax Declarations (Precio y Declaraciones Fiscales)

This section states the purchase price (in both pesos and USD, with the exchange rate used for conversion), the catastral value assigned by the municipality, the appraised value, and the tax calculations. The notario uses the higher of the catastral, appraised, or declared value to calculate taxes.

What to verify: The purchase price matches your agreement. The catastral value is reasonable (typically below market value, but not suspiciously low — which could trigger a tax audit). The exchange rate is current. The ISAI (acquisition tax) calculation is correct — in Baja California Sur, the rate was raised to approximately 3% effective 2025. The total closing costs listed should match the estimate your notario provided during escrow.

5. Fideicomiso Establishment (For Foreign Buyers)

For purchases in the restricted zone (within 50 km of coastline — which includes all of Los Cabos), this section establishes or assigns the fideicomiso. It identifies the trustee bank, the trust number, the beneficiary (you), your rights under the trust, and the term (50 years, renewable). If you are being assigned an existing fideicomiso from the seller, it records the assignment.

What to verify: The bank name and trust number are correct. Your rights as beneficiary are explicitly stated: the right to use, rent, improve, pledge, and sell the property. The term start date is clearly stated (it matters for renewal timing). If this is an existing fideicomiso assignment, confirm the annual fees are current — you do not want to inherit unpaid trust maintenance fees.

6. Conditions and Encumbrances (Gravámenes)

Any liens, mortgages, easements, or restrictions on the property are disclosed here. A clean escritura states "libre de todo gravamen" — free of all encumbrances. If encumbrances exist, they must be described in detail and either resolved before closing or explicitly assumed by the buyer.

What to verify: The property is declared free of encumbrances, or any existing encumbrances are known to you and acceptable. This should match the results of your title search. Undisclosed liens that appear after closing become your problem — this is why independent title insurance exists and why I recommend it for every transaction.

Common Escritura Errors That Cost Buyers

In my experience working with Los Cabos closings, these are the most frequent escritura errors and their consequences:

• Name misspelling: Your name must match your passport exactly. "Steven" vs. "Stephen," "MacDonald" vs. "McDonald" — these create mismatches with your fideicomiso, bank accounts, and tax filings. Correcting requires a new escritura (clarificación), costing $500–$1,500 in notario fees plus 2–3 months.
• Incorrect square meters: Especially common in new construction where the as-built dimensions differ from the architectural plans used in the preliminary escritura. Verify against the final survey. An error of even 5% affects your catastral value, tax basis, and the accuracy of any future sale.
• Wrong catastral value: If the catastral value is set too low, your property taxes will be artificially low — but you may face penalties when the municipality reassesses, and the underdeclared value can complicate a future sale. If set too high, you overpay predial from day one.
• Missing condominium regime reference: For condo purchases, the escritura must reference the condominium regime (régimen de propiedad en condominio) number. Without this, your unit's relationship to common areas, CC&Rs, and HOA governance is legally undefined.
• Fideicomiso term confusion: The 50-year term starts from the date the fideicomiso was originally established, not the date of your purchase. If you are buying an existing fideicomiso from a seller who established it in 2010, you have 34 years remaining on the original term — with the right to renew for additional 50-year periods. Verify the start date.

After Signing: What Happens Next

Once you sign the escritura at the notario's office, the process is not complete. The notario must:

1. Collect all taxes (ISAI acquisition tax, seller's capital gains tax) and submit to the tax authorities
2. Submit the escritura to the Public Registry of Property for registration
3. Register the fideicomiso with the Secretary of Foreign Affairs (SRE) if this is a new trust

Registration typically takes 30–90 days. During this period, the notario should provide you with a certified copy of the signed escritura for your records. The original registered escritura — with the Public Registry stamp — arrives after processing and should be stored in a safe deposit box. This is the single most important document related to your Mexican property ownership.
