The single most important document in a Mexican property purchase is the escritura pública — the public deed. Skip the wrong step here and you can lose the property, the money, or both. Here's what every buyer should understand before signing anything.
What is an escritura?
An escritura is the legal document that transfers ownership of real property in Mexico. It must be:
- Notarized by a public notary (notario público)
- Registered in the Public Registry of Property (Registro Público de la Propiedad) for the state where the property is located
A property without a properly registered escritura is, legally, not yours — even if you "bought" it.
The notario's role
Mexican notarios are not paralegals. They are highly trained attorneys appointed by the state government with quasi-judicial authority. Their job:
- Verify the seller's identity and legal capacity to sell
- Confirm the property exists, is correctly described, and is registered to the seller
- Calculate and collect taxes (ISR for the seller, ISAI for the buyer)
- Draft the escritura
- Witness signatures
- Register the new escritura with the Registro Público
Their fee runs 2–4% of the purchase price and is non-negotiable for what they're delivering. The buyer chooses the notario. Don't let the seller pick — you want a notario working for your interests.
Types of escrituras you'll encounter
Escritura de compraventa
The most common — a deed of purchase and sale. This is what you want.
Escritura de donación
Gift deed (between family members). Tax treatment is different. Not common in arms-length sales.
Escritura de fideicomiso
Bank trust deed. Required for foreign buyers in the restricted zone (within 50km of the coast or 100km of the border). The bank holds title; you have full beneficial rights to use, rent, sell, and inherit.
Cesión de derechos
Assignment of rights. Avoid these for buying. This is not real ownership — it's an assignment of someone else's claim. Common in informal markets and ejido land. If a seller offers only a cesión, walk away or get a real lawyer.
Documents to verify before closing
Have your notario or a separate real-estate lawyer confirm:
- Certificado de libertad de gravamen — the property has no liens, mortgages, or claims
- Boleta predial paid up to date (property tax)
- Boleta de agua paid up to date (water service)
- Maintenance fees for condominiums paid up to date
- No outstanding utility debts (CFE, gas)
- Land use matches what you're buying (residential, commercial)
- Surface area in the deed matches the actual property — physically measure
- Access rights (easements, right-of-way) clearly stated
Get all of these in writing before you sign.
Common red flags
"We don't have the escritura yet but the deal is good"
Walk away. You're being asked to buy from someone who doesn't legally own the property.
Properties priced 30%+ below market
Always investigate. Often a sign of legal problems, family disputes, or land that can't be transferred cleanly.
Pressure to skip the notario or use the seller's notario
This is the single biggest scam vector in Mexican real estate. Refuse, always. The buyer chooses the notario.
Verbal promises about "fixing" the deed later
The deed must be clean before you sign. Promises to fix things post-sale are how buyers lose properties.
Ejido land sold "to be regularized"
Don't buy ejido (collective rural) land that hasn't been formally privatized. The process to regularize can take years and costs more than the property is worth.
The closing process — step by step
- Offer accepted, deposit paid (usually 10% in escrow at the notario's office)
- Due diligence period (15–30 days) — your notario or lawyer pulls all required documents
- Title insurance (optional but recommended for high-value properties)
- Tax calculation — notario calculates ISR for seller and ISAI for buyer
- Final closing meeting — all parties sign the escritura at the notario's office
- Funds released to the seller
- Notario submits to Registro Público — registration takes 1–4 weeks
- You receive a registered original of the escritura
Until step 8 is complete, keep all documents. The unregistered escritura is not yet legally binding against third parties.
Costs to expect
For a $4,000,000 MXN property purchase:
- Notary fees: ~$80,000–160,000 MXN (2–4%)
- ISAI (transfer tax, paid by buyer): $80,000–200,000 MXN (varies by state, 2–5%)
- Registry fees: ~$10,000–25,000 MXN
- Appraisal (avalúo): $5,000–10,000 MXN
- Title search: $2,000–4,000 MXN
- Total closing costs: roughly 5–8% of the purchase price
Budget for it. Surprise closing costs are how buyers run out of cash mid-transaction.
What about a fideicomiso?
If you're a foreign buyer in the restricted zone, you'll buy through a fideicomiso. The structure:
- You = beneficiary with all economic rights
- The Mexican bank = trustee that holds nominal title
- The seller = transfers to the trust
A fideicomiso is renewable for 50 years at a time, indefinitely. Annual fees are $400–600 USD. You can sell, rent, remodel, mortgage, and pass to heirs — exactly like a Mexican owner.
Fideicomisos are a normal, well-trodden path. Tens of thousands of foreign buyers use them. Don't avoid the restricted zone purely because of the fideicomiso requirement — just budget the setup and annual fees into your math.
Final advice
Mexican property law is generally protective of legitimate buyers. The system works when followed. Most disasters happen when buyers skip steps to save money or because a seller pressures them. Don't skip steps. Use a notario you chose. Verify every document. Wait for registration. Then enjoy your new home.
