The Notary's Role in Mexico: Different from Other Countries
In Mexico, the notary public is very different from a notary in the U.S. or Canada. The Mexican notary is a government-appointed legal professional with full public faith powers. In a real estate transaction, the notary verifies the legality of the entire operation, withholds and remits taxes to SAT, and registers the transaction at the Public Property Registry.
This means the notary is, in many ways, the buyer's strongest protection in Mexico.
Stage 1: Promise of Purchase Contract
Before reaching the notary, parties typically sign a Promise of Purchase Agreement. This establishes price, payment terms, dates, conditions and penalties. For presales, this is the main document throughout construction. The initial deposit (typically 10–20% of price) is paid at signing.
Stage 2: Notarial Due Diligence
Once the promise is signed, the notary begins due diligence:
- Lien-free certificate from the Public Property Registry
- Verification that the seller is the legitimate titleholder
- Land use and zoning review
- Confirmation of current property tax payments
- Full title study (property history)
- For fideicomiso: processing the permit with the Ministry of Foreign Affairs (SRE)
This stage takes 4–8 weeks depending on property complexity.
Stage 3: SRE Permit (Restricted Zone Properties Only)
For coastal properties, the notary must obtain from the Ministry of Foreign Affairs the permit for the bank to establish the trust. This takes 2–4 additional weeks and is handled entirely by the notary.
Stage 4: Deed Signing
All parties must be physically present or represented by a notarized power of attorney. If you can't be in Mexico, you can grant an apostilled power of attorney in your home country for a representative to sign on your behalf.
Payments at signing: remaining purchase price balance, ISAI (~3%), notary fees (~1–1.5%), registry rights (~0.5%), fideicomiso setup costs.
Stage 5: Registry Registration
After signing, the notary files the deed at the Public Property Registry. This takes 2–6 weeks. Once registered, you are the legal owner and the deed is delivered to you.
