Property Due Diligence in Mexico

We verify the property at the source — never the seller's folder

Every property story in Mexico has two versions: the one in the seller's folder, and the one in the public registries. They usually match. When they don't, the difference is your savings. Our due diligence works exclusively from the source: the Public Registry of Property, the National Agrarian Registry (RAN), municipal records, and the documents we pull ourselves — because sellers' folders can be… creative.

The seven verifications

• Title and ownership history — the folio real and its full chain at the Public Registry of Property, not just the last transfer.
• Seller identity and capacity — is the person selling actually the registered owner? Married under community property (a spouse may need to sign)? A company with valid powers of attorney? An heir whose probate actually finished?
• Ejido / agrarian status — the check that decides everything (see below). Our signature, cross-checked at the RAN.
• Liens, mortgages and lawsuits — a fresh certificado de libertad de gravamen, issued days before closing, not months.
• Debts that travel with the property — unpaid predial, water bills and HOA fees follow the property, meaning they can follow you. If it's a condo, we read the regime rules too — some prohibit the rentals you're planning.
• Water rights — if the property depends on a well or surface water, the concession title at the national water registry: whose name, what use, when it expires. After the December 2025 reform, water no longer "follows the land" — and the 2026 regularization window makes this check urgent for rural property.
• Land use — municipal and federal layers — the uso de suelo classification against what you actually plan to do there; and on coastal property, the ZOFEMAT concession for anything sitting on the federal strip. Perfectly titled land can still be unusable for your project.

The ejido check most buyers skip

Roughly half of Mexico is ejido or communal land — and it sits exactly where foreigners love to buy. That land lives in a different registry (the RAN), follows a different law, and while it remains under the ejido regime, a foreigner cannot acquire ownership of it — whatever the paperwork says. What circulates around it is possession, often priced as ownership.

This is our specialty and the reason clients come to us: we cross-check every property against the agrarian system — parcel certificates, dominio pleno history, whether a "converted" property really completed its conversion, and whether any corner of the land touches common-use land, where the largest frauds happen. If you want to see what skipping this check looks like, read our analysis of the Bacalar case — 130 families who paid for lots that never legally existed. Or start lighter: take the 2-minute ejido test.

What you receive

A written risk report in plain English: what the property is, what it isn't, every red flag we found, and a clear recommendation — proceed, renegotiate, or walk away. If the deal is good, you close with confidence. If it isn't, the report just paid for itself many times over.

When you need it — and when you don't

You need it before signing anything that moves money — including the contrato de promesa and its deposit, which is where most buyers get bound before they ever call a lawyer. You don't need the full package for a presale from a large, bank-financed developer with published title insurance — there, a lighter contract review may be enough, and we'll tell you so. Our advice doesn't change whether you buy or walk away — that independence is the product.

One more thing the closing table won't tell you: the notario doesn't do this for you. The notario formalizes the deal; they don't investigate the seller or hunt for agrarian problems. That's your lawyer's job — ours.

How legal fees actually work in Mexico — and how we quote

Mexico doesn't leave professional fees to improvisation. Notarial fees are tariffed: each state publishes an official fee schedule (arancel) for its notaries, so the notary's charges in your closing are set by act and value — you can sanity-check any notarial quote against the published schedule. Attorney fees work differently: statutory fee schedules exist as a legal reference (courts use them, for example, to compute court-awarded costs), but in practice attorney fees are set by agreement. That's why we quote a flat fee, in writing, before we start — the certainty the arancel system was designed to give, in a single number. No percentages, no surprises, no incentive to see the deal close. And one warning: a "cheap" quote that ignores tariffed notarial and registry costs isn't saving them — it's hiding them.
