Mexican Wills for Foreign Property Owners in Mexico

Your foreign will may not protect what you own in Mexico

A U.S. or Canadian will is not automatically effective over Mexican assets. It can eventually be recognized — through a cross-border probate process involving apostilles, certified translations and Mexican courts that routinely takes years, while your property sits in limbo and your heirs pay lawyers on both sides of the border. A Mexican will covering your Mexican assets avoids nearly all of it.

What happens without a Mexican will

Your estate enters Mexican intestate succession (sucesión intestada) or foreign-will recognition — both court processes. The Civil Code decides who inherits and in what order, not you; your heirs must prove their kinship with apostilled, officially translated documents from abroad; and the proceeding runs before Mexican courts with patience measured in years, not months. Meanwhile: the property can't be sold, the bank account is frozen in practice, and the predial and maintenance keep accruing. Every estate is unique — but the pattern isn't: the cost of that process is many multiples of the cost of the will that would have prevented it.

Who needs one

Owners of a house or land held in direct title
Beneficiaries of a fideicomiso (yes, even you — see below)
Shareholders or partners in a Mexican company
Holders of Mexican bank or investment accounts

How a Mexican will works alongside your estate plan back home

The two documents coexist by scope: your Mexican will covers your Mexican assets; your home-country plan covers everything else. Drafted correctly, neither revokes the other — and that drafting detail is precisely where do-it-yourself wills fail, because a standard "I revoke all prior wills" clause in either document can accidentally destroy the other. We coordinate the language so each instrument stays in its lane.

Fideicomiso beneficiary designations — the detail most people get wrong

Your fideicomiso lets you name substitute beneficiaries who receive your rights on death without probate — the single most powerful estate-planning feature foreigners own in Mexico, and the one most leave blank or outdated. Common failures: naming a spouse who died first and never updating; naming minors with no structure; assuming the designation covers assets outside the trust (it doesn't — that's what the will is for). We review the designation and the will together, as one plan.

Signing before a notario — we prepare everything and accompany you; interpreters are arranged where the law requires them.
The will is registered in the national registry of wills. Your heirs will be able to find it.

What it costs — and why September is special

A Mexican will has two cost components, and both are unusually transparent. The notarial fee is tariffed: each state publishes an official fee schedule (arancel) for its notaries, so the notary's charge for a will is set by schedule, not improvised. And every September — Mexico's "Month of the Will" (Mes del Testamento) — that tariffed fee drops substantially nationwide as part of a public campaign to get wills done. Our own fee for the design, drafting and coordination is a flat fee, in writing, before we start. Together, a properly built Mexican will costs a small fraction of one month of the cross-border probate it prevents.

Frequently asked questions

Do I have to be a resident to make a Mexican will?

No. Any foreigner with assets in Mexico can execute a Mexican will — tourists included. What matters is owning something in Mexico worth protecting.

Does a Mexican will affect my assets outside Mexico?

Drafted correctly, no: it is expressly limited to assets located in Mexico, and its revocation clause is scoped so it never touches your home-country plan.

What is the Month of the Will (Mes del Testamento)?

Every September, notario fees for wills drop substantially nationwide as part of a public campaign. It's a real discount and a fine deadline to finally do this — but if your purchase closes in March, don't wait.

How much does a Mexican will cost?

Two transparent components: the notario's fee, which is tariffed by each state's official fee schedule (arancel) — and drops substantially every September during the Month of the Will — plus our flat fee for design, drafting and coordination, quoted in writing before we start. The total is a small fraction of the cross-border probate it prevents.

What happens if I die without any will in Mexico?

Your Mexican assets enter intestate succession: the Civil Code decides who inherits and in what order — not you. Your heirs must prove kinship with apostilled, translated documents before a Mexican court, in a process measured in years, while the property can't be sold and the accounts freeze in practice. Every estate is unique, but that pattern is nearly universal — and entirely preventable.

September is Mexico's Month of the Will — but any month works
