Somebody in the Ensenada Expats Facebook group asked last month what happens to their house when they die. A pretty reasonable question for people who own property in a foreign country. The answers were a mix of partially correct instincts, confident misinformation, and at least one person suggesting their US will would “just cover it.”

It won’t.

Your US will has no authority over Mexican real property. A Mexican judge cannot be compelled to honor it. Getting it recognized here requires apostille, sworn translation, a full court proceeding, and a minimum of six months — usually more. That’s on a good day. And even then, it still can’t retitle land. Mexican courts have exclusive jurisdiction over Mexican real estate, period.

The good news is that if you own in the restricted zone — within 50 km of the coast, which covers most of Baja California — you almost certainly already own your property through a fideicomiso, and that fideicomiso already has its own inheritance mechanism that’s faster and cheaper than any will. The less good news is that most people never update it after they set it up, and a lot of people have no Mexican will at all, and a shocking number of people have no beneficiary designations on their Mexican bank accounts.

The result is predictable. The “Latino family fighting over property” stereotype exists because it describes something that actually happens, over and over, to people who just never got around to the paperwork.

TL;DR

  • Your US will cannot directly transfer Mexican property. Don't rely on it for anything south of the border.
  • Your fideicomiso controls your restricted-zone property — not your will. Update the substitute beneficiary list there first.
  • Bank accounts with designated beneficiaries pass outside your will and outside probate. Do this at your bank now.
  • A Mexican testamento público abierto covers everything else: vehicles, personal property, direct-title real estate, accounts without beneficiaries. It costs about $85–90 USD in September (Baja California) and less than $500 any other time of year.
  • Dying intestate (without a will) in Mexico is a one-to-three-year court process that can consume 15–25% of your estate. If no heirs qualify, the state takes it.
  • Three documents. In this order: fideicomiso beneficiaries, bank account beneficiaries, Mexican will.

The Notario Público Is Not a Notary

Before anything else: stop confusing the Mexican Notario Público with a US notary public. They are not the same thing. At all.

A US notary public is a person who watches you sign something and stamps it. They can’t give legal advice. They charge $15. They mean very little.

A Mexican Notario Público is a licensed attorney who passed a rigorous state examination and was appointed for life by the state governor. Their number is capped by population — roughly one per 30,000 residents. In all of Baja California there are 84: 45 in Tijuana, 22 in Mexicali, 11 in Ensenada, 3 in Tecate, 2 in Rosarito, 1 in San Quintín. They wield what Mexican law calls fe pública — their authentication of a document carries the evidentiary weight of a court judgment. They are the only people legally permitted to draft and execute wills, transfer real estate, and record property deeds.

For real estate closings, Notarios charge roughly 1–2% of property value. For a will, outside of September, the cost runs about $3,000–$10,000 MXN — roughly $150–$500 USD. Inside Baja California during September, it drops to $1,500 MXN + IVA. Call it $85–90 USD for a document that can save your heirs a year of court proceedings and 15–25% of your estate value.

That is the most efficient money you’ll spend in Mexico.

The Theatrical Performance: How a Mexican Will Actually Works

Here’s what the process looks like, because it is genuinely theatrical in a way that will confuse anyone used to the US system.

You make an appointment at a Notaría. You bring your documents. The Notario — a licensed attorney — drafts your will based on your instructions. Then they read it aloud to you. The entire thing. Out loud. In Spanish. Under Article 1519 of the Código Civil Federal, this must occur in a single continuous act. You confirm it reflects your wishes, you and the Notario both sign the protocol, and the original stays in the notarial archive forever.

The entire thing costs under $500 USD and takes one appointment. The US equivalent takes 15 minutes and $15. That’s the gap.

The reason most Mexicans don’t do it isn’t the cost. It’s the word. “Testamento” is culturally associated with summoning death — se llama a la muerte.

Four point seven percent. That’s the will-making rate among the general Mexican population. The resulting property disputes are not a stereotype. They’re a statistical certainty.

As gringos in a foreign legal system, we don’t have the luxury of procrastination. We’re already starting from disadvantage — foreign nationals, unfamiliar bureaucracy, assets in a jurisdiction where our home-country documents carry no direct legal weight. The state bureaucrats who extract 20% of an estate from poor planning don’t care that you had a perfectly valid Arizona will. They’ll process the sucesión intestamentaria at whatever pace they feel like, and take their cut along the way.

This is the thing that surprises most people. Your Mexican estate isn’t governed by one system. It’s governed by three parallel, independent systems, and a document in one has no authority over the others.

Asset Type What Controls It Does Your Will Override? Probate Required?
Restricted-zone real estate (fideicomiso) Fideicomiso trust deed — substitute beneficiary clause No No
Bank accounts with designated beneficiaries Bank beneficiary form (Art. 56, Ley de Instituciones de Crédito) No No
Vehicles, personal property, jewelry, art Mexican will (testamento) Yes — this is what a will covers Yes
Bank accounts without beneficiaries Mexican will or intestate succession Yes Yes
Direct-title real estate (if you naturalized) Mexican will or intestate succession Yes Yes

MexLaw’s estate team puts it plainly: “Property held through a Bank Trust is not included or referred to in a Will made in Mexico.” The trust deed governs the property. Period.

Your Fideicomiso Is Already Your Estate Plan (Sort Of)

If you own in Baja’s restricted zone — within 50 km of the coast or 100 km of the border — Mexican law required you to buy through a fideicomiso. That’s the bank trust structure established under Articles 11–14 of the Ley de Inversión Extranjera, which allows a Mexican bank to hold legal title as fiduciary while you, as fideicomisario, enjoy full rights to use, lease, improve, sell, or bequeath the property.

Common trustee banks: Citibanamex, Scotiabank Inverlat, BBVA, Santander, HSBC, Banorte, Banco del Bajío, Banco Monex.

The trust deed names you as primary beneficiary and should also name one or more fideicomisarios sustitutos — substitute beneficiaries. On your death, the substitute produces an apostilled death certificate, the trustee bank obtains a fresh SRE permit, a new appraisal is performed (which also establishes a stepped-up cost basis for the heir), and title transfers. Usually in weeks. No court, no probate judge, no edictos, no sucesión.

The fideicomiso was set up correctly. The problem is that life happens and nobody updates it. You named your ex-spouse. You named your parent who died two years ago. You named your adult child who you’re currently not speaking to. The beneficiary list in the trust deed is a legal document, not a preference you can override with a post-it note.

Updating it costs money. Both the trustee bank and a Notario are involved. Budget roughly $3,000 USD all-in for a full formal amendment — bank administrative fees run $300–$700, plus notarial ratification, any apostilles and translations needed for foreign documents, and Public Registry re-filing. Where the bank allows a simpler instruction-letter amendment, it can run $500–$1,500. Either way, be certain about your beneficiaries before you set it up, and revisit it after any major life change.

⚠️ After a divorce

Update your fideicomiso substitute beneficiaries immediately. An ex-spouse named in the trust deed gets the property. Your will cannot override it.

⚠️ After a death in the family

If a named substitute beneficiary predeceases you and you haven't updated the deed, their share may fall to the secondary substitute — or into intestate succession. Check the trust.

⚠️ After naturalization

Mexican citizens can hold coastal property directly, but most estate attorneys advise keeping the fideicomiso anyway. It keeps property out of probate regardless of how your heirs' citizenship shakes out.

✓ Foreign heirs are fine

A foreign national can inherit through a fideicomiso substitute clause — they just step into your position as the new fideicomisario. No special permit required beyond the standard SRE process.

Why You Should Keep the Fideicomiso Even After Naturalization

This one surprises people. If you gain Mexican nationality, you’re legally allowed to terminate the trust and take direct title to coastal property. Most cross-border estate attorneys say: don’t.

The fideicomiso works like a US revocable living trust. It keeps property out of probate entirely. The substitute beneficiary transfer closes in weeks. A foreign spouse, adult children, or grandchildren with complicated citizenship situations face no obstacles. The annual fee — $500–$800 USD — is cheap insurance against a sucesión that could run a year or more and consume 3–7% of estate value even in the uncontested track.

Bank Accounts: The Fastest Win in Mexican Estate Planning

Under Article 56 of Mexico’s Ley de Instituciones de Crédito — reformed in 2009 — bank account holders can designate beneficiaries who receive the entire balance on proof of death, bypassing both the will and probate entirely. The beneficiary presents an apostilled death certificate and their ID at the bank, and the funds are released. No court order. No albacea. No edictos.

One catch: if an account has no beneficiary designation and the balance exceeds roughly MXN $70,000 (the threshold varies by bank — Citibanamex uses MXN $190,000), the bank freezes the account on receipt of the death certificate and won’t release funds until a formal sucesión is opened with an albacea appointed and sworn in. That’s a one-to-two-year process to access a checking account.

Go to your bank this week. Designate beneficiaries on every account. This is free. It takes 20 minutes. It saves your heirs a year of paperwork.

What Happens If You Die Without Any of This: The Intestate Path

Here’s the scenario nobody wants to discuss but everyone should understand.

You die in Ensenada. No Mexican will. Your fideicomiso names your ex-spouse because you never updated it. Your bank accounts have no beneficiary designations. Your kids are American. Your car is parked outside.

The fideicomiso? Your ex-spouse gets the house. That’s the law.

The bank accounts? Frozen until probate opens. A judge has to appoint an albacea before anyone can touch them.

The car, the furniture, the personal property? Intestate succession under the Código Civil de Baja California kicks in. The order: descendants, surviving spouse, ascendants, collateral relatives to the fourth degree. Your adult American children would eventually inherit — but the process takes one to three years in uncontested cases, longer with any dispute.

The attorney fees for a contested intestate judicial proceeding run MXN $20,000–$100,000, or 10–30% of estate value. Add notary transfer fees, appraisals, newspaper notices (edictos — legally required publication in two widely-circulated state dailies for a 40-working-day claim period), court costs, and the ISABI property transfer tax. The aggregate is routinely 15–25% of estate value. That’s your family’s inheritance paying for the machinery of a court system that exists because you didn’t spend $150 on a will.

If there are no qualifying heirs at all — no descendants, no spouse, no ascendants, no relatives within four degrees of consanguinity — the estate passes to Mexico’s Beneficencia Pública. The state takes it. Restricted-zone land the state can’t constitutionally hold gets sold at public auction, proceeds going to Beneficencia Pública. Your property. Auctioned. Because you procrastinated.

Even if you have no heirs and genuinely want to donate everything to charity: write the will. Name the charity. A Mexican testamento gives your donation legal standing. Without it, the Civil Code’s defaults govern, and a bureaucratic institution takes a cut of whatever makes it through.

The Baja California Inheritance Tax Advantage

One piece of genuinely good news: ISABI — the property transfer tax — is 0% for direct-line inheritance in Baja California. Spouse to spouse. Parent to child. Fully exempt under Ley de Hacienda Municipal del Estado de BC, Article 75-Bis B. The general 2% rate applies to anyone else — grandchildren, siblings, nieces/nephews, unrelated heirs. Mexico has no federal estate or inheritance tax, and inheritance income is exempt from ISR for Mexican tax residents under Article 93 of the Ley del ISR.

Your US Will: What It Can and Cannot Do Here

Your US will is not useless. It governs your US assets perfectly well — retirement accounts, US bank accounts, US real estate, your car back in the States.

For Mexican assets, it’s a starting point that requires significant legal processing before a Mexican court will recognize it.

The practitioner consensus is to run two wills in parallel. Your US will for US assets, your Mexican testamento for Mexican assets, with explicit non-revocation language in each document so they don’t accidentally cancel each other out. A competent estate attorney in either country can draft that cross-referencing language.

September Is the Time to Do This in Baja

Every September, the Colegio Nacional del Notariado Mexicano and the Secretaría de Gobernación run Septiembre, Mes del Testamento — a campaign that’s been running since 2003 and slashes notario fees by up to 50% nationwide.

In Baja California, the pricing is aggressive: the Colegio de Notarios de Baja California set the 2025 campaign rate at $1,500 MXN + IVA — roughly $85–90 USD. Baja California is the second-cheapest state in Mexico for this (after Veracruz). The campaign typically extends through October for seniors. The official government portal is gob.mx/testamento.

During the September campaign, monthly will volume in Mexico nationally jumps from roughly 10,000–15,000 to 70,000. Get ahead of that line.

The Three-Document Checklist

1️⃣ Fideicomiso substitute beneficiaries

Pull out your trust deed. Who is named as fideicomisario sustituto? Is that still the right person? If not, contact your trustee bank and a Notario. Budget $500–$3,000 USD for the update. Do this first — it covers your largest asset.

2️⃣ Bank account beneficiary designations

Visit every Mexican bank where you hold an account. Designate beneficiaries on each one. This is free and takes minutes at the branch or through your app. It completely bypasses probate — no cap, no court.

3️⃣ Mexican testamento público abierto

Schedule an appointment at a local Notaría. In September, pay $1,500 MXN. Any other month, pay $3,000–$10,000 MXN. Bring your passport, residency card, property escrituras, fideicomiso contract, and beneficiary details. Covers vehicles, personal property, anything the other two don't.

4️⃣ Keep your US will current too

Your US will governs US assets. Update it with explicit language saying it doesn't revoke your Mexican testamento and is limited to US-situated assets. Same cross-reference in the Mexican will limiting it to Mexican assets.

⚠️ After any major life change

Divorce, death of a named beneficiary, new child, estrangement, new property purchase, naturalization — revisit all three documents. The fideicomiso in particular doesn't update itself and a named ex-spouse is a legally binding designation.

🚫 Don't wait for "perfect timing"

People die without wills every week because they were going to get around to it. The September discount is nice. But $400 in October is infinitely better than nothing in March. Do it when you can, not when it's optimal.

What It Actually Costs to Do Nothing

The math here is uncomfortable but straightforward.

Scenario Upfront cost Estimated estate cost on death Timeline for heirs
Fideicomiso + bank beneficiaries + Mexican will $1,500–$4,000 USD all-in ~3–5% of estate Weeks to a few months
Mexican will only (no fid update, no bank beneficiaries) $150–$500 USD 5–10% of estate 2–6 months
Nothing — intestate, uncontested $0 10–15% of estate 1–2 years
Nothing — intestate, contested or complex $0 15–25% of estate 2–5 years
Estimated costs and timelines by estate planning scenario. Percentages are practitioner estimates and vary by estate complexity. Sources: MexLaw [5], Intestados.mx [6], Settlement Company [4], Maldonado Myers LLP [7].

On a $300,000 property, the difference between doing this right and doing nothing is roughly $30,000–$75,000 going to lawyers, court costs, and state bureaucrats instead of your heirs. On a $600,000 property, double that.

The gringo tax has many forms. This is one of the most avoidable ones.
