Mexico (MX)
Mexico is one of the world's most important expat destinations, especially for US and Canadian retirees, remote workers, entrepreneurs, families and lifestyle migrants.
Estate & Inheritance in Mexico
Wills, intestacy, inheritance tax, and cross-border estate planning for expats.
Mexico estate planning is state-based, notary-heavy and cross-border-sensitive. Foreign residents should not rely only on a home-country will if they own Mexican property, have Mexican bank accounts, a fideicomiso, Mexican spouse/children, domestic partnership issues or business interests. The best 2026 plan usually coordinates a Mexican will, home-country will, trust/fideicomiso beneficiaries, tax advice, medical powers, funeral preferences and emergency document access.
Intestacy — What Happens Without a Will
If someone dies without a valid will, succession follows the relevant Mexican state civil code and court/notary process. Spouse, children, parents and other relatives may have rights depending family structure and property regime. Cross-border heirs face extra translation, apostille/legalisation and representation steps.
Types of Valid Will
Public open will
Testamento publico abiertoThe most common formal Mexican will, made before a notary. It is usually the preferred format for foreign residents with Mexican assets.
Valid when executed with required formalities before a notary.
Use a bilingual lawyer/notary process if Spanish is not strong. Coordinate with foreign wills so they do not revoke each other accidentally.
Special or emergency wills
Testamentos especialesCertain emergency or special-context wills may exist under state law, but they are not ideal for expat planning.
Highly fact-specific and formal.
Do not rely on emergency formats for ordinary planning.
Foreign will used in Mexico
Testamento extranjeroA foreign will may be recognised only after legalisation/apostille, translation and Mexican legal process.
Depends on home-country validity and Mexican recognition process.
Usually slower than having a Mexico-specific will for Mexican assets.
Forced Heirship
Mexico does not operate exactly like one single national forced-heirship system. State civil codes, marital property regime, maintenance obligations and family claims can affect outcomes. Get state-specific advice if you have spouse, children from prior relationships, dependants or blended-family issues.
EU Succession Regulation (Brussels IV)
EU Succession Regulation does not govern Mexican assets directly. EU nationals with Mexican property should coordinate EU habitual-residence/electio juris planning with Mexican wills and local property rules.
Inheritance Tax
Mexico does not have a broad federal inheritance tax like some countries, but tax, notary, registry, capital gains basis and foreign tax consequences still matter. Heirs may face costs, filings and home-country reporting.
| Relationship | Tax-Free Allowance | Tax Rate (above allowance) |
|---|---|---|
| Spouse/children/parents | No simple national allowance model | No broad federal inheritance tax; local/notary and foreign tax issues may apply |
| Other relatives | Depends on transaction and jurisdiction | Seek tax advice before transfer or sale |
| Unrelated beneficiaries | No standard allowance; documents and taxes need review | Potential income/capital-gains and foreign-tax consequences |
Tax treatment can differ between inheritance, gift, sale and trust-beneficiary transfer. Keep acquisition cost and improvement invoices because later sale tax can be affected.
Cross-Border & Multi-Country Estates
Cross-border estates need passport, death certificate, marriage/birth certificates, apostilles, certified translations, tax IDs, bank forms and sometimes powers of attorney. Heirs abroad may need Mexican consulate notarisation or local counsel. US, Canadian and European citizens should coordinate home estate tax/reporting with Mexican process.
Certificate of Inheritance
Succession may proceed through notary or court depending whether there is a will, heirs agree, minors are involved and state rules. Documents must be translated/legalised where foreign. Banks and fideicomiso trustees have their own claim requirements.
Will Registration
Wills executed before Mexican notaries are recorded through notarial/state/national will systems. Tell trusted heirs which notary handled the will and keep a copy accessible, even though the official instrument remains in notarial protocol.
Living Will & Healthcare Power of Attorney
Advance healthcare directives and powers of attorney are state-specific. Foreign residents should prepare medical authorisations, emergency contacts, insurance authority and powers of attorney in Spanish with local advice. Keep these documents accessible to a trusted person in Mexico, not only in a home-country safe.
