Power of attorney from the U.S. or Canada for property and estates in Mexico

How to grant a power of attorney from the U.S. or Canada to sell, buy or manage property in Mexico, or for an estate: signing before a local notary, apostille, perito translation and protocolización before a Mexican notario.

Why a power of attorney made outside Mexico takes several steps

If you live in the United States or Canada and own a home in Mexico, want to buy or sell property, or are an heir in an estate, sooner or later someone will have to sign on your behalf before a Mexican notario público. For that you need a power of attorney the notary's office can accept.

An important detail: a U.S. or Canadian notary public is not the same as a Mexican notario. There, the notary usually just checks your identity and signature. In Mexico, the notario is a lawyer with a broad public role who drafts the document, reviews the legality of the act and records it in their protocol. That is why a power signed abroad needs extra steps before it takes effect in Mexico.

Before you sign: decide which kind of power you need

In Mexico, powers of attorney are broadly classified as powers for litigation and collections (pleitos y cobranzas), for acts of administration and for acts of ownership (actos de dominio: selling, buying, mortgaging or donating). They can be general or special, limited to one property or one procedure.

Selling a property almost always requires a power with ownership authority that clearly describes the property. In an estate, the power usually authorizes the representative to appear in the notarial or court proceedings, accept the inheritance or the role of executor, and sign whatever is needed.

Our main advice: before you sign anything, ask the Mexican notary's office handling the transaction for a draft of the power or the list of powers it needs. Powers are often rejected not because of the apostille or the translation, but because they lack an authority the notary or the public registry considers essential.

Route 1: sign in the United States or Canada

1. Sign before a local notary

You sign the power before a notary public (in the U.S.) or before a notary or authorized lawyer (in Canada). Ideally the document is bilingual, or in Spanish with an English version, based on the Mexican notary's draft. Bring official ID and, if you are married, ask whether your spouse must sign too.

2. Apostille in the state or province

The power is apostilled in the state or province where it was signed. In the U.S. it is apostilled by that state's Secretary of State: see, for example, Texas, Arizona, California, Florida, Colorado or Washington. State apostilles take 5 to 7 business days on average (California and Florida usually 3 to 5; New York and New Jersey 12 to 15).

In Canada, if you signed in Ontario, Quebec, British Columbia, Alberta or Saskatchewan, that province apostilles it; elsewhere, Global Affairs Canada does. More on U.S. powers of attorney and Canadian powers of attorney.

Remember: a U.S. or Canadian document cannot be apostilled in Mexico. Thanks to the Hague Convention (Mexico since 1995, the United States since 1981 and Canada since 11 January 2024), no consular legalization is needed once the apostille is on.

3. Perito translation

If the power is not entirely in Spanish, the notary will ask for a translation by a perito traductor that includes the apostille. Even with a bilingual power, some notaries ask for the apostille and the foreign notary's certificate to be translated. Confirm which peritos the notary accepts.

4. Protocolización before a Mexican notario

Finally, the Mexican notario carries out the protocolización of the power: they incorporate it into their protocol so it can be used in deeds and, where applicable, recorded at the Public Property Registry. Without this step, many property transactions cannot be formalized.

Route 2: if you are in Mexico, sign before a Mexican notario

If you are in Mexico, even on a visit, the most direct option is usually to grant the power before a Mexican notario público. That avoids the apostille, the translation and the later protocolización, because the power is born in a Mexican notary's protocol. You will need a valid passport, proof of your legal stay in the country and, if the notary asks, other details such as an RFC or CURP.

If you are not coming to Mexico, you can also ask at the nearest Mexican consulate, since consulates have notarial functions for certain powers of attorney. Appointment availability and requirements vary by consulate.
