Apostilles and translations for a Mexican notary (US and Canada)

By Lic. Pati Claudia Galarza, attorney (Licenciada en Derecho), Cédula Profesional 15176510 · Published October 18, 2026 · Español

A US or Canadian public document, such as a birth or marriage certificate, a divorce decree or a notarized power of attorney, is accepted by a Mexican notario público when it carries an apostille from the authority that issued it and is translated into Spanish by an authorized translator. Mexico, the United States and Canada are all parties to the Hague Apostille Convention, so no consular legalization is needed. A power of attorney can also be signed at a Mexican consulate, which avoids the apostille.

The Apostille Convention

The Hague Convention of 5 October 1961 Abolishing the Requirement of Legalisation for Foreign Public Documents replaces the old chain of certifications with a single certificate, the apostille. According to the HCCH status table, the Convention entered into force for Mexico on 14 August 1995, for the United States on 15 October 1981 and for Canada on 11 January 2024 (Canada acceded on 12 May 2023). Before 2024, Canadian documents needed legalization by a Mexican consulate; for documents with an apostille, that step is no longer needed.

Under articles 3 and 5 of the Convention, the apostille certifies the authenticity of the signature, the capacity of the person who signed and the seal or stamp on the document. It does not certify that the content is correct. The Convention covers public documents: court documents, administrative documents such as vital records, notarial acts, and official certificates placed on private documents, such as a notary's acknowledgment of a signature. It does not apply to documents executed by diplomatic or consular agents (article 1).

Who issues apostilles in the United States

Documents issued by a US state, such as birth, marriage and death certificates, need an apostille from that state's secretary of state. Federal documents need an apostille from the US Department of State. The apostille comes from the state that issued the document, not the state where you live: a birth certificate from Ohio is apostilled in Ohio even if you live in Arizona.

Who issues apostilles in Canada

According to Global Affairs Canada, the authority depends on where the document was issued or notarized:

Alberta, British Columbia, Ontario, Quebec and Saskatchewan have their own competent authorities for documents issued or notarized in those provinces.
Global Affairs Canada handles documents issued by the Government of Canada and documents issued or notarized in Manitoba, New Brunswick, Newfoundland and Labrador, Nova Scotia, Prince Edward Island, the Northwest Territories, Nunavut and Yukon.
In British Columbia and Quebec, the provincial authority can apostille a notarized document only if the original document was also issued in that province. Global Affairs Canada offers an online triage tool to find the right office.

Canadian apostilles are issued as an allonge, a separate sheet securely attached to the document. Do not remove it.

Documents that usually need an apostille

Birth certificates, for example for a fideicomiso, a succession or proof of identity of an heir.
Marriage certificates, when the buyer's or seller's marital status matters to the sale.
Divorce decrees and death certificates, to show that a former spouse or a deceased owner no longer needs to sign. Ask the notary early whether your decree can be used as it is for your transaction.
Corporate documents of a US or Canadian company: certificate of good standing, articles and resolutions appointing a representative.
Powers of attorney signed abroad before a foreign notary.

Translation by an authorized perito traductor

Article 113 of the Ley del Notariado para el Estado de Baja California says that documents in a foreign language may be added to the notary's records when they are translated by an interpreter authorized by the Tribunal Superior de Justicia del Estado. Each year the Poder Judicial del Estado publishes in the Boletín Judicial the official list of peritos, which includes English translators. The list in force for 2026 was published on 12 December 2025 and has English translators registered in Playas de Rosarito, San Felipe, Tijuana, Ensenada, Mexicali, Tecate and San Quintín. The new Ley Orgánica del Poder Judicial del Estado (published 31 August 2026) keeps the annual list in its article 128.

Ask the translator to translate the whole document, including the apostille and any stamps. Because article 113 refers to an authorized interpreter, a translation made in the US or Canada by someone who is not on the Baja California list may not meet it; check with the notary before paying for one.

Separately, article 127 of the Ley del Notariado says that a party who does not speak Spanish attends the signing with an interpreter of their choosing, who formally promises before the notary to interpret faithfully.

Powers of attorney: Mexican consulate or foreign notary

If you cannot travel to sign, there are two ways to grant a power of attorney from abroad.

At a Mexican consulate. Under article 44, fraction IV, of the Ley del Servicio Exterior Mexicano, heads of consular offices exercise notarial functions for acts signed abroad that are to be carried out in Mexico, with the same legal force throughout Mexico as acts of a notary of Mexico City. Because the Convention does not apply to documents executed by consular agents, no apostille is involved. Ask the consulate about appointments and language.
Before a US or Canadian notary, followed by an apostille and a translation. Under article 113 of the Ley del Notariado de Baja California, powers granted outside Mexico, once legalized or apostilled, must be protocolized (recorded by a Baja California notary) to take effect, subject to the exceptions in the law and international agreements.

Either way, have the text drafted or reviewed in Mexico before you sign. A foreign-style form often lacks the wording Mexican law and the notary need for the specific act, such as selling a property or signing a fideicomiso. Irrevocable powers for acts of administration or ownership are always reported by the notary to Hacienda under the federal anti-money-laundering law.

Timing and practical tips

Order fresh certified copies first. The apostille is placed on the certified copy issued by the authority, not on a photocopy.
Then get the apostille, then the translation, so the translation covers the apostille.
Ask the notary in advance which documents they need, whether they want a recently issued certified copy, and whether they accept scans for review before the originals arrive.
Check processing times on each authority's website and allow for mailing time. Start several weeks before the signing date.
Names must match across your passport, certificates and contract. Fix discrepancies before the signing, not at it.

Frequently asked questions

Does Mexico accept apostilles from Canada?

Yes. The Apostille Convention entered into force for Canada on 11 January 2024, and Mexico has been a party since 1995. A Canadian document with an apostille no longer needs legalization at a Mexican consulate.

Can my US translator translate my documents?

For a Baja California notary, the translation should be made by a translator authorized by the state judiciary (Ley del Notariado de Baja California, art. 113). The Poder Judicial publishes the list of authorized peritos every year.

Does a power of attorney signed at a Mexican consulate need an apostille?

No. The Apostille Convention does not apply to documents executed by consular agents, and consular notarial acts have the same force in Mexico as those of a Mexico City notary (Ley del Servicio Exterior Mexicano, art. 44, fr. IV).

Where do I apostille a birth certificate if I moved to another state?

In the state that issued it. In the US, state vital records are apostilled by that state's secretary of state; in Canada, it depends on the province of issue, as explained by Global Affairs Canada.
