Apostille or Embassy Legalisation: What Mexico Requires

Last reviewed: 26 September 2026. Country requirements change. This page is re-checked periodically, and nothing on it replaces confirming the position with the Mexican office that will receive your document.

For Mexico the authentication answer is short: an apostille. The translation is where people go wrong. Mexican civil registries commonly want the Spanish translation made by a perito traductor, a translator authorised by the superior court of the Mexican state concerned, and each Mexican state runs its own civil registry with its own list. A translation made in Australia, however good, may not be the one they accept.

Check the current position before acting on this or any other page. Convention membership is a live fact. Confirm Mexico's status against the HCCH status table for the Apostille Convention on the day you start. Mexico has been a party since 1995, so an apostille is the expected route for documents within the Convention's scope.

The usual chain

1. Notarise in Australia, if the document is a private one (a power of attorney, an affidavit, a notarised copy)
2. DFAT apostille
3. Spanish translation, usually made in Mexico by a translator the receiving office recognises

Australian public documents such as birth, marriage and death certificates may be able to go to DFAT directly without a notary. Confirm with DFAT before lodging. For the most common Mexican use — registering an Australian birth or marriage in Mexico — the certificate is a registry document, and a notary may not be needed at all.

Registering an Australian birth or marriage in Mexico

Mexican families in Australia often need to record an Australian birth, marriage, divorce or death in Mexico, for example so a child born here can be recognised as Mexican. Mexican state civil registries call this the registration (inscripción) of a civil record made abroad.

The published requirements of one Mexican state, Nayarit, show the typical shape:

• The foreign certificate must be apostilled. For an Australian certificate, that is DFAT's apostille.
• A Spanish translation by a perito, a translator authorised by that state's superior court of justice (Tribunal Superior de Justicia).
• For a birth, the Mexican parent's own birth certificate, official identification and certified CURP (the Mexican population registry number).
• Originals and a set of copies.

Other states set their own lists and fees, and some may accept a translator authorised elsewhere in Mexico. Ask the civil registry office where you will register, in the Mexican state concerned, for its current list before you order anything.

A Mexican consulate may also be able to register some events for Mexican nationals living abroad. Whether that suits your situation, and what it asks for, is a question for the Mexican mission in Australia.

Translation: do it after the apostille, and usually in Mexico

Two consequences follow from the perito requirement:

• An Australian NAATI translation may not be accepted. It is a professional translation, but it is not made by a translator authorised by a Mexican court. Ask the receiving office before paying for one.
• The apostille usually needs translating too. DFAT's apostille is in English. Ask whether the office wants it translated. If it does, the translation has to be made after the apostille, which is another reason to translate in Mexico once the document arrives.

If you are not travelling, a relative or a representative in Mexico can usually take the apostilled original to a perito there.

Powers of attorney and property

Mexican property, inheritance and company matters are handled through a Mexican notario público, a legally trained official whose role is far wider than an Australian notary's. If you are signing a power of attorney in Australia:

• Get the wording from the Mexican side first, in Spanish or bilingual. A power of attorney that does not give the specific powers Mexican law or the notario requires will be refused however well it is authenticated.
• Ask what happens after the apostille. Ask the notario whether the document must be translated by a perito and formally recorded before them before it can be used.
• If you are a Mexican national, ask about the consular route. Ask the Mexican mission whether it can prepare the power of attorney for you, and ask the notario which route they prefer.
• If you do not read Spanish, tell the Australian notary in advance. They must be satisfied you understand what you are signing and may ask for a translation.

Australians in Mexico

If you are already in Mexico and need an Australian document apostilled or a signature witnessed for use in Australia, the Australian Embassy in Mexico City offers notarial services. It says honorary consulates do not provide notarial services; only the embassy does. For marriage in Mexico it issues a Certificate of No Impediment, applied for in person at the embassy.

Frequently asked questions

Does the Mexican embassy need to legalise my Australian document? Not for a document within the Convention's scope. The apostille replaces embassy legalisation.

Can I use one translation for several Mexican states? Do not assume so. Each state's civil registry sets its own rules, and some insist on a translator authorised in that state.

How long does it take? It depends on DFAT processing, the translator and the Mexican office. Do not plan to a figure quoted on a blog, including this one.
