Power of Attorney Signed in the U.S. for Use in Mexico
If you are in the U.S. and need someone to sign for you in Mexico —selling a house, accepting an inheritance or handling a bank matter— the power is signed before a notary there, apostilled in that state and translated here by a perito so the Mexican notario can formalize it (protocolización).
Which Mexican offices ask for this document
These are the most common procedures; the receiving office may ask for more:
Notary Procedures in Mexico: Property, Estates and Companies
- A power of attorney signed in the U.S. or Canada must be signed before a notary there and apostilled in that same state or province.
- Once in Mexico it is translated by a perito, and the notario usually formalizes it (protocolización) before it is used.
- Have the Mexican notario review the wording before you sign, so it includes the powers the transaction needs.
Which version works and which does not
An apostille can only go on a public document with the right signature and seal:
- Signed original with a complete notarial certificate, seal and the notary’s commission expiry
- Copies or scans without the notary’s original seal
- Documents signed in Mexico that appear to have been notarized in the U.S.
How to prepare this document
Follow this order so the authority apostilles it and the Mexican office accepts it:
Draft or review the wording with the Mexican notario who will use it.
Sign before a notary in the U.S. state where you are.
Apostille from that state’s Secretary of State.
Spanish translation by a perito and protocolización before a notario público in Mexico.
Which authority apostilles your document?
The apostille comes from a specific office, depending on where the document was issued or signed. Pick your case:
Secretary of State (State where notarized)
Apostilled by Secretary of State (State where notarized) (Secretary of State of the state where the power was notarized).
Already living in Mexico?
If you are already in Mexico, do not send papers to the U.S. to be notarized: a power for use in Mexico is granted directly before a Mexican notario público and needs no apostille. We help you see which of the two routes fits your case.
1. Online review
Send us a photo or scan of the document. We check the signature, seal and authority before you send anything.
2. Shipping originals
If the procedure needs the original, we tell you how to send it by tracked courier or collect it from your address.
3. Delivery to your door
We send the apostilled document and, if you asked for it, the translation by a perito anywhere in Mexico.
Translation by a perito traductor
Mexican offices usually ask for documents in English or French to be translated into Spanish by a perito traductor authorized by the state judiciary. The translation normally includes the apostille. Each office decides which peritos it accepts: some only take peritos from their own state.
Usual timelines
These are the authorities’ timelines; shipping and translation are on top:
Frequent mistakes and how to avoid them
Signing the power in Mexico and mailing it to the U.S. to be notarized and apostilled.
Incomplete notarial certificates (no county or no commission expiry date).
Powers drafted without the authority the Mexican notario needs for the transaction (for example, acts of ownership).
Apostille questions: Power of Attorney Signed Abroad
Who drafts the power of attorney?
Ideally the Mexican notario who will use it sends you the text or reviews it before you sign in the U.S., so it includes the powers the transaction needs.
Is the whole power translated?
Yes. The perito translation usually covers the power, the U.S. notary’s certificate and the apostille.
I live in Mexico. Can I sign a U.S. power of attorney here and apostille it in the U.S.?
No. A document signed in Mexico cannot be notarized by a U.S. notary or apostilled by a state. If the power will be used in Mexico, the usual route is to grant it before a Mexican notario público, and that document needs no apostille. If it must take effect in the U.S., the route is different and is best reviewed case by case.
