Power of attorney for Mexico from Phoenix: Mexican consulate, or Arizona notary and apostille?

From Phoenix you can sign a power of attorney for Mexico in two ways: at the Consulate General of Mexico in Phoenix, whose page says the power leaves with no apostille and takes effect in Mexico, or before an Arizona notary public, and then the document needs the Arizona Secretary of State’s apostille ($3) and, in Mexico, whatever translation and protocolización the receiving office asks for.

Before you book, ask whoever will use the power in Mexico (the fedatario público, the bank or the agency) which route they accept and what the text has to say. Didi, our Spanish-speaking notary public in Phoenix, comes in only on the second route.

What Mexican matters does a power signed from Phoenix cover?

The ones you can’t handle in person: selling or buying a house, land or a car, collecting an inheritance or a life-insurance payout, or moving a bank account. Those are the matters the Consulate General of Mexico in Phoenix itself lists on its powers page (read October 22, 2026).

Mexico’s Federal Civil Code separates general powers (lawsuits and collections, administering property, and acts of ownership) from special powers (arts. 2553 and 2554). A general power is granted in a public deed or in a carta poder signed before two witnesses with the signatures ratified before a fedatario, a judge or the administrative authority (art. 2555); without that form it’s void (art. 2557).

Which one you need, and with which faculties, is for the fedatario or attorney in Mexico who will use the document to decide. Didi can’t draft it or suggest the wording (A.R.S. § 41-273(A)).

If you were looking for a carta poder so your child can travel, that document is a permission, not a power: see our guide to the travel consent letter for Mexico.

Route 1: How do you sign the power at the Mexican Consulate in Phoenix?

By appointment, at the consulate at 320 East McDowell Road, Suite 320, Phoenix, AZ 85004, where the consul attests the act. Mexican law lets the heads of consular offices attest acts signed abroad that will take effect in Mexico (Ley del Servicio Exterior Mexicano, art. 44, section IV) and attest, authenticate, protocolize and revoke powers inside their district (regulations, art. 87). Phoenix’s covers Maricopa, Apache, Coconino, Gila, Mohave, Navajo and Yavapai counties (consulate’s contact page).

The consulate explains that its acts are granted only when they will take effect in Mexico and that they “no requieren de legalización, apostilla o protocolización alguna para surtir efectos jurídicos inmediatos en nuestro país”: no legalization, apostille or protocolización is needed for them to take immediate legal effect in Mexico (powers page, last updated May 15, 2026). That squares with the Apostille Convention, which doesn’t apply to documents of diplomatic or consular agents (art. 1).

What does the consulate ask for?

You book through Mi Consulado or by WhatsApp at +1 (424) 309-0009. The consulate asks for the completed application; your ID (a Mexican one such as your passport or matrícula consular, or a U.S. one such as a green card or driver license if the name is identical to the one on your birth certificate); your birth certificate, plus your marriage certificate if you’re married; a photo of your agent’s ID in Mexico; and the facts of the matter (the deed, the car’s factura or a bank statement, as the case may be). The consulate drafts the power from that information and may ask for more documents. It does not ratify signatures on a document drafted elsewhere; for that, its page suggests granting a power at the consulate.

What does a power at the consulate cost?

A power granted by an individual costs $177.00 USD, and $264.00 USD when a company grants it (the consulate’s fee table). The national schedule, the extract of the Ley Federal de Derechos for 2026 posted by the consulate in Yuma, says the same in dollars: “Por los mandatos o poderes, así como la revocación de los mismos: a). Generales o especiales otorgados por personas físicas 177.00”. Hours: Monday to Friday, 7:30 a.m. to 5:00 p.m.; phone (602) 242-7398.

Route 2: How do you sign before an Arizona notary public, and what comes next?

You bring the power already drafted by the fedatario or attorney in Mexico, complete and unsigned, and sign it in front of Didi. An Arizona notary public can’t draft legal records or give legal advice (A.R.S. § 41-273(A)).

You sign in person (A.R.S. § 41-254(A)) with a current ID Arizona law accepts, such as a U.S. passport or a state driver license or ID card (§ 41-255), or a matrícula consular issued with biometric verification (§ 41-5001). Because it’s a power of attorney, you put your right thumbprint in Didi’s notary journal, since September 12, 2026 (§ 41-254(C)); our parental power of attorney guide explains why the notary takes your thumbprint.

Your conversation with Didi can be in Spanish (§ 41-253(F)), and the power itself can be written in Spanish. What follows doesn’t run through our office: the apostille, and whatever the office in Mexico asks for.

Notice required by Arizona law (A.R.S. § 41-273)

I am not an attorney licensed to practice law in this state. I am not allowed to draft legal records, give advice on legal matters, including immigration, or charge a fee for those activities.

No soy abogada con licencia para ejercer la abogacía en este estado. No estoy autorizada para redactar documentos legales, dar asesoría sobre asuntos legales, incluyendo inmigración, ni cobrar por esas actividades.

Didilia De La O, Notary Public, Arizona

How do you get the apostille in Phoenix, and what does it cost?

From the Arizona Secretary of State, for $3 per document. The apostille certifies the Arizona notary public’s signature and seal for a Hague Convention country (A.R.S. § 41-325); the United States has been a party since October 15, 1981, and Mexico since August 14, 1995 (HCCH status table). Neither Didi nor any notary public can apostille anything.

By mail you send the original notarized power, the Apostille/Certificate of Authentication Request form, the payment and a prepaid return envelope, to Secretary of State, Attn: Apostille Dept., 1700 W. Washington Street, Fl. 7, Phoenix, AZ 85007-2808; it takes 10 to 20 business days. In person, with a $25 expedite fee and a six-document limit; from November 2, 2026, the Phoenix office serves by online appointment only and you get the location when the appointment is confirmed (it no longer serves the public at 1700 W. Washington Street); phone 602-542-6187. A child’s travel consent letter for Mexico follows the same route when an apostille is asked for.

What will they ask for in Mexico with a power signed in Arizona?

A Spanish translation of whatever is in English and, depending on the case, protocolización before a fedatario. The office receiving the power decides; nobody in the United States can promise you otherwise.

The apostille’s ten fields are in English by statute (A.R.S. § 41-326), and the notary public’s certificate is usually in English too. Mexican consulates say documents issued abroad arrive apostilled and, when they’re in another language, with a Spanish translation (Consulate of Mexico in Tucson). So the order is sign, apostille, then translate. We do the certified Spanish translation, but ask before you order it: some governments ask for a sworn translator or a perito authorized in that state.

And the protocolización?

Mexico and the United States are both parties to the 1940 Washington Protocol on powers of attorney used abroad (the United States ratified it in 1942 and Mexico in 1953). Its Article VII says a power granted in another country doesn’t need registration or protocolización as a prerequisite, except where the law requires it as a special formality in specific cases; Mexico’s Federal Civil Code calls for a public instrument or ratified signatures for a general power (art. 2555). Whether yours must be protocolized, and what that costs there, is for the fedatario in Mexico to tell you.

How do the two routes compare?

The two routes, with what each one asks for and costs, and what Mexico still decides:

Route	Where you sign and who attests	Apostille	Spanish translation	Protocolización in Mexico	Public cost	Source
1. Power at the consulate	At the Consulate General of Mexico in Phoenix; the consul, with fe pública valid throughout Mexico	No: the Convention doesn’t apply to documents of consular agents, and the consulate says its acts need none	Not needed: the consulate drafts the power (if you don’t speak Spanish, they require an interpreter)	No, per the consulate	$177.00 USD for an individual; $264.00 USD for a company	Ley del Servicio Exterior Mexicano, art. 44; its regulations, arts. 87 and 88; Apostille Convention, art. 1; consulate’s powers page
2. Arizona notary public + apostille	Before an Arizona notary public, in person, with ID and your thumbprint in the journal	Yes: Arizona Secretary of State, $3 per document	Yes, of the notary public’s certificate and the apostille, when the office asks	The receiving office decides (1940 Protocol, art. VII; Federal Civil Code, art. 2555)	Up to $10 per notary public signature, plus the $3 apostille, plus the translation (we confirm the price with you)	A.R.S. §§ 41-254, 41-255, 41-325 and 41-326; A.A.C. R2-12-1102; azsos.gov; 1940 Protocol; Federal Civil Code

Table sources: Ley del Servicio Exterior Mexicano, art. 44, and its regulations, arts. 87 and 88; Apostille Convention, art. 1; the consulate’s powers page (October 22, 2026); A.R.S. §§ 41-254, 41-255, 41-325 and 41-326; A.A.C. R2-12-1102; azsos.gov; 1940 Protocol, art. VII; Código Civil Federal, arts. 2551 to 2557.

Which route should you choose?

It depends on the appointment you can get and on what the receiving office accepts. At the consulate one office handles it, the power comes out in Spanish with no apostille, and you pay $177.00 USD; the date depends on what Mi Consulado has open. With the notary public you sign when it suits you and the upfront cost is lower (up to $10 per signature plus the $3 apostille), but the apostille takes 10 to 20 business days by mail (or in person, by appointment from November 2, 2026, with the $25 fee), then comes the translation and, if they ask for it, the protocolización in Mexico. If the fedatario told you “bring it from the consulate,” that’s your route. If they said “notarized and apostilled,” it’s the second.

Get your power notarized with Didi in Phoenix, and translate what’s needed

At Puente Grande, Didi notarizes in person in Phoenix, in English or Spanish. Bring the power they sent you from Mexico and your ID. Arizona’s rules cap the fee at $10 per notary public signature (A.A.C. R2-12-1102, in the Secretary of State’s manual, pp. 24 and 53), and we tell you the total before the appointment. Tell us the power is for Mexico; you request the apostille yourself from the Secretary of State and, when it comes back, we translate the certificate and the apostille into Spanish (we confirm that price with you first).

Message us on WhatsApp at (602) 332-9460 with a photo of the document, how many people will sign, and “it’s for Mexico.” Prefer to talk? Call us, or use our contact form. We reply to most inquiries within 1 hour during business hours. Read other families’ testimonials, and see what else we notarize on our notary public services page.

What this guide does not answer

This guide doesn’t tell you which power to grant, which faculties to include, how it should be worded, whether it’s valid in Mexico, or what tax effects it has there. An attorney in Mexico or the fedatario who will use the document answers those. This article is for information only and is not legal advice. If the power touches your immigration case, talk to an immigration attorney or an accredited representative of an organization recognized by the Department of Justice; EOIR, the Department of Justice office that includes the immigration courts, publishes the roster of recognized organizations and accredited representatives.
