Power of Attorney to Buy Property Remotely in Mexico

Many foreigners and Mexicans living abroad want to close on a house or condo without flying to Mexico for the signing. The usual solution is a power of attorney (poder notarial) to buy a home, which authorizes a trusted person, or a legal representative, to sign the deed (escritura) on your behalf before the notary public (notario público). This document must be granted with the right scope, drafted with specific powers for acts of ownership (actos de dominio), and, if it is signed outside Mexico, go through an apostille or consular legalization before it is valid before the Mexican notary. Below we review what type of power of attorney to request, who can receive it, and the most common mistakes that delay a closing.

What a power of attorney is and what it is for

A power of attorney (poder notarial) is a public instrument through which one person, the principal (poderdante), authorizes another, the agent (apoderado), to carry out legal acts on their behalf. To buy a property, the power of attorney must include powers for acts of ownership (actos de dominio), meaning the authority to acquire property, sign deeds, accept loan terms if applicable, and appear before a notary. A generic power of attorney is not enough: the notary who closes the transaction will check that the powers granted cover exactly what is going to be signed, including amounts, form of payment and, where applicable, the creation of a trust (fideicomiso) if the buyer is a foreigner and the property is in a restricted zone. An incomplete or poorly drafted power of attorney can force you to repeat the process from your home country, which delays the closing by weeks and can put the deposit you have already paid at risk.

How to get one if you are outside Mexico

The most common way to grant the power of attorney from abroad is to appear before a notary public in your country of residence or before the corresponding Mexican consulate. Each route has its own timelines and requirements, so it is wise to plan several weeks ahead of the signing date scheduled in Mexico.

• Have the power of attorney drafted by a Mexican attorney or by the notary who will handle the deed, to make sure the powers match the transaction
• Sign it before a local notary or at the Mexican consulate in your city of residence
• If it is signed before a foreign notary, obtain the apostille in countries party to the Hague Convention, or consular legalization otherwise
• Have the document translated into Spanish by a certified translator if the original is in another language
• Send the apostilled or legalized original to the Mexican notary for formalization (protocolización)
• Confirm with your agent the exact identification details they will use at the signing

Who you should grant the power to

The agent can be a trusted family member, a Mexican attorney who specializes in real estate, or the real estate advisor who is accompanying the transaction, although in the latter case you should look into possible conflicts of interest. What matters most is that the person understands the agreed terms, is available on the signing date, and can appear before the notary with valid official identification. Many buyers opt for a law firm that offers this representation service as part of its support through the purchase, which reduces the risk of errors in the power of attorney and streamlines coordination with the notary.

Frequently asked questions

Can I use any power of attorney I already have?

Not always. The notary will check that the powers expressly include acts of ownership (actos de dominio) and, if necessary, the creation of a trust (fideicomiso). If the power of attorney is generic or was granted for another purpose, you will probably have to grant a new one specific to this purchase.

How long does it take to get the power of attorney from abroad?

It depends on the country and on whether it requires an apostille or consular legalization; it can take anywhere from a few days to several weeks. That is why you should start the process as soon as the signing date is agreed with the notary in Mexico.

Does the power of attorney have an expiration date?

It can be granted with indefinite validity or limited to a set period or to the specific transaction. To prevent unwanted later use, many buyers prefer to expressly limit it to the purchase in question.
