Don’t have time to go to an institution or company to handle certain tasks? A power of attorney letter for procedures might be the legal solution you’re looking for. The problem is, many don’t know how to write it or when witnesses or a notary are required.
But in this short guide, you’ll learn everything you need to draft a power of attorney letter for procedures in Mexico. We’ll also share an example and free downloadable templates so you can personalize your own.
It’s a written document through which you formally authorize another person to handle a procedure on your behalf. This may be before a public or private institution to, for example, submit documents, make payments, or complete administrative processes.
It’s used when the authority or institution allows it and it doesn’t involve transferring rights or making major decisions. Therefore, it’s not a power of attorney valid for significant legal actions such as selling property, as those require notarized authorization.
The power of attorney letter for procedures in Mexico is backed by the Federal Civil Code under the following articles:
Article 2551. It explains that a mandate exists when a person authorizes another to legally act on their behalf. It may cover specific or general matters.
Article 2556. Allows granting the power in writing, without a notary or witnesses, but only if the procedure does not exceed 1,000 times the minimum wage. This means the amount must be equal to or less than $278,800 MXN (based on the 2025 daily minimum wage).
It also states that the power may be verbal if the value is very low (up to 50 minimum wages).
In short, you can use a simple power of attorney letter for basic responsibilities.
When cases are more complex or general, the same law requires signing the power of attorney letter before two witnesses and having it ratified—either before a notary public or another competent authority.
Article 2555 of the Federal Civil Code establishes that this formality is required if:
You grant a general power not limited to a single procedure.
The procedure has a value greater than 1,000 times the minimum wage.
The procedure is very important and must be carried out through a public instrument, such as establishing a company or selling assets.
However, it's also important to check local regulations before using a power of attorney letter—especially if the procedure is handled by state or municipal authorities.
Why?
Because each state has its own civil code that sets specific requirements or limits for the validity of a power of attorney letter.
For example, Article 2811 of the Civil Code of Quintana Roo sets a maximum value of $5,000 MXN—a lower threshold than what the Federal Civil Code stipulates.
Here are the power of attorney requirements you absolutely must include:
Place and date. To locate the time and place the power is granted, which gives it context and legal weight.
Full name of the grantor and the representative. Both individuals must be clearly identified.
Identification details. Such as your RFC, CURP, or even your Mexican passport number, depending on the type of procedure.
Purpose of the power. This means clearly stating what procedure or task the authorized person will be allowed to carry out.
Signature of the grantor. To validate the authorization.
Signature of the representative and witnesses (if applicable). Not always mandatory, but some procedures may require it.
Duration or validity. You can specify whether the power of attorney is temporary or valid only for a single task.
This information is useful, but do you want to see what a power of attorney letter for procedures in Mexico looks like? We’ll show you a model so you have a clear idea.
If you’re still unsure how to write a power of attorney letter for procedures, here’s an example that can serve as a guide.
