What is a Legal Representative in Mexico?

A Mexican company acts through its legal representative. This person signs contracts, deals with the SAT and banks, and represents the company before the authorities. Here is what the role involves in 2026.
1. What does it mean to be a legal representative?
The legal representative is the individual authorized to act on the company’s behalf. The company’s sole administrator or general manager usually holds this role, and additional representatives can be appointed through powers of attorney.
2. Who can represent a company?
Mexican law sets no nationality requirement, so a foreigner can be the legal representative. In practice the representative needs:
- A personal RFC and an e.firma, obtained in person at the SAT
- An immigration status that allows the activity, if they are a foreigner in Mexico
- Availability to sign documents and attend bank and SAT appointments
For these reasons, many foreign-owned companies appoint a representative who lives in Mexico.
3. What powers does a representative need?
Powers are granted in the deed of incorporation or in a notarized power of attorney. The usual ones are powers for lawsuits and collections, acts of administration, acts of ownership and the signing of negotiable instruments. Powers can be limited, for example by requiring two signatures for large payments.
4. What are the functions of a legal representative?
- Signing contracts and corporate documents
- Handling the company’s RFC, e.firma and tax filings with the SAT
- Opening and operating the corporate bank account
- Registering the company with the IMSS and other authorities
- Receiving official notices
5. Responsibilities
The representative can be jointly liable for certain unpaid taxes if the company fails to comply, for example when it is not located at its tax address. Choose someone you trust and define the powers carefully.
