A foreign company entering Mexico soon discovers that its corporate documents, flawless in its home country, are not enough here. When the notary does not record them, the registry does not register them, or the bank does not open the account, the reason is almost always missing authentication, translation, or notarial recording (protocolización).
What the law requires
Authentication. Under Article 1248 of the Commercial Code (Código de Comercio), in commercial proceedings, foreign public documents must be legalized by Mexican consular authorities to be given full faith, unless they were transmitted through official channels or a treaty with the country of origin exempts them from legalization (Article 1249). The Hague Convention Abolishing the Requirement of Legalization for Foreign Public Documents is that type of treaty: between countries that are parties to it, legalization is replaced by the apostille. The National Code of Civil and Family Procedure (Código Nacional de Procedimientos Civiles y Familiares) recognizes foreign public documents when they are submitted duly apostilled or legalized, and provides that, if legalization cannot be obtained, it may be replaced by other adequate proof of authenticity (Articles 314 and 1144).
Translation. Documents written in a foreign language must be accompanied by a Spanish translation (Article 1055, section II, of the Commercial Code). In civil proceedings, if the opposing party disagrees with the translation, it must submit one by an expert translator within three days, and if the translations differ, the authority orders one from an official expert translator or an educational institution (Article 315 of the National Code of Civil and Family Procedure). That is why it is advisable to submit an expert translation from the outset, which avoids that dispute.
Notarial recording for registration. Documents of foreign origin relating to registrable acts may first be recorded in a public instrument executed before a notary or a commercial notary (corredor público) for registration with the Public Registry of Commerce (Article 26 of the Commercial Code). Acts that must be registered and are not registered only have effect between the parties that entered into them (Article 27).
Powers of attorney. A general power of attorney granted abroad must clearly show whether it confers powers for lawsuits and collections, for acts of administration, or for acts of ownership, because in Mexico those categories have different scopes under Article 2554 of the Federal Civil Code (Código Civil Federal). A power drafted with formulas foreign to that scheme often raises doubts about its scope before notaries, banks, and authorities.
Form and revocation of the power. Under Mexican law, a general mandate must be granted in a public deed or in a private power of attorney letter (carta poder) signed before two witnesses, with the signatures ratified before a notary or an authority (Article 2555 of the Federal Civil Code). A general power of attorney granted abroad must therefore be executed before an authorized attesting officer in its country, authenticated, and translated. When an attorney-in-fact leaves the company, the revocation must be notified to the persons with whom that attorney-in-fact dealt; otherwise, the company remains bound by what that person does afterward (Article 2597).
The new procedural code. The National Code of Civil and Family Procedure enters into force gradually, no later than April 1, 2027, and will apply on a supplementary basis in commercial proceedings under the amendment to the Commercial Code published on November 14, 2025.
What to do and by when
- Make a list of the documents you will need in Mexico: articles of incorporation, current bylaws, certificates of existence, minutes of corporate bodies, and powers of attorney.
- Check whether the country of origin is a party to the apostille convention; if it is, obtain an apostille; if not, process consular legalization.
- Commission Spanish translations from an expert translator, preferably one authorized in the state where they will be used.
- Draft powers of attorney according to the categories of Article 2554 of the Federal Civil Code, with express powers for the acts the attorney-in-fact will perform in Mexico.
- Have the documents that must be registered with the Public Registry of Commerce recorded before a notary or commercial notary.
- Calculate the practical validity period of foreign certificates, because many institutions require them to be recent.
- Keep a file with the apostilled originals, translations, and certified notarial copies.
- When an attorney-in-fact leaves the company, revoke the power and notify the banks, clients, and authorities that person dealt with.
Recommendations to mitigate risk
There is no specific fine for submitting a foreign document without an apostille or without a translation. The risk is that it has no effect: the notary does not record it, the Public Registry of Commerce does not register it, the judge gives it no evidentiary value, and the opposing party can challenge it. A defective power of attorney can leave the company without an authorized representative to sign a contract or appear before an authority at the moment it needs one. In addition, a registrable act that is not registered cannot be asserted against third parties (Article 27 of the Commercial Code).
In a hypothetical scenario, the foreign parent grants a power of attorney in its own language, before an attesting officer in its country, with a generic formula to “represent the company in all its affairs.” In Mexico, the notary cannot determine whether it includes acts of ownership, the bank rejects it for opening the account, and the signing of the first contract is delayed for weeks while a new power is granted.
