Mexico: New Law Now Requires Adults Traveling With Children to Prove Their Relationship at Hotels and Tourist Services

A new federal law that took effect in Mexico on Saturday, November 14, 2026, requires hotels and other tourism businesses to confirm that any adult traveling with a child is that child’s parent, legal guardian or custodian before providing service. That includes parents traveling with their own kids.

President Claudia Sheinbaum signed the decree on November 10, and it was published in Mexico’s official gazette, the Diario Oficial de la Federación, on November 13. It took effect the next day. Congress passed the reform unanimously: the Chamber of Deputies approved it in April 2025 and the Senate voted 104–0 on October 7.

What the law says

The decree adds two new sections, X Bis and X Ter, to Article 58 of Mexico’s General Tourism Law, the article that lists the obligations of tourism service providers. Under the new rules:

• Before providing service, in person or through online booking, tourism providers must ask tourists who are accompanied by minors to prove their kinship, parental authority, guardianship or custody of the children with official documents.
• Where it applies, adults may also be asked to prove with official documents that a companion is of legal age (18 or older).
• If the relationship cannot be proven, the provider must refuse service and notify investigating authorities of a possible crime.
• Providers must also follow child-protection protocols that the authorities will define.

The law applies to tourism service providers nationwide. Mexican media reports describe that as covering hotels, motels and vacation rentals, along with tourist transportation, restaurants and bars, spas and entertainment venues. The reform’s stated purpose is to fight child trafficking and the sexual exploitation of minors in tourism.

What is not settled yet

The decree does not say which documents count as proof. Mexican authorities have not yet published a list of accepted documents or the detailed protocols providers must follow. Until they do, requirements may vary from one hotel, resort, rental or tour company to another.

This law is separate from Mexico’s immigration and entry rules for minors, which have not changed.

What travelers should do now

Until official guidance is issued, travel advisors and family-travel specialists suggest that adults traveling to Mexico with anyone under 18 carry:

• A valid passport for every traveler.
• A birth certificate for each child that lists the parents’ names (a long-form or full copy, not a short abstract).
• Custody, guardianship or adoption papers, if they apply.
• A notarized consent letter from the parents if the child is traveling with grandparents, other relatives, friends or any adult who is not a parent or legal guardian.
• A consent letter from the other parent if only one parent is traveling, plus extra proof (such as a marriage certificate or name-change document) if a parent and child have different last names.

Before you go, contact your hotel, rental host and any tour operators and ask:

1. Which documents do you require for minors under the new law?
2. Do you accept copies or digital versions, or do you need originals?
3. Do any documents need to be translated into Spanish?

Get the answers in writing if you can, and don’t wait until check-in. This applies to anyone heading to Mexico with children over Thanksgiving or the Christmas holidays.
