Yes, you generally need a notarized consent letter (often called a “Letter of Permission” or “Travel Consent Letter”) when traveling to Mexico with a minor child if you are not both parents/legal guardians.
While Mexican law does not explicitly require it for entry, Mexican immigration officials (INM) and airlines frequently ask for it to prevent international child abduction. Being unprepared can lead to significant delays, denial of boarding, or entry refusal.
Key Requirements for the Consent Letter:
- Notarization: The letter must be notarized. A simple signed letter is often not sufficient.
- From the Non-Traveling Parent(s)/Guardian: It should be signed by all non-accompanying parents or legal guardians. If one parent has sole custody, you should carry proof (court order, death certificate, etc.).
- Details Included:
- Child’s full name, date of birth, passport number, and place of issue.
- Accompanying parent’s/guardian’s full name, relationship, and passport details.
- Non-accompanying parent’s/guardian’s full name, contact information, and signature.
- Travel details: Destination(s) in Mexico, travel dates, flight information.
- Purpose of the trip.
- Statement of permission for the child to travel.
Strongly Recommended Additional Documents:
- Proof of Relationship: Carry the child’s original birth certificate (with parent’s names) or a certified copy.
- Custody Documents: If applicable, bring any court orders regarding custody or guardianship.
- Passports: All travelers
