A French minor crossing a border must present their own identity documents. Traveling with a child requires gathering administrative papers that vary depending on the destination, mode of transport, and the composition of the accompanying group. In some cases, an identity card is sufficient, while a passport becomes mandatory in others, and specific authorizations are added when a parent is absent from the trip.
Child’s identity card or passport: what the destination country requires
The fundamental distinction lies in the geographical area. Within the European Union and the Schengen area, a valid national identity card is sufficient for a minor, regardless of their age. The document must be in the child’s name: registration on a parent’s passport is no longer legally valid.

For any destination outside the European Union, an individual passport is required. Some countries require that this passport remains valid for several months after the expected return date. Checking this residual validity before booking a ticket avoids a boarding denial on the day of departure.
Beyond the passport, several countries require a visa or an electronic travel authorization (AVE, ETA according to local terms). Canada, for example, requires an AVE for any traveler arriving by air, including children. Finding travel permits for minors on Concept Voyages allows you to verify the specific requirements for each destination before preparing the file.

Exit authorization: the Cerfa form not to forget

The exit authorization (AST) concerns any minor residing in France who leaves the country without being accompanied by at least one of their parents. The system relies on the dedicated Cerfa form, signed by a holder of parental authority.
This form alone is not sufficient. It must be accompanied by a copy of the identity document of the signing parent. Without these two elements combined, border police may refuse the exit from the territory, even if the child has a valid passport.
A often overlooked point: the AST does not replace the passport or identity card. It is an additional requirement. A minor traveling with both parents does not need this authorization, but as soon as only one parent accompanies the child to certain destinations, complications may arise.
Traveling with only one parent: additional documents required abroad
Traveling alone with your child may seem straightforward on paper, but several countries require proof of consent from the other parent. A detailed letter of consent, written by the absent parent, is recommended by the authorities of many destinations.
This letter should generally mention:
- The full identity of the child and both parents
- The exact dates and destination of the trip
- The contact details of the non-accompanying parent and the address of the place of stay
- The signature of the parent authorizing the travel
Some countries go further and require a notarized certification of this letter. The cost and time to obtain it vary, but failing to anticipate this formality can block entry into the destination territory.
In cases of sole custody, a court judgment or official proof of sole parental authority may be required. Carrying a copy of the family record book and the child’s birth certificate remains a useful precaution, even when no text formally imposes it.
Travel documents for children by plane: airline requirements
Airlines apply their own rules, sometimes stricter than those of the destination country. A child traveling alone (in UM service, for “unaccompanied minor”) must present a complete file that generally includes the AST, a valid identity document, and a specific form from the airline.

When the child’s last name differs from that of the accompanying adult, proof of the parent-child relationship facilitates checks. A family record book, a birth certificate, or an adoption judgment can clarify the situation unambiguously at the check-in counter.
Keeping digital copies of all documents on a phone or in online storage serves as a safety net. In case of loss or theft of the originals during the trip, these copies expedite the procedures with the consulate.
Travel insurance and health record: often forgotten documents
The administrative aspect is not limited to identity papers. For travel outside the European Union, travel insurance covering the child’s medical expenses avoids considerable costs in case of hospitalization abroad.
Within the European Union, the European Health Insurance Card (EHIC) allows for coverage of medical care. It can be requested free of charge and must be obtained for each family member, including children. The issuance time can take several weeks.
The child’s health record, although not a border document, remains useful in case of medical consultation abroad. Some destinations also impose mandatory vaccinations whose proof must be included in an international vaccination booklet.
Preparing documentation for a trip with a minor takes time, especially when the destination requires a visa or notarized certification. Starting the procedures at least six weeks before departure allows enough time to obtain passports, authorizations, and insurance without last-minute rush.
