Authorization to leave the territory (AST)

Verified 30 October 2026 - Public Service / (Prime Minister)

A minor of French nationality who lives in France (or a minor of foreign nationality who usually lives in France) and who travels abroad must have an exit authorization (AST) if he does not travel with a person who has parental authority. We present you the information to know.

Authorization to leave the country (AST) is mandatory as soon as a minor child leaves France without being accompanied of one of its parents or a other person with parental authority (guardian, curator).

Tableau - Minors concerned or not by AST

Minors concerned

Minors not concerned

  • French minor living in France
  • Minor foreigner who usually lives in France
  • A French minor who lives abroad and stays in France does not need an AST when he leaves France.
  • A foreigners minor living abroad who stays or transits through France does not need an AST.

A child traveling only with his father or only with his mother has no need for AST, even if his parents are separated or divorced.

Please note

If the minor leaves the metropolis to go to a overseas department or region (Drom), it must have an AST in the event of a stopover abroad.

You must fill in a form :

Authorization to leave the country (AST)

Once you have completed the entry, you will be able to download the completed form. You can also print the blank form and fill it out by hand.

Please note

No displacement is not required. It is not necessary to go to the town hall, the prefecture or the police station.

The duration of AST is set by the parent who signs it. It may correspond to the duration of a particular trip or have a longer duration (6 months for example).

However, the period of validity of the AST may not not to exceed 1 year.

The AST form must be presented to the border guard during the border control.

The AST must be signed by a single parent holding parental authority. It is not necessary for the 2 parents to sign the form.

Warning  

If the minor is the subject of a Exit opposition (OST) or a exit ban (IST), he cannot leave French territory, even if he has an AST. The OST prohibits any exit from the territory. In the case of STIs, exit is only possible if the STI is lifted. The lifting must be the subject of a declaration before a judicial police officer (OPJ) by one or other of the parents holding parental authority (rights and duties towards the child) or 2.

Where the parents are divorced or separated, the signature of the AST depends on who exercises parental authority:

  • In case ofjoint parental authority, the AST must be signed by one of the two parents, without the need for the other parent to sign. However, it is recommended to obtain the agreement of the other parent to avoid any conflict.
  • If one parent holds parental authority by court decision (exclusive parental authority), this parent is the only one able to sign the AST.

If the minor travels in l' or abroad alone or without one of his parents, the minor must have AST and a photocopy legible the valid identity card or passport of the person who signed the AST form.

The photocopy of the official document proving the identity of the signatory must include the following elements:

  • His name and first names
  • Date and place of birth
  • His photograph
  • His signature
  • The dates of issue and validity of the document and the issuing authority.

Depending on the nationality of the person signing the AST, different types of identity documents are allowed:

Please note

No other documents shall not be asked of him. For example, the family record book cannot be required when your child crosses the border, even if the child and the parent who signed the AST have a different name.

The AST form is legally sufficient, even if the parent who signed it does not have the same surname as the child. There is no legal requirement to present a family booklet. However, as a precaution, it may be useful to have a copy to avoid any misunderstanding.

It is strongly recommended to consult the section Travel advice on the site diplomatie.gouv.fr:
