For an adult

You want to give a common name to your child? The name used in everyday life is different from surname. We tell you the rules to know about the username (who chooses it, which name to choose?) and how to include this name on the child's identity papers.

Every person has a surname.

For example, it may be the name of the father or the mother.

However, it is possible to in everyday life another name, called common name.

The last name may change over the course of life.

The last name does not replace the last name which remains the only name mentioned on the civil status documents.

The parent(s) holding the exercise of parental authority choose the minor child's username

Parental authority exercised jointly by the two parents

Choice by 2 parents

Parents together choose the name of their minor child.

If the child has over 13 years, his agreement is necessary.

Parents are advised to formalize in writing their agreement.

In case of disagreement, you must enter the Family Court Judge (Jaf).

Choice by parent who did not pass name to child

The parent can add his or her name, as a usage name, to the name of the minor child, without the consent of the other parent.

The parent must inform other parent before the child uses that last name.

Indeed, the other parent must have time to indicate disagreement, or if he so wishes, to refer the matter to the Judge for Family Affairs (Jaf).

It is recommended to keep evidence that the other parent has been informed in advance.

The disagreement of the other parent and the referral to the Jaf do not prevent the parent from adding his or her name, as a usage name, to that of the minor child.

In all cases, whether the parents agree among themselves or not, the child over 13 years of age must give his consent.

If the minor over 13 years of age does not agree, he cannot bear a common name.
