Article 32

If the father of the child has a second patronymic, the child will also have a second patronymic, unless the parents of the child, on the occasion of the declaration of birth, jointly make a choice for a family name. If the father of the child has a family name, the child will also have this family name, unless the parents of the child, on the occasion of the declaration of birth, jointly make a choice for a second patronymic.

Where no legal filiation link between child and father has been established, the child shall have a first name, the patronymic of his mother and the second patronymic of his mother or a family name. If the mother of the child has a second patronymic, the child will also have a second patronymic, unless the mother, on the occasion of the declaration of birth, makes a choice for a family name. If the mother of the child has a family name, the child will also have this family name, unless the mother, on the occasion of the declaration of birth, makes a choice for a second patronymic.

If a legal filiation link between child and father is established after the birth of the child, the patronymic and the second patronymic or family name of the child will change in accordance with sub-Article (1). A choice for a family name or for a second patronymic may be made before any civil status officer within a period of six months after the establishment of the legal filiation link. If the child has not reached the age of majority, this choice may be made by the parents of the child jointly. If the child has reached the age of majority, the child himself may make this choice.

All the common children of parents, or, where no legal filiation link between children and father has been established, all children of the mother shall have the same patronymic or family name.
