Naming of the non-marital child

If the child's mother has sole custody, the child is given the mother's surname by law. If the child is to be given the father's surname, a name assignment is required, which is recorded at the registry office. This requires the consent of both parents.

If the child's parents have joint custody, a name determination is required for the first joint child. This then also applies to any further joint children.

Naming and name determination are also possible before birth.
