The father and mother exercise parental authority jointly. Parental authority is exercised jointly in the case provided for in article 342-11.
However, where parentage is established with regard to one of them more than one year after the birth of a child whose parentage is already established with regard to the other, the latter remains solely vested with the exercise of parental authority. The same applies when filiation is judicially declared in respect of the child’s second parent or, in the case of establishment of filiation under the conditions set out in Chapter V of Title VII of this Book, when the joint acknowledgement is recorded at the request of the public prosecutor.
Parental authority may nevertheless be exercised jointly in the event of a joint declaration by the father and mother addressed to the director of the judicial registry services of the judicial court or by decision of the family affairs judge.
