When the consent provided for in article 342-10 is obtained, the female couple shall jointly acknowledge the child.
Filiation is established, with regard to the woman giving birth, in accordance with article 311-25. It is established, with regard to the other woman, by the joint acknowledgement provided for in the first paragraph of this article. This is given by one of the two women or, where applicable, by the person responsible for declaring the birth to the civil registrar, who indicates this in the birth certificate.
As long as filiation thus established has not been contested in court under the conditions laid down in the second paragraph of article 342-10, it prevents the establishment of another filiation under the conditions laid down in this title.
