Full text
542.19. No one may claim filiation contrary to that assigned by their act of birth and the uninterrupted possession of status consistent with that act.
Unless otherwise provided by law, no one may contest the status of a person whose uninterrupted possession of status is consistent with their act of birth.
Where uninterrupted possession of status cannot be established because it is exercised by more than one person simultaneously, the person who is biologically related to the child takes precedence. However, in the case of a child born of procreation involving the contribution of a third person, the person who formed a parental project with the child’s parent takes precedence.
