532. A child whose filiation is not established by an act and by possession of status consistent therewith may claim his filiation before the court. Similarly, the father or the mother may claim paternity or maternity of a child whose filiation in their regard is not established by an act and by possession of status consistent therewith.
If the child already has another filiation established by an act of birth, by the possession of status, or by the effect of a presumption of paternity, an action to claim status may not be brought unless it is joined to an action contesting the status thus established.
The action for disavowal or for contestation of status is directed against the child and against the mother or the presumed father, as the case may be.
