Natural children are those conceived out of wedlock.
The 1936 law divides recognition certificates into 3 categories
1 Children born out of wedlock are those whose father and mother were able to contract a marriage together at the time they were conceived.
2 Adulterine children are those whose father and mother, or one of them, were married to other people at the time of conception.
3 Incestuous children are those whose father and mother are related or allied to a degree that prohibits marriage between them.
In the latter case, see : Art 335, Civil Code: Recognition cannot be given to children born of an incestuous or adulterous relationship.
The recognition of a child born out of wedlock will be made by an authenticated deed (1), if it has not been made in the child's birth certificate.
Acknowledgement will be made at the time of the birth declaration or acknowledgement will be made after the birth.
The deed will be entered in the registers on the date, if any.
