Filiation Law and Legal Definition
Filiation is the judicial determination of paternity. It is the fact or condition of being a son or daughter. The law has established a legal presumption to serve as a foundation for paternity and filiation. When the mother is or has been married, her husband is presumed to be the father of children born during coverture, or within a competent time afterwards, whether they were conceived during the coverture or not. This presumption may, however, be rebutted by showing either that there has been no cohabitation, or some physical or other impossibility that the husband could be the father.
