The law involving Paternity refers to the idea of who is the ‘legal father’ of a child. The legal father may not necessarily be the biological father. A legal father refers to a man recognized by law as the male parent of a child. A man is considered to be the legal father of a child if he was married to the child’s natural mother when the child was born, if he recognized or legally acknowleged the child or if he has been declared the child’s natural father in a paternity action.
