“Paternity” means fatherhood. In the legal sense, “establishing paternity” refers to the determination of a child’s “legal” father and the related rights and obligations of the father to the child. Every child has a biological father, but not every child has a “legal” father. When “paternity has been established” it means that someone has been named the legal father of a child.
Paternity is automatically established if the parents are married to each other when the child is born. The husband is the legal father and his name will be on the child’s birth certificate. In Texas, if the parents of a child are not married to each other when the child is born, the child has no legal father until paternity is established. Once paternity is established, the father’s name will be placed on the child’s birth certificate and the father will gain certain rights to the child.
