In parentage cases, also called “paternity cases,” the court makes orders that say who the child’s legal parents are.
If parents are married when a child is born, there is usually no question about parentage. The law assumes that the husband is the father and the wife is the mother, so paternity is automatically established in most cases.
But for unmarried parents, parentage of their children needs to be established legally. So even if a father can prove he is the biological father of a child, if he was never married to the mother, he does not legally have any rights or responsibilities for the child.
If a person is established as a legal parent of a child, that person MUST financially support the child. It is a crime for a legal parent to fail to support his or her child. A legal parent also has the right to get custody or visitation rights related to the child.
