In some states, the presumption of paternity is considered conclusive, which means it cannot be disproven, even with contradictory blood tests. A presumed father must pay child support. Courts apply this concept when a spouse and child have a close relationship and consider themselves parent and child or where the biological parent encouraged this relationship. If the court grants an equitable parent custody or visitation, then the parent will also be required to pay child support. An unmarried man who impregnates a woman is referred to as an unwed father.
Unwed fathers have few rights concerning their children.
For example, an unwed father does not have the right to require the mother of the child to obtain his consent, or even notify him, before she undergoes an abortion. A stepfather is not obligated to support the children of the woman to whom he is married unless he legally adopts the children. I want the father of my child to pay child support. A court suit filed to have a man declared the father of a child is called a paternity action. It can be brought by either the mother or the father.
