Who the Father Is on Paper

A man is presumed to be a child's father when he and the birth mother are married and the child is born during the marriage, or the child is born within 300 days after the marriage ends by death, annulment, declaration of invalidity or divorce, or after a decree of separation.

• The same is true of an attempted marriage that is or could be declared invalid.
• A man who marries the mother after the birth is presumed the father if he voluntarily asserted parentage and filed it with vital records, is named on the birth certificate with his agreement, or promised in a record to support the child as his own.
• A presumption may be rebutted only as the parentage act provides.
