Paternity cases determine the father of a child when a child is born out of wedlock. When parties are married, the husband is presumed, by law, to be the biological father of a child. When parties are not married, a father can sign an affidavit of parentage. Paternity can also be established by a paternity/DNA test being performed either privately or through the courts. Once paternity is established, it can only be changed by a revocation of paternity action. Call Smith Mihas to find piece of mind and certainty in your paternity concerns.
