quick background-ex left when i became pg, says he wants nothing to do with either of us and told his family she is not his child(even though he knows full well that she is!) he made threats to burn my house down and we got moved, baby id due in Oct, so he wont be on the birth certificate as we're not married and i know he wont be interested, what do i do about claiming maintenance if he carries on saying hes not the father?
