My mother just had a baby and the father was not present when he was suppose to sign the birth certificate and he did not sign the BC. he visits my baby sister but he does not give child support or help out in anyway and has not made anything legal in terms of sign any legal documentaton stating hes the biological father. My mother and i were wanting to move not out of state we wanted to stay in Texas but just move south but he threated my mother he would get a lawyer and take legal action can he do that? Does he even have that much authority even if he didnt even recognize my sister?
