Hi, I live in Texas and got married to my husband 4 years ago. I was raising my son on my own and my sin's biologicak father has never financially or emotionally supported my son. He never signed the birth certificate and never even acknowledged his existence. I was wondering if there is anything in Texas fasmily law that would make it easier for my husband to adopt my son. I have no idea where the biological father is or how to get in contact with him regarding signeing away rights he has never used or wanted. I know that he had a daughter with someone else that once he and her mother divorced he signed over rights to her parents without a second thought. I am not afraid he won't sign, I just don't know how easy it will be to find him. Also, how much would it cost for my husband to adopt my son?
