I'm a mother a 3 1/2 yr old boy. Whose "father" is more of a sperm donor than a father. He has never been involved and I would rather it stay that way. Hes been in trouble with the law, and is always disappearing for long periods. I'm currently seeing a man I am going to marry in the future. I want to know what I have to do so he can adopt my son. My sons sperm donor is not on the birth cert. So I'm unsure what his rights are. Any help would be nice. Thank you.
