Can my daughter be adopted by her stepfather without her biological father's consent?
My daughter has requested to be adopted by her stepfather, my husband, who has been the only real father she has had since my divorce from her biological father when she was 4. We have joint custody, with standard visitation rights for him, but he has not had steady visitation since the first 3 years or so after the divorce, and has only seen her twice in the past 3 years. He has a long record of drug possession and DUIs, and moved out of state a year ago. He is about $50,000 behind in child support for her and her older sister who is now 18. My younger daughter is 16 and will be 17 in June. At this point is it necessary to have her biological father agree to give up his parental rights? If so, can physical and financial abandonment be reason to terminate his rights? When she turns 17 can my daughter choose to terminate the legal relationship? How old can a child be to be able to be adopted? At this late age, would it be better to simply change her name legally, and would her biological father have to agree to that? We want to do what is in her best interest, and after considering this for quite some time, she has decided that she wants my husband to be her legal father and to take his last name.
