my husband and I have talked about him adopting my 1 year old daughter.She knows him as "daddy" and he has supported both us since she 4 months old. I do not know where her biological father is, who he is, and he is not on the birth certificate.I was in a relationship with someone when she was born and put BOTH mine and his last name on her certificate due to pressure. but he is not on the certificate and he wasnt there and I never spoke to him after she was born. Can I file for abandonment then my husband could adopt?
