My fiancé wants to adopt my daughter, but her bio father is on the because
First of all I know there have been a lot of questions like mine posted already but please bare with me anyway. Any help will be greatly appreciated. Thanks.
I am engaged to a wonderful man and we've discussed him legally adopting my 18month daughter, and her getting his last name. She has her biological fathers name now and yes he is listed on the birth cert. we were never married. She sees him every other weekend now, but we've not gone to court to establish visitation we've just done it ourselves so far, he also doesn't pay support because we've not involved the court. Does her bio father have to give up all rights in order for my fiancé to adopt her (once were married of course) and can her bio father stop us from changing her last name? We plan on getting married by the end of the year so it would be easier to adjust if the name was changed while she's still young, before school and everything.
Again any help is appreciated and I greatly thank you.
