So, I am writing this book and I have a little problem and need some help. It is about a woman who takes care of her ex-girlfriend's daughter. They got together before the baby was born, the father signed away his rights before the baby was born. My question is if the girl could have been put on the birth certificate as the other parent since the father signed away his rights (in some states they actually allow two parents of the same gender on the birth certificate) or if they would have to go through step-parent adoption. Also, the bio mom comes back years later after leaving when her daughter was still a baby and wants to be in her life again. I want to make some drama so she is going to fight for custody. Could she have a good chance of getting it just because she's the biological parent? Thanks in advance for all your answers! P. S. Couldn't find answer to this anywhere on the internet!
