My daughter has her fathers last name not mine. we were only seventeen when we had her and of course we thought we would be together forever. Now he isn't in the picture. We live on the other side of the United States from him and he doesnt do anything to help me. He calls and asks to talk to her daughter but, she is only one so doesn't really know how to work a phone yet. Anyways... I would really like her to have my last name but, I'm not really sure how to do it. I don't know if I need his consent? O is their any way I could do it with out his consent? Has anyone had this problem before?
