I live in Virginia. My daughter is 19 months old. She has her father's last name on her SSC but he wasn't at the hospital to sign the birth certificate so I didn't get one there. She still doesn't have one. We have no legal custody agreement but I take care of her and pay for her. He takes her one night a week if its at his convenience but I send her with everything she needs. I want to move out of state (to Florida most likely) and I want to know what would happen if I do so. I'd also like to change her last name.
