Hi all, just after some help for a mate of mine. He has full custody of his daughter and has had since she was approx 8 months old. The daughter will be turning 7 in a few months and hasn't seen her mother in the last 5 and a half years. The father wants to change the child's last name as it is hyphonated with both parents last name to only his last name. He has tried contacting the child's mother but she refuses to allow the name change to happen. What's the next step he should take?
