How can a father who pays child support and whose name is on the birth certificate change the child's last name to his if he and the child's mother were not married?
Answer - In most states, if the parents of a child are not married, then the mother is the sole "legal" parent of the child. Paying child support gives you no legal rights. Ch…ild support is not about anything other than helping to support a child whom you fathered. In my state, it does not even quarantee that you will get visitation rights. So, if you wanted to change the child's name - you should have married the mother!! . That is the mother's choice and ultimate decision. ( Full Answer )
