I'm an unwed mother-to-be in Texas, and I would like for my child to have my surname. The father will be present at birth and will sign the birth certificate, however, we cannot agree on the surname, as he wants the child to have his surname. I need to know the Texas law on surnames. Is it ultimately the mother's choice or can he challenge the decision in court? Please help. Thank you.What is the name of your state (only U.S. law)?
