In an unmarried situation who gets to chose the child's surname - the birth mother - or the father

What happened to my previousquestion in the same category

If the father signs birth certificate in hospital that he is the father, the baby takes his surname. If he fails or does not want to sigh, the baby takes your surname.

If the father signs birth certificate in hospital that he is the father, the baby takes his surname. If he fails or does not want to sigh, the baby takes your surname.

Thanks for your reply but does the same apply in Australia

In the US, the mother chooses ALL names, regardless of paternity, marital status, the father being present and signing the birth certificate.

The father can challenge the naming in court at a later date, but it's a hard battle for a minor gain in most cases.
