My question involves name change laws in the State of: Florida
my daughter birth certificate currently has her last name as my previous boyfreinds and him as the father too. We were never married. He is not the father. And agrees to sign his name off. After a paternity test i contacted her biological father who wants his name on the birth certificate. I would also like to change her last name to my name. She is only 3 months old. How do i change her last name and the father in the state of florida?
