My question involves name change laws in the State of: FLORIDA
After 8 months of asking and having to go to court to get a court order, I finally got a dna test done on my son who the mother told me there was a 50/50 chance of him being mine. Since finding out I have began paying support and getting visitation, my question is, what are my rights as to being able to change his last name? Had she given me the test once he was born, like i requested, i would have pushed the issue then. Just curious if I have any legal rights here. Thanks in advance.
