I live in TN and we found out that my sons 19 month old is not his biological daughter. Can the mother take his name off the birth certificate? He did the test to see if child is his but he still wants to be her dad. Son and daughter-in-law getting divorced. He was also in process of adopting the 3 year old and mom stopped 1 week before came final, he has raised her since she was born. Is there anything he can do about that.
