My question involves name change laws in the State of: GA
I had my son 13 years ago and I am the only parent on the birth certificate. He has my maiden name. Paternity has never been established. I have been married for 8 years and we want to change my son's last name to match the rest of the family. I have no idea where his biological father is. He has never tried to contact/help us. I think he gave me about $400 about 10 years ago.
Do we need a lawyer or can my husband and I do it ourselves? Any advice is appreciated. Thanks in advance!
