What is the name of your state? ca my son went to visit his son yesterday and his ex girlfriend said she was changing his name to her last name and wanted me to give up all rights to him. I said no way. can she legally do that?
This post makes no sense, but I'll give it a try anyway.
The mother of the child cannot change the kid's name without the father's agreement. At least to my knowledge she can't. Use the search function and focus only on CA law. Especially see posts by "IAAL" because he is a Calif attorney.
Grandma has NO rights whatsoever. That makes no sense. She has no rights to give up, and she has no place in the discussions about the child's future. Legally.
