My question involves name change laws in the State of: GA
I've recently learned via my son that my ex is getting remarried. During our discussion he mentioned that he would have a new last name. I wish to get in front of this as I do not agree with this. My ex-wife from what I recall has legal and physical custody even though my son is mostly here due to here travels. We have visitation every other weekend and most holidays. Do I have any legal rights in Georgia to prevent this? What is my best course of action?
