My question involves name change laws in the State of: Tennessee
I am the father and the primary residential parent (my son lives with me). I don't know if it makes a difference but his mother is suposed to be paying child support and doesn't, but she has regular vistation and I encourage that. But he has her exhusbands last name & now she is getting ready to be married again....how can I change his last name to mine inexpensively - I don't think she would mind but, I've not discussed this with her, do I need her permission?
