I am legally married but I have not changed my last name. I dont really think it makes a difference, and to be honest I am really lazy to go through the process lol. Like Ive mentioned before DH has my name tattoed on him so yesterday he said to me " babe if ur not going to tattoo my name on u then can u atleast change ur last name? I feel like you dont have anything of me". I said "well what about the kids? what more do u need?" lol. Anyways I do want to change my last name "eventually" lol but I will only add his I am not removing my dad's . Does anyone know what I need to do to change it? dont I have to go to social security office and DMV? How long is the whole process? do i need to pay?
