If u want to change ur name to ur husbands, its best to do it this way
old-new
My reasoning is for ID. I get so many people goming into work & they changed their lastname to their husbands & didn't keep thiers, its hard but I have to refuse them if I have her old name only.
But if her ID had both names on it, then ID is never a problem.
I plan to do his when I get married. I want his name & I want mine. Its just easier, u never know when ur gonna need either or.
