Only if it changes your living arrangements, or you want to change your name.

no change there, do u not have to change name by law ?

No, you don't have to. You can't use any name for the purposes of committing fraud, so for example putting 2 claims in - 1 married name, 1 maiden name. But you can change your name for some purposes, and not for others, or not change it at all.
