Morning everyone. We got married in May and I need to change my name, I am keeping my middle name but taking his surname and dropping mine, not double barrel. Is my marriage certificate enough to just change it or do I need deed poll? I'm confused as my marriage name is in my surname as you sign it with you current name so how is this proof of new name? Is there an official way to change it or do I just now go by new name and tell banks etc? Thank you
