So I need to change the name on my account, as I'm divorced and have now gone back to using my birth name. I've been sent a form to complete to do this, but it asks me to send documentation - "marriage certificate, your civil partnership certificate; or your Deed poll documentation". None of these apply to me. You don't need a deed poll to revert back to the surname on your birth certificate. I've already changed my passport back to my "new" name, but I can't send that. So the question is what do I need to send and how please?
