Going back to your birth name after a marriage
For your passport, GOV.UK asks for your birth certificate, your marriage or civil partnership certificate showing both names, a document showing you use your old name, and a statement signed by you saying you’ve gone back to it for all purposes. Divorce papers aren’t on the list. GOV.UK: divorce or returning to a previous surname
Banks and other organisations set their own rules, and some want a decree absolute or final order, or a deed poll, before they’ll change you back. Our guides to changing your name after divorce and changing your name while separated show who asks for what.
One document for everyone. A deed poll back to your birth name saves explaining the signed statement route to every bank, insurer and employer, and it doesn’t depend on your divorce paperwork. It’s £14.95, posted free.
