Marriage Certificates and Name-Change Admin

Nobody warns you that the wedding is, administratively, the easy part. The certificate and the name-change process afterwards is where the paperwork actually piles up, and it's worth knowing the shape of it before the day so you're not improvising in the weeks after.

After your ceremony, your marriage gets registered and you'll be issued a marriage certificate (in England and Wales this now comes from a registration process completed after the ceremony rather than being signed on the day itself - the exact mechanics have changed in recent years, so don't assume the process your parents describe from their own wedding still applies). You'll likely want more than one certified copy, since several organisations will want to see an original rather than a photocopy.

If you're changing your surname, there's no separate legal process required in the UK - you don't need a deed poll for a straightforward marital name change. Your marriage certificate itself is treated as sufficient legal evidence of the change. What you actually need is patience, because every organisation wants to be told separately and most want to see the certificate.

A sane order to do it in, from experience watching friends do this badly:

1. Passport first - it takes the longest and you'll want it back before any travel.
2. Driving licence next, since you'll likely need your updated passport as supporting ID for some of the online forms.
3. Bank accounts and building societies.
4. HMRC and your pension provider - easy to forget, annoying if you do.
5. Everything else - GP registration, dentist, employer HR, subscriptions, delivery accounts - in whatever order you can be bothered with. Nobody's card gets declined over an outdated Ocado name.

If you're not changing your name, none of this applies to you beyond keeping your certificate somewhere safe - but do keep it somewhere safe. It's one of those documents you don't think about until the one time you need it urgently.
