How do I change my name after marriage or divorce?

You do not need a deed poll to take a spouse's surname, or usually to go back to a former one. The evidence each organisation wants, the order that works, and the passport rules that catch people before a honeymoon.

Short answer

To take your spouse's or civil partner's surname, including a double-barrelled version of both, send a copy of the marriage or civil partnership certificate — no deed poll is needed. To revert after divorce, the marriage certificate with the final order or decree absolute usually suffices, though some organisations insist on a deed poll. Do the passport and driving licence first, because everything else asks to see one of them.

The confusion here is that name change is not a single legal event. Nothing registers your new name centrally; you simply start using it and prove the connection to each organisation with a certificate. The two exceptions that generate most of the questions are the passport, which has its own rules and its own timing trap before a honeymoon, and blended or invented surnames, which a marriage certificate cannot evidence.

Step by step

Know that no deed poll is needed for the ordinary cases.Taking your spouse's or civil partner's surname, or double-barrelling both surnames, is evidenced by the marriage or civil partnership certificate. That is the official position and it covers the great majority of changes.
Buy enough certified copies.Several organisations want to see an original and some keep it for weeks. Order two or three at the point you order the first — it is cheaper than ordering them one at a time later.
Decide about the passport timing before booking a honeymoon.You get a new ten-year passport and any time left on the old one is not carried over. You can apply up to three months before the ceremony for a passport post-dated to the wedding date, countersigned by the registrar or officiant — but the old passport is cancelled, so you cannot travel on it in the meantime, and some countries will not issue a visa for a post-dated passport.
Do the passport, then the driving licence.They are the documents everything else asks to see, they take the longest, and they need originals rather than copies. Updating a driving licence for a name change is free, and you can keep driving while you wait.
Update the vehicle log book as well as the licence.The V5C is a separate record from the driving licence and both need changing. People routinely do one and forget the other.
Tell HMRC.Online or through the HMRC app. Your National Insurance number never changes; only the name attached to it does. Payroll should be told separately by you or your employer.
Re-register to vote.Registration is by name, so a change means re-registering. It is quick, it is online, and an out-of-date electoral entry causes problems with credit and identity checks later.
Work through the rest as a list.GP and NHS records, dentist, bank and building society accounts, mortgage, credit cards, Land Registry title if you own property, insurance policies, pension providers, TV licence, utilities, professional bodies and any subscriptions. Do them in a single sitting with the certificates in front of you.
Reverting after divorce: check what each body wants.The usual combination is the marriage certificate together with the final order or decree absolute. Some organisations will only change a name back on a deed poll. Ask before you assume.
Note that the passport office asks for something different on divorce.For reverting to a previous surname, HM Passport Office asks for your birth certificate, a signed statement that you have reverted for all purposes, a document showing you using the new name, and a marriage certificate showing both names. It does not ask for the final order, which surprises almost everyone.
Use a deed poll for anything a certificate cannot evidence.A blended or invented surname, a change of forename, or a change unconnected to a marriage. An unenrolled deed poll is sufficient for most organisations; an enrolled one is a court process with its own fee and requires a statutory declaration.

Tips

Write the list of organisations before you start and tick them off. Missing one usually surfaces at the least convenient moment.
Ask each organisation whether a certified copy is acceptable. Many accept one, which saves posting originals around the country.
Do the electoral roll early. It feeds identity and credit checks and an out-of-date entry is a slow problem to unpick.

Common mistakes

Applying for a passport in a new name before the wedding — Unless you use the post-dated route deliberately, the old passport is cancelled and you cannot travel on it. The post-dated route has its own visa complications.
Changing the driving licence and forgetting the V5C — They are separate records held for separate purposes, and a mismatched vehicle record causes problems at insurance renewal and on sale.

If it doesn't work

An organisation insists on a deed poll

Cause: Their own policy, which they are entitled to have — Fix: Ask what their policy actually requires in writing. An unenrolled deed poll is straightforward and inexpensive, and is usually accepted where a certificate is not.

Your honeymoon booking is in your married name

Cause: The passport is still in the previous name — Fix: Travel in the name on the passport, or use the post-dated passport route. Airlines match the ticket to the passport, and a mismatch stops you at check-in.

You have run out of certificate copies

Cause: Organisations retaining originals — Fix: Order more from the register office or the relevant registry. Some organisations accept a copy certified by a solicitor or a bank, which is cheaper — ask first.

Questions people ask

Can I double-barrel our surnames on a marriage certificate?

Yes. HM Passport Office states expressly that the marriage or civil partnership certificate covers double-barrelled names. A blended or invented surname is different, because the certificate cannot evidence it.

Do I have to change my name at all?

No. There is no obligation either way, and no new passport is needed if you marry and keep your name.

How long does the whole process take?

The passport and licence take weeks; the rest is an afternoon once you have those. Plan around the passport, because it is the long pole and it needs the original certificate.

Is it different in Scotland or Northern Ireland?

The principle is the same. Scotland refers to a decree of divorce rather than a final order, and Northern Ireland retains decree nisi and decree absolute. Northern Ireland also has its own registration route for recording a name change with the registrar.
