For changing your name in the UK, you need a deed poll, not a statutory declaration. A deed poll is the document that legally changes your name and is accepted everywhere - passports, the DVLA, banks, HMRC and the NHS. A statutory declaration is a sworn statement of fact for a witnessing official; it is occasionally used to evidence a name change in niche situations, but for an ordinary UK name change it is the wrong tool. If you are simply changing your name, order a deed poll and move on.
The one-sentence difference
A deed poll is a deed: a binding legal document in which you renounce your old name and adopt a new one, signed by you and an independent witness. A statutory declaration is a written statement that you formally swear is true before a solicitor, commissioner for oaths or notary - the same kind of document people use to declare lost property, confirm identity or attest to facts in a dispute.
Both can carry your name, but they do different jobs. A deed poll does the name change. A statutory declaration merely states something to be true. That distinction is why almost every UK organisation asks for a deed poll and not a stat dec.
Why a deed poll is what you actually need
Under English law you can change your name simply by using a new one consistently, but to update your passport, driving licence and bank accounts you need documentary proof. A deed poll is the evidence record-holders ask for by name. An unenrolled deed poll - the standard, professionally printed document - is legally valid and accepted by HM Passport Office, the DVLA, HMRC, banks, the NHS, employers and schools. Around 98% of UK name changes are unenrolled, and there is no legal benefit to paying more.
The practical advantages are decisive:
- Cost. A professionally printed deed poll from UK Name Change starts at £14.49, with same-day dispatch if you order before 3pm and free Royal Mail Tracked delivery. A solicitor preparing the same document would typically charge £150-£300+.
- No appointment. A deed poll needs only your signature and that of one independent adult witness. A statutory declaration must be sworn in front of a solicitor or commissioner for oaths, usually for a fee and by appointment.
- Universal acceptance. Every major UK organisation recognises a deed poll as proof of a name change. A stat dec is far more likely to prompt questions, because staff simply see them less often.
For the overwhelming majority of people, that settles it. If you want a valid document ready to use within days, order an adult deed poll and you are done.
Deed poll vs statutory declaration at a glance
| Deed poll | Statutory declaration | |
|---|---|---|
| What it does | Legally changes your name | Swears a fact is true |
| Who signs/witnesses | You + one independent adult witness (18+) | You, sworn before a solicitor or commissioner for oaths |
| Typical cost | From £14.49 | Solicitor’s fee, usually per declaration |
| Accepted for UK name change | Yes - everywhere | Rarely; only in specific edge cases |
| Appointment needed | No | Yes |
The rare cases where a statutory declaration is used
A statutory declaration is not useless - it is just for different problems. The situations below are genuinely uncommon, and even then a deed poll usually still does the heavy lifting. A stat dec tends to appear as a supporting document, not the main one.
Some foreign embassies or authorities request one
If you hold a non-UK passport, the issuing country may have its own name-change procedure and may ask for a sworn statement rather than a British deed poll. This is a requirement of that country’s rules, not UK law. Always check directly with the relevant embassy or consulate, as formats vary widely from one country to another.
Confirming a name already in long-term use
Occasionally someone has used a name for years without ever formalising it - on bills, employment records and correspondence - and an organisation asks them to swear a declaration confirming the name they are known by. This is about attesting to an existing, established fact rather than making a fresh change. For a clean, forward-looking change of name, a deed poll is still the simpler route.
Reverting to a previous name without the usual paperwork
After divorce, you can normally revert to a former or maiden name using your decree absolute or marriage certificate - no deed poll required. But if those documents are missing, a statutory declaration is sometimes accepted to confirm your previous name. Even here, many people find a deed poll the faster, more universally recognised option for putting the matter beyond doubt.
If your situation isn’t on this short list, you almost certainly need a deed poll. For the full rules on when a deed poll is required - and when no document is needed at all - see our guide on whether you have to use a deed poll to change your name in the UK.
A common point of confusion: titles
You do not need a deed poll or a statutory declaration to change a title such as Mr, Mrs, Ms, Mx or Dr. A title is not legally part of your name, so most organisations will update it on request. Save the formal paperwork for an actual change of forename or surname.
Getting your deed poll right the first time
Because nearly everyone needs a deed poll rather than a stat dec, it is worth getting the details right:
- Age. Anyone aged 16 or over can change their own name and sign their own deed poll. For under-16s, everyone with parental responsibility must consent.
- The witness. Your witness must be an independent adult aged 18 or over - not a relative, partner or anyone living at your address.
- The original document. HM Passport Office, the DVLA and banks need the original, wet-ink signed deed poll, not a photocopy or scan.
Enrolment at the Royal Courts of Justice is entirely optional. For £53.05 it publishes your name change in the London Gazette and takes 2-3 weeks, but it adds no legal validity to your deed poll. The unenrolled version does exactly the same job for your passport, licence and bank.
It also helps to understand why so many “free” or improvised shortcuts fail in practice. Our explainer on why some name-change alternatives are invalid covers the traps to avoid before you rely on the wrong document.
Frequently Asked Questions
Is a deed poll or a statutory declaration cheaper?
A deed poll is far cheaper. A professionally printed deed poll starts at £14.49, whereas a statutory declaration must be sworn before a solicitor or commissioner for oaths, who charges a fee. A solicitor preparing a name-change document from scratch would typically charge £150-£300+.
Will the passport office accept a statutory declaration?
HM Passport Office expects a deed poll as proof of a UK name change. A statutory declaration is not the standard document and is much more likely to cause delays or questions. To update your passport smoothly, use the original, wet-ink signed deed poll.
Do I need a solicitor for either document?
No. A deed poll only needs your signature and an independent adult witness - no solicitor and no appointment. A statutory declaration does require swearing before a solicitor or commissioner for oaths, which is one more reason a deed poll is simpler for an ordinary name change.
Can I use a statutory declaration to change my name officially?
In most cases, no. For a standard UK name change you should use a deed poll, which is the recognised document for the change. A statutory declaration is only used in narrow situations, such as certain foreign-authority requirements or confirming a name already in long-term use.
Do I need any document to change my title to Mx or Dr?
No. A title such as Mr, Mrs, Ms, Mx or Dr is not legally part of your name, so you don’t need a deed poll or a statutory declaration to change it - most organisations will update it on request.
