Yes - if you serve in the British Army, Royal Navy or Royal Air Force you have exactly the same legal right to change your name as any other UK adult, and you do not need your commanding officer’s permission to do it. What is different is the admin that follows. Once your name is legally changed, you must have your records updated on JPA (Joint Personnel Administration) through your unit, draw a new MOD 90 identity card, and - if you hold security clearance - report the change to UK Security Vetting. Get the order right and the whole thing is painless. Get it wrong and you risk pay errors, a flagged record, or a vetting query.
The legal bit comes first: your deed poll
The military cannot change your name for you. Your name is changed by a legal instrument that exists entirely outside the chain of command - in almost every case, a deed poll. The Army, Navy and RAF simply record the change once it has already happened in law.
There are two routes, depending on why you’re changing:
- Marriage, civil partnership or divorce: your marriage certificate, civil partnership certificate or decree absolute is itself the legal document. You do not need a deed poll to take a spouse’s surname or revert to a maiden name.
- Any other change - personal choice, new first name, double-barrelling, gender transition: you need a deed poll.
An unenrolled adult deed poll is the document the overwhelming majority of people use, and it is legally valid for every government and service purpose - HM Passport Office, DVLA, HMRC, your bank, and the MOD all accept it. Around 98% of UK name changes are unenrolled. Our professionally printed deed poll starts at £14.49, with same-day dispatch on orders placed before 3pm and free Royal Mail Tracked delivery. A solicitor would charge £150-£300 for the identical document, which is money you simply do not need to spend.
Two practical points that trip service personnel up:
- It must be the original. Your UPO, HM Passport Office and DVLA all need the original wet-ink signed deed poll, not a photocopy or scan. Order at least one spare original if you have a long list of organisations to update.
- The witness must be independent. Your witness has to be an adult aged 18 or over who is not a relative, partner or anyone living at your address. A colleague from another section, your padre or a friend is fine.
You can sign your own deed poll from age 16, so most serving personnel can act entirely on their own behalf without anyone’s consent.
Step 1: Sort your legal document
Obtain your deed poll (or locate your marriage certificate / decree absolute). Do this before you tell anyone in your unit, because admin staff cannot start until the legal change is real and the paperwork is in hand.
Step 2: Notify your unit and update JPA
This is the step that actually keeps you paid. Take your original deed poll or certificate to your unit’s administrative office - the Unit Personnel Office (UPO) in the RAF, the RAO or Company Clerk in the Army, or the Ship’s Office / UPO in the Royal Navy. They will update your record on JPA (Joint Personnel Administration), the tri-service system that controls your pay, allowances, pension contributions, leave and expenses.
Why this matters so much: if your bank account name and your JPA name drift apart, salary payments can bounce or be delayed, and your pension record can end up under the wrong name. Updating JPA promptly keeps your pay, your P60 and your service pension all aligned to your new legal identity. Ask your admin staff to confirm the effective date and to give you a printout or screenshot of the updated record for your own files.
A quick note for the chain of command: while you do not need permission to change your name, your unit does expect to be notified, and that’s exactly what handing in the document achieves. You are not asking - you are informing.
What about your MOD 90?
Your MOD 90 (the standard tri-service identity card) carries your name, so once JPA is updated you’ll need a replacement. Your unit admin or guardroom will arrange a re-issue once the new details are showing on the system. Keep using your old card until the new one is in your hand, and follow local instructions for returning or destroying the old one. Don’t throw it in a bin - it’s a controlled identity document.
Step 3: Tell UK Security Vetting - this is non-negotiable if you’re cleared
If you hold security clearance - Counter Terrorist Check (CTC), Security Check (SC) or Developed Vetting (DV) - a name change is a change of personal circumstances that you are required to report to UK Security Vetting (UKSV). This is one of the conditions of holding clearance, and failing to report changes is exactly the sort of thing that raises questions at your next review.
Report it through the NSVS (National Security Vetting Solution) portal if you have an account, or through your Unit Security Officer (USO) / Security Controller, who will know the current process for your establishment. A straightforward name change does not put your clearance at risk on its own - vetting is concerned with honesty, financial stability and conduct, not the fact that you’ve chosen a new surname. What does cause problems is a record that doesn’t add up, so the goal is a clean paper trail: your legal name, your JPA name and your vetting record all matching.
If you’re changing your name partly to put distance between yourself and a difficult past, it’s worth understanding how disclosure works more broadly - our guide on whether you can legally change your name with a criminal history covers what vetting and the police can and can’t see, and why a name change never erases your record.
Will it affect my career?
No. Changing your name has no bearing on your rank, trade, branch, seniority, assignments or promotion prospects. It is an administrative matter, not a career one. The only realistic exception is the obvious one: a name that is offensive, brings the service into disrepute, or is clearly adopted to deceive could be challenged. A normal change - a new surname after marriage, reverting to a birth name, or a name reflecting your identity - is entirely routine and units process them regularly.
The order of action, at a glance
- Get the legal document - an unenrolled deed poll, or your marriage certificate / decree absolute.
- Take the original to your UPO / RAO / Ship’s Office so they update JPA.
- Report the change to UKSV via NSVS or your Unit Security Officer if you hold CTC, SC or DV.
- Collect your new MOD 90 once the system reflects your new name.
- Update everything else - passport, driving licence, bank, HMRC, NHS. The DVLA update is free; banks, HMRC and the NHS are free too. A new passport costs £102 online (or £115.50 by post) if you need one re-issued, though that’s not specific to service personnel.
Frequently Asked Questions
Do I need my commanding officer’s permission to change my name?
No. You can sign a deed poll without anyone’s approval. You are required to notify your unit afterwards so JPA and your MOD 90 can be updated, but the legal change is yours to make.
Will a name change affect my security clearance?
Not on its own. You must report it to UK Security Vetting as a change of personal circumstances - through NSVS or your Unit Security Officer - but a routine name change does not jeopardise CTC, SC or DV clearance. The key is reporting it promptly so your records stay consistent.
Is an unenrolled deed poll accepted by the MOD?
Yes. An unenrolled deed poll is legally valid and accepted for updating JPA and re-issuing your MOD 90, just as it is by HM Passport Office, DVLA, HMRC and banks. Enrolment at the Royal Courts of Justice (£53.05) is optional, publishes your change in the London Gazette, and adds no legal validity.
What do I do about my pay and pension during the change?
Update JPA as soon as your deed poll is signed. JPA drives your pay, allowances and pension record, so keeping it aligned with the name on your bank account prevents delayed or bounced salary payments and keeps your pension under the correct name.
I’ve changed my name for work but kept my old name professionally - is that allowed?
Many people use a working name that differs from their legal name. If that’s your situation, see our guide on matching your professional name to your legal identity for how to keep documents, payroll and credentials consistent.
Does the witness on my deed poll need to be a service colleague?
No. The witness just needs to be an independent adult aged 18 or over who isn’t a relative, partner or someone living at your address. A colleague, a friend or your unit padre all qualify.
