British Citizenship by Birth Solicitors in London
We help you prove and secure your British citizenship by birth, with the right evidence first time.
What Is British Citizenship by Birth?
A child born in the UK becomes a British citizen automatically only if at least one parent was a British citizen or held settled status (Indefinite Leave to Remain, or EU Settlement Scheme settled status) at the time of the birth. Most children born in the UK are not automatically British — citizenship usually depends on the parents’ immigration status, not simply on being born on UK soil. Where a child isn’t automatically British, they may still be able to register as one later, often once a parent’s own status changes.
Adam Bernard Solicitors advises parents across London on eligibility checks, registration applications (Form MN1), the 10-year residence route, and first-time child passport applications — and on what to do if an application is refused.
Automatic British Citizenship for Children Born in the UK
Whether a child born in the UK is automatically British depends on their date of birth:
- Born before 1 January 1983: automatically British in almost all cases, regardless of the parents’ status. The main exceptions are children born to a parent serving as a foreign diplomat in the UK, and children born in the Channel Islands during the German occupation in the Second World War.
- Born on or after 1 January 1983: automatically British only if, at the time of birth, at least one parent was a British citizen, or was “settled” in the UK (held Indefinite Leave to Remain, EU Settlement Scheme settled status, or a right of abode).
- Living in the UK until age 10: a child born in the UK who is not automatically British, but who lives in the UK continuously until their 10th birthday (with no more than 90 days’ absence a year), acquires an entitlement to register as British — this is commonly known as the 10-year rule, and it applies regardless of the parents’ immigration status.
When a Child Born in the UK Is Not Automatically British
It’s a common misunderstanding that being born in the UK is enough on its own — it isn’t. A child born in the UK to parents who are both on temporary visas (a work visa, a student visa, or with no current leave) is not automatically a British citizen, even though the birth itself is registered with a UK birth certificate in the usual way. That child may become eligible to register as British later — most commonly once a parent obtains Indefinite Leave to Remain or EU Settlement Scheme settled status, or once the child reaches the 10-year threshold above.
Registering a Child's British Citizenship (Form MN1)
Where a child isn’t automatically British but has become entitled to register, an application is made using Form MN1 (Application for Registration of a Child as a British Citizen), submitted to the Home Office with:
- The child’s full birth certificate
- Evidence of the parents’ nationality or immigration status
- Written consent from everyone with parental responsibility
- A statement from two referees confirming the child’s identity
- The relevant fee — currently around £1,214 for a child’s registration application (this figure changes periodically, so always confirm the current fee on GOV.UK before applying)
Applicants then attend a UKVCAS appointment to provide biometric details. Most straightforward MN1 applications are decided within three to six months, though the Home Office can take longer where further checks are needed. Because eligibility depends on precise dates, parental status history, and consistent documentary evidence, errors on Form MN1 are one of the most common causes of delay and refusal — our solicitors review eligibility and prepare the application before it’s submitted, to reduce that risk.
The 10-Year Rule, Explained
One route that’s often missed: a child born in the UK who lived here continuously for their first ten years — with no more than 90 days’ absence in any year — is entitled to register as a British citizen under section 1(4) of the British Nationality Act 1981, regardless of their parents’ immigration status at any point. This matters for families who arrived on temporary visas, later became undocumented, or whose status changed several times during the child’s early years: the child’s own residence history, not the parents’ paperwork, is what counts here. Evidence typically includes school records, GP registration letters, and other dated proof of continuous UK residence.
Adopted Children and British Citizenship by Birth
A child adopted in the UK by a British citizen parent on or after 1 January 1983 acquires British citizenship automatically on the date the adoption order is made, in the same way as a birth child would. Where the adoption happens outside the UK, or only one adopting parent is British, the position is more complex and usually requires a registration application rather than automatic acquisition. If a valid adoption or parental order later ceases to have effect, citizenship already acquired through it is not revoked.
Your Child's First British Passport
Once citizenship is established — whether automatic or by registration — you’ll need to apply separately for a passport. This is a distinct process with its own documentary requirements (including an approved counter-signatory to confirm the child’s identity) and its own timescales. Our British passport application page covers the full process, fees and how to avoid the errors that most commonly delay a first application.
What Happens if an Application Is Refused
A refusal isn’t the end of the road. The Home Office most often refuses child citizenship applications for insufficient evidence, incomplete documentation, or unresolved questions over a parent’s immigration history. Where that happens, we:
- Review the refusal letter in detail to identify the exact reason given
- Submit a Request to Reconsider where the refusal was based on an error or overlooked evidence
- Prepare a fresh, fully supported application where reapplying is the better route
- Address the specific gaps flagged in the refusal, to reduce the risk of a second refusal
British Citizenship by Birth vs Other Routes
If your child wasn’t born in the UK, or you’re asking about your own status rather than a child’s, a different route may apply:
- Born outside the UK to a British parent — see British citizenship by descent
- An adult applying through UK residence — see naturalisation as a British citizen
- An adult applying through marriage or civil partnership to a British citizen — see British citizenship by marriage
- A parent who needs settled status before a child can register — see settlement and Indefinite Leave to Remain applications
