Whether a child born in the UK is automatically British depends on one central question: was a parent British or ‘settled’ at the time of birth? If not, a child may still qualify through 10 years’ residence, or settle first through a separate 7-year route. We explain each pathway below, including which Home Office guides and forms apply.
TL;DR:
- Section 1(4) requires an application at age 10 or older, continuous UK residence from birth, and no more than 90 days abroad in any year.
- The seven year private life route grants indefinite leave to remain, not citizenship; the ten year registration route gives the child citizenship instead.
- Families should use an entitlement route where available, because discretionary registration may grant citizenship by descent and restrict a child’s ability to pass it on.
- Form MN1 covers most minor applications, while Form T applies to some section 1(4) cases; apply early because the received date controls eligibility before 18.
- Build an overlapping record of passports, school or medical records, and travel dates, since gaps can undermine proof of continuous residence and annual absences.

Automatic acquisition at birth: who is automatically a British citizen?
A child born in the UK is automatically British if, at the time of birth, at least one parent was a British citizen or was ‘settled’ in the UK, meaning they held indefinite leave to remain or equivalent status. This rule has applied since 1 January 1983, when the British Nationality Act 1981 replaced the old principle that birth on UK soil alone conferred citizenship.
A further shift arrived on 1 July 2006: children born to unmarried fathers gained the same automatic rights as those born to married parents, provided the father was British or settled and paternity is properly established. The EU Settlement Scheme has also affected many families, since an EEA parent who holds settled status under the scheme counts as ‘settled’ for this purpose.
Whether citizenship passes ‘otherwise than by descent’ or ‘by descent’ matters for the child’s own children later in life:
- A child born in the UK to a settled or British parent is usually British otherwise than by descent, which carries full transmission rights.
- A child who becomes British only through a parent who is British by descent may face restrictions on passing citizenship to their own children born abroad.
Registration routes for children who are not British at birth
When neither parent was British or settled at birth, a child is not automatically British, but several statutory registration routes may still apply. Identifying the correct section matters, because Guide MN1 sets out different tests, evidence and outcomes for each.
- Sections 1(3) and 1(3A) give an entitlement while the child is still a minor if a parent later becomes settled, naturalises, or joins the armed forces.
- Section 1(4) is the 10-year residence route, covered in detail below.
- Sections 3(2) and 3(5) apply to children born abroad to a parent who is British by descent, subject to three-year UK residence tests either before or after the birth.
- Section 3(1) is a discretionary registration power used in a narrower range of cases where no clear entitlement exists.
- Section 4D offers a special route for children born overseas to parents serving in the armed forces.
Home Office guidance stresses that an entitlement route should always be used ahead of discretionary registration where one applies, since discretionary registration can result in citizenship by descent rather than otherwise than by descent.
The 10-year route (section 1(4)) and the 90-day absence test
Section 1(4) gives an entitlement to registration for a child who has spent their first decade of life in the UK without automatically qualifying at birth. Guide T sets out the statutory checklist precisely:
- The child was born in the UK on or after 1 January 1983.
- The child is aged 10 or over at the date of application.
- The child has lived in the UK continuously for the first 10 years of life.
- The child was not absent from the UK for more than 90 days in any one of those 10 years.
- The child is of good character if aged 10 or over.
Counting absences accurately is often the deciding factor, and if you need to exchange your foreign driving licence during the family’s transition, expert guidance is available. School attendance letters, GP or medical records, and a complete set of passports covering the whole period give the clearest picture of where the child actually was, and these are the documents Home Office caseworkers rely on most when assessing the 90-day rule.
Pro Tip: Keep a simple year-by-year log of every trip abroad from birth, with dates and passport stamps attached, so the 90-day calculation for each birthday year is ready well before you apply.
Seven-year private life route (ILR) versus citizenship
A separate route exists for children who have lived in the UK continuously for seven years but do not meet the automatic or 10-year citizenship tests. Under Appendix Private Life, a dependent child with seven years’ continuous residence can apply to settle, gaining indefinite leave to remain rather than citizenship itself.
- ILR grants permanent settlement status but is not the same as holding a British passport.
- Citizenship, once registered, transmits more straightforwardly to the child’s own children born in future.
- Families sometimes use the seven-year route as a stepping stone while the child builds towards the fuller 10-year entitlement.
Evidence expectations mirror the 10-year route: consistent school enrolment, medical records and travel history showing genuine continuous residence throughout the period claimed.
How to apply: forms, evidence, fees and timings
Getting the paperwork right matters as much as meeting the underlying test, and the date an application is received by the Home Office is treated as the formal application date, which is critical when a child is approaching 18.
- Use Form MN1 for most minor registrations, and Form T where the Home Office specifically directs it for section 1(4) cases.
- Gather a full birth certificate, every passport covering the residence period, school or medical records showing continuous presence, and proof of a parent’s settled status where that is being relied upon.
- Book biometric enrolment through the standard Home Office process, since even young children typically need to provide biometric information as part of the application.
- Check current fees and processing times on GOV.UK before submitting, as these change periodically and vary by route.
- If a child is nearing their 18th birthday, start the application as early as possible, because the received date, not the decision date, determines which entitlement applies.

Common pitfalls and next steps
Most refused or delayed applications share the same handful of causes, and most are avoidable with careful preparation.
- Miscounting absence days is the single most common error, particularly when a family has travelled frequently for holidays or to visit relatives abroad.
- Submitting thin documentary evidence, such as a single passport with gaps, instead of a complete, overlapping record across school, medical and travel history.
- Assuming birth in the UK alone guarantees citizenship, when in fact parental status at the time of birth is the deciding factor in most cases.
Pro Tip: If an application is refused, ask whether administrative review or a fresh application with stronger evidence is the faster route, since this depends heavily on the specific grounds for refusal.
Where a child turns 18 before an application is resolved, the case generally moves into adult naturalisation territory, which carries its own residence and good character tests, so timing the original application correctly is worth the effort.
When to get expert help with a child’s registration
We see the widest range of difficulty in cases with patchy travel records, borderline good character questions for older children, and families working against a tight deadline before a child’s 18th birthday. These are exactly the situations where a second pair of trained eyes on the evidence file makes the difference between a smooth application and a refusal. If your child’s case feels complicated, reaching out early costs little and often saves months.

FAQ
Do you get British citizenship if you are born in the UK?
Not automatically in every case. A child born in the UK is automatically British only if a parent was British or settled at the time of birth; otherwise, the child may qualify later through registration.
Do children automatically get citizenship from their parents?
A child automatically takes British citizenship from a parent who was British or settled in the UK at the moment of birth. If neither parent met that condition, the child does not automatically become British and would need to apply through one of the registration routes, such as the 10-year entitlement.
Can a child born in the UK get indefinite leave to remain after 5 years?
The standard continuous residence period for the private life settlement route is seven years, not five, under Appendix Private Life. Indefinite leave to remain through that route is a settlement outcome, separate from British citizenship itself.
What happens if an Indian baby is born in the UK?
The same rules apply regardless of the parents’ nationality: a baby born in the UK to Indian parents is automatically British only if a parent is British or settled in the UK at the time of birth. If not, the family can still explore the 10-year residence entitlement or, once settlement is achieved, the registration routes under sections 1(3) and 1(3A). India does not generally permit dual citizenship, so families should take independent advice on that aspect alongside their UK application.
What evidence do I need for a child’s citizenship application?
Core evidence typically includes the child’s full birth certificate, a complete set of passports covering the relevant residence period, and school or medical records confirming continuous presence in the UK. Proof of a parent’s settled or British status is also required where the application relies on that fact.
