See if you're a match →UK Section 3(5) is a registration route for minor children of a British citizen by descent when the child and parents build the required UK residence. It generally requires the child to be under 18, proof of the parent's British status, and the family's UK residence evidence.

Summary
Section 3(5) of the British Nationality Act 1981 can let a child under 18 register as British when they were born outside the UK to a British citizen by descent parent and the family has lived in the UK for the required 3-year period immediately before the application.
This route is about the child's and parents' recent UK residence. It is not triggered just because the family has an old UK ancestor.
Eligibility
The child may be eligible if all of the following are true:
- The child was born outside the UK.
- The child is under 18 when the application is made.
- A parent was a British citizen by descent when the child was born.
- The child and both parents were in the UK at the start of the 3-year period ending with the application date, unless a listed one-parent exception applies.
- The child and parents were not outside the UK for more than 270 days during that 3-year period.
- The required parent or parents give written consent.
- The child meets the good-character requirement if aged 10 or older.
- The child is not already British.
What This Route Allows
Registration under Section 3(5) gives British citizenship otherwise than by descent. That can matter for the child's own future children born outside the UK.
What This Route Is Not
This is not a fallback for remote UK ancestry. The British-by-descent parent must have held British citizenship when the child was born, and the family must meet the specific UK residence and consent requirements.
It is also different from Section 3(2), where the British-by-descent parent's residence before the child's birth is the key residence fact.
Next Steps
- Confirm which parent was British by descent when the child was born.
- Gather proof of that parent's British citizenship by descent.
- Gather passports, school records, tenancy records, council tax records, NHS or GP records, and other evidence showing the child and parents' UK residence during the 3-year period.
- Check the 270-day absence limit carefully.
- Confirm the required parental consent can be given.
- Prepare the child registration application and check the current Home Office form, fee, and evidence guidance before filing.
