See if you're a match →UK Section 3(2) is a registration route for minor children of a British citizen by descent where the British parent has lived in the UK for the required period. It generally requires the child to be under 18, proof of the parent's British status, and evidence of the parent's UK residence.

Summary
Section 3(2) 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.
This route is not based on having a distant UK ancestor. The key facts are much narrower: the child must have had a British-by-descent parent at birth, that parent's own parent must have been British otherwise than by descent, and the British-by-descent parent must have lived in the UK for the required period before the child was born.
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 British-by-descent parent's parent was British otherwise than by descent, or would have become so under the transition rules.
- The British-by-descent parent lived in the UK for a continuous 3-year period before the child's birth.
- The parent was not outside the UK for more than 270 days during that 3-year period.
- The child meets the good-character requirement if aged 10 or older.
- The child is not already British.
For children born on or after 21 May 2002, residence in a qualifying British overseas territory can also count toward the parent's 3-year residence requirement.
What This Route Allows
Registration under Section 3(2) gives British citizenship by descent. It can be a strong entitlement where the parent and grandparent status facts line up and the records are complete.
What This Route Is Not
This is not a general grandparent, great-grandparent, or remote-ancestor route. A UK-born grandparent matters only because they may explain why the parent was British by descent and why Section 3(2) can apply.
This is also not the same as Section 3(5), where the child and parents build the required UK residence immediately before the application.
Next Steps
- Confirm which parent was British by descent when the child was born.
- Confirm that parent's parent was British otherwise than by descent.
- Gather civil records connecting the child, parent, and grandparent.
- Gather evidence of the British-by-descent parent's 3-year UK or qualifying-territory residence before the child's birth.
- Prepare the child registration application and check the current Home Office form, fee, and evidence guidance before filing.
