British Citizenship After UK Family Residence

United Kingdom Citizenship
Pathway overview

At a glance

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.

Type
Citizenship by descent
Family line
People with a documented family line to the United Kingdom
Core records
Civil records linking each generation
What to know
Usually a strong right if the facts and records line up
What it gives
Registration gives citizenship otherwise than by descent, so the child can normally transmit British citizenship to a future child born outside the UK.
Main limit
It is not satisfied by the British parent's residence alone or by residence at any earlier time.

Summary

Section 3(5) gives a child born abroad an entitlement to register after the child and qualifying family members complete three years' UK residence immediately before the application. A parent must have been British by descent when the child was born. The application must be made before the child turns 18.

Eligibility

Normally the child and both parents must have been in the UK at the start of the three-year period and each must have no more than 270 days' absence during it. The statute adjusts the two-parent requirements where a parent has died or the parents' marriage or civil partnership has ended, or they are legally separated. Required parental consent must be supplied. There is no discretion to waive the 270-day ceiling.

A child aged 10 or older must meet the good-character requirement. The Home Office assesses conduct under its current April 2026 guidance; applicants should disclose criminal, immigration and other relevant history rather than assume an old matter is ignored.

What This Route Allows

Registration gives citizenship otherwise than by descent, so the child can normally transmit British citizenship to a future child born outside the UK. It also gives the right of abode and access to a British passport. There is no renewal or settlement stage.

What This Route Is Not

It is not satisfied by the British parent's residence alone or by residence at any earlier time. The child and required parent or parents must meet the immediately preceding three-year test. It is also distinct from discretionary section 3(1) registration.

Next Steps

  1. Confirm that a parent was British by descent on the child's birth date.
  2. Choose an application date on which everyone required was present exactly three years earlier.
  3. Reconcile passports and travel records and count each person's absences separately.
  4. Collect school, tax, employment, tenancy and immigration records plus parental consent.
  5. File Form MN1 before age 18 and check the £1,000 child fee or fee-waiver process.
