United Kingdom Citizenship
Pathway overview

At a glance

A child born in the UK after 1982 may be entitled to register as British if they were not British at birth but later a parent became British, settled, or joined the UK armed forces. The child generally must apply before turning 18 and meet good-character rules if aged 10 or older.

Summary

A child born in the UK on or after 1 January 1983 who was not British at birth is entitled to register under section 1(3) if, while the child is under 18, either parent becomes British or settled in the UK. Section 1(3A) gives a related entitlement where a parent becomes a member of the UK armed forces after the birth. The application must be made before age 18.

Eligibility

The child must have been born in the UK and not already be British. For section 1(3), a legal parent must later have become British or acquired a status amounting to settlement—such as indefinite leave or EUSS settled status—while the child was a minor. For section 1(3A), the child must have been born on or after 13 January 2010 and a parent must have joined the UK armed forces while the child was under 18.

A child aged 10 or older must meet the current good-character requirement. Registration is a statutory entitlement if the facts are met; it does not depend on the child's own immigration status. The fee from 8 April 2026 is £1,000, with an affordability fee waiver available for an eligible child.

What This Route Allows

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

What This Route Is Not

It is not automatic when the parent later settles: an application must be filed before the child's 18th birthday. It is also not needed if the parent was already British or settled at birth, because the child may have been British automatically.

Next Steps

  1. Obtain the full UK birth certificate and confirm the child was not British at birth.
  2. Obtain the parent's naturalization, registration, ILR, EUSS or armed-forces evidence with the effective date.
  3. Address identity, parentage and any good-character matters.
  4. File Form MN1 before age 18 and request a child fee waiver first if necessary.
