Registering a Child Born Abroad to a Member of HM Forces - Section 4D Application

: Written by: Arshad Mahmood; Last Updated: 03 May 2026

Under Section 4D of the British Nationality Act 1981, a child born abroad to a parent serving as a member of the UK armed forces can qualify for registration as a British Citizen if:

the child was born on or after 13 January 2010
the child was born outside the UK and the British overseas territories
both parents consent to the child being registered as a British citizen. (If one of the parents has died, then only the consent of the surviving parent is required.)

For the purpose of an application for registration of a child under Section 4D of BNA 1981, “member of the armed forces” means either:

a member of the regular forces within the meaning of the Armed Forces Act 2006
a member of the reserve forces within the meaning of the 2006 Act, subject to service law by virtue of section 367(2)(a)-(c) of that Act.

However, a person is not regarded as being a “member of the armed forces” if, for example, they are:

a member of the forces raised in a British overseas territory who is serving, or undergoing training, with the UK armed forces
a member of another country’s armed forces who is attached to the UK armed forces (such as part of a coalition force)
