Apply to Register a Child as a British Citizen

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

You can register a child as a British Citizen by entitlement or discretion. Becoming a British citizen is a significant life event. Apart from allowing children to apply for British passports, British citizenship also allows them to participate more fully in their local community as they grow up. Children who have automatically acquired British citizenship do not need to be registered and can instead apply for a British passport.

Applications to Register a Child as a British Citizen

If your child is not a British Citizen by birth, you can apply for registration of your child as a British Citizen. Unless the child is a British citizen by birth, the child under the age of 18 can be registered as a British citizen by virtue of various sections of the British Nationality Act 1981. As specialist solicitors for the registration of children as British citizens, we can provide expert immigration advice and representations for the following applications for a child to be registered as a British citizen:

Legal Framework for Registering a Child as a British Citizen

The British Nationality Act 1981 contains provisions for children to be registered as British citizens. Various provisions of the British Nationality Act 1981 under which a child can be registered as a British Citizen are as follows:

sections 1(3), 1(3A) and 1(4) provide registration by entitlement of people born in the UK after 1 January 1983
section 1(4) provides an entitlement provision for either a child or an adult

MN1 Application for Registering a Child as a British Citizen

Using the MN1 application form, you can apply for registration of your child under the age of 18 as a British Citizen under one of the relevant sections of the British Nationality Act 1981. Most applications for the registration of children as British Citizens are made using the MN1 form. You can use the MN1 form to register your child both inside and outside the UK. Children under 18 years of age (minors) can make the following applications to the Home Office for registration as British citizens using the MN1 Application under various sections of the British Nationality Act 1981. Children must be under 18 years old when the application is made. Once they reach the age of 18, they must apply for British citizenship as adults, either by registration if they have an entitlement or by naturalisation. The application date is the date the Home Office receives it. If the child is aged 10 or over, they must be of good character.
