What is Form MN1?
Form MN1 is the official Home Office application for registering a child under 18 as a British citizen under the British Nationality Act 1981. Registration is different from naturalisation (which applies to adults). It ensures your child can:
- Live in the UK free from immigration control.
- Apply for a British passport.
- Access healthcare, education, and other rights as a British citizen.
Who can apply through Form MN1?
You can apply if your child:
- Is under 18 at the time of application.
- Was born in the UK and a parent has since become British or settled.
- Was born abroad to a British citizen parent or a parent who later became British or settled.
- Has lived in the UK for 10 continuous years.
- Was adopted under UK law or has strong ties to the UK.
- Falls under discretionary provisions where registration is in the child’s best interests.
Key legal routes
Common sections of the British Nationality Act 1981 include:
