A child born outside the UK is not always British, even where a parent is a British citizen. Where the child is not automatically British, citizenship can be obtained by registering the child while under 18, under the British Nationality Act 1981. This post provides an overview of registering a child born outside the UK as a British citizen.
Is a child born outside the UK automatically British?
A child born outside the UK is automatically British only where a parent was a British citizen otherwise than by descent at the time of the birth. This rule is set out in section 2 of the British Nationality Act 1981. A child in this position is British by descent from birth and does not need to register.
The position is different where the parent is a British citizen by descent. British citizenship by descent passes down only one generation born abroad, so a parent who is British by descent cannot pass citizenship automatically to a child born outside the UK. A child in that position has no automatic claim and must apply to register. The difference between the two kinds of British citizenship is explained further in the guide on the automatic acquisition of British citizenship.
When does a child born abroad need to register?
A child born abroad needs to register where they are not automatically British but can qualify for citizenship under the Act. Registration is an application made while the child is under 18, and it is decided by the Home Office. It is different from automatic acquisition, which happens by law at birth without any application.
The most common situation is a child born abroad to a parent who is British by descent. That child cannot inherit citizenship automatically, but may be able to register, either as of right where the conditions are met, or at the discretion of the Home Secretary. Registration must be applied for before the child turns 18. Once a child reaches 18, the child route closes and an adult route must be used instead.
How can a child born outside the UK register as British?
A child born outside the UK can usually register through one of three routes in the British Nationality Act 1981. Two are entitlement routes, where the child qualifies as of right if the conditions are met. The third is a discretionary route, where the Home Secretary decides whether to register the child. The table below summarises the three.
| Route | Basis | Key conditions |
|---|---|---|
| Section 3(5) | Entitlement after UK residence | A parent was British by descent at the birth; the child and both parents lived in the UK for the three years before the application, with no more than 270 days’ absence each; both parents consent |
| Section 3(2) | Entitlement through a British grandparent | A parent was British by descent at the birth; a grandparent was British otherwise than by descent; the parent lived in the UK for a three-year period before the birth, with no more than 270 days’ absence |
| Section 3(1) | Discretion of the Home Secretary | No fixed conditions; the Home Office considers the child’s circumstances, including their future in the UK, residence and parental consent |
The right route depends on the family’s circumstances, and more than one route may apply. Where a child qualifies under an entitlement route, that route is usually preferred, for the reason explained later in this post. Each route is set out below.
Registering at the Home Secretary’s discretion under section 3(1)
Section 3(1) allows the Home Secretary to register any child as a British citizen where it is considered appropriate. It is a discretionary route, so there is no automatic right to be registered, and each case is decided on its facts. The only fixed requirements are that the child is under 18 and, if aged 10 or over, of good character.
The Home Office guidance sets out how the discretion is normally exercised. It will usually expect at least one parent to be a British citizen, and the child’s future to be seen clearly to lie in the UK. A child who is living outside the UK is normally refused, unless an exception applies, such as a parent in Crown service abroad. The views of both parents are normally sought and considered, even though their consent is not a strict legal requirement on this route.
Registering by entitlement through a British grandparent under section 3(2)
Section 3(2) gives a child born abroad an entitlement to register where a grandparent was British otherwise than by descent. It is designed for the situation where citizenship by descent would otherwise stop at the parent’s generation. Where the conditions are met, the child has a right to be registered.
Three conditions apply. A parent must have been a British citizen by descent at the time of the child’s birth. The child’s grandparent, on that parent’s side, must have been British otherwise than by descent. The parent must also have lived in the UK for a continuous three-year period at some point before the child’s birth. No more than 270 days may have been spent outside the UK in that period. Where these are met, the child does not need to be living in the UK to qualify. A child aged 10 or over must also be of good character.
Registering by entitlement after three years in the UK under section 3(5)
Section 3(5) gives a child born abroad an entitlement to register where the family has lived in the UK for three years. It applies where a parent is British by descent and the whole family has built a recent connection to the UK. Where the conditions are met, the child has a right to be registered.
A parent must have been a British citizen by descent at the time of the birth. The child and both parents must have been in the UK at the start of the three-year period ending with the date of the application. None of them may have been absent from the UK for more than 270 days during that three-year period. Both parents must consent to the registration. There is no discretion to allow longer absences, so the residence condition is applied strictly. Where a parent has died, or the parents are divorced or legally separated, the residence and consent conditions need be met by one parent only.
Does a child registered abroad become British by descent or otherwise than by descent?
The route used decides whether the child becomes British by descent or otherwise than by descent, and the difference affects future generations. A British citizen otherwise than by descent can pass citizenship automatically to their own child born abroad. A British citizen by descent generally cannot.
Registration under section 3(5) gives the child citizenship otherwise than by descent, so the child can later pass it on to a child of their own born abroad. Registration under section 3(2) gives citizenship by descent, which cannot be passed on automatically in the same way. The wider registration routes for children are covered on the British citizenship registration page, and the position for children born in the UK is covered in a separate guide on British citizenship for a child born in the UK.
What does a child need to provide to register?
A child registers using Form MN1, supported by evidence of identity, parentage and any residence relied on. The application establishes the relationship to the British parent, the route relied on, and that the conditions for that route are met. The form and its requirements are covered in the Form MN1 guide.
Several further points apply across the routes. A child aged 10 or over must be of good character, a statutory requirement under the British Nationality Act 1981 that covers any criminal record, immigration history and similar matters. Most applications require the consent of both parents, and on the section 3(5) route this consent cannot be waived except where a parent has died. Two referees are needed, and the rules on who can act are set out in the guide on referees in British citizenship applications. The child must enrol biometric information, with relaxed rules for younger children. A fee is payable and is not refunded if the application is refused, and the current figure is published on the UK immigration fees guide. A child who turns 18 before the application is decided is invited to a citizenship ceremony before the certificate is issued.
Frequently asked questions
Only where a parent was a British citizen otherwise than by descent at the time of the birth, under section 2 of the British Nationality Act 1981. Where the parent is British by descent, the child has no automatic claim and must apply to register.
Often, yes, but through registration rather than automatic acquisition. Two entitlement routes may apply: section 3(5), where the family has lived in the UK for three years, and section 3(2), where a grandparent was British otherwise than by descent. Where neither fits, registration may be possible at the Home Secretary’s discretion under section 3(1).
It depends on the route. Section 3(5) requires the child and both parents to have lived in the UK for the three years before the application. Section 3(2) does not require the child to live in the UK, because it depends on the parent’s earlier residence and the grandparent link.
On the section 3(5) and section 3(2) routes, the relevant family members must not have been absent from the UK for more than 270 days during the relevant three-year period. On the section 3(5) route there is no discretion to allow longer absences.
Yes, where the child is aged 10 or over at the date of application. This is a statutory requirement and covers any criminal record, immigration breaches and similar matters.
On the section 3(5) route, the consent of both parents is required and cannot be waived, except where a parent has died.
