British Citizenship for a Child Born Abroad
Expert legal guidance for families with children born outside the UK
If your child was born outside the United Kingdom, their right to British citizenship depends mainly on the citizenship and immigration status of the parents at the time of birth.
Children born abroad are not automatically British, even if one parent is. The correct route depends on whether citizenship can be passed on automatically or whether the child must be formally registered as a British citizen.
At Immigration Solicitors UK, our immigration solicitors help parents understand and secure their child’s British citizenship, guiding them from eligibility assessment to registration and passport applications.

Expert legal guidance for families with children born outside the UK
If your child was born outside the United Kingdom, their right to British citizenship depends mainly on the citizenship and immigration status of the parents at the time of birth.
Children born abroad are not automatically British, even if one parent is. The correct route depends on whether citizenship can be passed on automatically or whether the child must be formally registered as a British citizen.
At Immigration Solicitors UK, our immigration solicitors help parents understand and secure their child’s British citizenship, guiding them from eligibility assessment to registration and passport applications.
Understanding British Citizenship for Children Born Abroad
The key question is whether the child is automatically British or must apply for registration.
Under UK nationality law, British citizenship can be held “by descent” or “otherwise than by descent.”
- A British citizen otherwise than by descent (for example, someone born or naturalised in the UK) can automatically pass British citizenship to their children born abroad.
- A British citizen by descent (someone who inherited citizenship from their parents rather than being born or naturalised in the UK) normally cannot automatically pass citizenship to their child born overseas.
If the parent is British by descent, the child may need to register as a British citizen under Section 3(2) or Section 3(5) of the British Nationality Act 1981. This process is not automatic and is decided at the Home Office’s discretion.
Is My Child Automatically a British Citizen?
A child born abroad will automatically be a British citizen only if:
- At least one parent was a British citizen otherwise than by descent at the time of birth; or
- One parent was serving overseas in Crown service or the armed forces at the time of the child’s birth.
In those cases, you can apply directly for a British passport for the child, supported by the appropriate documents proving the parent’s British status and the family relationship.
If these conditions are not met, the child is not automatically British, and you must apply for registration.
Citizenship When the Parent Is British by Descent
If you are British by descent, you cannot usually pass citizenship automatically to a child born outside the UK.
In this situation, you will normally need to apply to register the child as a British citizen under Section 3(2) or Section 3(5), depending on your circumstances.
Section 3(2) – Parent’s Residence Before Birth
To qualify under Section 3(2):
- The parent must be a British citizen by descent.
- The parent must have lived in the UK for at least three continuous years before the child’s birth.
- Both the parent and child must have been physically present in the UK during that period.
- The application must be submitted before the child turns 18.
Section 3(5) – Child’s Residence After Birth
If the parent cannot meet the residence requirement before birth, Section 3(5) may apply.
To qualify:
- The child must have lived in the UK for three continuous years before the date of the application.
- During that time, the child must not have been outside the UK for more than 270 days.
- Both parents should be settled in the UK or have indefinite leave to remain at the time of application.
In both cases, applications are made to the Home Office, and supporting evidence must clearly demonstrate the relevant residence and citizenship history.
Other Circumstances
Children born abroad to parents in certain categories may automatically be British, such as:
- Children of parents working abroad in Crown service, diplomatic roles, or the armed forces.
- Children born through legal adoption by British citizens, provided the adoption complies with UK or Hague Convention standards.
If the British parent obtained their citizenship after the child’s birth, the child will not automatically be British but may later be registered.
Each case is unique, and early legal advice is strongly recommended.
Our immigration team offers full legal support for parents applying for their child’s British citizenship. We can:
- Assess eligibility under British nationality law and determine the correct section of the Act to apply under.
- Prepare and submit the Form MN1 application for registration.
- Gather and verify supporting evidence, including birth certificates, proof of residence, and British citizenship documents.
- Draft detailed legal representations explaining the family’s connection to the UK.
- Respond to Home Office enquiries and ensure the process runs smoothly from start to finish.
We also assist with complex or discretionary applications, including:
- Late submissions.
- Dual nationality and previous immigration issues.
- Cases involving Crown service or adoption.
With ISUK, your child’s case will be properly presented, documented, and compliant with all Home Office requirements.

Registration is the legal process through which a child who is not automatically British can be granted British citizenship.
Step 1: Determine Eligibility
You must first establish under which section of the British Nationality Act 1981 your child qualifies, usually Section 3(2) or 3(5).
Step 2: Complete Form MN1
Form MN1 is used to register children under 18 as British citizens. The form is available online and must be submitted with the correct Home Office fee and full supporting evidence.
Step 3: Provide Biometric Information
In most cases, the child’s biometric details (fingerprints and photograph) will be required at a UK Visa and Citizenship Application Services (UKVCAS) centre.
Step 4: Submit Supporting Documents
The Home Office will expect proof of:
- The child’s birth and parentage.
- The British parent’s citizenship and residence history.
- The family’s ties to the UK and intention to live here.
- The child’s lawful residence in the UK, if applicable.
Step 5: Wait for the Decision
The usual processing time is around six months, though complex or discretionary cases can take longer.
Once approved, the child will receive a Certificate of Registration as a British Citizen, after which you can apply for their British passport.
When preparing an application under Section 3(2) or 3(5), you’ll need to ensure that:
- The child is under 18 years old at the time of the application.
- The parent’s UK residence meets the three-year rule, with absences not exceeding 270 days.
- The family can show a genuine intention to live and settle in the UK.
- The application is supported by consistent, verifiable documentation.
Legal advice is essential to ensure the evidence is accurate and the correct section of the law is applied. Errors in timing or documentation are among the most common causes of refusal.

You will usually need to provide:
- The child’s full birth certificate showing both parents’ details.
- The parent’s British passport or naturalisation certificate.
- Proof of the parent’s UK residence, such as utility bills, tenancy agreements, or employment records.
- The child’s immigration and travel history.
- Marriage or civil partnership certificates, where applicable.
- Translations of any non-English documents certified by a qualified translator.
Before submission, every document must be complete, valid, and consistent. Inaccuracies, missing records, or expired evidence can delay or jeopardise the application.
At ISUK, we carefully review every application before submission to minimise delays and refusals.
Once your child becomes a British citizen, either automatically or through registration, they may apply for a British passport.
If Citizenship Is Automatic
If your child was born abroad to a British citizen otherwise than by descent, you can apply for a passport straightaway. You’ll need:
- The child’s birth certificate.
- Evidence of the British parent’s citizenship.
- Proof of the family’s connection to the UK.
If Citizenship Is by Registration
If citizenship was granted through registration, you must first receive the certificate of citizenship.
This certificate is required when applying for the child’s first British passport.
Need urgent help? Call:
Children aged 10 or over at the time of application must meet the good character requirement.
The Home Office will assess:
- Any criminal convictions, cautions, or warnings.
- Civil penalties, school expulsions, or dishonesty in immigration matters.
- Any history of false statements or omissions.
Parents must disclose all relevant information honestly. Failure to disclose could lead to refusal.
If there are any concerns, our solicitors can prepare detailed representations explaining the circumstances and demonstrating the child’s good character.
The Home Office aims to decide most applications within six months.
However, cases involving discretion (for example, under Section 3(2) or 3(5)) may take longer.
Providing complete documentation and following the correct procedure helps avoid unnecessary delays.
Our firm monitors each stage of the process and keeps you informed of progress throughout.

The correct form to register a child born abroad is Form MN1.

Applications are now submitted online, with documents uploaded or posted as directed.
The Home Office will confirm once the application is received and provide next steps for biometric enrolment

FAQ
Frequently Asked Questions
Can my child get British citizenship if only one parent is British?

Is there an age limit for registering a child?
Yes. The child must be under 18 years old on the date of registration.
Can I apply for a passport before citizenship is approved?
No. You can only apply for a British passport after receiving the child’s citizenship certificate.
Does the good character requirement apply to children?

Can adopted children be registered as British citizens?
Yes, provided the adoption is legally recognised under UK law and at least one adoptive parent is a British citizen.
