British Citizenship for Adopted Children: Rules and Process
Adoption and British citizenship intersect in complex ways. Whether an adopted child is British depends on where the adoption took place, whether the adopting parent is British, and whether the adoption is recognised under UK law.

In short
- UK adoption by a British citizen automatically makes the child British.
- Hague Convention intercountry adoptions may confer automatic citizenship.
- Non-Hague overseas adoptions may require registration or re-adoption in the UK.
- Intercountry adoption is heavily regulated and requires UK agency involvement.
Children adopted by British citizens can acquire British citizenship, but the process depends on the type of adoption. UK adoptions automatically confer citizenship. Intercountry adoptions under the Hague Convention may also confer automatic citizenship. Other overseas adoptions may require registration.
Adoption in the UK
If a child is adopted in the UK through a UK court adoption order, and at least one adopter is a British citizen on the date the order is made, the child becomes a British citizen from that date under section 1(5) of the British Nationality Act 1981. No separate citizenship application is needed.
The child can then apply for a British passport. You will need the adoption order and the adopting parent's proof of citizenship.
This applies to all UK adoptions, including adoptions by step-parents, relatives, and unrelated adopters, as long as the adoption is made through the courts.
Hague Convention Intercountry Adoptions
The Hague Convention on Intercountry Adoption sets a framework for adoptions between signatory countries; GOV.UK covers the UK side on its adoption pages. Where:
- The adoption takes place in a Hague Convention country
- It follows the Hague Convention procedures
- At least one adopting parent is a British citizen and habitually resident in the UK
the child becomes a British citizen from the date of the adoption under section 1(5A) of the British Nationality Act 1981. The requirement about the adopter being habitually resident in the UK or a qualifying territory is part of the section, not an optional extra, and the position also depends on when the adoption took effect.
Non-Hague Intercountry Adoptions
Adoptions from countries that are not Hague Convention signatories are more complex. The adoption may not be automatically recognised in the UK. In this case, you may need to:
- Re-adopt in the UK: Apply for a UK adoption order through the courts. Once granted, the child becomes British.
- Register the child as British: If the adoption is recognised by the UK, you can apply to register the child as a British citizen.
- Apply for an adoption visa: To bring the child to the UK before the UK adoption is finalised.
Which of these applies turns on the details of the adoption and on the country it took place in. This is family law as well as immigration law, so a solicitor is the right source: see our guide to solicitor costs.
The Intercountry Adoption Process
If you wish to adopt a child from abroad, you must follow the UK's regulated process:
- Contact your local authority or a registered adoption agency
- Complete an assessment (home study) — this takes several months
- Receive approval from the adoption panel
- Your application goes to the Department for Education, or the relevant UK Central Authority, which checks it against the eligibility criteria, issues the certificate of eligibility, and forwards the application to the overseas authority. The Department for Education charges a non-refundable fee of £2,500 for this, which does not cover legalisation, notarisation or translation
- Visit the child in their country and confirm your commitment to the adoption
- Work with the authorities in the child's country to complete the adoption
- Apply for the child's entry clearance (visa) to come to the UK
An adoption arranged outside this process may not be recognised in the UK, which leaves the child's status unresolved on both the family law and the immigration side. Our guide to applying alone or with a solicitor covers what regulated advice involves.
Registration Routes
If the child is not automatically British, you can apply to register them as a British citizen. The main routes are:
- Section 3(1): A general discretion. While a person is a minor, the Home Secretary may register them as a British citizen. This is the route most often used for an adopted child who is not automatically British.
- Section 1(3): For a child born in the UK who was not British at birth, where a parent later becomes a British citizen or settled here. It does not apply to a child born outside the UK.
Registering a child as a British citizen costs £1,000. Applications ask for the child's documents, the adoption papers, and evidence of the adopting parent's citizenship. See our guide on citizenship for children for more details.
Next Steps
The first question is whether the adoption is recognised under UK law, because that decides whether the child is already British or needs to be registered. A Hague Convention adoption and a UK court adoption order are the two clear cases. See our citizenship application guide for the general process. For intercountry adoption planning, start with your local authority adoption service.

Questions and answers
Does adoption automatically make a child a British citizen?
It depends on where the adoption took place and the adopting parent's status. A child adopted in the UK by a British citizen becomes British automatically. For intercountry adoptions, the child may become British automatically if the adoption is recognised under UK law, or they may need to be registered.
What is a Hague Convention adoption?
A Hague Convention adoption is one that takes place between two countries that are both signatories to the Hague Convention on Intercountry Adoption. These adoptions are generally recognised in the UK, and the child may automatically acquire British citizenship if the adopting parent is British.
How do I bring my adopted child to the UK?
The process depends on whether the adoption is recognised under UK law. For Hague Convention adoptions, the child may be able to enter on a British passport. For non-Hague adoptions, you may need to apply for an intercountry adoption visa or re-adopt the child in the UK.
Can I adopt a child from abroad while living in the UK?
Yes, but intercountry adoption is heavily regulated. You must follow the UK's intercountry adoption process, which involves assessment by a UK adoption agency, approval from the Department for Education, and compliance with the laws of both the UK and the child's country of origin.
