British citizenship by descent

British citizenship by descent is available to certain people born outside the UK to a British parent. In some cases it is automatic; in others, you may need to apply to register as a British citizen. Understanding these rules is not always straightforward — eligibility often depends on your parent’s citizenship status at the time of your birth, and the law has changed over the years. 

Our solicitors guide applicants through the process, ensuring eligibility is assessed correctly and evidence is presented clearly.

Eligibility requirements

You may qualify if:

• You were born outside the UK to a British parent.
• Your parent was a British citizen otherwise than by descent.
• You meet specific rules depending on your date of birth.
• In certain cases, you may be able to apply if your parent or grandparent served in the UK armed forces.

Application process

• Step 1 – Confirm eligibility and establish your parent’s status at the time of your birth.
   
• Step 2 – Gather evidence such as passports, birth certificates, and proof of parentage.
   
• Step 3 – Complete the online application and pay the relevant fee.
   
• Step 4 – Submit supporting documents and attend a biometric appointment if required.
