You might be a British citizen

In most cases you’ll be a British citizen ‘by descent’. You don’t need to register or naturalise. You can live in the UK and get a British passport.

You’re a citizen ‘by descent’ if all the following apply:

  • you were born outside of the UK
  • one or both of your parents were British citizens at the time of your birth

Your children won’t automatically become British citizens.

When you’re not a British citizen

You won’t be a British citizen ‘by descent’ through your father if all the following apply:

  • you were born before 1 July 2006
  • your parents weren’t married when you were born and haven’t married since
  • the country your father considered his permanent home when you were born distinguished between children of married and unmarried parents - check with the country

In this case, you might still be able to register as a British citizen.

Parent in crown service

You’ll be a British citizen ‘not by descent’ if, when you were born, one of your parents was a British citizen in Crown service, designated service or service of a European Community (EC) institution.

This means you can pass on your British citizenship to your children.

Your parent must have been recruited to their service in the UK or EC (if they were serving with an EC institution).

Children born on or after 21 May 2002 also qualify if their parent was recruited in a British overseas territories, except the sovereign base areas of Akrotiri and Dhekelia (in Cyprus).
