Register as a British citizen

4. Born before 1 July 2006 to a British father

You can register as a British citizen if you:

  • were born before 1 July 2006
  • would have become a British citizen automatically if your parents had been married
  • are of ‘good character’ - see the guidance to form UKF for details

Apply using form UKF. Read the guidance before you apply.

Read about the different fees for citizenship applications.

Your children won’t automatically become British if born outside the UK.

You may be able to apply for naturalisation instead if you’re already resident in the UK.
