Claim British citizenship by double descent

There are provisions in law allowing a claim to British citizenship based on having a grandparent (and, in rare cases, a great grandparent) born in the UK. This is known as double descent.

Born after 1 January 1983 (Under 18)

There are special provisions in British nationality law for children under 18 that may make it possible for you to claim British nationality. It is important to take action and process your British citizenship application before a child turns 18. After they turn 18, several rights to British nationality fall away and can be lost forever.

Born after 1 January 1983 (18 and over)

An adult born outside of the UK after 1 January 1983 with a UK-born grandparent may have a claim to British citizenship by descent if:

  • They had a UK-born grandfather who was in Crown service at the time of the relevant parent’s birth
  • A parent:
    1. Had a UK-born mother
    2. Did not have a UK-born father
    3. Was registered as a British citizen between 2 February 1979 and 31 December 1982
  • You or a parent were born in a former British colony, subject to further criteria being met.

Born before 1 January 1983

Those born outside of the UK between 1 January 1949 and 31 December 1982 and who have a UK-born grandparent may be able to claim British citizenship in certain circumstances.

The following are the most common ones:

Born before 1 January 1949

Those born outside of the UK before 1949 and who have a UK-born grandparent may claim British citizenship in certain circumstances. These are also complex cases and each claim must be assessed on an individual basis.
