Claiming British Citizenship by descent (grandparent) – also known as British Citizenship by double descent – is based on at least one of your grandparents being British. Double descent will require you to meet certain guidelines depending on when you and your grandparents were born.

Each application for British Citizenship by double descent will be assessed by UKVI on an individual basis. Since this is a complex procedure with a number of routes depending on your age, it is advisable to get the help of an immigration expert.

Your immigration lawyer will ensure you are eligible for British Citizenship by double descent. Your lawyer will advise you on the best route for you towards British Citizenship, working closely to support your family. We can also advise on your other options to apply for British Citizenship through descent, such as the UK Ancestry Visa.

How do I get British Citizenship by double descent?

If you were born after January 1, 1983

These are the following circumstances in which you can claim double descent if you were born after 1983:

  • Your (British-born) grandfather was in crown service at the time of your relevant parent’s birth;
  • You or a parent were born in a former British colony;
  • Your parent had a British-born mother, non-British father and was registered as a British citizen between February 2nd and December 31st, 1982.

If you were born before January 1st, 1983

You may be able to claim British Citizenship by double descent when:

  • You/your parent was born in a former British territory (this excludes main Commonwealth countries of 1949);
  • You/your parent was a registered British citizen;
  • Your parent was in crown service when you were born;
  • Your parents were married before 1949 and your paternal grandfather was born in Britain;
  • Your maternal grandfather was born in the UK and you were born outside the EEA.

If you were born before January 1st, 1949

The most common cases of those born before 1949 claiming British Citizenship by descent (grandparent) include:

  • You and your parent were not in a Commonwealth country (must have been born before 1915);
  • You or your parent were born in a former British territory;
  • Your grandparent or parent was married to a British man before 1949.

Can I get a British passport if I had a British grandparent?

Only British citizens are able to apply for a British passport. Before you can begin this application, you must be registered or naturalized as a British citizen. If one or more of your grandparents was born in the UK, there may be some circumstances in which you could claim British Citizenship through them.
