United Kingdom - flag United Kingdom - Passport & Nationality - British Citizenship by Triple Descent (48-5(1)a)

This British nationality solution relies on a UK-born great grandfather. Solutions rarely pass even two generations, so this is one of only a handful of such potential registrations that occur by Triple Descent, where nationality can be passed down three generations. It arises in this rare set of circumstances:

  • Candidate born between 1 January 1949 and 31 December 1982;
  • Candidate born after the independence of a parent's country of birth;
  • A parent born in a former British Protectorate, Protected State, UK Mandated State or Trust Territory, including those countries where the British Crown exercised Extra Territorial Jurisdiction (or ETJ);
  • The parent's father born outside of the UK;
  • The parent's paternal grandfather born in the UK; AND
  • The candidate having the Right of Abode.

The Right of Abode typically comes from a UK-born grandparent. It can also be gained by woman if they were married to a British husband before 1983.

Where the claim comes down the paternal line (i.e. through the father's birth in one of these territories), then the candidate should already be British. If the claim comes down the maternal line (i.e. the mother's side of the family), or it involves an illegitimate birth, then the candidate must register as a British citizen first.

WhatPassport.com is a specialist UK Nationality and British Citizenship site offering an online search and assessment. Claims to hold a British Passport can be complex and the site offers a quick, simple search to give you the answers. While many people qualify for the UK Ancestry Visa based on holding a Commonwealth passport with a UK born grandmother or grandfather, we have found that if you have a grandparent born in the UK, or if your mother is British or your father is British, then there are several scenarios where you can claim British Nationality and the right to hold a British Passport. This stems from Britain’s collection of British Colonies, British Protectorates and British Protected States in the middle of last century and the Nationality rules concerning what are now the countries of the Commonwealth.
