United Kingdom - flag United Kingdom - Passport & Nationality - British Citizenship by Double Descent (Sec12(6) Construance)

This is a complex - and rare - instance where British Nationality can be passed two generations - this time, from a UK-born Grandfather or Paternal Great Grandfather.

It requires the following set of circumstances:

  • The applicant was aged under 18 (or under 21, if before 01.01.1970)
  • The applicant's name was included in a parent's British Passport
  • The applicant has a male line descent back to the UK
  • The inclusion of their name in their parent's British passport took place between
  • 30.05.1962 and 30.05.1964 (in the case of a candidate born in South Africa, or descended from a South African born parent); OR
  • 18.11.1965 and 18.04.1980 (in the case of a candidate born in Rhodesia, or descended from a Rhodesian born parent)

The basis of the application is that this inclusion their parent's British Passport was incorrect, but it led the parent(s) to believe that their child was British and led them NOT to register their child as British during these key periods when they had the opportunity. In effective, this application is treated as an unresolved application, and the rules (and the ages) can be re-assessed as if it took place at the time the error occurred.

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.
