United Kingdom - Passport & Nationality - British Citizenship by Double Descent (12(5)1948 PGF Colony Marriage)
Section 12(5) of the BNA confers Citizenship of the UK and Colonies to a mother who is married to a CUKC man before 01.01.1949 if the mother is a British Subject. It does not matter whether that man has the CUKC status by birth, descent, registration or naturalisation.
Further criteria are:
- The applicant is female
- The marriage of the parents must have taken place BEFORE 01.01.1949
- The applicant must have been born AFTER 01.01.1949
- The applicant must have had the Right of Abode*, attained through marriage before 01.01.1983 to a man who was a Citizen of the UK and Colonies
- The paternal grandfather was born in country classified as the UK & Colonies after 01.01.1949
- The mother must have been a British Subject
* The requirement here is that the woman was a Commonwealth Citizen on 01.01.1983. The excludes South African women because South Africa was not part of the Commonwealth on that date. However, Commonwealth citizenship could have passed by descent, so one needs to look at where the woman's father was born before this is ruled out.
This is a particularly rare instance of application of UK Nationality, and will require a Status Trace to validate the claim.
