Listen to our BRITISH NATIONALITY WEBINAR where our two British nationality experts - Philip Gamble and Mishal Patel - discuss a family birth in South West Africa and its implications for claims to British nationality in the modern day.


South West Africa was a former German Protectorate up until 16 December 1920. Between 17 December 1920 and 30 May 1962, it was a South African Mandated Territory in which the Crown exercised Extra Territorial Jurisdiction (or ETJ). From 31 May 1962 up until 24 August 1990, it was regarded as a foreign territory administered by South Africa. From that point, Namibia (as it became known) was an independent Commonwealth country.

Walvis Bay was treated differently and effectively formed part of South Africa for British nationality purposes. From 1 March 1993, it formed part of modern-day Namibia.

We have found two British nationality solutions that arise from a family birth in South West Africa:

British Citizenship by Double Descent (48-5(1)a Namibia)

British Citizenship by Double Descent (UKM CBR pre 1983)


The most common routes to British nationality are as follows:

Born to a British Father

Born to a British Mother

UK-Born Paternal Grandfather

UK-Born Maternal Grandfather

UK-Born Grandmother


Ask Philip Gamble whether you (or your children) have a claim to British nationality.

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.
