British Citizenship Through An Unmarried British Father

For many people, having a British father does not necessarily mean that they automatically became a British citizen at birth. Historically, British nationality law treated children differently depending on whether their parents were married.

This distinction particularly affected people born before 1 July 2006 to British fathers who were not married to their mothers. In certain circumstances, those who missed out on British citizenship because of these historic rules may now be entitled to register as British citizens using Form UKF.
