United Kingdom - Passport & Nationality - British Citizenship (British Overseas Territory - Mother) Post 82
A person born after 31 December 1982 to a mother who was born in a British Overseas Territory can normally rely on the reclassification rules enacted in recent years that allowed British Overseas Territory Citizens (or BOTCs) - by birth or by descent from a mother - to become full British citizens. If the applicant was born out of wedlock, it will complicate - but not invalidate - the process.
