If a person born before 1 January 1983 outside the UK and his/her mother was born in the UK or a former colony that person can acquire British citizenship by registration or obtain âRight of Abodeâ stamp in your passport.
Children born before 1983 can now acquire British citizenship by registration application to the Home Office.
British Citizenship may also acquire if one of the grandparent was born in the UK and either was born in a former colony.
Prior to the introduction of the British Nationality Act 1981 on 1 January 1983 it was only possible for British fathers to pass on their citizenship to children born outside the UK.
Therefore if you were born outside the UK prior to 1 January 1983 and your mother is/was British then you may be eligible to apply for registration as a British citizen.
There are still requirements for you to satisfy such as being of good character.
