Prior to 1983 children born outside of the UK to British mothers but foreign fathers did not have a claim to British citizenship. That right was only passed through British fathers.
Last year (13 January 2010), the Borders, Citizenship and Immigration Act 2009 came into force which meant I was finally granted the right to claim British citzenship via my British mother. Incredibly, it was only “a right to register as a British citizen” and I would also have to pay £540 to claim my British citizenship! This was absolutely outrageous since anyone born in the same circumstances after 1983, or at anytime to a (married) UK father, could simply complete a passport application without the need to register and without any fee.
There was a public outcry (quite rightly) from myself and many others about this blatant discrimination. Consequently, the law was amended in November 2010 and the application fee (which had actually gone up to £550 during the year!) was removed.
However, we still have to register and are required to pay an administrative fee of £80 to cover the cost of a citizenship ceremony.
Registration and the citizenship ceremony are meant for those without a British parent.
