The Succession to the Crown Act 2013 (UK)

The Succession to the Crown Act 2013 (UK) removes three significant disqualifications from the Act of Settlement 1701 and Royal Marriages Act 1774. First, it ends the system of male primogeniture — that a son inherits the throne in preference to an elder sister. Birth order determines succession for persons born after 28 October 2012. Neither sex is preferenced.

A look at the birth order of Queen Victoria’s children provides a good example of the system of male primogeniture. Victoria, Princess Royal was the first of Queen Victoria and Prince Albert’s nine children. Though the Princess Royal was born first in 1840, she did not inherit the throne. Her younger brother and her parent’s second child, Albert Edward, born in November 1841 took precedence over her. He inherited the throne in 1901 as Edward VII. If Victoria and Albert had nine daughters (and no sons), the Princess Royal as the eldest child would have inherited but only as heir presumptive. 

Secondly, marrying a Roman Catholic no longer disqualifies a royal from the line of succession for marrying a Roman Catholic. Thirdly, the monarch’s consent to marriage is only required for the first six in the line of succession. This change to British law needed to become law in all States and one Territory in Australia (the Northern Territory).
