The Equality (Titles) Bill, known colloquially as the "Downton Law" and "Downton Abbey Law",[1] was a Bill of the Parliament of the United Kingdom introduced in 2013 that would have ended a measure of gender discrimination and allowed for equal succession of female heirs to hereditary titles and peerages.

The bill was dubbed the "Downton law" in reference to the British television drama Downton Abbey where the Earl's eldest daughter is unable to inherit the family seat because it can only be passed to a male heir.

Emma Manners, Duchess of Rutland, mother of the British fashion model, Lady Violet Manners, her eldest child, gave an interview to The Express, in which she stated that "[she was] delighted that the estate would be passed on to [her] son Charles, Marquess of Granby, instead of [her] first born Violet.

It is a responsibility and a responsibility I am glad that my daughter does not have to bear.”[8] An amendment to the bill that would exclude baronetcies from its scope has been opposed by David Roche, Roddy Llewellyn, and Nicholas Stuart Taylor of the Stuart Taylor Baronetcy as well as Lord Monson.

[9] A number of the bill's supporters have titles that are in danger of dying out, as their only heirs are female.
