Since 1929, the island has been connected to the title of the tenement ', one of the 40 tenements whose owner had to keep a gun for the defence of the fief and, until forfeit in 2008, had a seat in the Chief Pleas. Originally, ', named after the medieval monastery whose site is close to it, was a parcel of land in north west Sark that was, at that time, owned by the Seigneur himself. When Sibyl Hathaway sold the island of Brecqhou to Angelo Clarke in 1929, she transferred that seat in the Chief Pleas to unrepresented Brecqhou. This was scant loss for her, as she owned more than one tenement and every member of the Chief Pleas was entitled to only one vote.
