The Exchequer of Pleas or Court of Exchequer was a court that dealt with matters of equity, a set of legal principles based on natural law and common law in England and Wales. Originally part of the curia regis, or King's Council, the Exchequer of Pleas split from the curia during the 1190s, to sit as an independent, central court. The Court of Chancery's reputation for tardiness and expense resulted in much of its business transferring to the Exchequer. The Exchequer and Chancery, with similar jurisdictions, drew closer together over the years, until an argument was made during the 19th century that having two seemingly identical courts was unnecessary. As a result, the Exchequer lost its equity jurisdiction. With the Judicature Acts, the Exchequer was formally dissolved as a judicial body by an Order in Council of 16 December 1880.
