The Court of Exchequer was one of the senior courts of law in Ireland (one of the four royal courts of justice), and served as a mirror of the equivalent court in England, dealing with matters of equity. It was established before 1300 and for most of its existence has been based in Dublin.
It became notorious for inefficiency, and so many cases were heard by other courts (particularly the Court of Chancery) throughout the 1700s. By the mid-1800s it had overtaken the Court of King's Bench as the busiest law court.
On the passing of the Supreme Court of Judicature Act (Ireland) 1877, it was merged with the other Courts of common law and the Court of Chancery (Ireland), to become a division of the High Court of Justice in Ireland. It was finally abolished with a further reorganisation of the Court system in 1897.
Although these records are from proceedings in courts based in Dublin, your ancestors from all over Ireland may be contained within. Be prepared to inspect records, regardless of your family birth location.

Those taking cases to Exchequer tended to be land owners, merchants, business owners, professionals and the larger farmers as it was expensive for anyone else to attend court in Dublin.
