The Barons of the Exchequer, or barones scaccarii, were the judges of the English court known as the Exchequer of Pleas. The Barons consisted of a Chief Baron of the Exchequer and several puisne (inferior) barons. When Robert Shute was appointed second baron in June 1579 the patent declared "he shall be reputed and be of the same order, rank, estimation, dignity and pre-eminence to all intents and purposes as any puisne judge of either of the two other courts." The rise of commercial trade in Elizabethan England occasioned fraudulent application of the Quo minus writ. More taxation demanded staff at the exchequer to sift an increase in the case load causing more widespread litigation cases to come to the court. From the 1580s onwards the Barons of Exchequer were no longer held in such low regard, and more likely to be Serjeants-at-law before qualification. The Inns of Courts began to exclude solicitors, and held posts for judges and barons open equally to barristers. In 1591, Regulations reflected a case in which the Lord Keeper Egerton banned solicitors from seeking cases in the Exchequer.

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 in 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 on 16 December 1880.
