The King's Remembrancer (or Queen's Remembrancer) is an ancient judicial post in the legal system of England and Wales. Since the Lord Chancellor no longer sits as a judge, the Remembrancer is the oldest judicial position in continual existence. The post was created in 1154 by King Henry II as the chief official in the Exchequer Court, whose purpose was "to put the Lord Treasurer and the Barons of Court in remembrance of such things as were to be called upon and dealt with for the benefit of the Crown",[This quote needs a citation] a primary duty being to keep records of the taxes, paid and unpaid.
The first King's Remembrancer was Richard of Ilchester, a senior servant of the Crown and later Bishop of Winchester. The King's Remembrancer continued to sit in the Court of the Exchequer until its abolition in 1882. The post of King's Remembrancer is held by the Senior Master of the King's Bench Division of the High Court.
