[1] In the Court of Common Pleas the Custos Brevium served as Chief Clerk, in charge of the officials that supported the Justices of the Common Pleas in their business.
[2] In practice the position was a royal favour, and the actual clerking was done by the Custos Brevium's Deputy.
The office of Custos Brevium of the King's Bench was combined with the Clerk of the Treasury and Clerk of the Warrants by the 17th century, and there is enough evidence to suggest this had probably occurred by the middle of the 15th century.
[3] In the reign of Edward IV, the post was held by John Fogge.
The second, third and fourth Earls occupied the position, which had been attached to the title, and which typically brought in £1000 annually.
