Custos Brevium
The Custos Brevium was an official in the English court system: in the Court of Common Pleas and Court of King's Bench. The post was abolished by Act of Parliament in 1830.
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. In practice the position was a royal favour, and the actual clerking was done by the Custos Brevium's Deputy.
The Custos Brevium of the King's Bench is a much more obscure figure because he was not appointed by the King. 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.

On the English Restoration of 1660, the remuneration was set at £80. The post was given to William Thursby, who held it to his death in 1701. During much of the 18th century, to 1776, the custos was from the Lee family of the Earl of Lichfield, Edward Lee, 1st Earl of Lichfield having been given the post in 1700. The second, third and fourth Earls occupied the position, which had been attached to the title, and which typically brought in £1000 annually.
The post was later held by Sir William Eden, 6th and 4th Baronet.
