This series consists of deeds of properties which the Crown had acquired from private individuals and which were stored in the Treasury of the Receipt of the Exchequer.
The records were originally part of E 40 but were removed to a separate series because they were mainly later in date than 1603. The series consists almost entirely of records of conveyances, but also includes some bonds and wills.
A large number of the deeds appear to be related to the Court of Wards and Liveries. There are a large number of grants of wardship and other deeds issued by that court, as well as several which appear to have been used as evidence there.
There are several deeds which are directly related to the Exchequer, and many involve large sums of money connected with the Exchequer.
