The clerks of the Petty Bag were responsible for enrolling the admission to and surrender of offices in Chancery of solicitors and other officials of the court.
The admission rolls bear the names of a wide range of officers, most, though not all, of whom were connected with the court of Chancery. Among them are the lord chancellor, the solicitor general, the lord high treasurer of England, and the master of the rolls.
Also included are the admissions of clerks of the Crown, clerks of the Petty Bag, masters in Chancery, clerks of bankrupts, clerks of the patents, serjeants at law, examiners in Chancery, keepers of records at the Rolls Chapel, and the librarian of the Cottonian Library.
The series also contains a commission to judges and masters in Chancery to hear Chancery causes in the absence of the commissioners of the great seal (1659), the enrolment of an order regulating the Six Clerks Office (1668), the articles of an agreement between the clerks of the Petty Bag and the clerk of the Patent Office (1676), and a record of the delivery of the great seal during the Interregnum.
