Files of certificates of having taken the sacrament of the Lord's Supper according to the Anglican rite to comply with the Corporations Act of 1661 and the Test Act of 1672 for the purpose of holding office in a municipal corporation or under the crown. The latter required the delivery of a certificate attesting the fact into a court, King's Bench being one of those specified.
Apart from one file of 1676-1677, the series begins only in 1728, and ends in 1828 when, as a result of 9 Geo IV c 17, receipt of the sacrament ceased to be a requirement for holding office.
The certificates give the name of the church at which the sacrament was received, the date, and the names of the recipient, the minister, churchwarden and two witnesses.
