The Office of the Chancellor is a mandatory office within the Diocesan Curia (canon 482.1). The Chancellor serves as the official notary of the diocese and authenticates the signature on official documents for the Bishop of the Diocese of Charleston. The Chancellor supervises the establishment, retention and access guidelines of records management.

This office also has under its purview the Diocesan Archives. The primary objective of the archives is to collect, preserve, and make available non-current diocesan records of permanent administrative, legal, fiscal, canonical and historic value. The archives also hold records of other institutions, agencies, personal papers, and publications documenting the history of the Roman Catholic Church within the diocesan boundaries.
