A court clerk - in British English clerk to the court, or in American English clerk of the court - is an officer of the court whose responsibilities include maintaining the records of a court. Another duty is to swear in witnesses, jurors, and grand jurors. Traditionally, the clerk also was the custodian of the court's seal, which is used to authenticate copies of the court's orders, judgments and other records. In common law jurisdictions, the existence of the office of a clerk is one of the typical criteria distinguishing a court of record. In some jurisdictions, the court clerk is the one who reads the jury's verdict form to the court. The Court Clerk is the supervisor of the Court Officers in the Courtroom.
