Expungement (verb) – Erasure or removal, particularly from a record. Expungement means to wipe something out or to take it off a page, whether it is a person from a list, an entry from a record, or a memory from the mind. In law, it is often used to describe the official deletion of a record, such as the removal of an entry of arrest from a record of the arrests in a jurisdiction. Actions to expunge the record of a criminal charge or arrest may be formal and require a showing of error, or they may be informal, committed to the discretion of the court or other official.
