file

Definition from Nolo’s Plain-English Law Dictionary

A term commonly used to describe both the process of submitting a document to a court -- for example, "I filed my small claims case today" -- and to describe the physical location where these papers are kept. Traditionally, a court's case files were kept indefinitely in one or more cardboard folders. Today most files -- especially those for inactive cases -- are stored electronically.
