Order 13, Rule 9 of the Civil Procedure Code, 1908, outlines the process for returning documents admitted as evidence in a suit. Generally, documents can be retrieved once the suit or any appeal period has concluded. However, provisions exist for earlier return if a certified or ordinary copy is substituted and the original can be produced if needed. Sections 451 and 457 of the Criminal Procedure Code (CrPC), along with Chapter XXXIV, govern the disposal of property in criminal cases.
