Subject to section 2721.16 of the Revised Code, whenever necessary or proper, a court of record may grant further relief based on a declaratory judgment or decree previously granted under this chapter. The application for the further relief shall be by a complaint filed in a court of record with jurisdiction to grant the further relief. If the application is sufficient, the court, on reasonable notice, shall require any adverse party whose rights have been adjudicated by the declaratory judgment or decree to show cause why the further relief should not be granted forthwith.
