land patent(A land patent is a document recording the passing of a land title from the government, or other proprietor, to the patentee/grantee. OLGA P.)
statutory mortgage(Many jurisdictions permit specific assets to be mortgaged without transferring title to the assets to the mortgagee. Principally, statutory mortgages relate to land, registered aircraft and registered ships. Generally speaking, the mortgagee will have the same rights as they would have had under a traditional true legal mortgage, but the manner of enforcement is usually regulated by the statute.
