In a mortgage of real estate, or any interest therein, the words "mortgage covenants" have the full force, meaning, and effect of the following words, and shall be applied and construed accordingly:
"The mortgagor covenants with the mortgagee and his heirs, assigns, and successors, that he is lawfully seized in fee simple of the granted premises; that they are free from all encumbrances; that the mortgagor has good right to sell and convey the same; and that he does warrant and will defend the same to the mortgagee and his heirs, assigns, and successors, forever, against the lawful claims and demands of all persons."
R.C. §5302.13
