A recorded mortgage if not discharged as provided in the preceding section, must be discharged upon the record by the officer having custody thereof, on the presentation to him of a certificate signed by the mortgagee, his personal representative or assigns, acknowledged or proved and certified as prescribed by the chapter on recording transfers, stating that the mortgage has been paid, satisfied or discharged: provided, that whenever a bank or the person appointed to liquidate the affairs of a bank as provided in section 26-908, has failed or neglected to issue a certificate showing the release, discharge or satisfaction of a real mortgage, the director of the department of finance, or his successor in office, may, upon the request of the owner, or any subsequent owner, or party in interest, issue to such party his certificate showing such mortgage to have been paid, discharged or satisfied even though the affairs of said bank have been completely liquidated.
