A person who seeks to redeem the property shall deposit the redemption amount with the levying officer during the redemption period. If the person is a successor in interest of the judgment debtor, at the time of deposit the successor in interest must file with the levying officer either (1) a certified copy of a recorded conveyance, or (2) a copy of an assignment or any other evidence of the interest verified by an affidavit of the successor in interest or of a subscribing witness thereto. (CCP 729.060(a))
