A separate instrument of transfer shall be filed for each lease on a form approved by the Director or an exact reproduction of the front and back of such form. Any earlier editions of the current form are deemed obsolete and are unacceptable for filing. When transfers to the same person, association or corporation, involving more than 1 lease are filed at the same time for approval, 1 request for approval and 1 showing as to the qualifications of the transferee shall be sufficient.
