Ariz. Admin. Code § 12-5-509
All leases and permits shall be signed by the lessee or permittee as provided by these rules and regulations and by the Commissioner or his Deputy, with the seal of the Department affixed thereto. All leases and permits shall contain such provisions, covenants, conditions and restrictions as may be prescribed by the Commissioner, hereinafter more particularly set forth under each type of lease. The effective date of the lease will be the date of application upon open land, or such other subsequent date as the Commissioner may prescribe. Upon lands previously leased, the date following the expiration date of the lease shall be the effective date; provided, that where the lands under lease have been reclassified, the effective date of the lease shall bear the date of such reclassification, if no appeal from reclassification is taken or if the Commissioner's decision is upheld if so appealed, or such other subsequent date as the Commissioner may prescribe.
Upon approval of the application to lease or permit and an appraisal or fixing of the rental value thereof, a lease or permit in duplicate will be mailed to the lessee or permittee, which lease or permit shall be signed in duplicate by the lessee or the permittee in the manner prescribed by these rules and regulations. Insert sheets which, when required, described the land being leased or for which permit is issued are a part of the lease or permit and shall be signed in the same manner as the lease or permit. A statement of the rental due and the permit or lease issuance fee will accompany the transmittal of the lease or permit. Upon the lease and permit and insert sheets, when required, being signed, they are to be returned to the Commissioner with the rental payment and lease or permit issuance fee in accordance with the statement rendered. When the lease or permit and insert sheets, when required, are received by the Commissioner, the same will be executed by the Commissioner as above provided and entered upon the records of the Commissioner. After execution by the Commissioner, one copy of the lease or permit, including the insert sheets when required, will be returned to the lessee or permittee with a receipt for the payment of rental.
If the lease, permit and insert sheets, when required, are not executed by the lessee or permittee and returned to the Commissioner, together with the payment of the rental as indicated by the statement therefor forwarded with such instruments, within 60 days from the date of mailing by the Commissioner, the lease or permit will be declared to be null and void and of no force and effect, and the land will become open and available for leasing by other persons. Provided, however, that should the applicant object to the appraised rental value, he may appeal from said appraisement as provided by law and the rules and regulations of the Department to the Board of Appeals of the State Land Department without prejudice to his rights to the offered lease or permit.
