Ariz. Admin. Code § 12-5-513
Except as otherwise provided by law or these rules and regulations, assignments may be for all or part of the lands covered by a lease or permit. An application for assignment by the lessee or permittee, together with an application for transfer and assumption of lease or permit shall be submitted upon forms furnished and approved by the Commissioner. The applications shall be accompanied by the required fees, together with the lease or permit being assigned. The application for such assignment and the application for transfer and assumption of a lease or permit shall be signed by the parties as provided in these rules and regulations and acknowledged before a notary public or other officer authorized to administer oaths. The Commissioner shall indicate on the application to assign and application for transfer and assumption of lease or permit his approval or disapproval of the application, which action shall be made of record by the Commissioner.
In the event the assignment is a partial assignment and only covers a part of the leased or permitted lands, the description of the lands being transferred must be by legal subdivision or by metes and bounds based on an actual survey upon which acreage can be determined, together with a map or such survey if required by the Commissioner; otherwise no approval to said assignment and assumption will be granted by the Commissioner. An assignment may be only for a divided or undivided interest.
No assignment shall be made without the consent of all parties of record in the State Land Department in writing who may have a lien or encumbrance upon the lessee's or permittee's interest in said lease or permit.
