Okla. Stat. tit. 29, § 29-2-120: Lease

"Lease" is a contractual relationship by which one party obtains

a right to the possession and usage of a certain space, property, or

subsurface rights for a definite period of time. In the event a

person is permitted to come upon the land to perform some specific

act, such as hunting, that individual has no "lease" but only

"license" to do that act.
