"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.
