A license is not an interest in land, but is a privilege to do something on the land of another person. In this case, the owner of land is granting a license to a person in order to allow him to use the land as a field for sporting events. A license can be terminated at any time by the person giving the license (unless a license agreement states otherwise) and will continue only as long as the person giving the license is the owner of the land. Upon the sale of the property, the license terminates unless the new owner agrees to continue the license.
