Which term is used for a property right that may be revoked and is not classified as an easement?

The term that describes a property right that can be revoked and is not classified as an easement is a license. A license grants permission for someone to do something on another person's property, such as enter or perform an activity, without transferring any ownership interest in the property itself. Since licenses can be revoked at any time by the property owner, they are inherently temporary and not permanent rights like easements.

In contrast, easements provide a right to use someone else's property for a specific purpose and are generally more durable—that is, they cannot be easily revoked as they are often attached to the property itself. An encroachment refers to a situation where one property owner extends their use onto neighboring property on a permanent basis and does not fit the criteria of a revocable right. A prescriptive easement involves gaining a right through continuous and open use of property over time, which typically results in a more permanent interest in the property, unlike the revocable nature of a license.
