What term is used for a privilege to enter onto another person's property that is nonpossessory?

The correct term for a privilege to enter onto another person's property that is nonpossessory is a license. A license grants an individual the right to use or enter someone else's property for a specific purpose, without transferring any ownership rights or establishing a permanent presence on the land. This agreement can be revocable, meaning the property owner can terminate the license at any time.

In contrast, a lease generally refers to an agreement that gives the tenant exclusive possession of a property for a specified duration in exchange for rent, which does convey a possessory interest. An easement, while also a nonpossessory right, signifies a more permanent legal right to use another's land for a particular purpose (like access or utility installation) and is typically recorded with property deeds. A right of way is a specific type of easement that allows passage over someone else's land and is similar in nature to an easement, but again, involves more permanence and specific legal stipulations compared to a license. Thus, a license is the most fitting choice for a temporary and revocable privilege to enter another’s property.
