A personal, revocable, nonassignable right to use the property of another is called a(n)

The concept being described is a license, which is a personal right granted by one party to another that allows the latter to use the property of the former under specific conditions. This right is characterized by being revocable, meaning the property owner can terminate it at any time. Additionally, a license is nonassignable, meaning the licensee cannot transfer this right to someone else, which further distinguishes it from other property rights.

For example, consider a scenario where a homeowner gives a neighbor permission to use their driveway for parking for a limited time. This permission constitutes a license, as it allows the neighbor to benefit from the use of the property but does not convey any legal interest in the property itself. Because the homeowner retains full control, they can revoke this license whenever they choose.

In contrast, easements grant a more enduring right to use the land of another, typically for a specific function, and are assignable. Titles refer to the legal ownership of property, and encroachments involve unauthorized intrusion onto someone else's property, neither of which matches the definition of a license.
