Final answer:
An easement is a right granted to a person that allows them to use someone else's land for a specific purpose, without creating an encumbrance on the land.
Step-by-step explanation:
The right described in the question is an easement. An easement is a right granted to a person that allows them to use someone else's land for a specific purpose, without creating an encumbrance on the land. It is a legal right that can either be granted by the landowner voluntarily or imposed by a court.
For example, if a landowner grants their neighbor the right to use a path on their property to access a lake, it is an easement. The neighbor can use the path without owning or selling the land, and it doesn't affect the landowner's ownership rights.
