What type of interest is granted when someone allows a neighbor to store a camper in their yard for free?

The situation described involves a neighbor allowing someone to store a camper on their property without receiving any payment for that use. This arrangement does not transfer ownership or a permanent right to the camper's storage, but rather gives permission for the camper to be stored there temporarily. This type of agreement is classified as a license.

A license is a permission granted to use someone's property for a specific purpose. In this case, the neighbor is granting a license for the use of their yard for storing the camper. The key distinguishing factor is that it's a temporary allowance that can be revoked at any time by the property owner, unlike an easement which typically involves a more permanent right of use tied to the property itself.

Easement appurtenant and easement by necessity would involve more formal rights concerning the use of land and often require a dominant and servient estate relationship, which is not applicable here. An estate in land typically refers to ownership interests in property rather than permission to use it. Thus, the correct answer reflects the nature of permission that defines a license rather than a more permanent or ownership-related right.
