An easement by necessity is specifically created when a property does not have any legal access to a public road or utility, making it essential for the owner to have the right to pass over another person's land to reach their own property. This type of easement is recognized in situations where the necessity of access is clear; it ensures that landlocked properties can maintain their utility and value.

This differs from other types of easements. An easement appurtenant involves a dominant and servient estate, where the benefit of the easement is tied to the land itself rather than a particular owner.
