What type of easement is created for the benefit of the owner of the easement and does not benefit another parcel of real estate?

An easement in gross is designed specifically for the benefit of an individual or entity, rather than benefitting a specific parcel of land. This type of easement is often associated with utility companies, where the rights granted are for activities like placing power lines or pipelines across the property of another. The key characteristic of an easement in gross is that it does not serve a dominant estate; instead, it is directly linked to the person or entity that holds the easement.

In contrast, an easement by necessity arises when a property requires access to a landlocked area, benefiting one parcel by necessity for access purposes, and is thus tied to the real estate. A right of way easement typically refers to a specific type of easement that allows the holder to travel across another's property, often benefiting a particular property. Prescriptive easements involve a legal claim to use another's property based on continuous and open use over time, benefiting the easement holder in relation to a specific parcel.

Thus, the definition of an easement in gross being associated directly with a person or entity, rather than a piece of land, makes it the correct answer.
