Which type of easement does not benefit a specific parcel of land?

An easement in gross is a type of easement that does not benefit a specific parcel of land. Instead, it is tied to a particular individual or entity, allowing them rights over a certain piece of land without the necessity of owning an adjoining property. This can be seen in situations such as utility companies having the right to install lines across someone else's property, which benefits the company rather than a specific parcel of land.

In contrast, an easement by necessity allows a property owner access to their land when it is otherwise landlocked, thereby benefiting a specific parcel. An easement appurtenant always benefits a dominant estate, which is a particular parcel of land that has a right to use an adjacent parcel, while the servient estate is the land subject to that easement. An easement by prescription involves a legal right to use someone else's land acquired through continuous and open use over a certain period, benefiting a specific use rather than an individual.

Thus, the defining characteristic of an easement in gross is its independence from any particular parcel of land, making it the correct answer in this scenario.
