What type of easement involves two separate properties with different owners?

An appurtenant easement involves two distinct properties owned by different parties, where one property benefits from the easement while the other property is burdened by it. This type of easement is typically established to allow access or use of a portion of the burdened property for the benefit of the other property, known as the dominant estate.

For example, if there are two neighboring parcels of land and one owner requires a pathway to access their property that runs through the other owner's land, the easement creates a legal right for the first owner to use a specific part of the second owner's land. This relationship remains attached to the properties themselves, meaning if the properties are sold, the easement persists with them.

In contrast, an easement in gross is not tied to any particular piece of land but is attached to an individual or entity, usually allowing for a specific use of someone else's land without a dominant estate. A temporary easement is limited to a specific duration and conditions, typically for construction or similar purposes, while an exclusive easement grants specific rights to one party to the exclusion of others, but it doesn't necessarily involve two separate properties in the same way that an appurtenant easement does.
