A dominant estate (or dominant premises or dominant tenement) is the parcel of real property that has an easement over another piece of property (the servient estate). The type of easement involved may be an appurtenant easement that benefits another parcel of land, or an easement appurtenant, that benefits a person or entity. The easement may also be an affirmative easement, that permits a person to do something on the servient estate, or a negative easement that allows the holder of the easement to restrict activity on the servient estate. Estate is a common law concept.
