Easements are nonpossessory interests in real property. More simply, an easement is the right to use another's property for a specific purpose. Rights-of-way are easements that specifically grant the holder the right to travel over another's property
An easement appurtenant is an easement that benefits one parcel of land, known as the dominant tenement, to the detriment of another parcel of land, known as the servient tenement.
Any substantial interference with a right of way is a nuisance in common law. The owner of the right (known as the “dominant” owner) can apply to court for an injunction and damages if the landowner (or “servient” owner) blocks it.
An implied easement may be created only when two parcels of land were at one time treated as a single tract, or owned by a common owner. Accordingly, easements appurtenant may arise by implication
An easement is implied by existing use if the easement is necessary for the use and enjoyment of one parcel of land, and the parties involved in dividing the tract into two parcels of land intended that the use continue after the division. An easement is implied by necessity when one parcel of land is sold, depriving the other parcel of access to a public road or utility.
