The courts will find an “easement by necessity” if two parcels are so situated that an easement over one is strictly necessary to the enjoyment of the other. The creation of this sort of easement requires that at one time, both parcels of land were either joined as one or were owned by the same owner. Prior use of the easement, however, is not required. The most common example of an easement by necessity is landlocked property, so that access to a public road can only be gained by having a right of way over an adjoining parcel of land. The legal theory is the landlocked parcel was accidentally created, and the owner forgot to include an easement appurtenant to reach the road.
