A right over a piece of land for the benefit of another piece of land, such as a right of way or a right to use services running under the land is called an “easement”. The land which benefits from an easement is called the “dominant tenement” or “dominant land” and the land which is subject to the easement is the “servient tenement” or “servient land”. There are several ways in which an easement can be created and once it exists then subject to certain exceptions, it exists for all time for the benefit of the dominant land.
