An Easement is a right that the owner of an interest in one piece of land (see interest in land) enjoys over the land of another. As a matter of definition, no easement can exist where both interests are owned by the same person. A quasi-easement arises when an easement would patently exist, but for the fact that there is common ownership. Quasi-easements are important because under the rule in wheeldon v burrows (1879) they are capable of conversion into real easements when the benefited land is sold.
