The implied easement arises by inference of law when certain facts concerning the conveyance of land are found by the court. There are two general fact patterns: (1) prior to severance of land there exists a quasi-easement' for the benefit of one part of the land to the detriment of the other;
(2) after conveyance of part of a tract of land, the grantor or grantee has no access to land respectively retained or conveyed.
The easement arising from the former will be termed an "implied easement" while the latter will be referred to as a "way of necessity." Though both easements are implied, the two will be distinguished by the above terminology to facilitate discussion.
