The Cyclopedic Law Dictionary
Walter A. Shumaker and George Foster Longsdorf; ed. James C. Cahill · 1922
The condition which exists where a person seised of land which is subject to an easement, profit a prendre, or similar right, also becomes seised of the land to which the easement or other right is annexed. The term is usually applied to cases where the seisin is that of a tenant in fee simple, and is equally high or predurable in both pieces of land, so that the easement or other right is extinguished by the unity of seisin.
