General, or common occupancy of land. As regards land, the doctrine of occupancy was formerly of some importance. If A. granted land to B. during the life of C., and B. died before C., then there was no one entitled to the land, because A. had parted with his right during C's life, and B.'s estate had determined with his own death; therefore, any one might enter on the land and retain possession during the remainder of C.'s life. A person so entering was called an "occupant," because his title is by his first occupation," (Co. Litt. 41b,) or, more commonly, a "general occupant," because any one might enter in this (As to general occupancy in copyholds, see Elt. Copyh. 40.) This doctrine of general or common occupancy was abolished by the Statute of Frauds, (Stat. 29 Car. II. c. 3, 212,) under which, and subsequent statutes, (Stats. 14 Geo. II. c. 20, § 9; and 1 Vict. c. 26, 22 3, 6,) a tenant pur auter vie may dispose of his interest by will, and in default of such disposition it forms part of his personal estate. manner. 4. Special occupancy. If A. grants land to B. and his heirs during the life of C., and B. dies before C., B.'s heir may enter and hold possession, and in such case he is called a "special occupant," having a special right of occupation by the terms of the grant. (2 BI. Com. 258; 1 Steph. Com. 448; Wms. Real Prop. 20.) Blackstone includes rights of water, air, &c., emblements, copyright, and patents among things which are acquired by occupancy. 2 Com. 402 et seq. See the respective titles.
