An estate in lands or tenements granted to two or more persons, to hold in fee simple, fee-tail, for life, for years, or at will. 2 Bl. Comm. 180; 2 Crabb, Real Prop. 937. An estate acquired by two or more persons in the same land, by the same title, (not being a title by descent,) and at the same period; and without any limitation by words importing that they are to take in distinct shares. 1 Steph. Comm. 812. The most remarkable incident or consequence of this kind of estate is that it is subject to survivorship.
