What type of ownership gives two or more owners equal, undivided interest with the right of survivorship?

JOINT TENANCY: Co-ownership where owners hold equal, undivided interests WITH the RIGHT OF SURVIVORSHIP — when one owner dies, their interest passes automatically to the surviving joint tenant(s), bypassing probate. THE FOUR UNITIES required (PITT): Possession (equal right to possess the whole); Interest (equal ownership shares); Time (acquired at the same time); Title (same deed/instrument); CONTRAST — TENANCY IN COMMON: Owners can have unequal shares, acquired at different times, with NO right of survivorship (a deceased owner's share passes to their heirs/estate); SEVERALTY: Ownership by one person alone; TENANCY BY THE ENTIRETY: A form for married couples in some states (survivorship plus additional protections); the right of survivorship is the defining feature of joint tenancy and a heavily tested concept on the national real estate exam.
