What type of co-ownership includes the right of survivorship?

The type of co-ownership that includes the right of survivorship is Joint Tenancy. In a joint tenancy, each co-owner has an equal share of the property, and if one owner passes away, their interest automatically transfers to the surviving co-owners. This feature is what distinguishes joint tenancy from other forms of property ownership, such as tenancy in common, where there is no right of survivorship; instead, a deceased co-tenant's share would pass according to their will or state inheritance laws.

Joint tenancy also requires the four unities: unity of time, title, interest, and possession, which means that all co-owners must acquire their interest at the same time, through the same deed, with the same rights to the property, and have equal possession. This legal structure enforces the right of survivorship distinctly, emphasizing collective ownership and the seamless transfer of interest among owners upon death, which can facilitate estate planning and asset management. In contrast, other options mentioned do not provide for survivorship rights or operate under different legal principles.
