The right of a joint tenant, or other person, who has a joint interest in an estate, to take the whole estate upon the death of the other one.

Survivorship is particularly applied to those owning real property or other assets; such as, bank accounts or stocks, in "joint tenancy".

Joint tenancy includes the right of survivorship automatically; except that in some states in the United States, joint tenancy of a bank account creates only a presumption of survivorship which might be legally disproved by evidence that the joint tenancy was only for convenience.
