Right of Survivorship

 The right of survivorship is an attribute of several types of joint ownership of property, most notably [wex:joint tenancy] and [wex:tenancy in common].  When jointly owned property includes a right of survivorship, the surviving owner automatically absorbs a dying owner's share of the property.  Thus if A and B jointly own a house with a right of survivorship, and B dies, A becomes the sole owner of the house, despite any contrary intent in B's will.
