The right of survivorship means that when the first owner dies, their interest in the property is automatically absorbed so that the surviving owner now owns the whole property, see graphic. This is due to the operation of law and is independent of a will.
When the survivor dies, the property then passes according to their will, or if no will left, according to the intestacy rules. For people co-owning property as joint tenants, it is therefore important to review their situations and wills on a regular basis to ensure outcomes on death are what is wanted.
Joint tenancy and tenancy in common give different outcomes when an owner dies
Joint tenancy and tenancy in common are ways of owning property with others. Each works differently when an owner dies, see graphic below. This impacts who will inherit the deceased owner’s share. These graphics seek to highlight how each tenancy works.
In a joint tenancy, when one owner dies, the surviving one automatically owns the whole property. This happens independently of any will (and probate) because of the right of survivorship attaching to this tenancy type.
