Right of survivorship describes what happens to a deceased co‑owner’s share in jointly held property: on death it passes automatically to the surviving co‑owner(s), outside the deceased’s estate and generally regardless of any will. In England & Wales and Northern Ireland, it is a core incident of a beneficial joint tenancy in land or other assets (for example, joint bank accounts and joint shareholdings). The deceased’s interest is extinguished and the survivor(s) become solely entitled. Severance of a joint tenancy (for example, by notice or mutual agreement) removes the right of survivorship and converts it into a tenancy in common. In Scotland, a similar effect is often achieved by a special destination (e.g. “to A and B and the survivor of them”), rather than by the same joint tenancy terminology. In Ireland, as in England & Wales, survivorship is an incident of a joint tenancy. The right of survivorship is significant in succession planning, co‑ownership disputes, insolvency and family law, particularly when considering whether an interest can be disposed of by will, claimed by heirs, or attacked by creditors.
