Joint ownership
Ownership transfer may also be crafted within deeds to pass by demise, as where a property is held in concurrent estate such as "joint tenants with right of survivorship" (JTWROS) or "tenants by the entirety". In each case, the title to the property immediately and automatically vests in the named survivor(s) upon the death of the other tenant(s).
