In Idaho, what is 'joint tenancy with right of survivorship' and what must be present to create it?

Explanation

Joint tenancy with right of survivorship requires the four unities: Time (acquired simultaneously), Title (same deed), Interest (equal shares), and Possession (equal right to possess). Upon a joint tenant's death, their share passes automatically to surviving joint tenants — outside of probate. In Idaho, the deed must expressly state 'joint tenancy' to create it.
