Doesn joint tenancy always avoid probate?
No. Joint tenancy does not avoid probate upon the death of the last owner. For instance, if you and your spouse own your house as joint tenants and you die, the house passes to your spouse free of probate. However, when your spouse dies, or if you and your spouse die simultaneously, the property will be subject to probate because there is no surviving joint tenant. Had the house been placed in the living trust, there would not be probate at either death.
