A record joint owner of an interest in real estate may use the provisions of this chapter to title the interest in a transfer-on-death form; provided, however, that title to the interest shall vest in the designated grantee beneficiary or beneficiaries only if the record joint owner is the last to die of all of the record joint owners of the interest. A deed in a transfer-on-death form shall not sever a joint tenancy.
