In order that the tax imposed in this part may be expeditiously collected, if, within six (6) months after the death of any decedent, resident or nonresident, an executor does not qualify or an administrator is not appointed in Tennessee at the instance of other persons interested in the estate, then the commissioner may apply to the proper court for the appointment of an administrator of such estate, and it shall be the duty of such court to make such appointment forthwith.
