A record relating to any case that is dismissed will be expunged upon dismissal. Tenn. Code Ann. § 37-1-153(f).
(Cannot link directly to statutes.)
Ineligible Category or Citation
If the case was dismissed after the successful completion of an informal adjustment, pretrial diversion, or judicial diversion, the record is ineligible to be sealed under this section. Tenn. Code Ann. § 37-1-153(f).
There is no procedure. The expungement should be automatic.
The order of expungement, the original delinquent petition, and the order of adjudication and disposition will be sealed and maintained by the clerk of the court in a locked file cabinet and kept separate from all other records. In courts that maintain a case management system capable of expunging a record and only allowing access to the system administrator, paper copies need not be maintained. Any person whose records are expunged will be restored to the status that the person occupied before arrest, citation, the filing of a juvenile petition, or referral. For more information on the effect, see Tenn. Code Ann. § 37-1-153(f).
The record should be expunged immediately following the dismissal of the case.
