More information on the new legislation:
What is "Expungement"?
Under the law effective April 6, 2023, "expunge" means "To destroy, delete, and erase a record as appropriate for the record's physical or electronic form or characteristic so that the record is permanently irretrievable." Ohio Revised Code § 2953.31(B)(2)(b).
What is "Sealing of Records"?
Convictions and non-convictions can be sealed or “hidden” from most background checks. Sealed electronic and paper records are filed in a separate, secured location. The records still exist but cannot be seen by most people."
There are caveats and exceptions so read the accompanying materials carefully.
