What is the difference between sealing and expunging?

Sealing means a criminal arrest record is closed to public inquires, and its existence is allowed to be divulged only in limited circumstances (see the page on sealing). Sealing is available to a charge that received a withhold of adjudication for most charges. Expungement means the criminal history record is physically destroyed, and can't be accessed. However, an individual who has a criminal record expunged must still reveal that record in certain circumstances (see the page on expungement). Expungement is not available if a charge resulted in a withhold of adjudication.
