Summary: Free Self Help info on how to get a conviction expunged in Illinois.
In Illinois, an individual who has been arrested, charged, or convicted of a criminal or traffic court offense may apply for either sealing of the records or for an expungement of the records. Specifically, Section 5.2 of the Criminal Identification Act (20 ILCS 2630/5.2) allows qualifying arrests, supervisions and convictions to be either ex- punged or sealed.
If you want information on how to do an expungement yourself, or how the expungement process works, the best starting Place is the 2012 Guide to How to Clear Your Criminal Record in Illinois from the Office of the State Appellate Defender.
