"Expunged" is a term that many people misuse and misunderstand. If you want to know if the conviction for the DUI is still on your record, the answer is yes. The fact of the conviction and sentence can be found by anybody; it is a public record. You may be wanting to know if all of your obligations to the court are finished and whether or not the case is closed. A DUI in Arizona normally carries a punishment of more than a class and a day in jail: there is a fine, other fees, and probation. Probation can be supervised or unsupervised. If you were ordered to pay a fine and fees, and have not done so, you may find that there is a warrant out for you, or a judgment against you for the debt. If you do not have a copy of the paperwork from the court that recorded the details of your sentence, you can get a copy from the clerk of the court where you were convicted. If you were placed on probation (whether supervised or unsupervised) and your fines and fees were paid in full, and if the court received notification that you completed the class that you were required to attend, you can apply to "Set Aside" the judgment of conviction. The fact of the conviction would not disappear from the public record; it would simply be followed by the fact of the "set aside" if the judge grants your request. I recommend that you hire a lawyer who is experienced with the "set aside" process and with the court where you were convicted if you are interested in applying for this possibility, to maximize your chance of success. Good luck. If a lawyer represented you in the original matter, that same lawyer may be able and willing to answer your questions and to provide you with a copy of the judgment of conviction, as well as to represent you in any attempt to set the judgment aside.
