Under our law if your case has been dismissed, found not guilty, retired, or the state didn't prosecute you, you can get your case dismissed and expunged off your record. Also, you can get your case expunged if you were given a special type of probation called judicial diversion.
Also, there's another mechanism for class A felonies to get your record expunged if you fall under certain guidelines such as five years after the probation is terminated. Learn more here.
