Criminal expungement is the sealing of your criminal court records. The police, FBI, immigration officers and other public officials may still see sealed court files for certain purposes. Usually, people ask for an expungement when they have been denied a job, housing, or a professional license because of their criminal background.
For information on the process to have your record expunged, go to the Minnesota Judicial Branch Self-Help Center. The site includes the 5-minute video, “What is Criminal Expungement?”
The forms required to file for criminal expungement are on the court’s website. The Dakota County Attorney also has 
Guidelines for the Expungement of Criminal Records.
