Yes. In some counties its called an expungement; in other counties its called a redaction. Also, in some counties the district attorneys fight vigorously against it and in other counties, they have no problem with it at all. In some counties the district attorney only fights it when the person is still under supervision for the other charges.
We do many of these every year and we treat them like any other expungement. They are important when you are originally charged with very serious felonies, but later only convicted of misdemeanors or summaries. You don't want an employer or a school to see felonies when you were never convicted of any felonies.
