There are three statutes that lawyers use to clean/clear criminal records: RCW 10.97.060 Expungements, RCW 9.94A.640 Felony Vacate, and RCW9.96.060 Misdemeanor Vacate.
Most people think that they can make prior criminal records disappear. That is not often the case. However, there are steps that can be taken to amend records to reflect that charges were dismissed. Often such a change will satisfy an employer and under some circumstances make criminal records less visible if not eliminated.
