Most states call it expungement. Oregon calls it a Motion to Set Aside, governed by ORS 137.225. The effect is similar: when the court grants your motion, your criminal record — the arrest, the charge, the conviction — is sealed from public view. It no longer appears in background checks, employer searches, or housing screenings. In most cases, you can legally state that it does not exist.
Oregon law does not physically destroy the record. Law enforcement agencies retain access, and certain licensing boards can still see sealed records. But for most practical purposes — jobs, housing, credit, and daily life — the record is gone.
There is also a Motion to Set Aside an Arrest (for cases that were dismissed, acquitted, or never prosecuted). This is separate from a conviction set aside and often eligible without a waiting period.
