What is the difference between sealing and expunging my criminal record?

When a record is sealed, the public will not have access to it through the government databases. That means most employers will not have access to the information. However, city, county, state and federal government and agencies, including the police and military, have a legal right to access criminal history records even if they are sealed.  When a record is expunged, agencies that would have access to a sealed record will be able to know that criminal information has been expunged from the record, and would only have access to the record through a court order.
