In Colorado, sealing of records refers to adult cases and expunging records refers to juvenile cases. The rules as to who is eligible differ, but when successful the result is the same. You can honestly say that the case does not exist. Only certain cases are eligible and the law changes from time to time. There are also exceptions to the general rules of the effect of sealing or expunging records, such as for certain security clearances.
