New North Carolina Changes to Expungement Law Could allow thousands to expunge all records very soon! A North Carolina State Senate Bill would change the wait time for NC misdemeanor conviction expungements from 15 years to only 5 years. The same bill would change the wait time for low level felony convictions from 15 years to 10 years. Also people could have multiple dismissed cases expunged as well. If the bill passes the change would go into effect on December 1st of 2015.
