Filing a Petition to Seal your record is likely the most appropriate avenue to take. I would highly advise you spend the $25 and obtain a copy of your CORI to see what is on it above and beyond what you believe it will tell. By no means assume you know everything that is on your CORI. Massachusetts does not charge to file a Petition to Seal. You may also want to think about contacting an experienced attorney to discuss your options. Best of luck.
How much an attorney would charge to seal your CORI depends in part on how old these charges are and whether they were charged as misdemeanors or felonies. There are two main ways to seal a CORI: wait until the charge was old enough to seal by way of a petition to the Commissioner of probation (5 years for misdemeanors, 10 years for felonies) or for charges that were non-convictions only, petition the court that issued the charges to seal the CORI. Petitioning the court is used when the charges are not old enough to be sealed via petition to the Commissioner of Probation. Court petitions can be denied if the judge doesn't feel the petitioner has satisfied the statutory tests for sealing. Court petitions require more work and preparation than petitions filed with the Commissioner of Probation, and therefore cost more. Contact an attorney who has experience in sealing records to determine your most effective course of action.
