Decide whether you can apply to the Commissioner of Probation
Under Massachusetts General Laws, c. 276, s. 100A, you may apply to the Commissioner of Probation to have your "record of criminal court appearances and dispositions in the commonwealth" sealed, using a form provided by the Commissioner.
Complete a Petition to Seal your CORI provided by the Commissioner.
Sealing of criminal records is offered as a matter of right for many criminal offenses, which means that they will not appear on the CORI report, and will not be held against you in job applications, college applications, rental decisions by landlords, or even the decisions of professional licensing boards.
File a Motion to Seal with the Court
If you do not meet the time requirements to file a Petition to Seal with the Commissioner of Probation, then a Motion to Seal an entry on your criminal record would have to be filed in the court where you received the record. A judge can order sealing on a case-by-case basis if you can demonstrate that there is a compelling state interest that outweighs the public's right to have access to your CORI.
Consult with an Attorney
Consult with an attorney regarding the court process required to get your CORI sealed if a Motion to Seal is to be filed. Typically most courts will require you to establish a preliminary showing that your motion should be allowed and then require you to post your motion with the court prior to a final hearing. At the final hearing, you would have to demonstrate that there is a compelling state interest that outweighs the public's right to have access to your CORI before a court would consider granting your motion.
