Massachusetts Sealing and Expungement Standards: Judicial Petitions, Case Law, and Federal Records

Massachusetts gives people three distinct paths to putting a criminal record behind them, and each path has its own statute, its own standard, and its own case law. Administrative sealing runs on waiting periods. Judicial sealing runs on a good cause showing to a judge. Expungement, the complete destruction of the record, runs on narrow eligibility rules and a strong presumption once those rules are met. This page sets out the standards that actually decide these petitions, who benefits most from each remedy, what a Massachusetts seal does and does not do to an FBI record, and which offenses the Legislature has placed beyond sealing entirely. The practical basics live on our companion page, Sealing and Expunging a Massachusetts Criminal Record.

Administrative Sealing Under M.G.L. c. 276, § 100A

Section 100A sealing is a matter of right, not discretion. A misdemeanor conviction seals three years after disposition or release from custody, whichever is later, and a felony seals after seven, provided there are no intervening convictions or incarceration in the waiting period. Most sex offenses require fifteen years and freedom from registration obligations. The petitioner files a form with the Commissioner of Probation, and once the criteria are met the Commissioner has no discretion to refuse. No judge is involved and no reasons need be given. For anyone whose waiting period has run, this is the simplest remedy in Massachusetts law.

Judicial Sealing Under Section 100C, Pon, and J.F.

Cases that ended without a conviction seal through the court under M.G.L. c. 276, § 100C, and the law here has moved decisively in the defendant’s favor. In Commonwealth v. J.F., 491 Mass. 824 (2023), the Supreme Judicial Court held that a case ending in a not guilty finding is subject to mandatory and immediate sealing, reversing decades of contrary practice. Acquittals, no bills, and findings of no probable cause no longer wait on a judge’s discretion.

Charges that were dismissed or nolle prossed seal on a judge’s discretionary finding that substantial justice would best be served. The controlling standard comes from Commonwealth v. Pon, 469 Mass. 296 (2014), which replaced the old constitutional test with a practical good cause inquiry. A judge weighs the particular disadvantages the record creates for the petitioner, evidence of rehabilitation, the circumstances at the time of the offense, the passage of time, and the nature and reasons for the disposition. A well-built petition speaks to each factor with specifics. A job posting that requires a clean check, a licensing application on hold, a denied apartment, and letters showing what the petitioner has done since carry far more weight than a bare request. Attorney Serpa prepares Pon petitions the way he prepares clerk-magistrate hearings, with documentation aimed at the factors the judge must weigh.

Expungement Destroys the Record

Expungement is the deeper remedy. It destroys the record at the DCJIS, the court, and Probation, and after it the Commonwealth answers every query, including queries from law enforcement, with no record found. Massachusetts offers two expungement paths, and they run on different standards. Confusing them is the most common drafting error in these petitions, so this page treats them separately.

Time-Based Expungement Under Sections 100E Through 100J

Time-based expungement reaches offenses committed before the petitioner’s twenty-first birthday. Three years must have passed since disposition or release for a misdemeanor and seven for a felony, the petitioner may hold no more than two expunged records in a lifetime, charges arising from a single incident count as one record, and there can be no subsequent cases. Section 100J excludes roughly twenty offense categories from this path, including assault and battery with a dangerous weapon, firearms offenses, restraining order violations, sex offenses, and operating under the influence. The petition goes to the Commissioner of Probation, the District Attorney receives notice, and the court decides in the best interests of justice.

Within those limits the law now leans hard toward the petitioner. Commonwealth v. K.W., 490 Mass. 619 (2022), gives the qualifying time-based petitioner a strong presumption in favor of expungement. A judge may deny relief only when a significant countervailing concern is raised, may not count the petitioner’s other criminal records against the petition, and must make detailed written findings to support any denial. The natural beneficiaries are former student defendants, whose cases almost always arose before twenty-one and whose graduate school, bar, and licensing applications are answered most cleanly by a record that no longer exists. Our student defense FAQs cover the application disclosure questions in detail.

For-Cause Expungement Under Section 100K

For-cause expungement has no age limit and no waiting period, and the burden runs the other way. The petitioner must prove by clear and convincing evidence that the record resulted from a qualifying ground. The grounds are specific. Someone else used the petitioner’s name or identity and the case belongs to that person. Fraud was perpetrated upon the court. Law enforcement, court employees, or witnesses committed demonstrable error. Or the conduct is no longer criminal, the ground that reaches old marijuana offenses after decriminalization. A Section 100K petition is won with proof rather than presumptions, and it should be built like a small trial, with police reports, court records, and identity documentation assembled before filing. Victims of identity theft should pair the petition with the evidence discussed on our identity fraud and financial crimes page, because the same proof that clears the name carries the expungement.

Noncitizens should take immigration advice before filing either kind of petition, because federal immigration law applies its own definition of conviction and does not always honor state record relief, as our immigration consequences page explains. Where an old plea was taken without the full statutory warning, withdrawing the plea under the SJC’s Chhieng decision may serve the client better than any record remedy.

What Can Never Be Sealed

The Legislature has placed a defined set of offenses beyond Section 100A sealing no matter how much time passes. Crimes against public justice under chapter 268 lead the list, including intimidation of a witness, perjury, and escape. State ethics and conflict of interest offenses under chapter 268A cannot be sealed, and neither can firearms licensing offenses under chapter 140, such as providing false information on a firearms identification card application. Certain sex offenses remain unsealable while the person is subject to registration, and Level 2 and Level 3 offenders face additional restrictions. One problem deserves emphasis. Witness intimidation is charged freely in Massachusetts domestic violence cases, often for nothing more than asking a complainant not to call police, and a conviction on that count follows the client forever. Resisting arrest, by contrast, became sealable under the 2018 reform. The lesson for pending cases is to fight the unsealable count hardest, because every other outcome can eventually be repaired and that one cannot.

Trades, Licenses, and Students

What a seal is worth depends on who is asking. Under M.G.L. c. 151B, employers may not ask about sealed cases and an applicant with a sealed record may lawfully answer that he has no record, which restores union apprenticeships, trade licenses, hoisting and electrical cards, and ordinary private employment to reach. State licensing boards are a harder audience, because many boards hold statutory access to sealed records and their applications ask questions that a seal does not erase, a problem covered in depth on our pages for licensed professionals and professional license consequences. Self-regulators like FINRA apply their own disclosure rules and do not always honor a state seal. Students face their own version of the question on graduate school, medical school, and bar applications, where the safest record is the one that was never created, as our student defense page explains. Expungement answers most of these problems more completely than sealing, because after expungement there is nothing for any of them to find.

FBI Rap Sheets and Federal Background Checks

A Massachusetts seal binds Massachusetts. The FBI keeps its own Identity History Summary built from fingerprint submissions, and a state seal does not reach into that database on its own. Since July 1, 2019, the DCJIS has been required by M.G.L. c. 23C, § 36 and c. 276, § 100T to transmit sealing and expungement orders to the FBI and request that federal records be updated, and a person can push the process by sending certified court documentation to the FBI directly. FBI rap sheets also frequently show an arrest with no disposition at all, which reads worse than the truth, and correcting that omission is often worth doing on its own. Careers that run on federal fingerprint checks, including federal employment, defense contracting, banking positions subject to federal rules, TSA and immigration screening, and any job requiring a security clearance, may see a sealed Massachusetts case, and the clearance forms instruct applicants to disclose matters even when they are sealed. For clients headed toward those careers, the defense goal in the underlying case is to win outright rather than rely on a later seal, and where a record exists, expungement and a corrected FBI file are the strongest combination available.

The Best Record Is the One Never Created

Every remedy on this page repairs damage after the fact, and every one of them is second best to preventing the record. A clerk-magistrate hearing won means no complaint, no arraignment, and no CORI entry to seal, and nothing for the FBI to collect. A dismissal negotiated before arraignment does the same. That is why Serpa Law Office treats the earliest stage of every case as the record protection stage, and why our results page counts complaints denied and cases dismissed before arraignment as the most valuable outcomes in criminal practice.
