Massachusetts sealing and expungement: how M.G.L. c. 276 §§100A-100U actually works after the 2018 Criminal Justice Reform Act

Massachusetts maintains two distinct frameworks for criminal record relief that operate on fundamentally different substantive principles. Sealing under M.G.L. c. 276 §§100A-100D restricts access to records but doesn't destroy them — the records continue to exist for law enforcement and certain other entities. Expungement under M.G.L. c. 276 §§100E-100U permanently destroys records, eliminating the criminal history "as if it never existed." The frameworks differ substantially in eligibility criteria, procedural requirements, and substantive effect. Most Massachusetts criminal record relief proceeds through sealing rather than expungement because expungement requirements are narrower, but the 2018 Criminal Justice Reform Act substantially expanded both frameworks.

The April 2018 Criminal Justice Reform Act represented the most substantial overhaul of Massachusetts criminal record relief in decades. The reform shortened sealing waiting periods from 5 to 3 years for misdemeanors and from 10 to 7 years for felonies. The reform created statutory expungement (under §§100E-100U) where previously expungement was only a judicially-crafted remedy in extraordinary cases. The reform also directed the Department of State Police to direct the FBI to seal or expunge fingerprint database records corresponding to sealed or expunged Massachusetts records, addressing the long-standing problem of fingerprint-based background checks defeating Massachusetts sealing/expungement. The 2018 changes substantially expanded both the accessibility of sealing and the availability of expungement.

The CORI (Criminal Offender Record Information) system is the backbone of Massachusetts criminal records administration. CORI reports include adult Massachusetts open cases, convictions, and non-conviction dispositions (acquittals, dismissed cases, nolle prossed cases, CWOFs). When records are sealed under §100A, they're removed from public CORI access but remain accessible to:

• Law enforcement
• Child protective agencies
• Federal government
• Federally-funded programs

When records are expunged under §§100E-100U, they're permanently destroyed and inaccessible even to most government entities.

This is how the Massachusetts framework actually works under M.G.L. c. 276 §§100A-100U post-2018 reforms, the distinction between sealing and expungement frameworks, the procedural sequences through the Massachusetts Probation Service, the specific grounds for expungement (time-based versus non-time-based), and the strategic considerations for Massachusetts residents seeking record relief.

The two frameworks distinguished

Understanding the difference between sealing and expungement is critical:

Sealing under §§100A-100D. Records are restricted from public access but continue to exist:

• Mass. Probation Service administers
• Most criminal justice agencies retain access
• Records still appear on internal databases
• Person can claim "no record" for most employment/housing/licensing
• Easier to obtain than expungement
• More widely available

Expungement under §§100E-100U. Records are permanently destroyed:

• More substantial substantive relief
• Records erased from all databases including law enforcement
• Records erased from FBI fingerprint database (post-July 2019 effective date)
• Person legally has "no record" in all contexts
• Much narrower eligibility criteria
• Only available in specific circumstances

The substantive effect difference is substantial. Sealed records can still be discovered through certain channels (private background checks using courthouse direct queries before the 2018 reform required courts to seal their records too). Expunged records cannot be discovered through any legitimate channel.

Sealing under §§100A-100C

The sealing framework is the most commonly used Massachusetts criminal record relief:

Administrative sealing under §100A (convictions)

The most accessible sealing pathway is administrative sealing of convictions:

Eligibility requirements:

• Misdemeanor conviction: 3 years from sentence completion (reduced from 5 years pre-2018)
• Felony conviction: 7 years from sentence completion (reduced from 10 years pre-2018)
• Sex offense conviction: 15 years from sentence completion
• No new convictions during waiting period
• Person not currently subject to sex offender registration (for some offenses)

Procedural framework:

• File petition with Massachusetts Probation Service (Commissioner of Probation)
• Submit by mail
• Free (no filing fees)
• No court hearing typically required
• Probation Service reviews and processes
• Decision letter mailed indicating sealed charges and date to resubmit for any charges not yet eligible

The administrative framework is designed for efficient processing of most conviction sealing cases.

Continuance Without a Finding (CWOF) sealing. Cases where defendant admitted to sufficient facts and received CWOF with probation:

• Can be sealed under §100A after waiting periods
• Sealing may also be available under §100C if "good cause" standard met (typically immediate sealing upon successful completion)

Sealing under §100C (non-convictions)

Non-conviction dispositions have separate sealing framework:

Categories covered:

• Not guilty verdicts
• Dismissed cases
• Nolle prosequi (prosecution declined to proceed)
• No probable cause findings
• No bill (grand jury declined to indict)

Mandatory sealing for not guilty verdicts. Per Commonwealth v. J.F., 491 Mass. 824 (2023), not guilty verdicts must be immediately sealed.

Discretionary sealing for other non-convictions. Court applies "substantial justice" standard. The 2018 reform expanded discretionary sealing to a broader class of non-convictions.

Court petition required. Unlike administrative sealing under §100A, §100C sealing requires court petition (not just Probation Service administrative process).

Sealing under §100B (juvenile)

Juvenile delinquency files have separate framework:

Eligibility: Juvenile records subject to sealing after appropriate waiting periods and conditions.

Procedural framework: Petition to court with juvenile-specific procedures.

Substantive effect of sealing

When records are sealed:

Access restricted to:

• Criminal justice agencies (police, courts, prosecutors, corrections)
• Child protective agencies (DCF for child welfare matters)
• Federal government (for security clearance and similar)
• Federally-funded programs (for specific authorized purposes)

Access denied to:

• Most private employers
• Landlords
• Schools (except certain authorized programs)
• General public
• Most background check companies

Right to deny record. After sealing, person can answer "no record" or "no" to questions about criminal history in most contexts. The right to deny is statutorily protected — employers asking about sealed records (and using them in employment decisions) violate Massachusetts law.

2018 reform: courts must seal their records too. Pre-2018, private background check companies could obtain unsealed court records directly. The 2018 reform requires courts to seal their records corresponding to sealed CORI records. When sealed record requests are made to courts, the response is "no record."

FBI fingerprint records. Per 2018 reform effective July 1, 2019, Massachusetts directs FBI to seal records in the Interstate Identification Index corresponding to sealed Massachusetts records. The provision addresses the historical workaround where fingerprint-based federal background checks revealed records sealed in Massachusetts.

Expungement under §§100E-100U

The expungement framework provides more substantial relief but with narrower eligibility:

Time-based expungement under §§100F-100J

For offenses before age 21:

Eligibility requirements:

• Offense committed before petitioner's 21st birthday
• Misdemeanor: 3 years since case completion
• Felony: 7 years since case completion
• No other criminal court appearances or dispositions (except minor motor vehicle offenses with maximum $50 fine)
• Not more than 2 records eligible for expungement (multiple charges from same incident count as single record)
• Offense not in excluded categories under §100I

Excluded offenses under §100I:

• Sex offenses
• OUI/DUI offenses
• Offenses against elderly or disabled persons
• Violations of restraining orders
• Certain firearms offenses
• Various other specifically excluded offenses

Procedural framework:

• Petition filed with Massachusetts Probation Service
• Probation Service screens petitions
• Eligible petitions forwarded to court
• Notice to District Attorney
• Non-evidentiary hearing before judge
• "Best interests of justice" standard applied
• DA may object; if objection, contested hearing
• If no objection, court decides based on interests of justice

Non-time-based expungement under §100K

For specific grounds regardless of age:

Eligible grounds:

• Stolen identity / unauthorized identity use. Records arising from theft of identity or unauthorized use of identity.
• Serious error in case. Records arising from misidentification or other serious procedural error.
• Offense no longer a crime (decriminalization). Records for offenses that have been decriminalized — like simple marijuana possession after Massachusetts cannabis decriminalization.

Standard: Clear and convincing evidence that case resulted from one of the specified grounds.

Marijuana decriminalization expungement. The marijuana decriminalization grounds have been substantially expanded by:

• Statutory framework under §100K¼
• Commonwealth v. K.W., 490 Mass. 619, 620 (2022) — supreme court ruling broadening marijuana expungement availability

Procedural framework:

• Petition to court
• Notice to DA
• Hearing if contested
• Clear and convincing evidence burden on petitioner
• Court grants expungement if grounds established

Substantive effect of expungement

Expungement under §§100E-100U is substantially more comprehensive than sealing:

Records destroyed. Per §100Q, records expunged under §§100F, 100G, 100H, or 100K "may not be inspected in any form and by any person." The records are permanently destroyed across:

• Court systems
• Probation databases
• Law enforcement databases
• Other government agencies

No record exists. After expungement, the person legally has no record of the expunged offense. Background checks return no information. The person can truthfully state they were never arrested or charged for the expunged offense.

FBI fingerprint records. Per 2018 reform effective July 1, 2019, Massachusetts directs FBI to expunge corresponding records in the Interstate Identification Index. The provision ensures expungement extends to federal fingerprint records.

Limited exceptions. Even expungement has some limited exceptions:

• Records may exist in non-Massachusetts databases that aren't subject to Massachusetts orders
• Federal immigration consequences may persist for non-citizens
• Records sometimes retained for specific authorized purposes

The 2018 Criminal Justice Reform Act changes

The April 2018 reform substantially changed both frameworks:

Shortened sealing waiting periods. Misdemeanor sealing: 5 years → 3 years. Felony sealing: 10 years → 7 years. The changes substantially expanded accessibility of sealing.

Created statutory expungement. Pre-2018, expungement was a "judicially-crafted" remedy only in extraordinary cases. The 2018 reform created statutory framework under §§100E-100U providing clear procedural framework and substantive grounds.

Employer prohibition. Per the 2018 reform, employers are prohibited from requesting information about sealed or expunged records. The provision provides enforceable protection beyond just the practical effect of restricted access.

Court records sealing. Pre-2018, private background check companies could obtain unsealed court records directly even after CORI sealing. The 2018 reform requires courts to seal their records too, eliminating the workaround.

FBI fingerprint coordination. The reform directed Department of State Police to direct FBI to seal/expunge fingerprint database records (effective July 1, 2019). The provision addresses the long-standing federal fingerprint database issue.

Marijuana decriminalization framework. The 2018 reform and subsequent legislation expanded marijuana expungement availability, recognizing that previously-criminalized conduct now legal shouldn't continue to burden individuals through criminal records.

The cumulative effect of 2018 reforms substantially expanded Massachusetts criminal record relief beyond the prior framework. Many people who would have been ineligible under prior law now qualify for sealing or expungement.

How Massachusetts compares to other state frameworks

The framework has distinctive features:

Compared to New Jersey expungement with Clean Slate provision: NJ has 10-year multi-conviction Clean Slate framework; Massachusetts has 3/7-year sealing without lifetime limits. Both states reformed substantially around 2018-2020.

Compared to Missouri expungement (post-2025): Missouri has shorter waiting periods (1 year misdemeanor, 3 year felony) but lifetime limits. Massachusetts has somewhat longer waiting periods (3/7 years) but no lifetime limit on number of sealings.

Compared to Michigan's Clean Slate with automatic set-aside: Michigan has automatic processing for qualifying convictions. Massachusetts requires petition for both sealing and expungement.

Compared to Indiana Second Chance Law: Indiana's 5-section framework requires petition. Both states have specific anti-discrimination provisions. Indiana has clearer one-shot framework; Massachusetts has more flexible repeat-application possibility.

Compared to Pennsylvania's Clean Slate: Pennsylvania has more developed automatic sealing for many records. Massachusetts remains petition-based for most relief.

Compared to North Carolina expungement: Both states have multi-statute frameworks. NC reduced misdemeanor wait to 3 years; Massachusetts also has 3 years. Both states have substantial categorical exclusions.

Compared to Georgia record restriction: Georgia uses "restriction" terminology. Both states distinguish between restriction/sealing (records exist with restricted access) and broader relief. Georgia has First Offender Act pre-conviction option not available in Massachusetts.

Distinctive Massachusetts features:

• Two separate frameworks (sealing and expungement) with different requirements
• Mass. Probation Service administrative processing (free, mail petition)
• Court records sealing under 2018 reform
• FBI fingerprint coordination (post-July 2019)
• Marijuana-specific expungement grounds (Commonwealth v. K.W. expansion)
• Best interests of justice standard for time-based expungement
• Clear and convincing evidence standard for non-time-based expungement
• No lifetime limit on number of sealings

Strategic considerations

For Massachusetts residents pursuing record relief:

Choose between sealing and expungement based on eligibility. Sealing is more widely available but provides less substantial relief. Expungement is narrower but more comprehensive. Most Massachusetts residents seeking record relief proceed through sealing.

Take advantage of post-2018 reduced waiting periods. Misdemeanor sealing requires only 3 years from sentence completion (down from 5). Felony sealing requires 7 years (down from 10). The reduced periods substantially expanded accessibility.

Use the free Mass. Probation Service administrative sealing. Administrative sealing under §100A is free, doesn't require court hearing, and processes most conviction cases efficiently. Mail the petition and wait for the decision letter.

Consider non-conviction sealing under §100C. Dismissed cases, acquittals, nolle prossed cases, and similar non-convictions can be sealed but may require court petition (vs. administrative sealing for convictions).

Pursue expungement if grounds exist. If your case fits non-time-based expungement grounds (stolen identity, serious error, decriminalized offense), pursue expungement rather than just sealing. The substantive relief is substantially more comprehensive.

Use time-based expungement for youthful offenses. Offenses committed before age 21 may qualify for time-based expungement after appropriate waiting periods. The youthful-offender expungement framework provides path to comprehensive relief for early-life mistakes.

Watch for marijuana decriminalization expungement. Marijuana-related convictions for conduct that is now legal may qualify for expungement under §100K. The Commonwealth v. K.W. decision and subsequent legislation expanded availability.

Verify CORI status before petitioning. Obtain your CORI before filing sealing/expungement petitions. The CORI shows what records exist and what needs to be addressed. Multiple charges from same incident count as single record for expungement purposes.

Engage counsel for complex cases. Simple administrative sealing under §100A may be handled pro se. Complex cases involving:

• Multiple charges across multiple jurisdictions
• Contested expungement
• Marijuana decriminalization expungement
• Stolen identity expungement

...benefit from professional representation. Massachusetts sealing/expungement attorneys typically charge $1,000-$5,000 depending on complexity.

Address all financial obligations. Sealing/expungement typically requires completion of all sentence components including financial obligations (fines, restitution, court costs). Verify all obligations are satisfied before filing.

Don't overlook the no-new-conviction requirement. Both sealing and expungement require no new convictions during the waiting period. Subsequent criminal involvement can defeat eligibility.

Address private background check companies separately. Even with sealing/expungement, private background check companies may have outdated records. Direct communication with these companies, providing copies of sealing/expungement orders, may be necessary.

Understand the federal exception. Massachusetts sealing/expungement is state-level relief. Federal background checks (FBI, immigration, federal employment) may not be affected, though the 2018 reform's FBI fingerprint coordination provides some federal benefit.

Use the no-record-statement protection. After sealing or expungement, you can truthfully say you have "no record" or "no" for the specific offense in most employment, housing, and licensing contexts. The 2018 reform's employer prohibition provides additional protection.

Plan for the processing timeline. Administrative sealing typically takes 4-8 weeks. Court-petitioned sealing or expungement can take 3-6 months or longer if contested.

Watch for the FBI fingerprint coordination. Post-2018 reforms direct FBI fingerprint database updates. For sensitive employment requiring federal fingerprint background checks (childcare, healthcare, financial services), the federal coordination provides important benefit.

For Massachusetts residents whose criminal records affect current opportunities, the post-2018 framework provides substantial pathways to record relief. The combination of expanded sealing accessibility (reduced waiting periods, court records sealing requirement, employer prohibition), statutory expungement availability (time-based for youthful offenses, non-time-based for specific grounds), and FBI fingerprint coordination creates substantial protection for individuals seeking to move past previous criminal involvement. The work for Massachusetts residents is in identifying the appropriate pathway (sealing vs. expungement), gathering required documentation, satisfying all sentence components including financial obligations, filing through the appropriate procedure (administrative or court), and verifying implementation across all relevant databases. For most Massachusetts residents with non-excluded offense histories, the framework provides meaningful relief that addresses the practical consequences of past convictions on employment, housing, professional licensing, and other opportunities.
