In most cases, groping in Massachusetts is prosecuted as indecent assault and battery under Massachusetts law. Although many people think of groping as an embarrassing misunderstanding or isolated incident, prosecutors often treat it as a felony sex offense that can carry up to five years in state prison, mandatory sex offender registration, and other life-changing consequences.
If you have been accused of groping in Massachusetts, it is important to understand that the Commonwealth must prove specific legal elements beyond a reasonable doubt, including that the touching was intentional and legally indecent. This guide explains how Massachusetts law defines indecent assault and battery, the potential penalties, common defenses, the role of consent, and what to expect if you are under investigation or have already been charged.
"Groping" Is a Word You'll Never See in the Statute
The word “groping” doesn’t appear anywhere in Massachusetts law. What you call groping, prosecutors call indecent assault and battery under General Laws Chapter 265, Section 13H. The charge covers an unwanted, intentional touching of another person that the law considers “indecent” — meaning it involves areas commonly understood to be private, such as the breasts, buttocks, genital area, inner thighs, or abdomen. Touching over clothing still counts. A single, brief contact is enough.
This is where people get blindsided. You might think a charge that serious requires force, injury, or something prolonged. It doesn’t. Massachusetts courts have made clear that force and violence are not elements of the crime — the touching itself, however slight, can be the entire case against you. The question isn’t how hard or how long. The question is whether the contact was intentional, unwanted, and indecent by contemporary standards.
The Same Charge, Three Familiar Settings
People accused of groping in Massachusetts tend to come from a handful of everyday situations. The location changes; the charge does not.
- At a bar or nightclub. Crowded rooms, alcohol, a packed dance floor — these are the most common settings for an indecent assault and battery arrest. An alleged grab on the dance floor, a hand on someone as you squeeze past, a touch that you remember one way and the other person remembers another. Bars often have security cameras, and clubs frequently call the police immediately. High-profile arrests in Boston bars have all carried the same Section 13H felony charge that an ordinary person would face.
- At work. A touch a coworker found offensive can become a criminal complaint, not just an HR matter. People assume workplace touching stays internal — a meeting with human resources, maybe a write-up. It doesn’t always. A complaint to police turns the same conduct into a felony sex charge, and an internal investigation running alongside the criminal case can create real risks for anything you say.
- On public transit. Crowded subway cars, buses, and platforms generate these accusations regularly. Close quarters mean contact is sometimes unavoidable, and that’s exactly what makes these cases contested — the difference between an accidental brush in a packed train and an intentional indecent touching is the whole case. The MBTA Transit Police take these reports seriously and make arrests.
Why People Underestimate This Charge
Indecent assault and battery on a person 14 or older is a felony in Massachusetts. A conviction can mean up to five years in state prison, or up to two and a half years in a house of correction. Even with no prior record, jail time is a real possibility — at sentencing, the alleged victim typically gives a statement and often asks the court for incarceration.
The part that catches people most off guard comes after any sentence: mandatory sex offender registration. Indecent assault and battery is one of the offenses that triggers registration under Massachusetts law. That means classification by the Sex Offender Registry Board, and depending on your level, your name, photo, and offense can become publicly searchable.
Registration reaches into housing, employment, professional licensing, immigration status, and your standing in the community for years. A few seconds of alleged contact can reshape the rest of your life in ways the courtroom sentence alone never captures.
Accidental Contact Is Not the Same as a Crime
Not every touch is indecent, and not every accusation holds up. Because the charge requires an intentional and indecent touching that the other person did not consent to, genuinely accidental contact — the brush-up in a crowded room, the bump on a lurching train — is not the crime.
Massachusetts appellate courts have reversed convictions where the contact, viewed objectively, simply wasn’t indecent. Mistaken identity is common in chaotic, crowded settings. Memories distort, especially where alcohol is involved. These are real legal distinctions, and they are why the details of what actually happened matter enormously.
None of this means you should try to explain your way out of it on your own. The most damaging thing you can do after an accusation is talk — to police, to the other person, to coworkers, to anyone investigating. Statements meant to clear things up routinely become the strongest evidence against the person who made them. Say less, and get advice before you say anything at all.
