The penalties for indecent assault and battery depend primarily on the age of the alleged victim and the specific statute under which you are charged. A conviction involving a person 14 or older can carry up to 5 years in state prison. A conviction involving a child under 14 can result in up to 10 years in state prison, and aggravated cases may carry a mandatory minimum 10-year sentence. Regardless of the victim’s age, every conviction requires mandatory sex offender registration.
Being charged with a sex offense is frightening, and understanding your actual sentencing exposure is critical. This guide explains the penalties for indecent assault and battery in Massachusetts, including maximum prison sentences, mandatory minimum penalties, sex offender registration requirements, the differences between charges involving adults and children, and the factors that may affect sentencing under Massachusetts law.
Penalties For Indecent Assault and Battery on a Person 14 or Older (§ 13H)
When the complainant is 14 or older, the charge falls under G.L. c. 265, § 13H. The maximum penalty is five years in state prison, or up to two and a half years in a house of correction. Which court hears the case matters: the house of correction cap applies in District Court, while a Superior Court indictment opens the door to the longer state prison sentence.
The penalty climbs when the complainant is an elder (60 or older) or a person with a disability as defined by statute. In that situation, the maximum rises to ten years in state prison, with a second or subsequent offense reaching twenty years.
“Maximum,” though, is not “typical.” A 5-year cap does not mean a 5-year sentence. It marks the ceiling, not the expected outcome—a distinction that matters enormously when you’re trying to understand your real exposure.
Penalties For Indecent Assault and Battery on a Child Under 14 (§ 13B)
When the alleged victim is under 14, the charge is brought under G.L. c. 265, § 13B, and the exposure roughly doubles: up to ten years in state prison, or up to two and a half years in a house of correction. Like § 13H, this offense can be prosecuted in either District or Superior Court, and the forum shapes the realistic sentencing range. Two features of § 13B deserve attention.
- Consent is not a defense—the law treats a child under 14 as legally incapable of consenting to the conduct.
- Second, and critically for anyone weighing a plea, a § 13B prosecution cannot be continued without a finding or placed on file. A continuance without a finding, or CWOF, is a common disposition in Massachusetts that lets a defendant avoid a formal conviction by admitting to sufficient facts and completing a probationary period.
For most charges, it’s a valuable off-ramp. The § 13B statute closes that door by its own terms. The same is true of placing a case on file. That doesn’t mean a § 13B charge can’t be reduced, dismissed, or beaten at trial—it means the specific CWOF path isn’t available on the § 13B charge itself.
Aggravated and Repeat-Offender Penalties
Massachusetts law carves out harsher provisions when aggravating facts are present.
Under G.L. c. 265, § 13B½, an indecent assault and battery on a child under 14 becomes “aggravated” when it’s committed during the commission of certain enumerated felonies, or by a mandated reporter—a category that includes teachers, medical personnel, clergy, and others legally required to report child abuse.
The aggravated offense carries a ten-year mandatory minimum, with a maximum of life in state prison. “Mandatory minimum” is exactly what it sounds like: the sentence cannot be suspended or reduced below ten years, and there’s no probation, parole, work release, or good-conduct deduction until those ten years are served. Like § 13B, the aggravated offense cannot be continued without a finding or placed on file.
A separate provision, G.L. c. 265, § 13B¾, targets defendants with qualifying prior sex-offense convictions or adjudications who are again charged under § 13B. That provision carries a fifteen-year mandatory minimum and a maximum of life. This is the path the law now uses for repeat conduct involving children under 14.
These are the most severe corners of the statute. They apply only when specific facts are alleged and proven—which is precisely why the facts of your case, and how they’re charged, matter so much.
Mandatory Sex Offender Registration
This consequence reaches every conviction under §§ 13H, 13B, 13B½, and 13B¾. Indecent assault and battery is a registrable sex offense under the Sex Offender Registration and Notification Act, G.L. c. 6, §§ 178C–178Q. Conviction triggers an obligation to register with the Sex Offender Registry Board, which then classifies the person as a Level 1, 2, or 3 offender based on perceived risk of reoffense.
For many people, registration is the consequence with the longest reach. A sentence ends; the registry obligation can last decades. Classification level governs how much of your information becomes public, and a higher level can affect where you live and work. Anyone weighing the real cost of a conviction has to weigh registration alongside any jail or prison exposure—often it’s the more lasting penalty. Failure to register can result in penalties ranging from 2.5 to 5 years of imprisonment.
What First-Offense Sentencing Usually Looks Like
Statutory maximums describe the outer edge of what’s possible, not what happens in most cases. For a first offense under § 13H or the basic form of § 13B—where no mandatory minimum applies—incarceration at or near the maximum is the exception, not the rule.
First-time defendants in these cases frequently see dispositions involving probation, sex offender treatment, and conditions of supervision rather than the maximum term. Outcomes turn on the strength of the evidence, the specific allegations, the complainant’s age, your record, and the forum. A District Court case carries materially lower exposure than the same conduct indicted to Superior Court. None of this is a guarantee—it’s the realistic landscape, which is very different from the worst-case numbers in the statute.
What changes the picture sharply is a mandatory minimum. Once a charge falls under § 13B½ or § 13B¾, the statute removes the judge’s discretion to go below the floor. That’s why how a case is charged can matter as much as the underlying facts, and why early, strategic defense work can be decisive.
