What Is Considered a Juvenile Crime in Massachusetts?

In Massachusetts, a juvenile crime is any criminal offense committed by someone between the ages of 12 and 18. These cases are usually handled in Juvenile Court under M.G.L. c. 119, which emphasizes rehabilitation over punishment. However, for serious charges, the state may move to try the juvenile as an adult—exposing them to the same penalties adults face.

Juvenile offenses can range from minor school-related incidents to serious felonies. A conviction can affect college admissions, financial aid eligibility, and future job opportunities. That’s why early and skilled legal representation is essential.

At the Law Office of Matthew W. Peterson, we represent minors facing a wide variety of juvenile charges. Common cases include:

Each case requires a tailored strategy. We investigate every detail, question law enforcement procedures, and look for alternatives to incarceration—such as diversion programs or community service.

Consequences of Juvenile Convictions in Massachusetts

While the juvenile justice system is focused on rehabilitation, convictions still carry serious consequences, including:

  • Juvenile Detention or Probation – Placement in the Department of Youth Services (DYS) or supervised probation.
  • Permanent Juvenile Record – Which can affect jobs, college applications, and financial aid.
  • Loss of Driver’s License – For certain drug or alcohol-related offenses.
  • Being Tried as an Adult – For serious crimes, exposing minors to adult prison sentences.
  • Collateral Consequences – Immigration issues, reputation damage, and family disruption.


Our goal is to minimize or eliminate these consequences whenever possible, helping your child move forward without lasting harm.

How We Defend Juvenile Crime Cases

Every juvenile case is unique, but our defense strategy typically involves:

  • Challenging the Evidence – Questioning police reports, witness credibility, and forensic results.
  • Protecting Constitutional Rights – Ensuring the child wasn’t unlawfully searched, interrogated without counsel, or coerced.
  • Pursuing Diversion Programs – Working to keep the case out of the formal court system through community-based resolutions.
  • Negotiating for Alternatives – Such as probation, counseling, or rehabilitation instead of detention.
  • Fighting for Dismissals or Reduced Charges – When the evidence is weak or improperly handled.
