Massachusetts Criminal Defense Practice Areas

Serpa Law Office represents people in Massachusetts clerk-magistrate hearings, District Court and Boston Municipal Court cases, and Superior Court prosecutions. The practice includes OUI and motor vehicle offenses, domestic violence and restraining orders, drug and firearms charges, theft and financial crimes, sex offenses, and the consequences a criminal case may create for a record, professional license, education, or immigration status. This page organizes the firm’s criminal-defense resources by court stage, legal issue, charge, consequence, FAQ, and courthouse.

Attorney Joe Serpa has practiced Massachusetts criminal defense since 1995. In an eligible case, representation may begin at a private clerk-magistrate hearing before a complaint or arraignment. If the clerk-magistrate denies the application, that application produces no complaint, arraignment, or CORI entry. An arraigned case may later end in dismissal, but the court record remains unless it is sealed. The firm’s case results, dismissal results, and client reviews provide examples of the representation.

Students, licensed professionals, security-clearance holders, and noncitizens may face consequences outside the criminal sentence. Counsel should identify the exact disclosure rule, immigration issue, licensing standard, school process, and CORI effect before recommending a disposition. The sections below link directly to the detailed page for each subject. To discuss a Massachusetts criminal case, call Serpa Law Office at 617.936.0201 or request a free consultation.

The Criminal Process

The pages in this section explain how a case begins, when arraignment creates a CORI entry, how a Superior Court indictment differs from a District Court complaint, and what procedures may end the case before trial.

Article 30 of the Massachusetts Declaration of Rights requires separation among the legislative, executive, and judicial departments. The Massachusetts Legislature defines statutory offenses, establishes authorized penalties and dispositions, and assigns jurisdiction. The district attorney decides which charges the Commonwealth will pursue and exercises prosecutorial discretion, while the judge rules on motions, sets conditions of release, conducts plea proceedings, makes trial rulings, and imposes the sentence. Separate pages listed below explain what the Legislature, a district attorney, and a judge can and cannot decide in a criminal case.

  • Clerk-Magistrate Hearings (G.L. c. 218, § 35A). In an eligible case, a clerk-magistrate may deny a complaint application before any complaint issues, arraignment occurs, or arraignment-based CORI entry arises. The Clerk-Magistrate Hearing FAQ answers common questions, while the firm’s procedural guide explains what happens during the hearing.
  • Massachusetts Bail. The presumption of release on personal recognizance under G.L. c. 276, § 58, the factors an official weighs, bail at the police station, why dangerousness may not raise the amount, and same-day review in the Superior Court.
  • Dangerousness Hearings Under Section 58A. When the Commonwealth may seek detention without bail, the qualifying offenses, what it must prove, and how the defense answers it.
  • Boston Municipal Court Case Stages. What happens at each stage of a criminal case in the eight divisions of the Boston Municipal Court.
  • Arraignment in Massachusetts. At arraignment, the court records the charge and plea, creates the CORI entry, and addresses bail, dangerousness, and conditions of release. The page also explains how an eligible clerk-magistrate hearing can prevent arraignment.
  • Arrests and Arrest Warrants in Massachusetts. How warrantless arrests differ from a summons, when a warrant is required, and what to do in the first hours after arrest. See What to Do in the First 24 Hours After a Massachusetts Arrest.
  • Massachusetts Grand Jury Indictments. How Superior Court felony cases begin, when an indictment is required, and what the defense can do before and after the grand jury votes.
  • Massachusetts Courts, State Prison, and House of Correction. The difference between a house of correction and a state prison sentence, which court hears which cases, and how sentencing authority shapes defense strategy.
  • How Criminal Cases Begin in Massachusetts Courts. The three ways a case begins in the Massachusetts criminal system, through arrest, summons, and clerk’s hearing.
  • How Criminal Cases Get Dismissed in Massachusetts. Who controls a dismissal and on what grounds: the district attorney’s authority before arraignment, the narrow grounds for judicial dismissal, motions to dismiss for lack of probable cause, and what a dismissal means for a record.
  • Violating a Continuance Without a Finding in Massachusetts. A CWOF is not a guilty conviction under ordinary Massachusetts criminal law, although a statute or rule may treat it as a conviction for a specified purpose. A new offense or another violation can lead to a surrender hearing and entry of a guilty finding.
  • Massachusetts Probation Violation Defense Lawyer. What a notice of surrender starts, the preliminary and final hearings, detention between them, and what a finding of violation permits the judge to do.
  • Defenses to a Massachusetts Probation Violation. The grounds on which a revocation is contested, including the reliability of hearsay at the hearing, the ability to pay, and the conditions the order never imposed.
  • Transferring Massachusetts Probation to Another State. Moving supervision under the Interstate Compact for Adult Offender Supervision, and the conditions a transfer requires.
  • Massachusetts Warrant Removal and Out-of-State License Holds. Clearing a default or arrest warrant, and the out-of-state license holds a Massachusetts warrant can trigger.
  • Interstate Driver’s License Consequences. How a Massachusetts case can affect a license in another state and how an out-of-state suspension can affect a Massachusetts license, under G.L. c. 90, §§ 22(c) and 22(h), the Driver License Compact at § 30B, and the National Driver Register. Covers clearing the warrant and then applying to the Registry of Motor Vehicles for reinstatement.
  • What a Massachusetts District Attorney Can and Cannot Decide. The district attorney, elected under G.L. c. 12, § 12, decides whether the Commonwealth proceeds on a charge, seeks an indictment, enters a nolle prosequi under Mass. R. Crim. P. 16, moves for pretrial detention under G.L. c. 276, § 58A, makes the plea offer, and makes the sentencing recommendation. A clerk-magistrate or a judge issues the complaint on probable cause. A judge, a clerk, or a bail commissioner sets bail under G.L. c. 276, § 58. A jury decides guilt or innocence and issues a verdict at trial. A judge imposes the sentence. Article 30 of the Declaration of Rights separates the executive decisions from the judicial ones. The page names the judge, clerk-magistrate, grand jury, jury, or prosecutor who makes each one.
  • What a Massachusetts Judge Can and Cannot Decide in a Criminal Case. A judge rules on every motion, sets the conditions of release under G.L. c. 276, § 58, decides whether to accept a plea under Mass. R. Crim. P. 12, and imposes the sentence within the range the statute provides. Article 30 of the Declaration of Rights also marks the limits. A judge cannot dismiss a legally adequate charge over the Commonwealth’s objection, cannot enter a nolle prosequi, and cannot reduce a charge on a plea without the prosecutor’s agreement. The page states each decision in turn, separates District Court and Boston Municipal Court practice from Superior Court practice, and names the judge, clerk-magistrate, jury, or prosecutor who decides.
  • What the Massachusetts Legislature Decides in a Criminal Case. Before a case reaches court, criminal law legislation has already fixed the elements of the offense the Commonwealth must prove and whether the offense is a felony or a misdemeanor under G.L. c. 274, § 1. The same legislation decides which court department hears the case under G.L. c. 212, § 6 and c. 218, § 26, and the maximum sentence and any mandatory minimum. The same statutes create the continuance without a finding, pretrial probation, and diversion, write the bail factors and the § 58A offense list, create the clerk-magistrate hearing, and set the sealing periods in G.L. c. 276, § 100A. The page takes each of those decisions in turn and states what a new act does, and does not do, to a case already pending.

Criminal Court Practice: Trial, Evidence, and Sentencing

The pages in this section cover the courtroom itself, from the motions filed on the eve of trial through the sentence and the motions available after it.

  • Massachusetts Criminal Court Practice. The overview of the trial stages, the evidence rules that govern them, and how a record is preserved for appeal.
  • Trial Motion Practice. Motions in limine, required findings, mistrial, severance, and the preservation rules that decide what an appellate court will consider.
  • Rule 25 and the Required Finding of Not Guilty. The motion that ends a case on legally insufficient evidence: the Latimore standard, timing and renewal when the Commonwealth rests, and the judge’s power after the verdict to acquit or reduce the charge under Rule 25(b)(2).
  • Mistrials, Double Jeopardy, and Retrial. When a trial may end without a verdict, how consent and objections affect retrial, what manifest necessity requires, and how partial verdicts and double jeopardy challenges work.
  • Jury Selection. The juror questionnaire, attorney-conducted voir dire under G.L. c. 234A, challenges for cause, and the limits on peremptory challenges.
  • Opening Statements and Closing Arguments. What each argument may contain, the limits a prosecutor may not cross, and how an objection to an improper argument is preserved.
  • Sentencing in the District Court and Boston Municipal Court. The available dispositions, probation and revocation exposure, credit, restitution, and assessments.
  • Correcting a Criminal Sentence. Revision and revocation under Mass. R. Crim. P. 29, relief from an unlawful sentence under Rule 30(a), and the finality rules that limit both.

Constitutional Rights in Massachusetts Criminal Cases

The pages in this section explain how federal and Massachusetts constitutional protections affect police stops, searches, questioning, compelled testimony, evidence, and trial.

Criminal Records and Case Outcomes

The stage and disposition determine whether a case creates a CORI entry and how later sealing rules apply.

If a clerk-magistrate denies an application before a complaint issues, that application creates no arraignment-based CORI entry. A CWOF requires an admission to sufficient facts and remains in the court record after dismissal unless it is sealed. Federal immigration law and professional regulators may apply their own rules to that disposition. The pages in this section explain CORI access, dismissals, CWOFs, pretrial probation, diversion, sealing, expungement, and profession-specific reporting duties.

Domestic Violence and Restraining Orders

Massachusetts domestic violence allegations can produce several proceedings within a short period. Police may make an arrest, the court may impose criminal release conditions, and a separate 209A case may require the defendant to leave a home or surrender firearms. District Attorney’s Offices commonly continue a prosecution even when the complaining witness later asks that it end. The pages below address the criminal charges, civil orders, evidence, and collateral consequences separately.
