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.

• 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.

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.

• The Right to Remain Silent in Massachusetts. The Fifth Amendment and Article 12, Miranda rights, the Nickerson prearrest-silence standard, the phone-passcode question, and the right not to testify at trial. See the Fifth Amendment right to refuse a passcode.

• The Massachusetts Wiretap Statute and Secret Recordings (G.L. c. 272, § 99). Massachusetts generally prohibits secretly recording the audio of a conversation without all parties’ consent. The statute separately prohibits knowing use or disclosure of a communication intercepted in violation of the statute, subject to statutory and constitutional limits. Short answers are in the wiretap and secret recording FAQs.
• Phone, Computer, and Digital Searches in Massachusetts. When police may seize and search a phone or computer, the warrant and nexus requirements, the scope of a digital warrant, passcodes and the Fifth Amendment, and location data.
• Traffic Stops, Exit Orders, and Pretext Searches. When police may stop a vehicle, how long the stop may last, exit orders under Article 14, patfrisks, searches of bags and belongings, the marijuana odor cases, and racially motivated stops.
• The Fifth Amendment in Civil Cases. Invoking the Fifth in a 209A session, a deposition, or another civil proceeding while criminal exposure is open.
• Cross-Examination in Massachusetts Criminal Trials. The confrontation right in practice: how a witness is impeached by bias, prior inconsistent statements, and omissions, what the rules of evidence permit for each kind of witness, and how the same discipline carries into a 209A or 258E hearing.
• Self-Defense in Massachusetts. Reasonable force, the duty to retreat, defense of another, and the Adjutant evidence a jury may hear about who started the fight.
• Double Jeopardy in Massachusetts. The same-offense test, when jeopardy attaches, retrial after a mistrial or appeal, and how a double jeopardy claim is raised before a second trial.
• Excited Utterances and Spontaneous Utterances When an Accuser Recants. The hearsay exception and the confrontation rules that decide whether a 911 call or an officer’s account comes before the jury when an accuser recants or refuses to testify, and the impeachment of the absent declarant that Section 806 then allows. Common questions are in the excited utterance and recanting accuser FAQs.

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.

• Massachusetts Criminal Records (CORI). What a CORI is, when it is created, who can see it at each level of access, and how it affects employment, housing, licensing, and immigration.
• CWOF, Pretrial Probation, and Diversion in Massachusetts. How a continuance without a finding differs from pretrial probation and diversion, and how each disposition may affect professionals, commercial drivers, and noncitizens. See the CWOF, Pretrial Probation, and Diversion FAQs.
• Case Dismissals in Massachusetts. How a clerk-magistrate may deny a complaint application before a case begins, how courts address motions to suppress and motions to dismiss after a complaint issues, how diversion can end a prosecution, and why the procedural stage matters for CORI.
• Sealing and Expunging a Massachusetts Criminal Record. Waiting periods, administrative sealing compared with judicial sealing, expungement eligibility, and what sealing does and does not do. See the CORI Sealing and Expungement FAQ and the Massachusetts sealing and expungement standards page.
• Expunging or Sealing a Federal Criminal Record. Whether a Massachusetts sealing or expungement order applies to the corresponding FBI entry. G.L. c. 276, § 100T requires Massachusetts to transmit the order and request corresponding federal action, while 28 C.F.R. § 16.34 provides the procedure for challenging an inaccurate or incomplete FBI record. The page also addresses actual federal records, the First Circuit’s decision in United States v. Coloian, the narrow § 3607 procedure, and pardons.
• Criminal Defense for Licensed Professionals in Massachusetts. Licensing board reporting obligations, the consequences of a continuance without a finding for physicians, attorneys, nurses, and FINRA registrants, and the four-step defense sequence.

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.
