How to File a Lawsuit in Massachusetts: Steps, Courts, and Requirements

Filing a lawsuit in Massachusetts involves navigating a structured court system governed by the Massachusetts General Laws (M.G.L.), the Massachusetts Rules of Civil Procedure, and the administrative rules of each individual trial court department. The process differs substantially depending on the dollar amount at stake, the subject matter of the dispute, and the court division with proper jurisdiction. This page describes the procedural framework, court selection criteria, filing requirements, and the key decision points that determine how a civil action proceeds from initiation to resolution. The broader regulatory structure governing Massachusetts courts is documented at /regulatory-context-for-massachusetts-us-legal-system.

Definition and scope

A civil lawsuit in Massachusetts is a formal legal proceeding initiated by a plaintiff against one or more defendants to obtain a judicial remedy — typically monetary damages, injunctive relief, or declaratory judgment. The proceeding is governed by M.G.L. Chapter 223 (commencement of actions), Chapter 231 (pleadings and civil procedure), and the Massachusetts Rules of Civil Procedure, which are promulgated by the Supreme Judicial Court (M.G.L. c. 211B).

Scope of this page: This reference covers civil litigation initiated in Massachusetts state courts under Massachusetts law. It does not address criminal prosecution procedures (see Massachusetts Criminal Procedure Overview), family law petitions filed in the Probate and Family Court (see Massachusetts Probate and Family Court), or actions filed in the United States District Court for the District of Massachusetts under federal jurisdiction (see Federal Courts in Massachusetts). Administrative agency proceedings governed by M.G.L. Chapter 30A fall under Massachusetts Administrative Law and are also outside this page's coverage.

The Massachusetts court system is divided into the Trial Court, which includes 7 distinct departments, and the appellate tier comprising the Appeals Court and the Supreme Judicial Court. Proper court selection — a threshold determination before any complaint is drafted — depends on jurisdictional statutes, not plaintiff preference.

How it works

The civil litigation process in Massachusetts follows a defined procedural sequence. Each phase has mandatory requirements established by statute or court rule.

1. Determine the proper court

Selecting the correct trial court department is the foundational step. The Massachusetts Court System Structure establishes five primary civil trial court departments:

• Superior Court (M.G.L. c. 212): Unlimited civil jurisdiction; mandatory for claims exceeding $50,000 and for jury trials on claims of that magnitude. See Massachusetts Superior Court Jurisdiction.
• District Court (M.G.L. c. 218): Civil jurisdiction up to $50,000. See Massachusetts District Court Jurisdiction.
• Housing Court (M.G.L. c. 185C): Specialized jurisdiction over residential and commercial landlord-tenant disputes, housing code enforcement, and related matters. See Massachusetts Housing Court.
• Land Court (M.G.L. c. 185): Exclusive jurisdiction over title disputes, registered land, zoning appeals, and foreclosure-related actions. See Massachusetts Land Court.
• Small Claims Session: Streamlined process for claims up to $7,000 (or $10,000 for property damage from a motor vehicle accident), administered within the District Court and Boston Municipal Court under M.G.L. c. 218, §§ 21–25. See Massachusetts Small Claims Court.

2. Verify the statute of limitations

The complaint must be filed within the period prescribed by M.G.L. Chapter 260. The standard limitations periods include:

• Contract claims: 6 years (M.G.L. c. 260, § 2)
• Tort claims (personal injury, property damage): 3 years (M.G.L. c. 260, § 2A)
• Medical malpractice: 3 years from discovery, subject to a 7-year repose period (M.G.L. c. 260, § 4)

See Massachusetts Statute of Limitations for a full breakdown by claim type.

3. Draft and file the complaint

The complaint must conform to Mass. R. Civ. P. Rule 8, which requires a short and plain statement of the claim, a statement of jurisdiction, and a demand for relief. In Superior Court, the complaint must be filed with the clerk of the appropriate county division along with a civil action cover sheet (Uniform Superior Court Rule 29).

Filing fees vary by court and claim amount. Fee waiver (indigency affidavit) procedures are available under M.G.L. c. 261, §§ 27A–27G. See Massachusetts Court Fees and Waivers.

4. Serve the defendant

Service of process is governed by Mass. R. Civ. P. Rule 4. For individual defendants, service is typically accomplished by a sheriff, constable, or disinterested adult delivering the summons and complaint in hand or at the defendant's last and usual place of abode. Service on corporations follows M.G.L. c. 223, § 37, which permits service on the registered agent or principal officer.

5. Defendant's response and discovery

The defendant has 20 days after service to file an answer or responsive motion under Mass. R. Civ. P. Rule 12. Discovery — including interrogatories (Rule 33), depositions (Rule 30), and document requests (Rule 34) — proceeds under the Massachusetts Rules of Civil Procedure following the close of pleadings. See Massachusetts Civil Procedure Overview for the complete discovery framework.

6. Pre-trial and trial

Cases not resolved through Massachusetts Alternative Dispute Resolution or dispositive motions proceed to trial. Jury trials in Superior Court are governed by Article XII of the Massachusetts Declaration of Rights and M.G.L. Chapter 234. Evidence rules are set by the Massachusetts Guide to Evidence, published by the Supreme Judicial Court. See Massachusetts Evidence Rules and Massachusetts Jury System.

Common scenarios

Civil lawsuits in Massachusetts arise across a defined set of substantive legal categories. The applicable law and preferred court differ by scenario:

Contract disputes — Claims for breach of a written or oral agreement are among the most frequently filed civil actions. Superior Court handles high-value commercial contract disputes; District Court handles claims under $50,000. See Massachusetts Contract Law.

Tort claims — Personal injury, negligence, and intentional tort actions are governed by common law and M.G.L. Chapter 231. Motor vehicle tort claims under the no-fault threshold system (M.G.L. c. 231, § 6D) require satisfying a $2,000 medical expense threshold before a pain-and-suffering claim is cognizable in court. See Massachusetts Tort Law.

Consumer protection claims — Actions under M.G.L. c. 93A (the Massachusetts Consumer Protection Act) allow for double or treble damages and attorney's fees in cases of unfair or deceptive trade practices. A demand letter must be sent at least 30 days before filing. See Massachusetts Chapter 93A Consumer Protection.

Landlord-tenant disputes — Summary process (eviction) and claims for return of security deposits are filed in Housing Court or District Court under M.G.L. Chapter 239. See Massachusetts Landlord-Tenant Law and Massachusetts Housing Court.

Employment claims — Wage theft, discrimination, and retaliation claims may be filed in Superior Court or, in discrimination cases, pursued first through the Massachusetts Commission Against Discrimination (MCAD) under [M.G.L. c. 151B](https://malegislature.gov/Laws/GeneralLaws/PartI/T
