Massachusetts service under Mass. R. Civ. P. 4 via constables and deputy sheriffs. Out-of-state subpoenas via commission under G.L. c. 233 §§ 46–47.
Massachusetts service of process is governed by the Massachusetts Rules of Civil Procedure, particularly Rule 4, and is distinctive in two important respects. First, Massachusetts retains an active constable system alongside deputy sheriffs for civil process — private process servers have a limited role and must typically work through these officers. Second, as of April 2026 Massachusetts has NOT adopted the Uniform Interstate Depositions and Discovery Act — House Bill H.5056 and its companions are pending in the General Court. Out-of-state counsel seeking discovery in Massachusetts must therefore use the commission-based procedure under G.L. c. 233 §§ 46–47, which predates the UIDDA and requires a Massachusetts court to issue a subpoena on the basis of a commission from the out-of-state court.
This is practical guidance, not legal advice. Massachusetts service of process rules are found in Mass. R. Civ. P. 4. For service of process nationwide, Served 123 LLC handles Massachusetts and all 49 other states with qualified servers.
Under Mass. R. Civ. P. 4(c), service is made by a sheriff, deputy sheriff, constable, or by any other person who is not a party, is at least 18 years old, and is specially appointed by the court for that purpose. In practice, the bulk of Massachusetts civil service is performed by constables (appointed by the local municipality) and deputy sheriffs (appointed by the county sheriff). Each carries authority in defined geographic areas. Private process servers in Massachusetts must therefore coordinate with one of these officers or seek court appointment for specific cases.
Personal service under Mass. R. Civ. P. 4(d)(1) is accomplished by delivering a copy of the summons and complaint to the individual personally. The constable or deputy sheriff files a return of service identifying the date, time, and location. Massachusetts practitioners typically include hand-delivery as the default method when the defendant's address is verified and the defendant is expected to be present.
Mass. R. Civ. P. 4(d)(1) authorizes substituted service by leaving copies at the defendant's "last and usual place of abode" with a person of suitable age and discretion then residing there. Massachusetts uses "last and usual place of abode" — a classic common-law formulation — rather than "dwelling house or usual place of abode." The co-resident recipient should be at least 14 years old and capable of understanding that the papers are important. Abode service at an address where the defendant no longer lives is invalid, even if the defendant receives mail there.
Massachusetts does not authorize service of an initial summons and complaint by ordinary mail. G.L. c. 223, § 37 and Mass. R. Civ. P. 4(e) permit service outside the Commonwealth by certified mail, return receipt requested, when the Massachusetts court has personal jurisdiction over the out-of-state defendant. First-class mail is never valid for initial process on Massachusetts residents.
Service on Massachusetts corporations, LLCs, and partnerships is made under Mass. R. Civ. P. 4(d)(2) on an officer, a managing or general agent, or the person in charge of the principal office in Massachusetts. The Massachusetts Secretary of the Commonwealth's Corporations Division online database (corp.sec.state.ma.us) identifies the registered agent and address. If the registered agent cannot be served after reasonable diligence, G.L. c. 156D, § 5.04 (for corporations) and c. 156C, § 5(b) (for LLCs) authorize service on the Secretary of the Commonwealth as substitute agent.
Massachusetts's long-arm statute at G.L. c. 223A, § 3 extends jurisdiction to defendants with specified contacts with the Commonwealth. Service on out-of-state defendants is authorized under Mass. R. Civ. P. 4(e) by personal delivery in the destination state, by certified mail return receipt requested, or in accordance with the law of the destination state. G.L. c. 223, § 37 also permits service on the Secretary of the Commonwealth as substitute agent for nonresidents engaged in business in Massachusetts.
Mass. R. Civ. P. 4(d)(1) and G.L. c. 223, § 34 permit service by publication when the defendant is absent or cannot be found after diligent search. The plaintiff must file an affidavit and secure a court order directing the method of notice. Publication typically runs once a week for three successive weeks in a newspaper of general circulation, with a copy mailed to the defendant's last known address if known. Massachusetts courts are cautious about publication service and regularly require additional diligence.
Massachusetts has NOT adopted the Uniform Interstate Depositions and Discovery Act as of April 2026. Several bills remain pending in the General Court, including H.5056 and companion bills in both chambers. Out-of-state counsel seeking discovery in Massachusetts therefore rely on the commission procedure under G.L. c. 233, §§ 46–47: the foreign court issues a commission directed to a Massachusetts court or officer, who then issues a Massachusetts subpoena to compel the testimony or records. This is substantially more cumbersome than the clerk-issued UIDDA process used in neighboring states and is the single most important practical issue for out-of-state practitioners working in Massachusetts.
Mass. R. Civ. P. 4(j) requires service within 90 days of filing the complaint. If service is not completed within that window, the action may be dismissed without prejudice unless the plaintiff shows good cause for an extension. This 90-day rule (amended from an earlier 90-day version in the 2017 revisions) is enforced by case-management orders in the Superior Court and BMC/District Court departments.
The return of service — typically filed by the constable or deputy sheriff on the reverse of the summons — identifies the date, time, place, manner of service, and person served (with the relationship noted for abode service). Under G.L. c. 235, § 31 the return is prima facie evidence of the facts stated. Amendment of a defective return under Mass. R. Civ. P. 4(h) is permitted, but the underlying service must have been valid.
Practitioners routinely handle Massachusetts service by coordinating with constables and deputy sheriffs across the seven Trial Court departments, processing commission-based foreign subpoenas under G.L. c. 233 §§ 46–47, registered-agent service on Massachusetts corporations and LLCs through the Secretary of the Commonwealth's Corporations Division, and substitute service on the Secretary when registered agents cannot be reached.

No. Massachusetts, like every other state, prohibits parties from serving their own process. The server must be an adult non-party or an authorized officer/licensed server per Massachusetts rules.
Massachusetts Rule 4(j) requires service within 90 days of the filing of the complaint. If service is not completed within that window, the action is subject to dismissal without prejudice unless the plaintiff shows good cause for an extension. Case-management orders in the Superior Court and BMC/District Court departments enforce the deadline.
Ordinary mail is not a valid method for serving an initial summons and complaint in Massachusetts. Mass. R. Civ. P. 4(e) and G.L. c. 223, § 37 permit certified mail, return receipt requested, only for service outside Massachusetts when the court has long-arm jurisdiction. Initial service on Massachusetts residents must go through a constable, deputy sheriff, or court-appointed server.
Mass. R. Civ. P. 4(d)(2) authorizes service on a corporation's officer, managing or general agent, or the person in charge of the principal office in Massachusetts. The Secretary of the Commonwealth's Corporations Division database identifies the registered agent. If the agent cannot be found after reasonable diligence, G.L. c. 156D, § 5.04 permits service on the Secretary of the Commonwealth as substitute agent.
Massachusetts follows the majority refused-acceptance rule. The server may place the papers in the defendant's immediate presence after identifying the nature of the documents. Service is valid despite refusal.
Massachusetts's long-arm statute at G.L. c. 223A, § 3 extends jurisdiction to out-of-state defendants with specified contacts. Service is authorized under Mass. R. Civ. P. 4(e) by personal delivery in the destination state, by certified mail return receipt requested, or in accordance with the law of the destination state. Separately, G.L. c. 223, § 37 permits substituted service on the Secretary of the Commonwealth for certain nonresidents.
Start with a skip trace, then move for service by publication on a court order supported by an affidavit documenting diligent inquiry. three successive weeks in a newspaper of general circulation in the county where the action is pending.
