Maine Service of Process Rules for Civil Lawsuits

Service of process is the mechanism by which a defendant receives notice of a lawsuit. Maine's service rules are codified primarily in the Maine Rules of Civil Procedure (M.R. Civ. P.) and the Maine Revised Statutes (Me. Rev. Stat.). Proper service is essential—defective service can result in a court lacking personal jurisdiction over the defendant, leading to dismissal of your case.

Personal Service (Hand Delivery)

Personal service is the most straightforward and preferred method of service. It involves physically handing a copy of the summons and complaint to the defendant in person.

Under M.R. Civ. P. 4(c)(1), personal service is effected by:

Delivering a copy of the summons and complaint to the individual defendant personally

Delivering the documents to an agent authorized to receive service on behalf of the defendant

Delivering the documents to an officer of a corporation or limited liability company

Personal service can occur anywhere—at the defendant's home, workplace, on the street, or anywhere else the defendant is found within the State of Maine or within the territorial jurisdiction of the court. There is no time restriction on when personal service can be attempted during normal business hours or otherwise.

Key advantage: Personal service is the most reliable form of service and is least likely to be challenged on jurisdictional grounds.

Substituted Service at Residence or Workplace

When personal service cannot be readily obtained, substituted service may be used under M.R. Civ. P. 4(c)(2).

Substituted service at the defendant's residence requires:

Leaving the summons and complaint with a person of suitable age and discretion residing in the household (not just any person present—courts interpret this to mean someone mature enough to understand the importance of the documents)

Service must be made at the defendant's usual place of abode or dwelling

The defendant must be informed of the contents of the documents

Service is effective only after five days have passed following the delivery to the household member

Substituted service at the defendant's place of business or employment requires:

Leaving documents with the person in charge or a competent adult employee

Service at the defendant's usual place of business

Same five-day waiting period applies

Critical Maine requirement: The five-day waiting period is mandatory under M.R. Civ. P. 4(c)(2). The summons and complaint must remain in the recipient's possession for at least five days before the defendant is deemed served. This distinguishes Maine from some other jurisdictions that do not impose this waiting period.

Common pitfall: Leaving documents with a delivery service or in a mailbox does not constitute valid substituted service. The person receiving the documents must be physically present and capable of understanding their significance.

Service by Mail

Maine permits service by mail in limited circumstances, primarily through an opt-in mechanism:

Under M.R. Civ. P. 4(c)(4), service by mail is allowed:

By certified mail, return receipt requested to the defendant's last known address

Service is complete upon receipt (when the return receipt is signed)

This method requires the defendant to actually receive and sign for the mail

Regular mail (non-certified) is NOT a permitted method of service under Maine Rules, except in special circumstances where the court specifically orders it or where a defendant has agreed to accept service by regular mail in writing.

Practical note: Certified mail with return receipt is useful for out-of-state defendants, but you must obtain the signed return receipt to prove service was actually received.

Service by Publication

When a defendant cannot be located or personal service cannot be achieved despite diligent efforts, service by publication may be available under M.R. Civ. P. 4(c)(5).

Requirements for service by publication:

The plaintiff must demonstrate to the court that diligent efforts have been made to locate the defendant and effect personal service

The plaintiff must file an affidavit or declaration detailing the efforts made

The court must issue an order authorizing service by publication

Publication must occur in a newspaper of general circulation in the county or district where the defendant is likely to receive notice

Specifics on publication:

Number of publications: The order typically requires publication at least three times in a newspaper of general circulation

Timing: Publications must be spaced at least three days apart (or as the court orders)

Duration: The defendant is given at least 30 days from the first publication to appear

A copy of the published notice must also be served by certified mail to the defendant's last known address, if known

When authorized: Service by publication is typically authorized only in cases involving property within the state (to establish in rem or quasi in rem jurisdiction) or when the court finds that other methods of service cannot be accomplished with due diligence.

Service on Corporations and Limited Liability Companies

Corporations and LLCs are treated as "persons" under Maine law and must be served according to M.R. Civ. P. 4(c)(3).

Proper service on a corporation or LLC includes:

Service on the registered agent for service of process (the entity's designated representative)

Service on any officer, director, or managing member of the corporation or LLC

Service on any employee in charge of the principal office or place of business

Finding the registered agent:

The registered agent information is maintained by the Maine Secretary of State, Division of Corporations

You can search the corporate database online at maine.gov to find the registered agent's name and address

The registered agent is the entity's official point of contact for legal proceedings

Service on out-of-state corporations:

If an out-of-state corporation or LLC is doing business in Maine, service can be made on the Secretary of State under Me. Rev. Stat. tit. 13, § 222 (formerly the "long-arm" statute provision for nonresident corporations)

Service on the Secretary of State must be followed by certified mail service to the corporation's principal office

Service on Government Entities

Government entities—state, county, and municipal—have special service requirements under Me. Rev. Stat. tit. 13, § 222-A and M.R. Civ. P. 4(c)(6).

Service on the State of Maine:

Service must be made on the Attorney General (or their designated representative)

The Attorney General's office is located in Augusta

Additionally, a copy must be served on any specific state agency that is a party to the lawsuit

Service on a County:

Service must be made on the county attorney or a deputy county attorney

A copy must also be served on the county commissioners or chairperson

Service on a Municipality (City or Town):

Service must be made on the town or city manager or mayor

Or service can be made on the town clerk or city clerk

A copy should be served on the town or city solicitor if one is employed

Special consideration: When suing a government entity, you may also need to comply with notice and filing requirements before commencing the lawsuit. Check the relevant statutes for any pre-suit notice requirements specific to your claim.

Maine Long-Arm Statute and Out-of-State Defendants

Maine's long-arm statute is codified at Me. Rev. Stat. tit. 13, § 222, which allows Maine courts to exercise jurisdiction over out-of-state defendants who:

Transact business in Maine (including online sales or services directed to Maine consumers)

Commit a tort causing injury in Maine

Own, use, or possess property within Maine

Contract to insure any property, person, or risk located in Maine

Are engaged in other activities that constitute minimum contacts with Maine such that jurisdiction does not violate due process

Practical application: If the defendant is outside Maine, you can serve them:

By certified mail (return receipt required)

By any other method permitted under M.R. Civ. P. 4(c) if the defendant is temporarily in Maine

By serving the Maine Secretary of State if the defendant is a nonresident corporation doing business in Maine (followed by certified mail to the out-of-state office)

Important: Establishing personal jurisdiction under the long-arm statute requires showing that the defendant has sufficient "minimum contacts" with Maine. Mere service of process is not enough; the court must have valid jurisdiction.

Who Can Serve Process in Maine

Under M.R. Civ. P. 4(d)(1), process must be served by:

A sheriff of the county where service is to be made

A deputy sheriff

Any person who is not a party to the action and not an attorney for a party, as long as that person is:

- At least 18 years old
- A resident of the State of Maine (or, practically, available to serve documents)

Private process servers are permitted and commonly used. They must be at least 18 years old and cannot have a financial interest in the outcome of the case.

Plaintiff cannot self-serve: The plaintiff or a party to the action cannot serve process themselves—a neutral third party must effect service.

No special certification required: Unlike some states, Maine does not require private process servers to be licensed or certified by the state.

Time Limits for Completing Service

Under M.R. Civ. P. 4(m), service of the summons and complaint must be made:

Within 90 days after the complaint is filed

The court may dismiss the action without prejudice if service is not completed within 90 days, unless the plaintiff shows good cause for the delay

The 90-day period can be extended by the court upon a showing of good cause (diligent efforts but service remains incomplete, for example)

Practical advice: Initiate service promptly after filing. While the 90-day window is relatively generous, delays can result in dismissal. If service cannot be completed within 90 days, file a motion for extension of time before the deadline expires.

Proof of Service and Return of Service

After service is completed, the person who served process must file a return of service (also called a proof of service) with the court.

Return of service requirements under M.R. Civ. P. 4(p):

Must be signed by the person who effected service (sheriff, deputy, or process server)

Must state:

- When service was made (date and time if practical)
- Where service was made (address)
- How service was made (personal service, substituted service, mail, etc.)
- To whom service was made (name and relationship to defendant if substituted service)
- For certified mail: include the signed return receipt
- For substituted service: indicate when the five-day waiting period expires

Affidavit of service: If the process server is unavailable to testify, an affidavit under oath is an acceptable alternative. The affidavit must contain the same information as a return of service and be notarized or signed under penalty of perjury.

Filing requirement: The return of service or affidavit must be filed with the court. It serves as prima facie evidence that service was proper.

Defective Service and Motion to Quash

If service was defective or improper, the defendant may file a motion to quash service under M.R. Civ. P. 12(b)(4) or a motion to dismiss for lack of personal jurisdiction under M.R. Civ. P. 12(b)(2).

Common grounds for quashing service:

Service was not made on a person authorized to receive it

The return of service is incomplete or lacks required information

Service was made outside Maine without proper jurisdiction

Substituted service did not comply with the five-day waiting period

Service by mail was not properly executed (unsigned return receipt)

Waiver of objection: A defendant who responds to the merits of the case or fails to raise the jurisdictional objection in the first responsive pleading may waive the right to challenge service. However, a motion to quash can be raised at any time if the court lacks personal jurisdiction.

Burden of proof: Once service is challenged, the plaintiff bears the burden of proving that service was proper through the return of service, affidavits, or testimony.

Evasion of Service and Alternative Methods

When a defendant actively evades service or cannot be found despite diligent efforts, courts may authorize alternative service methods under M.R. Civ. P. 4(c)(5).

Upon motion by the plaintiff, the court may authorize:

Service by publication (discussed above)

Service by email or electronic means (if the defendant uses email for business or communication)

Service by Facebook or other social media (increasingly recognized by courts when other methods fail)

Service by leaving documents at the residence with instructions for the defendant to appear

Other creative methods reasonably calculated to give the defendant actual notice

Requirement: The plaintiff must demonstrate diligent prior efforts to serve the defendant by standard methods and that those efforts have been unsuccessful.

Example: If a defendant repeatedly refuses to answer the door or has moved without providing a forwarding address, the court might authorize service by certified mail to the last known address and publication in a newspaper.

Service in Special Proceedings

Divorce and Family Law Cases

Service requirements in divorce cases are specified in Me. Rev. Stat. tit. 19, § 652. Service follows the general civil rules, but:

Service must be made personally if possible, or by the authorized alternative methods

If a child is involved, service is critical for custody and support jurisdiction

Service on the opposing party's attorney (if one appears) may be permitted for subsequent motions

Eviction Cases

Eviction (summary dispossession) cases have expedited service requirements under Me. Rev. Stat. tit. 14, § 6002:

Service must be made personally to the defendant/tenant or to an adult at the residence

Service must occur at least 7 days before the hearing (shorter than the civil default timeline)

Service can be made by the plaintiff, a sheriff, or a constable

Posting on the door may be permitted if personal service cannot be achieved

Restraining Orders and Protective Orders

Service on restraining orders (protection from abuse orders) under Me. Rev. Stat. tit. 19, § 4007 requires:

Personal service to the defendant whenever possible

Service by certified mail if personal service cannot be achieved

The defendant must be served before or at the time of the hearing (the order cannot be signed without service or the defendant's presence)

Key Takeaways

Personal service is the gold standard, but Maine permits substituted service (to another household member or workplace employee) with a mandatory five-day waiting period.

Certified mail with return receipt is the primary method for serving out-of-state defendants; regular mail is not permitted.

Service by publication requires a court order and diligent proof of prior unsuccessful service attempts.

Service on corporations or LLCs must be made on the registered agent (found through the Maine Secretary of State database) or an officer/manager.

Government entities require special notice to the Attorney General (state), county attorney (county), or town/city manager (municipality).

Maine's long-arm statute permits jurisdiction over out-of-state defendants with minimum contacts, but service alone does not establish jurisdiction.

Service must be completed within 90 days of filing; any later and you risk dismissal.

The proof of service (return of service or affidavit) must be filed and is prima facie evidence of proper service.

A defendant can challenge service by filing a motion to quash, but waives this objection if they respond on the merits without raising it.

Evasion of service may justify alternative methods, including service by publication or electronic means, upon court order.
