Was I served correctly in New Hampshire?

New Hampshire service of process is anchored in N.H. Super. Ct. R. 4. Personal service is the safest path, and substituted service is available only when the rule's conditions are met. New Hampshire generally does not treat ordinary mail as enough for initial service of a lawsuit. Service by publication is a last-resort method for defendants who cannot be located after diligent effort.

The practical stakes are deadline and proof. Defendants usually have 30 days to respond after service. The server is typically a sheriff, marshal, or other officer authorized by the court, and a proof or affidavit of service should be filed so the court record shows exactly how service happened. Email, text, or social-media service should not be assumed valid unless a judge specifically authorizes an alternative method.

Important: Treat this as the statewide civil-case baseline for New Hampshire. Evictions, family cases, service on corporations, service on government agencies, and local court rules can add extra steps. If you want to challenge service, preserve that objection before arguing the merits of the case.

Service methods

Personal service

Allowed

Personal delivery is the cleanest way to serve a summons and complaint in New Hampshire.

Substituted service

Allowed

Substituted service may be used when the rule permits delivery to another responsible person or location after the required effort at personal service.

Service by mail

Not allowed

Ordinary mail alone is not a safe method for initial service in New Hampshire; use personal service or another method authorized by the rule or court order.

Service by publication

Allowed

Publication is typically reserved for cases where the defendant cannot be found and the court allows notice by publication.

Electronic service (email/text)

Not allowed

Electronic service is not the default for initial process; get a court order before relying on email, text, or social-media notice.

Who can serve?

Sheriff or marshal only

Use a sheriff, marshal, or other officer authorized by the court. If there is any doubt, confirm with the clerk or hire a professional process server.

Other states

Not legal advice. Service-of-process rules carry many exceptions for specific case types (eviction, divorce, suit against a corporation, suit against a state agency). If you've been served and think the service was defective, talk to a lawyer about a motion to quash before answering on the merits.
