LLC Registered-Agent and Registered-Office Requirements in New Hampshire

At a glance

Requirements one by one

Governing law and terminology

RSA chapter 304-C is the New Hampshire Revised Limited Liability Company Act. It uses the paired terms registered office and registered agent. The agent receives service of process, notices, and demands for the LLC.

Continuous designation duty

RSA 304-C:36(I) requires every domestic LLC to have and maintain both a New Hampshire registered office and a registered agent. The certificate of formation must state the office address and the agent's name and address under RSA 304-C:31(II)(b).

The office and agent are linked rather than independent: the qualifying individual's residential or business office, or the qualifying entity's business office, must be identical with the registered office.

Eligible individual

An individual agent must reside in New Hampshire. The person's residential or business office must be the registered office. The Act states no separate age, citizenship, professional-license, or quantified availability condition.

The Secretary of State expressly says an owner, manager, or employee may be listed when the person can be located at the New Hampshire agent address.

Eligible entity and self-service

The entity-agent classes are a corporation organized or authorized under RSA 292, 293-A, or 294-A; an LLC formed or authorized under chapter 304-C; a professional LLC formed or authorized under chapter 304-D; or an LLP formed or authorized under RSA 304-A:44. Each entity's business office must be identical with the registered office.

The LLC-agent category does not say “another” LLC and contains no express self-agent exclusion. The Secretary's clearest self-service guidance addresses individual owners, managers, and employees; those people qualify when they meet the individual residency and location rules.

Registered office, address, and hours

The registered office may be the same as any LLC place of business. Change filings must state its street address, and after a change the registered- office street address and the agent's business-office street address must be identical.

Current LLC-1 instructions call for a New Hampshire street or physical address where the agent can be found for in-hand service and reject a P.O. box. The Secretary's guidance says the agent generally should be available there during regular business hours. That is useful filing guidance, but RSA 304-C:36 states no exact daily hours or enacted schedule.

Consent and initial filing

The certificate names the agent and supplies the registered-office address. RSA 304-C:28 ordinarily requires the filing signature of a manager, or a member if there is no manager, while also recognizing the specified fiduciary and authorized-person alternatives.

Neither RSA 304-C:31 or :36 nor current Form LLC-1 requires a separate agent consent, acceptance statement, acknowledgment, or agent signature. LLC-1 uses the manager/member filing-signature block.

Change, resignation, and replacement

The LLC changes its office, agent, or both by filing the current information, the successor information, and an affirmation that the office and agent's business-office street addresses will remain identical. Subject to a permitted effective time, an accepted filing is effective on filing under RSA 304-C:29.

An agent moving elsewhere in New Hampshire may file the office-address change itself; the statement is signed only by the agent and must recite that a copy was mailed to the LLC.

To resign, the agent signs and files a written notice. The Secretary of State mails a copy to the LLC's principal office. The appointment ends on the earlier of a successor's appointment or 31 days after filing. The resignation may also discontinue the registered office.

Agent duties and service

RSA 304-C:37(I) makes the registered agent the LLC's agent for any process, notice, or demand required or permitted to be served on the company. The cited Act sections state no separate private-agent forwarding deadline or damages rule.

The Secretary describes the practical role as receiving official documents, legal process, and court notices. That guidance does not create an additional statutory forwarding timetable.

Lapse consequences and fallback service

If the LLC has no agent or reasonable diligence cannot serve the agent, RSA 304-C:37 permits registered or certified mail, return receipt requested, to the principal office. Service is perfected at the earliest of company receipt, the date on a return receipt signed for the company, or five days after correctly addressed, postage-paid mailing. Other lawful service methods remain possible.

Being without the registered agent or registered office for at least 60 days is an administrative-dissolution ground. So is failing for 60 days to notify the Secretary of an agent or office change, agent resignation, or office discontinuance. Once the Secretary determines a ground exists, RSA 304-C:137 directs administrative dissolution by a mailed notice that states the ground and effective date and encloses a reinstatement application. The Act does not add a second pre-dissolution cure period after the 60-day threshold. The LLC may seek reinstatement within three years after dissolution.

What trips people up

The office must be the agent's own office. New Hampshire does not merely ask for any in-state company address. The agent's residential or business office must be identical with the registered office.

The form's resident wording is individual-focused. LLC-1 says the agent must reside in New Hampshire, but RSA 304-C:36 separately and expressly permits the listed corporation, LLC/PLLC, and LLP entity agents with New Hampshire business offices.

“Regular business hours” is guidance, not a numbered statute. The Secretary says the agent generally should be available then, but chapter 304-C does not state exact hours.

The 60 days come before dissolution, not after notice. The agent/office lapse or reporting failure must persist for 60 days. Section 304-C:137 then directs a notice of dissolution; it does not supply another 60-day cure window.

Common questions

Can an owner serve? Yes. The Secretary expressly permits an owner, manager, or employee to be listed when the individual can be located at the qualifying New Hampshire address.

Can the registered office be a P.O. box? No. Current Secretary guidance and LLC-1 instructions require the physical street address where the agent can be found.

Does losing the agent prevent service? No. Registered or certified mail to the principal office is available when the agent is absent or cannot with reasonable diligence be served, and other lawful methods remain available.
