Corporation Registered-Agent Change and Resignation Requirements in Missouri

At a glance

Requirements one by one

Keep both the agent and the matching Missouri office

Mo. Rev. Stat. § 351.370 requires the corporation to continuously maintain a registered office and registered agent in Missouri. The office may be separate from the corporation's own place of business, but it must be the agent's business office.

An individual agent must reside in Missouri. The entity-agent option is a corporation authorized to transact business in Missouri. Current Corp. 59 says the represented corporation may not act as its own agent. The Secretary's FAQ also requires a physical place where process can be served: a P.O. box needs a same-city street address, and a retail mailing store is not accepted.

The board authorizes the corporation's change

The statement under Mo. Rev. Stat. § 351.375 gives the corporation's name, current office and agent, any new office or agent, the successor's written consent, and a declaration that the post-change registered office and agent business office will be identical. It also recites that a duly adopted board resolution authorized the change. The statute states no shareholder-approval step for this filing.

The chair, president, another officer, or a court-appointed fiduciary executes under § 351.046, gives name and capacity, and may use a facsimile, conformed, or electronic signature under Secretary rules. A seal, attestation, acknowledgment, verification, or proof is optional, but filing represents the signer's belief that the statements are true and correct.

The agent has a separate office-move route

When the agent moves its business office, § 351.375.3 permits the agent to move the represented corporation's registered office too. The agent first notifies the corporation in writing, then signs manually or by facsimile and files a statement containing the corporation's current and new office/agent information and reciting that notice was given. The address change takes effect on filing.

Chapter 351 does not create a separate commercial-agent listing or one bulk statement for all represented corporations. It also does not state an agent-initiated name-change route in this section.

Resignation stays pending for 30 days

Under Mo. Rev. Stat. § 351.376, the agent files written notice in duplicate. The Secretary promptly mails the copy to any corporate officer at the officer's last-known address other than the registered office.

Resignation becomes effective when 30 days expire after the Secretary receives the notice. Unlike statutes that accelerate termination on successor appointment, § 351.376 states no earlier-replacement trigger. The corporation therefore should replace the agent promptly without assuming the old appointment ended on filing.

The current fee has a scheduled year-end drop

The corporation's change is effective when the Secretary files it. Current Corp. 59 lists a $10 filing fee. Mo. Rev. Stat. § 351.658 sets a $5 base for an agent/office change and a $5 base for resignation, while § 351.127 authorizes an additional $5 technology fee on chapter 351 charges.

That surcharge expires after December 31, 2026. Unless a later enactment extends it, the statutory charge for these filings falls back to the $5 base on January 1, 2027. Filers should confirm the live form and fee at the time of submission.

The corporate registration report is an alternate change route. Under § 351.120, a successor agent signs written consent that includes the agent's address, and the filing includes written consent stating that a duly adopted board resolution authorized the change. Articles of correction may fix an incorrect statement or defective execution under Mo. Rev. Stat. § 351.049 and generally relate back, subject to protection for a person who relied adversely on the uncorrected filing.

Agent loss preserves service and starts a default clock

Mo. Rev. Stat. § 351.380 makes the registered agent the statutory recipient for process, notice, or demand. If the corporation fails to appoint or maintain an agent, the Secretary is automatically appointed during the default. Papers are delivered to the Secretary, who immediately forwards a copy by registered mail to the corporation's registered office. Other service methods remain available.

Thirty days without an agent or office—or 30 days without reporting a change, resignation, or office discontinuance—is an administrative-dissolution ground under Mo. Rev. Stat. § 351.484. The Secretary serves written notice, and § 351.486 gives 60 days after perfected service to cure or disprove every ground. Administrative dissolution does not itself terminate an existing agent's authority.

What trips people up

• Corp. 59's generic entity-authorization line does not erase the corporation- specific statute: a board resolution must authorize the change, and the filed statement must recite that authorization.
• The successor's written consent is separate from the corporate signer's execution. The agent signs the form or supplies a separately executed consent.
• The agent's office move is not the corporation's ordinary change route. It requires advance written corporation notice and an agent-signed filing.
• Resignation does not end on filing and does not expressly accelerate when a successor is appointed. The full 30-day statutory period controls.
• The current $10 form reflects a temporary surcharge. The statute schedules that extra $5 to disappear after 2026 unless a later law extends it.

Common questions

Does changing the registered office affect corporate location?

Yes for the chapter's location rule. Mo. Rev. Stat. § 351.375.2 says the corporation's location or residence is deemed to be in the county where its registered office is maintained. That does not answer every venue or tax issue, which may use separate statutes.

Does losing the agent prevent service of a lawsuit?

No. During a failure to appoint or maintain an agent, § 351.380 automatically appoints the Secretary of State for service and directs registered-mail forwarding. The same section preserves other legally permitted service methods.
