How to Change the Registered Agent for a Missouri LLC

A registered agent isn't a set-it-and-forget-it decision: situations change, and Missouri LLCs update their agent regularly. The most common reasons:

• Moving off your home address. Many owners name themselves at formation to save money, then realize their home address is now public and searchable. Switching to a commercial agent gets that address out of the public record.
• The current agent resigned or stopped responding. A friend or employee who agreed to serve may move away, leave the company, or simply stop forwarding mail. That's a compliance problem you have to fix.
• You outgrew the DIY setup. As a business grows, being the person a process server looks for at your own office stops making sense. A service handles it without you thinking about it.
• You're consolidating. If you own several entities, putting them all under one commercial registered agent keeps everything in one place.
• The agent's address changed. Even if you keep the same agent, a move means the state's record has to be updated.

Whatever the reason, the fix is the same: file Form Corp 59, the Statement of Change of Registered Agent and/or Registered Office, with the Missouri Secretary of State so the public record reflects your current, valid agent. The filing fee is $10.

Changing your agent is quick, but a couple of things have to be lined up first.

The incoming agent must consent

Your new registered agent has to agree to serve. Form Corp 59 builds this in: the new agent signs the form or you attach the agent's written consent. If you're hiring a commercial service, the service provides that signature or consent as part of signing up. If you're naming an individual, they need to know and accept the responsibility before you file.

The new agent must meet Missouri's requirements

Whoever you're switching to has to satisfy the same rules as any Missouri registered agent under RSMo 347.030:

• A registered office in Missouri that's identical with the agent's business office (a P.O. box only works if a physical street address in the same city is listed too)
• Either an individual Missouri resident, or a domestic or foreign corporation authorized to do business in Missouri
• Not the LLC itself; Form Corp 59's instructions note that the entity can't act as its own agent

Your LLC needs to be in good standing

Make sure your entity is active with the Secretary of State before you file the change. If your LLC has somehow fallen out of good standing, sort that out first so the change filing goes through cleanly.

Missouri handles registered agent changes through the Secretary of State, Corporations Division, using Form Corp 59 (revised 01/2025). The fastest path is Missouri Business Filings, the state's online system; the Corporations Division also posts the PDF form on its website. The fee is $10.

The information you'll provide

• Your LLC's exact legal name as it appears on record
• Your Missouri charter or entity number (find it via the business entity search)
• The name of the new registered agent
• The new registered office (the agent's physical Missouri street address)
• The new agent's signature on the form, or a written consent attached to it

Once the state processes the filing, the change takes effect and the public record shows your new agent. The Secretary of State says many online filings are processed immediately after submission. If you hired a commercial registered agent service, they usually prepare and submit this filing for you as part of onboarding, so you may not have to touch the form at all.

Confirm it went through

After filing, look your LLC up in the business entity search to confirm the new agent and address appear on the record. It's a thirty-second check that saves you from assuming a change stuck when it didn't.

The one thing you don't want when changing agents is a window where no valid agent is on file. Under Chapter 347 of the Revised Statutes of Missouri, your LLC has to maintain a registered agent continuously: a lapse leaves you out of compliance and, more importantly, means a lawsuit could be served on an address nobody is watching.

Line up the new agent before releasing the old one

Don't resign your current agent, cancel a service, or move out of an address until the replacement is in place and the change is filed. Keep the old arrangement live until you've confirmed the new agent shows on the state record. That overlap costs nothing and closes the gap entirely.

Watch for a resigning agent

If your agent is the one initiating the change (resigning on you), you're on a clock. A resigning agent files a resignation with the state, and you need to name a replacement before your coverage lapses. This is exactly the scenario that catches owners off guard, so if you get notice that your agent is stepping down, treat naming a new one as urgent.

Update your own records too

Once the change is official, make sure any place that lists your registered agent (your operating agreement's records, your internal compliance notes) reflects the new agent so nothing points at the old one.

If you're switching your Missouri LLC's registered agent to us, we make the transition painless. We provide the compliant Missouri registered office address, sign as the incoming agent, and prepare and file Form Corp 59 with the Secretary of State on your behalf. You give us your entity name and charter number, and we handle the paperwork.

From there, we serve as the continuous point of contact for legal service and official state mail, accepted at our monitored Missouri address, scanned, and uploaded for you promptly. Your personal address comes off the public record in the process, and process servers come to us rather than to you.

We're a registered agent and filing service, not a law firm, so we don't give legal advice or represent your LLC in litigation. What we do is make the switch clean, keep your appointment valid, and make sure that when something legally important arrives, it actually reaches you in time to respond.
