How to Change a Registered Agent in Missouri: Step-by-Step Guide for LLCs and Corporations

A Missouri registered agent is the person or business authorized to receive legal notices, service of process, and official state correspondence on behalf of an entity. If your current agent moves, resigns, stops meeting Missouri requirements, or you simply want a better compliance setup, you should update the registered agent record as soon as possible.

Changing a registered agent in Missouri is usually straightforward, but the filing has to match your entity type and the new agent must be eligible under Missouri law. The key is to use the correct form, gather written consent, and make sure the registered office address satisfies the state’s requirements before you submit anything.

What a Registered Agent Does in Missouri

Your registered agent is the official contact point between your business and the state. In practical terms, the agent receives:

• Service of process in lawsuits
• Official notices from the Missouri Secretary of State
• Certain legal and tax correspondence sent to the entity

Because these documents can affect your business’s legal standing, the registered agent should be reliable, available during normal business hours, and easy to reach at a physical Missouri address.

Missouri requires the registered office to be a real street address where the agent can be served. A P.O. box may only be used together with a physical street address. The state also makes clear that a retail mail-forwarding address, such as a mailbox store, is not a substitute for a compliant registered office.

When You Should Change Your Registered Agent

Businesses change registered agents for many reasons:

• The current agent moved or changed offices
• The current agent resigned
• The business wants to move compliance work to a professional service
• The owner no longer wants to receive service of process personally
• The company is reorganizing or expanding into a more formal compliance setup
• The business missed important notices and wants a more dependable contact point

A change is also wise if your current agent is no longer qualified under Missouri rules. For example, the agent must keep a Missouri business office that matches the registered office address requirement.

Which Missouri Form Do You File?

The form depends on the type of business entity. Missouri uses different forms for different entity categories.

If you file the wrong form, your submission may be delayed or rejected. Before you start, confirm the exact entity type on the Missouri business record.

Step 1: Confirm the New Agent Is Eligible

Missouri does not allow just anyone to serve as a registered agent. The new agent must meet the state’s location and availability rules.

In Missouri, the agent may be:

• An individual who is a Missouri resident and whose business office is identical with the entity’s registered office, or
• A corporation authorized to transact business in Missouri and whose business office is identical with the entity’s registered office

The registered office must be a physical Missouri address. If you use a P.O. box, it must be paired with a street address in the same city.

Before you file, make sure the new agent agrees to serve. Missouri requires the new registered agent’s written consent to accompany the statement of change.

Step 2: Gather the Information You Will Need

Before completing the form, collect the following details:

• The entity’s full legal name
• The charter number or other state identifier
• The current registered agent name
• The new registered agent name
• The current registered office address
• The new registered office address, if it is changing
• The new agent’s written consent or signature
• The name and title of the person authorized to sign for the entity

Taking a few minutes to verify this information helps prevent avoidable filing errors. The Missouri Secretary of State will expect the document to match the entity’s record and the new agent’s information to be complete.

Step 3: Complete the Filing Form Carefully

For corporations and LLCs, Missouri’s Corp. 59 form is the standard statement of change. The form is designed to be filled out online, then printed and signed for submission.

On the form, you will typically identify:

• The business entity name
• The present registered office before the change
• The new registered office, if applicable
• The present registered agent
• The new registered agent

The form also requires the new agent’s authorization. Missouri allows the new agent’s signature to appear directly on the form or on a separate written consent attached to the filing.

Keep the addresses consistent. The registered office and the business office of the registered agent must be identical after the change.

Step 4: File the Form and Pay the Correct Fee

For most Missouri entities, the fee to change the registered agent or office address is $10.

Limited liability partnerships are different. Missouri’s fee schedule lists:

• $37 to change the registered agent and registered office at the same time
• $22 to change the registered agent office only
• An additional $7 for each additional LLP affected by the filing

If you are mailing the filing, Missouri’s instructions direct checks to the Secretary of State. Electronic payments may also involve a convenience fee, depending on the filing method used.

Always verify the fee before submitting, especially if your entity type falls under a separate chapter of Missouri law.

Step 5: Update Your Internal Records

The state filing is the legal step, but your business should also update its own records after the change.

Review and revise:

• Internal compliance files
• Operating agreements, bylaws, or governance records if they reference the old agent
• Banking and vendor records where the registered agent is listed as a contact
• Insurance files
• Legal counsel and accountant contact records
• Any licenses or registrations that rely on entity contact information

Missouri only requires the Secretary of State filing, but internal consistency helps prevent missed notices later.

Special Notes for Other Missouri Entity Types

If your business is not a corporation or LLC, make sure you use the right form before filing.

• Limited partnerships use LP 9
• Limited liability partnerships use LLP 9
• Cooperative associations use CA 59

These filings may have different instructions and fee amounts. Checking the exact form first can save time and avoid a rejected submission.

Can You Change the Registered Agent During a Regular Report?

In some Missouri filings, registered agent information can be updated while filing an annual or biennial registration report if the system and entity are eligible. If that option is available for your entity, it may be a convenient time to make the change.

Even then, the same basic requirements still apply: the new agent must be eligible, consent must be provided, and the record must reflect a valid Missouri registered office.

What Happens If You Do Not Maintain a Registered Agent?

Failing to maintain a compliant registered agent can cause serious problems.

Possible consequences include:

• Missed service of process
• Missed state notices
• Loss of good standing
• Administrative dissolution or cancellation, depending on entity type
• Delays in legal or business matters that depend on proper state records

If your current agent is no longer available, do not wait. File the change promptly so the entity stays compliant.

Can You Change the Registered Agent Yourself?

Yes. Many business owners handle the filing themselves.

If you want a more hands-off approach, you can also use a professional registered agent service. That can help reduce the chance of missed notices and keep compliance responsibilities organized.

Common Mistakes to Avoid

A simple filing can still go wrong if the details are rushed.

Avoid these mistakes:

• Using the wrong form for the entity type
• Listing a P.O. box without a physical street address
• Failing to get the new agent’s written consent
• Forgetting to update the registered office after the agent change
• Entering an address that does not match the agent’s actual business office
• Filing before confirming the new agent is qualified to serve in Missouri

A clean filing is faster than a corrected one.
