How to Change a Registered Agent in Michigan

A registered agent is one of the most important compliance contacts for a Michigan business. This person or entity receives service of process, official notices, and other legal documents on behalf of the company. If your current registered agent is unavailable, moving, resigning, or no longer the best fit for your business, Michigan gives you a straightforward way to make the change.

This guide explains how to change a registered agent in Michigan for LLCs and corporations, what form to file, how much it costs, and the most common mistakes to avoid.

What Michigan Means by Resident Agent and Registered Office

Michigan uses the term resident agent for the person or entity authorized to receive official documents for your business. The registered office is the physical Michigan location tied to that agent.

In practice, the registered agent and registered office work together as your company’s official point of contact. If the state, a court, or a third party needs to serve legal papers or send formal notices, those communications go to the registered office on file.

Because this address is public and compliance-sensitive, it should be kept current at all times.

When You Should Change Your Registered Agent

Businesses update their registered agent for many reasons, including:

• Your current agent is resigning or unavailable
• You want a more reliable process for receiving legal mail
• You are moving your business operations to a new address
• You want to replace an individual agent with a professional service
• You need to correct outdated contact information on state records
• You want better privacy by keeping your home address off public filings

If your registered agent changes, do not wait until a lawsuit, tax notice, or state reminder is missed. File the update as soon as possible.

Michigan Filing Rule: Use the Correct Change Form

For both Michigan LLCs and Michigan corporations, the usual filing is the Certificate of Change of Registered Office and/or Change of Resident Agent, form CSCL/CD-520.

Michigan also allows certain changes to be updated on an annual filing:

• Corporations can report changes in resident agent or registered office on the annual report
• LLCs can report changes in resident agent or registered office on the annual statement

If you file the change on the annual filing, there is no additional change fee. If you file the separate change form, the state fee is $5.

Who Can Serve as a Michigan Registered Agent

The replacement agent must qualify under Michigan law for your entity type.

For Michigan LLCs, the resident agent must be one of the following:

• A Michigan resident
• A Michigan corporation
• A foreign corporation authorized to transact business in Michigan
• A Michigan limited liability company
• A foreign limited liability company authorized to transact business in Michigan

For corporations, the eligibility rules depend on whether the entity is a for-profit, professional service, nonprofit, or ecclesiastical corporation. The safest approach is to verify that the new agent has a Michigan street address and meets the requirements for the specific entity type before you file.

One important rule applies broadly: the registered office must be a physical Michigan address, not a P.O. box.

How to Change a Registered Agent in Michigan

Here is the practical filing process.

1. Choose the new registered agent

Confirm that the replacement agent is willing to accept the appointment and that the Michigan registered office address is correct. The agent must be available during normal business hours to receive legal and government correspondence.

2. Gather the business details

Before filing, have the following information ready:

• Entity name
• Michigan file number, if available
• Current resident agent name
• New resident agent name
• Registered office street address
• Name and contact information for the filing party

3. File the change with LARA

Michigan’s Corporations Division provides online filing through the MiBusiness Registry Portal. For a change of resident agent or registered office, the FAQ instructions direct filers to log in with a MiLogin for Business account, find the entity, request access, and choose the subsequent document filing option.

If you are filing the standalone change, select CSCL/CD-520 and complete the form.

4. Pay the filing fee if applicable

If you use the separate change filing, the fee is $5.

If you make the change on an annual report or annual statement, Michigan does not charge an additional change fee.

5. Keep your records in sync

After the filing is submitted, update your internal records, operating agreement, corporate records, banking contacts, and any third-party compliance tools so your business uses the same registered agent information everywhere.

LLC vs. Corporation: What Changes and What Does Not

The filing mechanics are similar, but the terminology and underlying rules vary.

Michigan LLCs

LLCs file the change using the state’s resident agent and registered office process. Michigan also requires LLC annual statements, and those statements can be used to update agent information.

Michigan corporations

Corporations use the same general change form, and annual reports can also be used to update resident agent or registered office information.

What does not change

Changing your registered agent does not create a new business entity. It does not change your EIN, your ownership, or your formation date. It only updates the official contact information the state uses for service and notices.

Common Mistakes to Avoid

A simple filing can still cause problems if the details are wrong. Watch for these issues:

• Using a mailing address instead of a physical registered office
• Filing before the new agent has agreed to serve
• Forgetting to update annual report or annual statement records afterward
• Letting a former agent remain on file after resignation
• Choosing an agent that does not meet Michigan eligibility rules
• Missing official notices because the entity did not update its records promptly

If the wrong registered agent remains on file, your business may miss service of process or important state correspondence.

Why the Registered Agent Matters for Compliance

The registered agent is more than a formality. Michigan uses the registered office for official communications tied to the life of the business, including annual filing reminders and service of process.

If your agent cannot reliably receive and forward those documents, the business can face avoidable penalties, missed deadlines, or default issues in a lawsuit.

That is why many business owners choose a professional compliance-focused agent instead of relying on a home address or an individual employee whose schedule may change.

Best Practice for Michigan Business Owners

The cleanest approach is to treat registered agent information as part of your core compliance stack. Review it when you:

• Form a new entity
• Move offices
• Change officers or members
• File annual reports or annual statements
• Replace outside service providers

Keeping the record current reduces risk and prevents avoidable state filing problems.

Final Takeaway

Changing a registered agent in Michigan is usually a quick filing, but accuracy matters. Use the correct state form, verify that the new agent qualifies, keep a physical Michigan registered office on file, and update the information promptly whenever it changes.
