Change the Resident Agent for a Michigan Corporation

Michigan requires your corporation to maintain an accurate resident agent and registered office at all times, so an out-of-date record isn't just untidy — it's a compliance problem. Several common situations force a change.

The usual triggers

• You hired a commercial resident agent. Many owners start out as their own agent, then switch to a service to get their home address off the public record and stop having to be present for served documents.
• Your current agent resigned. A resident agent can resign by notifying you and the state. If that happens, you must name a replacement or the corporation falls out of good standing.
• The agent moved. If the registered office address changes, the record has to reflect the new Michigan street address.
• You're switching providers. Moving from one commercial agent to another — often for better service or pricing — requires updating the record.
• An individual agent left the company or the state. If your agent was an employee who quit, or a person who moved out of Michigan, they no longer qualify.

The key principle: Michigan wants a continuous, correct agent on file. A gap — even a short one — leaves the corporation exposed, because a lawsuit served during that gap may go unanswered.

The change of resident agent for a Michigan corporation is handled by the Corporations Division through a Certificate of Change of Registered Office and/or Resident Agent — commonly LARA Form CSCL/CD-520. You can file it online through the MiBusiness Registry or by mail to the Corporations Division. LARA charges a modest fee to record the change; check the current fee schedule.

What the filing needs

• The corporation's exact legal name as it appears on file, and its LARA entity ID
• The name of the new resident agent
• The new registered office street address in Michigan (a P.O. box alone won't be accepted)
• Authorization by an officer of the corporation

The order of operations matters

If you're moving to a commercial resident agent, line up the new agent first and confirm they've agreed to serve before you file — you want the new agent in place the moment the old one is replaced, with no gap. A reputable service will often prepare and submit the CSCL/CD-520 for you as part of onboarding, which removes the risk of a mismatched or incomplete filing.

Processing

Once LARA accepts the change, the new resident agent and registered office appear on the public record. Routine processing is typically quick for a simple agent change, though it's still subject to the Corporations Division's current workload.

Sometimes the agent stays the same but the address changes — you moved offices, or your agent relocated within Michigan. This is still a filing, because the registered office address on record must always be current.

Two flavors of address change

• You are your own agent and moved. File the change to update the registered office to your new Michigan street address. Don't skip this because the move felt minor; the state record and any served documents route to the address on file.
• Your commercial agent changed its own address. A commercial agent that relocates typically files a consolidated update covering all the entities it represents, so you usually don't have to do anything — but confirm with your provider that your corporation was included.

A stale registered office is one of the quieter ways corporations drift out of compliance. Service of process and state mail go to the address on record, so if that address is wrong, you may never see a lawsuit or a dissolution warning until it's too late to respond.

Agent changes get bounced for a handful of predictable reasons. Knowing them in advance saves a round trip.

• Using a P.O. box for the registered office. Michigan requires a physical street address; a box alone is rejected.
• A name that doesn't match the record exactly. The corporate name on the CSCL/CD-520 must match LARA's records precisely, including punctuation and the corporate indicator.
• The new agent hasn't actually agreed. Naming an agent who hasn't consented creates problems; confirm acceptance before filing.
• Leaving a gap. Removing the old agent before the new one is effective creates a window with no agent of record. Coordinate the timing.
• Forgetting the corporation was already delinquent. If the corporation is out of good standing for a missed annual report, resolve that too; changing the agent alone doesn't cure a separate delinquency.

If you're switching your corporation's resident agent to Mainstay Filing, we manage the whole transition. We confirm your corporate details against the LARA record, prepare the Certificate of Change of Registered Office and/or Resident Agent, and file it with the Corporations Division so our Michigan office becomes your registered office of record.

We coordinate the timing so there's no coverage gap — our agency takes effect as your prior arrangement ends, and service of process starts routing to us immediately. From then on, anything served on the corporation reaches our Michigan office and gets forwarded to you promptly, and we keep you ahead of the May 15 annual report deadline.

If you simply need to update an address because you moved, we can prepare that filing too. What we can't do is give legal advice about your specific situation — but we can make sure the state record is accurate and that the corporation never has a moment without a valid agent on file.
