How to Change Your Registered Agent in Michigan (CD-520, Step by Step)

To change your registered agent in Michigan, you file a Certificate of Change of Registered Office and/or Resident Agent (Form CSCL/CD-520) with LARA’s Corporations Division — either through the MiBusiness Registry Portal or by mail. The form is short, the state fee is nominal, and the change takes effect once LARA endorses the filing. You can also update your agent on your annual statement if the timing happens to line up. That’s the whole mechanic. The part most owners get wrong is everything around the filing: who is eligible to serve, what happens during the gap, and which records need to be updated afterward.

One terminology note before we go further. Michigan doesn’t use the phrase “registered agent” in its statutes. The Michigan Limited Liability Company Act (MCL 450.4101 et seq.) calls it a resident agent, and it calls the address a registered office. The two terms mean the same thing in practice, and LARA staff will understand either one. We’ll use them interchangeably here because that’s how business owners actually talk.

Why Michigan owners switch agents

Almost every change of resident agent traces back to one of these situations:

You listed yourself and moved. Your registered office has to be a Michigan street address where someone is available during business hours. If you served as your own agent and relocated — even across town — the address on file is now wrong, and that’s a compliance problem, not a paperwork nuisance.
You’re leaving Michigan but keeping the LLC. A contractor who moves to Ohio, a landlord who retires to Florida but keeps a Detroit duplex, a trucker who relocates but keeps his Michigan authority — all of them still need a person or company physically in Michigan to accept service of process.
Your current agent is unresponsive or sloppy. Missed mail from LARA, a lawsuit notice that showed up three weeks late, a service that scanned your documents but never emailed them. This is the most common reason people switch, and it’s the most legitimate.
Privacy. Resident agent addresses are public and searchable in LARA’s business entity database. Home-based businesses — photographers, freelancers, consultants — often list their home address at formation and regret it the first time a process server or a mailing-list company finds it.
Your agent resigned or went out of business. Under the LLC Act, a resident agent can resign by filing with LARA. If that happens, you have a limited window to appoint a replacement before your entity is out of compliance.
Price. National providers renew at rates that creep upward every year. A $39 first-year promo that becomes $199 annually is a common story.
Consolidation. If you have three Michigan LLCs with three different agents, putting them all with one provider makes the February compliance season dramatically simpler.

Who can legally serve as your resident agent in Michigan

Before you pick a replacement, confirm they qualify. Under MCL 450.4207, every Michigan LLC must continuously maintain a registered office and a resident agent in this state. The agent may be:

An individual who resides in Michigan, whose business address is the registered office;
A Michigan corporation or LLC; or
A foreign corporation or LLC authorized to transact business in Michigan, with an office in the state.

And the registered office must be a physical Michigan street address. Not a PO box. Not a UPS Store mailbox listed as “Suite 200.” LARA rejects filings that use a PO box as the registered office, and a rejected filing means your change simply hasn’t happened.

You’re allowed to be your own agent. Plenty of owners in Port Huron, Grand Rapids, and Ann Arbor do it without issue. The tradeoff is that your address is public, you must be reliably available during business hours, and a summons can be handed to you in front of a client. Our full guide to starting an LLC in Michigan walks through that tradeoff at formation; the logic is identical when you’re changing mid-stream.

The CD-520 form, field by field

Form CSCL/CD-520 is a one-page certificate. Here’s what it asks for and where owners stumble:

Entity name, exactly as it appears on file. Not your DBA, not your website name. If your Articles of Organization say “Blue Water Cleaning Services, L.L.C.,” write it that way, punctuation included.
Your CID (Customer Identification Number) / entity ID number. This is the identification number LARA assigned when your Articles of Organization were filed. You can look it up free in LARA’s business entity search.
The current registered office address on file. The form asks you to state what’s currently recorded so LARA can match it. Look it up rather than trusting memory — the address you think is on file and the address that actually is are often different.
The new registered office address. Michigan street address, with city and ZIP. If only the agent is changing and the address stays the same, say so.
The name of the current resident agent and the new resident agent.
Signature. An authorized person — typically a member or manager — signs. And here’s the detail that trips people up: if the agent is the one initiating the change of the registered office address (as happens when an agent service relocates), the statute allows the agent to sign instead.

Filing options:

Online through the MiBusiness Registry Portal. This is the fastest route and gives you an immediate confirmation you can save.
By mail to the Corporations Division in Lansing, with a check for the fee.
In person or by fax with an established LARA payment account, if you’re in a hurry.

The state fee for this certificate is small — a few dollars, not a few hundred — but LARA updates its fee schedule periodically, so confirm the current amount at the time you file rather than relying on a number you read in a blog post. For reference on how this fits into your overall spend, our Michigan LLC cost calculator lays out the $50 Articles of Organization fee, the $25 annual statement, and the recurring costs that follow.

The annual statement shortcut

Every Michigan LLC files an annual statement by February 15 with a $25 fee. That statement asks for your current resident agent and registered office — which means if your change happens to coincide with your annual filing, you can update the agent right there instead of filing a separate CD-520.

Two cautions. First, don’t wait for February. If your agent has resigned or your address is already wrong, waiting eight months to fix it leaves you exposed the entire time. Second, the annual statement is not optional maintenance you can skip while you sort out an agent change — Michigan administratively dissolves LLCs that neglect annual statements for two consecutive years, and getting restored is far more painful than staying current. If February deadlines are the thing that keeps slipping, our annual statement filing service puts it on autopilot.

Handling it yourself vs. using a service

	File it yourself	Our $29 agent switch	National provider
What you pay	State fee only	$29 flat, includes the state filing	Often bundled into a $150–$300 annual agent fee
Who prepares CD-520	You	We do	They do
Who verifies current LARA data first	You	We pull your record and match it	Usually assumed from what you type in
Turnaround	Depends how fast you file	We file promptly, expedite available	Varies; support queues are common
Ongoing agent service	You remain your own agent	Michigan address, documents scanned and emailed	Yes, at renewal pricing
Who answers when you have a question	LARA’s phone line	A Michigan-based team	A ticket system

The honest version: if you’re comfortable pulling your entity record, transcribing your ID number correctly, and navigating the MiBusiness Registry Portal, filing CD-520 yourself is genuinely manageable. Our $29 registered agent switch exists for owners who’d rather hand it off, and for owners who want a Michigan street address on the public record instead of their kitchen table. If you want to see how that stacks up against the big national brands on price and renewal terms, we put the numbers side by side on our provider comparison page.

How long it takes, and when you can pay to go faster

Online filings through the MiBusiness Registry Portal are typically processed much faster than mail. Mailed filings move at whatever pace the Corporations Division’s queue allows, and that queue lengthens noticeably in the weeks around the February 15 annual statement deadline.

If you’re on a deadline — a bank needs current records, a licensing board is waiting, a lender’s underwriter flagged a mismatch — LARA offers expedited review for an additional fee, starting at $50 for 24-hour service, with faster same-day and multi-hour tiers at higher prices. For a routine agent change, expediting is usually unnecessary. For a change that’s blocking a closing, $50 is cheap.

The change is effective when LARA endorses the filing, not when you mail it. Plan accordingly.

What to do after the change is on record

The filing is step one. These are the follow-ups that actually prevent problems:

Download the endorsed certificate and store it with your Articles of Organization and operating agreement. Lenders and title companies ask for it more often than you’d expect.
Tell your old agent in writing that they’re no longer serving. If they were a paid service, cancel the subscription so it doesn’t auto-renew next year.
Set up mail forwarding from the old address for at least a few months. Notices sent before the change will still land at the old registered office.
Update everywhere else the address appears — your bank, your insurance carrier, your state licenses, your vendor W-9s. The resident agent address and your business mailing address aren’t the same thing, but they’re frequently entered as the same thing.
Check your public-facing listings. If your registered office address was also your listed business address, correcting one without the other creates a confusing trail. Our Google Business Profile setup covers getting local listings consistent.
Verify in LARA’s entity search about a week later that the new information actually appears. Filings get rejected for small reasons, and rejections aren’t always loudly communicated.

Frequently Asked Questions

Do I have to amend my Articles of Organization to change my resident agent? No. Michigan handles agent and registered office changes through the CD-520 certificate, not an amendment to your Articles. Filing an amendment for this would cost more and accomplish nothing extra.

What happens if my resident agent resigns and I don’t replace them? Your LLC is out of compliance with MCL 450.4207’s requirement to continuously maintain an agent, and you risk missing service of process — which can mean a default judgment in a lawsuit you never knew about. Appoint a replacement promptly rather than waiting for your next annual statement.

Can I use my home address as the registered office? Yes, as long as it’s a Michigan street address where you’re available during normal business hours. Understand that it becomes part of the public record and is searchable by anyone, which is precisely why many home-based owners switch to a commercial agent.

Does changing my agent affect my EIN, bank account, or existing contracts? No. The resident agent is a service-of-process designation; it doesn’t change your LLC’s identity, tax ID, or obligations. If you still need a federal tax ID, our EIN filing service handles that separately.

Is there a deadline to file the change after I move? Michigan expects the record to be accurate continuously, so the practical answer is “as soon as possible.” There’s no grace period that makes a stale registered office acceptable.

If you’d rather not deal with the form, the entity lookup, and the portal, we’ll prepare and file the change for you. Start your $29 registered agent switch and we’ll confirm once LARA has it on record.
