A Michigan LLC operating agreement is the document that decides how your company splits money, who gets to make decisions, and what happens when a member leaves. Michigan does not require you to have one — but the state has already written the rules that apply if you do not, and for most partnerships those defaults are not what anyone had in mind.
This page explains what the Michigan Limited Liability Company Act says, with the section behind each point, and gives you a free template in PDF and Word.
The short answer
Michigan does not require an LLC to adopt an operating agreement. What it does is supply defaults. Two of them matter most: MCL 450.4304(2) requires the unanimous approval of the members before anyone can take a distribution at all, and MCL 450.4303 then splits whatever is distributed in equal shares to all members — regardless of who put in the capital.
The default rules that surprise people
MCL 450.4303(1) is short and worth reading closely:
Work through what that means. Two people form a Michigan LLC. One contributes $90,000, the other $10,000. They never sign an operating agreement because the business is small and they trust each other. Under MCL 450.4303, distributions are allocated in equal shares — fifty-fifty — not 90/10. The contributions basis in subsection (1)(a) reaches only allocations before 1 July 1997; after that date it survives solely for companies formed earlier that were already using it, and only until an operating agreement changes it.
And it does not stop while the company is trading. On winding up, MCL 450.4808(1)(c) sends the remaining assets, once creditors are paid, to the members “in accordance with their shares of distributions as determined under section 303” — equal shares again. Without an operating agreement, the member who put in $90,000 does not take it back off the top when the company closes either.
There is a second default that bites first, and it changes the practical picture. Under MCL 450.4304(2), where no operating agreement addresses a member’s right to a distribution before withdrawal or dissolution, “the unanimous approval of the members is required for any distribution to that member”. So in the example above the $10,000 member cannot simply help themselves to half — but neither member can take anything out without the other agreeing. The real default is not an unfair split. It is deadlock, followed by an equal split of whatever both sides eventually release.
In Michigan, an operating agreement is a written document
This is a definitional point that catches people out. MCL 450.4102(2)(r) defines the term:
Some states recognize oral or implied operating agreements. Michigan’s definition says written. A handshake understanding about profit splits is not an operating agreement under this Act, so the Act’s defaults are what the company runs on. Whether that understanding still binds the two people as an ordinary contract between them is a separate question, and not one the LLC Act answers. The definition also sweeps in any provision of your articles of organization dealing with the company’s affairs — so what you filed at formation is already part of the picture.
It is not just paperwork: the agreement can decide personal liability
An operating agreement is often described as an internal formality. MCL 450.4308 shows it is more than that. A member or manager who votes for or assents to a distribution that violates the operating agreement — or that breaches the solvency limits in MCL 450.4307 — can be personally liable, jointly and severally, to the company for the excess.
The statute attaches a condition, and it matters: that liability applies only “if it is established that the member or manager did not comply with section 404” — the standard in MCL 450.4404 of acting in good faith and with the care an ordinarily prudent person would use in a like position. It is not automatic. A claim under this section is barred after two years.
The section also sets a presumption that catches the passive: a member entitled to participate in the decision is presumed to have assented unless they vote against it or file a written dissent within a reasonable time after learning of it. Staying quiet is not neutrality.
What members can demand from the company
MCL 450.4503 gives every member information rights that exist whether or not you have an agreement:
- On written request, a copy of the company’s most recent annual financial statement and its most recent federal, state and local tax returns.
- On reasonable request, true and full information about the company’s current financial condition.
- On reasonable written request and during ordinary business hours, the right to inspect and copy the records the company must keep, at the member’s own expense.
A well-drafted agreement builds on these rather than pretending they do not exist — for example by fixing a reporting calendar so nobody has to make a formal request in the first place.
What to put in a Michigan operating agreement
| Provision | Why it matters in Michigan |
|---|---|
| Capital contributions | Record what each member actually put in. Without this, MCL 450.4303 splits distributions equally. |
| Allocation of distributions | The clause the defaults hit hardest. State the percentages explicitly. |
| When distributions can be taken | Without it, MCL 450.4304(2) requires unanimous approval for any distribution. |
| Management structure | Member-managed or manager-managed, and who can bind the company. |
| Voting thresholds | Which decisions need unanimity and which a majority. |
| Transfer restrictions | Whether a member can sell their interest to an outsider, and on what terms. |
| Exit and dissolution | What happens on death, withdrawal or deadlock — and how the interest is valued. Note MCL 450.4808 on winding up. |
Single-member LLCs
If you are the only member, an operating agreement can feel pointless — there is nobody to agree with. Michigan’s definition anticipates the case: it covers “a written agreement by the member of a limited liability company that has 1 member” (MCL 450.4102(2)(r)), so a one-member agreement is a recognized instrument under the Act rather than a contradiction. The other common reasons sit outside the statute: many banks and payment processors ask to see one when you open a business account, and members use it to document how the company’s affairs are kept separate from their own. Neither is a Michigan legal requirement, and the Act does not make the agreement a condition of anything.

Frequently asked questions
Is an operating agreement required for a Michigan LLC?
No. Michigan does not require one. But MCL 450.4304(2) then requires unanimous approval for any distribution, and MCL 450.4303 splits what is distributed in equal shares to all members, whatever each contributed.
Is there a sample Michigan LLC operating agreement I can work from?
Yes — the generator and the PDF and Word files above are a sample Michigan LLC operating agreement form you can fill in and adapt. Michigan does not publish an official form, because the agreement is never filed with the state.
Does a Michigan LLC operating agreement have to be in writing?
Yes, by definition. MCL 450.4102(2)(r) defines an operating agreement as a written agreement. An oral understanding does not meet the statutory definition, so the Act’s defaults govern the company.
Does it need to be filed with the state?
No. The operating agreement is an internal document. What gets filed at formation is the articles of organization — and provisions in those articles concerning the company’s affairs form part of the operating agreement under the statutory definition.
Does a single-member LLC in Michigan need one?
Not as a legal requirement. The statutory definition expressly contemplates an agreement by the single member of a one-member LLC, and banks commonly ask to see one when you open a business account — that second point is banking practice, not a Michigan rule.
Can members be personally liable over an operating agreement?
Yes, in one specific situation. Under MCL 450.4308, a member or manager who votes for or assents to a distribution that violates the operating agreement can be personally liable to the company for the excess — but only where it is established that they did not meet the standard of conduct in MCL 450.4404. Assent is presumed unless they vote against it or file a written dissent.
Can we change the agreement later?
Yes, by the amendment procedure the agreement itself sets out. Agree that procedure while everyone is still on good terms; renegotiating an allocation after the money has arrived is a different conversation.
