If you’re asking how to sue a dispensary in Michigan, you’re usually dealing with a serious business problem: an unpaid invoice, underpayment, or a contract dispute that hasn’t improved despite reminders and deadline extensions. Cannabis litigation has its own wrinkles (especially because cannabis remains illegal federally), but Michigan has a mature, heavily regulated market—and that framework can help you approach a dispute in a structured way.
This guide walks through a practical, cannabis-aware roadmap using Michigan-specific regulatory context and the litigation steps outlined by cannabis industry specialists.

The date the buyer was supposed to pay: the invoice due date, or the missed installment date on a note or payment plan. If several invoices are unpaid, use the oldest.
Michigan's UCC gives 4 years from the missed payment for sale-of-goods claims. The original sales contract can shorten this to as little as 1 year, so check your terms.

How are Michigan dispensaries regulated, and why does it matter before you sue?
Michigan’s adult-use market is large and tightly regulated. Michigan has generated more than $16 billion in combined cannabis sales and over $2.2 billion in total tax revenue to date, and the licensed market is regulated by the Michigan Cannabis Regulatory Agency (CRA) (Cova: Michigan Cannabis Dispensary Laws & Licensing). In a dispute, that matters because your opposing party is likely operating within a licensing and compliance ecosystem that influences recordkeeping, contracting, and risk.
Licensing and location rules are also structured at both state and local levels. For example, a dispensary generally cannot be within 1,000 feet of a K–12 school (with municipalities able to adjust the setback), and municipalities can opt out of adult-use retail entirely—meaning local authorization and zoning approval are central to operations (Cova). Michigan also uses a two-step application process administered by the CRA (Cova).
Why does that matter to you? Because disputes with dispensaries often involve documents and compliance records that intersect with licensing (e.g., entity names, operating locations, and internal procedures). Understanding that the CRA sits in the background helps you and your counsel frame requests and timelines realistically.
What Types of Disputes Commonly Lead to Suing a Dispensary?
Cannabis industry collection and litigation resources often focus on one common scenario: you performed, delivered, or contracted for something—and the dispensary still hasn’t paid (or hasn’t paid correctly). CannaBIZ Collects specifically describes the “time to sue” moment as when a business has already tried “negotiating, extending deadlines, and sending polite reminders” but remains “unpaid or under-compensated” (Ultimate Guide to Suing a Dispensary | CannaBIZ Collects).
To stay focused and effective, anchor your dispute around what you can document. In practice, that often means:
- Outstanding debt supported by invoices, purchase orders, or written agreements
- Under-compensation where payment terms exist but weren’t followed
- Contract breakdowns where the agreement (and any dispute clause) controls the next steps
If you’re unsure whether your situation fits this pattern, the most useful first question is: Do I have a clear written agreement and a clear dollar amount in dispute? CannaBIZ Collects emphasizes that whether litigation is “worth pursuing” depends on “the specific circumstances,” including whether “the amount in dispute is significant” and whether you have “a strong contract” (CannaBIZ Collects).
How long do you have to sue a Michigan dispensary?
Michigan generally allows 6 years to sue for breach of a written or oral contract, such as unpaid services (MCL 600.5807). For unpaid invoices for goods, the Uniform Commercial Code allows 4 years from the missed payment, and your sales contract can shorten that to as little as 1 year (MCL 440.2725). The calculator above estimates your deadline and builds a collections timeline. Confirm the date with a Michigan attorney, because your contract and the facts of your account can change it.
What are the steps to sue a dispensary in Michigan?
Most people asking this want a clear sequence. The steps below track closely to the cannabis-specific process laid out by CannaBIZ Collects, with Michigan venue realities in mind.
1) Start with a formal demand letter
CannaBIZ Collects describes the demand letter as your “first formal move.” It should outline your grievances, detail the debt or issue, and give the dispensary a final opportunity to resolve the issue before escalation (CannaBIZ Collects).
Actionable approach (without overcomplicating it):
- State the parties and the agreement (use the legal business names you contracted with).
- List the specific invoices, dates, and amounts you contend are unpaid or underpaid.
- Set a clear deadline to pay or respond.
- Say what happens next (mediation/arbitration if required, otherwise filing suit).
2) Check for mediation or arbitration language in your contract
Cannabis contracts often include dispute-resolution clauses. CannaBIZ Collects explains that if “mediation or arbitration fails—or if there’s no such clause in your contract—it’s time to proceed with a lawsuit” (CannaBIZ Collects). That’s your cue to read your agreement carefully before you file.
If your contract requires an alternate process first, treat that requirement as part of your strategy—not a detour. It can also create leverage if the dispensary knows you’re prepared to follow the contract all the way through.
3) File in the right court (usually state court)
CannaBIZ Collects notes that you’ll “typically” want to file in state court, particularly in the state where the dispensary operates. The reason is straightforward: because cannabis remains illegal at the federal level, “many federal courts will be reluctant to hear your case,” making state courts your best bet (CannaBIZ Collects).
Choosing the venue in a cannabis dispute is not just a technicality. It can decide whether your case is heard at all.
4) Prepare for discovery (and cannabis-specific complications)
After filing, litigation often enters discovery—the pre-trial exchange of information. CannaBIZ Collects explains that discovery “can get complicated,” especially if a dispensary is not forthcoming with “financial records or licensing documentation,” and that you’ll want an attorney who understands cannabis industry intricacies and “can ask the right questions” (CannaBIZ Collects).
From a practical standpoint, that means you should be ready to organize what you already have (contracts, invoices, email trails, delivery confirmations) and anticipate that the other side’s documentation may tie into licensing and compliance realities.
“At the end of the day, the best choice depends on the specific circumstances of your case.” (CannaBIZ Collects)
Should you sue in state or federal court?
Michigan cannabis businesses do litigate important issues in Michigan forums, including lawsuits involving state policy. For example, WWMT-TV reports that Michigan’s marijuana industry filed (and then filed again) to fight a 24% wholesale tax, and that an earlier lawsuit is “heading to trial” in September at the Court of Claims in Lansing (WWMT-TV report). This is not the same as a vendor vs. dispensary debt case, but it’s a real-world signal that Michigan cannabis disputes are actively litigated in state venues.
By contrast, CannaBIZ Collects highlights that many federal courts are reluctant to hear cannabis disputes due to federal illegality (CannaBIZ Collects). The takeaway is to treat venue selection as a core strategy decision—one you should align with counsel who understands cannabis-industry risk.
When is a lawsuit not the best way to get paid?
Suing is not always the fastest or most efficient way to get paid. CannaBIZ Collects frames the decision plainly: if the amount is significant and your contract is strong, a lawsuit may be worth it—but if you want a more streamlined process that avoids “the pitfalls of litigation,” a cannabis-focused debt collection agency may be the better option (CannaBIZ Collects).
Use that as a decision filter:
- Choose litigation when documentation is strong, the balance is meaningful, and you’re prepared for formal discovery and timelines.
- Consider streamlined recovery when speed, cost control, and a structured collection process matters more than litigating every issue.
Even if you plan to sue, a well-crafted demand letter (and any contract-required mediation/arbitration) can resolve the dispute sooner, or at least sharpen the issues before filing (CannaBIZ Collects).

How do CRA rules affect a dispute while it’s ongoing?
Michigan cannabis businesses operate under CRA rules that can create additional pressure during “significant events.” The Michigan Bar Journal warns that taking time to learn the rules is “worth the investment,” and when a significant event occurs, licensees should reach out to counsel with cannabis expertise to analyze the rules, navigate the notice process, and prepare appropriate notice—because “what you don’t know may indeed hurt you” (Michigan Bar Journal (State Bar of Michigan)).
The Bar Journal article cites statutory sections including MCL 333.27206, MCL 333.27957, and MCL 333.27958 in its discussion of CRA notice requirements (Michigan Bar Journal). If your dispute could trigger reporting, ownership, operational, or other regulatory considerations, that’s a strong argument for cannabis-experienced legal guidance.
Operational compliance expectations can also be relevant context. For example, dispensary owners are required to implement internal policies and keep training and standardized point-of-sale procedures on-site (Cova). While that doesn’t prove your claim, it underscores why cannabis disputes can involve more documentation than a typical retail disagreement.
In other words: yes, you can pursue legal remedies—but you’ll do it more safely if you respect the regulated nature of the business environment around the dispensary.
Frequently Asked Questions
How do I sue a Michigan dispensary that won’t pay my invoices?
A cannabis-focused pathway is to start with a formal demand letter detailing the debt and giving a final opportunity to cure, then follow any contract-required mediation/arbitration, and if that fails, proceed to file—typically in state court where the dispensary operates (CannaBIZ Collects).
Can I just file in federal court?
CannaBIZ Collects notes that because cannabis is illegal at the federal level, many federal courts will be reluctant to hear cannabis cases, which is why state court is often the recommended venue (CannaBIZ Collects).
What should I expect during discovery?
Discovery is the pre-trial exchange of information, and in cannabis disputes it can become complicated if the dispensary resists turning over financial records or licensing documentation. CannaBIZ Collects recommends working with an attorney familiar with cannabis-industry specifics to ask targeted questions and push the process forward (CannaBIZ Collects).
Are cannabis businesses in Michigan actually suing over major issues?
Yes. WWMT-TV reports that Michigan’s cannabis industry has filed lawsuits challenging a 24% wholesale tax, including a case reported as heading to trial in September in the Court of Claims in Lansing (WWMT-TV). While that’s not a private debt case, it shows state-level cannabis litigation is active.
When should I use a debt collector instead of suing?
According to CannaBIZ Collects, if your dispute is significant and you have a strong contract, litigation may be worth it. But if you want a more streamlined approach that avoids litigation’s pitfalls, a cannabis-focused debt collection agency may be the better option (CannaBIZ Collects).
If you’re still weighing your options, consider starting with the demand letter step first—it’s the cleanest way to formalize the dispute and clarify whether escalation is truly necessary (CannaBIZ Collects).
