Unpaid Invoice Small Claims Court Minnesota: How to File

A client owes you money, your invoices have gone unanswered, and every hour you spend chasing the payment is another hour you are not working. Minnesota Conciliation Court lets you recover unpaid invoices up to $20,000 without hiring a lawyer, and the process is straightforward once you know the steps.

Does Your Claim Qualify?

The Conciliation Court limit is $20,000 for general civil claims. Unpaid invoices for services, goods, or freelance work can qualify. A qualifying consumer credit claim — a seller's claim arising from a personal-property sale or related purchase loan for an individual's personal, family, or household use — has a separate $4,000 limit. The six-year statute of limitations under § 541.05 applies to both written and oral contracts, but the clock starts from the date of breach — typically the day payment was due and not received.

If you are owed more than $20,000, you can reduce your claim to fit the limit, but you permanently forfeit the excess. You cannot split a single contract, transaction, or occurrence into multiple lawsuits to bypass the limit.

Send a Demand Letter First

Minnesota does not generally require a pre-filing demand letter for a contract claim, but sending one can prompt settlement and document your attempt to resolve the dispute. Send it by certified mail, state the amount owed, reference the invoice numbers and dates, and give the client a specific deadline (10 to 14 days is standard) to pay. Keep the tone factual.

This step matters for two reasons. First, a clear demand often gets paid without court involvement — many clients finally act when they see certified mail with a deadline. Second, the demand letter and proof of delivery become evidence that you tried to resolve the dispute before filing, which judges appreciate.

Identifying the Defendant

If your client is an individual, sue them under their full legal name. If the client is a business, search the Minnesota Secretary of State portal to find the exact legal entity name and registered agent.

This matters because a judgment against a trade name that is not a registered entity is unenforceable. "ABC Marketing" might actually be "ABC Marketing Solutions, LLC" — and if you sue the wrong name, you start over.

Filing the Claim

File Form CCT102 in the county where the defendant resides or maintains a principal place of business. Include:

• The amount owed (matching your invoices)
• A clear description of the services or goods you provided
• The dates of the invoices and when payment was due
• Whether any partial payments were made

The filing fee is $70–$80 depending on county.

Service and Deadlines

For claims over $2,500, you handle service yourself — certified mail with restricted delivery, or a professional process server. File Form CCT103 (Affidavit of Service) within 60 days.

For claims at or below $2,500, the court clerk serves the defendant by first-class mail at no extra charge.

For a consumer credit claim, if you and the defendant previously communicated by electronic message, Rule 508(d)(5) also requires you to notify the defendant of the hearing date, time, and place using that type of message. File an affidavit with the court before the hearing identifying whether and how you sent that notice; failure to file it may prevent a default judgment.

Your Evidence Package

Invoice disputes are won with paper trails:

• The original invoices with dates, amounts, and descriptions of work
• The contract or engagement letter (even an email thread confirming the scope and rate qualifies)
• Proof of delivery — emails confirming the work was completed, files delivered, or goods received
• Payment history — statements showing any partial payments and the remaining balance
• Your demand letter and the certified mail receipt
• Communications — emails or texts where the client acknowledged the debt or made excuses

If there is no written contract, oral agreements are enforceable in Minnesota. Your testimony about what was agreed, combined with evidence that you performed the work and the client accepted it, can be enough.

Pre-Judgment Interest

Under § 334.01, you can claim 6% annual interest on the unpaid balance from the date payment was due, even without a written interest clause. If your contract specifies a different rate (up to 8% under Minnesota usury law), use that instead.

After judgment, the 2026 post-judgment interest rate is 4% per annum under § 549.09.

At the Hearing

Present your invoices, proof of work completion, and the communication trail. The judge will want to see that the work was done, the client was billed, and the client did not pay. If the client does not show up, you still testify under oath and present your evidence for a default judgment.

If the client disputes the quality of your work or claims they never approved the charges, your contract (or email confirming scope) and delivery records become critical.
