Missouri Small Claims Court: How to File and Win (2026)

Missouri small claims court handles money disputes up to $5,000. You file a Petition for Small Claims at the circuit court in the right county. You pay a filing fee, about $20.50 to $35.50 in most counties. The clerk serves the other side by certified mail for $10. Your hearing comes 30 to 60 days later. No jury. No strict rules of evidence. You tell the judge what happened and show your proof.

This guide runs on Missouri's actual statutes and the official 2026 fee schedules from Jackson County and St. Louis County. Fair warning: most guides get a few things wrong here. The interest rate on your judgment. Who is banned from filing. What an appeal really does. We fix all of that below.

How Missouri small claims court works

Missouri doesn't run a separate small claims courthouse. A circuit court judge sits as the small claims court. Every county has one. Same building, faster lane.

The court hears money claims only, up to $5,000. That cap doesn't count interest or court costs (RSMo 482.305). Contract fights and tort claims both qualify.

What it can't do: evictions, divorce, or orders that force someone to act. It also can't make someone return your stuff. If you want property back instead of money, you need the regular civil docket.

Now two rules most guides skip. Both come from RSMo 482.330.

First, you can't file more than 12 small claims cases in Missouri in one calendar year. You sign a sworn statement about it every time you file. Blow past the limit and the court tosses your case.

Second, assignees are banned. If a debt was sold or signed over to someone else, the new owner can't collect it in small claims. That one rule keeps debt buyers out of this court. It exists for regular people with their own disputes. That's good news if you're the one filing.

What it costs to file

Filing fees change by county. Not by a little. Here are real numbers pulled from official fee schedules and court sites:

So in Jackson County, suing one person with sheriff service runs $73.50 all in. Certified mail drops that to $37.50. Your county will differ. Call the circuit clerk and ask for the exact number before you go.

Can't afford the fee? Ask for the in forma pauperis motion. That's the fee waiver. The court looks at your income and can waive filing and service costs.

One quirk from Jackson County's own booklet: the clerk wants exact change for cash. And they only accept personal checks numbered over 500. Yes, really. Bring a money order and skip the drama.

How to file small claims in Missouri: 8 steps

Step 1: make sure your case fits

Small claims works for one thing. Someone owes you money and won't pay. Unpaid loans. Security deposits. Bad contractor work. Property damage. Unpaid invoices for your side work.

Owed more than $5,000? You can trim the claim and waive the rest. A $6,200 claim becomes a $5,000 claim, but you keep the fast docket and the low fee. Or file the full amount in the circuit court's regular division, which costs more and moves slower. Run the math with our guide to what it costs to sue someone.

Step 2: check your deadline

Every claim has a statute of limitations. Miss it and your case dies, no matter how strong your proof is.

Missouri is generous here:

Five years for personal injury is about the longest window in the country. Most states give you two or three. Don't use all of it. Proof fades. Witnesses move. File while the story is fresh.

Step 3: pick the right county

Under RSMo 482.330, you can file in a county where:

• a defendant lives, or
• you live, if the defendant can be found there, or
• the deal or the damage happened.

Kansas City makes this tricky. The city sprawls across more than one county. Jackson County alone runs two courthouses. The Kansas City side files at 415 E. 12th Street, third floor. The eastern side (Independence, Lee's Summit, Blue Springs, Raytown) files at 308 W. Kansas Avenue in Independence. North of the river, you're likely in Clay or Platte County instead.

St. Louis is two separate worlds. St. Louis City cases go to 10 N. Tucker Boulevard downtown. St. Louis County cases go to 105 S. Central Avenue in Clayton. Kirkwood and Florissant are County, not City. File in the wrong one and you start over.

Springfield area? Greene County Circuit Court at 940 Boonville Avenue.

Step 4: fill out two forms

The Petition for Small Claims is your actual claim. Who you're suing, how much, and a short plain-English story of why they owe you. The Filing Information Sheet is a cover form the clerk uses to sort your case. Both are free at courts.mo.gov or at the clerk's window. The Missouri Bar also puts out a free small claims handbook, and many county court sites host a copy. It's worth the read.

If you're suing a business, get the name exactly right. Search the Missouri Secretary of State's business records for the legal name and the registered agent. "Mike's Auto" might really be "Mike's Auto LLC" with an agent across town. Suing a partnership? Jackson County's booklet is blunt about this: you have to name and serve each partner. Sloppy names get cases dismissed. Our guide to suing a corporation walks through it.

Step 5: file in person and pay

Take your forms to the circuit clerk and pay the fee. And here's a correction you won't find in older guides: you generally can't e-file your own small claims case in Missouri. The state's e-filing system is built for attorneys. Case.net is for looking cases up, not filing them. Jackson County even asks you not to mail your petition. Go in person. You leave with a receipt showing your case number, hearing date, and division. Keep it.

Step 6: serve the defendant

The other side has to get official notice. Missouri gives you three routes:

• Certified mail. The clerk mails it. $10 per defendant. Cheapest, but it fails when people dodge their mail.
• Sheriff. A deputy hand-delivers it. $46 in Jackson County, $55 in Greene. Out of county, call that county's sheriff for their rate.
• Private process server. You pay their fee directly, and you need a motion and a signed court order first.

Jackson County's booklet flat-out recommends personal service to avoid delays. If service fails, ask the clerk for an alias summons and try again with a better address or method.

Check Case.net about a week before your hearing to confirm service happened. No service means no hearing. For the full playbook, read how to serve court papers.

Step 7: build your proof

Bring everything that tells your story:

• The contract, lease, or estimate
• Receipts, invoices, and bank records
• Photos of the damage or the bad work
• Texts, emails, and voicemails
• Your demand letter and the mailing receipt
• Witnesses, subpoenaed if they won't come on their own

Print your phone photos. Jackson County requires photos to be printed before you walk in. No judge wants to scroll your phone at the bench.

Make three copies of everything. One for the judge, one for the other side, one for you. Put it all in date order and know your dollar amount cold. More prep tips in how to prepare for small claims court.

Step 8: show up and keep it short

Most hearings run 15 to 30 minutes. You talk first. Walk the timeline, hand up your proof, give your number. The other side goes next. The judge asks questions and rules, sometimes on the spot.

If the defendant was served and doesn't show, ask for a default judgment. You still present your proof, but it's quick.

If you don't show, your case gets dismissed. And in Jackson County, a case dismissed because you failed to appear can't be refiled in small claims. One missed alarm can end the whole thing. Set three.

On the other side of this? Here's what to do if someone sues you.

Suing your landlord? Know the deposit rules

Deposit fights are the bread and butter of Missouri small claims, and the law tilts your way. RSMo 535.300 sets the rules. A landlord can't take a deposit bigger than two months' rent. After you move out, they have 30 days to return it or send an itemized list of damages with the balance.

Blow the deadline or keep money wrongfully, and the court can award you twice the amount wrongfully withheld. A $1,400 deposit held back in bad faith becomes a $2,800 claim.

Here's the part almost nobody uses: you have the legal right to attend the move-out inspection. The landlord has to give you reasonable written notice of the date and time. Show up with a camera. It's the cheapest insurance you'll ever get. Full playbook: how to get your security deposit back.

The appeal rule that favors winners

Either side can demand a trial de novo within 10 days of the judgment (RSMo 482.365). That means a brand new trial in front of a different judge, run under regular circuit court rules. The 10 days includes weekends.

The fee depends on the county. St. Louis County charges $45. Jackson County charges $82, which is three times its own filing fee.

Now the part nobody explains. Filing an appeal does not freeze your right to collect. To stop collection, the loser has to post a bond with sureties covering the full judgment plus costs. Most small claims losers never do that. So if you win and the other side mutters about appealing, your judgment still has teeth while the clock runs.

One more wrinkle. If the defendant appeals, the law lets you amend your claim above $5,000, up to the circuit court's limit. Their appeal can raise their own risk.

How to collect after you win

The court doesn't collect for you. Nobody mails you a check. You have to go get it.

First, a correction. A Missouri small claims judgment is not a lien on real estate. RSMo 482.365 says so in its first sentence. Guides that tell you to "record your judgment as a property lien" are describing regular civil judgments, not small claims. Your real tools:

One Missouri quirk to know before you count your money: if the debtor is the head of a family and lives in Missouri, wage garnishment drops from 25% to 10% of take-home pay. Most guides quote the flat 25% and stop. Plan around the smaller number if your debtor supports a household.

Interest helps you wait. A Missouri judgment on a contract-type claim grows at 9% per year (RSMo 408.040). Some guides quote "federal funds rate plus five." That's the rate for tort judgments, not your unpaid-invoice case. On a $5,000 judgment, 9% is $450 a year stacking on top of what they owe.

And use the clerk. RSMo 482.365 requires small claims clerks to help judgment creditors prepare collection forms. It's free help that almost nobody asks for. In Jackson County, a garnishment filing runs about $10 plus service.

When you're paid in full, file a Satisfaction of Judgment to close it out. Deeper dive: collecting your small claims judgment.

Six mistakes that sink Missouri cases

• Filing in the wrong county. Dismissed. Confirm venue under 482.330 before you pay.
• Getting the business name wrong. Sue the legal entity from the Secretary of State's records, not the sign on the door.
• Missing your own hearing. Dismissed, and in Jackson County you can't refile in small claims after a no-show.
• Never checking Case.net for service. If the defendant wasn't served, your hearing is a wasted trip.
• Ignoring the 12-case rule. File number 13 gets dismissed, and you signed a sworn statement saying you wouldn't.
• Suing someone with nothing to collect. A judgment against a broke, jobless defendant is a piece of paper. Think about collection before you file.

Frequently asked questions

What is the small claims court limit in Missouri?

$5,000, not counting interest and court costs (RSMo 482.305). If you're owed more, you can waive the extra and still use small claims, or file in the circuit court's regular division.

How much does it cost to file small claims in Missouri?

It depends on the county. St. Louis County charges $20.50, Jackson County $27.50, and Greene County $35.50. Add $10 per defendant for certified mail service, or $46 to $55 for sheriff service. Fee waivers are available if you can't pay.

What are the Missouri small claims court rules?

Money claims only, up to $5,000. No more than 12 filings per person per year, and no assigned debts (RSMo 482.330). Hearings are informal, with no jury. Either side may bring a lawyer, and either side can demand a new trial within 10 days of the judgment.

Where can I get the Missouri small claims court handbook?

The Missouri Bar publishes a free Small Claims Court Handbook. You can find it on courts.mo.gov and on many county circuit court websites, including Greene County's. It covers filing, counterclaims, and collection in plain language.

What forms do I need?

Two: the Petition for Small Claims and the Confidential Filing Information Sheet. Download both from courts.mo.gov or grab them at the circuit clerk's office. Jackson County and some other circuits add local forms, so call your clerk first.

Can I file small claims online in Missouri?

Usually not. Missouri's e-filing system is designed for attorneys, and Case.net only lets you look up cases. Plan to file in person at the circuit clerk's office. Jackson County specifically asks filers not to mail petitions.

Can I bring a lawyer to Missouri small claims court?

Yes. Missouri is one of the few states that allows attorneys in small claims for either side. You don't need one, and most people go without. A business can send an owner or a salaried employee instead of hiring counsel.

How do I appeal a Missouri small claims judgment?

File an application for trial de novo with the clerk within 10 days (RSMo 482.365). The fee varies by county, roughly $45 to $82. The case restarts from zero in front of a new judge. Collection on the original judgment continues unless the appealing side posts a bond.

How long do I have to file?

Five years for most claims, including oral contracts, property damage, and personal injury (RSMo 516.120). A written promise to pay money gets 10 years (RSMo 516.110). The clock usually starts when the harm happened.

Before you file, send one letter

Courts work. But about 70% of disputes settle after a demand letter, with no filing fee and no courtroom. Missouri judges also like seeing that you tried to fix it first. Here's how to write a demand letter, and the data on whether demand letters actually work.

PettyLawsuit sends your demand letter instantly with certified mail tracking. If they ignore it, the system keeps going: follow-up calls, emails, and a Final Notice on day 10. More than 5,000 cases handled, and most never see a courtroom. Don't let it slide.
