How to File Small Claims in Missouri: Complete Guide

To file small claims in Missouri, go to the Associate Circuit Court in the county where the defendant lives or does business. Fill out a Petition for Small Claims. Pay the filing fee ($25 to $50). Pay a service fee to notify the defendant. The court sets a hearing date, usually 30 to 60 days out. No lawyer needed.

The steps below walk you through each part. We cover the forms, service rules, and what to do in Kansas City, St. Louis, and Springfield.

Before You File: Check That Your Case Qualifies

Missouri small claims handles money disputes up to $5,000. Check these before you file:

• Your claim is $5,000 or less
• You are suing for money, not asking the court to stop someone from doing something
• You are within the statute of limitations (5 to 10 years depending on claim type)
• You know where the defendant lives or has a business address

If your claim is just over $5,000, you can cut it to $5,000 and file in small claims. Many people do this to avoid the more complex process of regular civil court.

Try a Demand Letter First

Before you file, send a formal demand letter. This is not just a nice gesture. It is often the step that gets you paid without a court date.

A demand letter states what you are owed and gives a deadline to pay. It puts the other person on notice that court comes next if they ignore it.

About 70% of disputes resolve after a demand letter. Most people do not want a judgment on their record. A certified letter with a deadline changes how seriously they take you.

You can send one through PettyLawsuit's Missouri small claims page instantly for $29. If they ignore it, you have the paper trail ready for court.

Step 1: Find the Right Court

File in the county where the defendant lives or does business. In Missouri, that is the Associate Circuit Court for that county.

If the dispute involved a product or service, you can sometimes file in the county where the transaction happened. But when in doubt, file where the defendant is located.

Filing in the wrong county is a common mistake. The case gets dismissed and you have to refile. Look up the defendant's address and confirm the county before you go.

Missouri has 114 counties plus the City of St. Louis, which is its own jurisdiction. That last part trips people up. Read the St. Louis section below carefully.

Kansas City (Jackson County and Clay County)

Kansas City spans two counties. Most of the city is in Jackson County. North Kansas City and Liberty are in Clay County.

For Jackson County, the Associate Circuit Court is at 415 East 12th Street in Kansas City. For Clay County, file at the courthouse in Liberty.

Jackson County schedules small claims on set days each week. Call the clerk before you go to confirm the current schedule. Ask if they need any local forms beyond the standard state ones.

St. Louis: City vs. County

This is the most common source of confusion in Missouri. St. Louis City and St. Louis County are two completely separate jurisdictions. They do not share a courthouse.

• St. Louis City: File at the 22nd Judicial Circuit, 10 North Tucker Boulevard in downtown St. Louis.
• St. Louis County: File at the St. Louis County courthouse in Clayton, at 105 South Central Avenue.

If your defendant lives in the city limits, go to Tucker Boulevard. If they live in suburbs like Kirkwood or Florissant, go to Clayton. Getting this wrong costs you time and fees.

Springfield (Greene County)

For Springfield and surrounding areas, file at the Greene County Circuit Court at 940 Boonville Avenue.

Greene County charges a flat $35.50 filing fee. Certified mail service is $10 per defendant. Sheriff service is $55 per defendant.

The clerk's office is helpful with basic procedure questions. They cannot give legal advice, but they will walk you through the forms.

Step 2: Fill Out the Forms

Missouri has standard small claims forms on the Missouri Courts website at courts.mo.gov. Here are the key ones:

Petition for Small Claims

This is the main document. It asks for:

• Your name and address
• The defendant's name and address
• The amount you are claiming
• A short description of the dispute
• The date the problem started

Keep the dispute description short. One or two sentences is enough. You tell the full story at the hearing.

Filing Information Sheet

Most counties also require this form. It captures case type and party type codes. The clerk uses these to categorize your case. The code lists are on the Missouri Courts website.

Counterclaims

The defendant can file a Counterclaim of Small Claims against you. This means they are suing you back at the same hearing. You may not know until you arrive. Bring documentation to defend any possible counterclaim.

Step 3: Pay the Filing Fee

Bring cash or a money order. Some counties take credit cards. Not all. Call ahead to check.

General fee ranges in Missouri:

• Claims up to $100: about $25
• Claims from $100 to $500: about $30
• Claims from $500 to $5,000: about $40 to $50

Pay the service fee at the same time. Pick certified mail ($10) or sheriff service ($55 per defendant in most counties).

Step 4: Serve the Defendant

The defendant must be officially notified about the lawsuit. This is called service of process. Without it, the case cannot go forward.

Certified Mail Service

The court mails the summons by certified mail. Cost: about $10. It is the cheapest option.

The downside: if the defendant refuses to sign or is never home, service fails. You have to try again another way.

Sheriff Service

A deputy delivers the summons in person. Cost: about $55 per defendant. It is more reliable for defendants who dodge mail.

If the defendant is in a different county than where you filed, contact that county's sheriff directly for their fee.

Confirm Service Before the Hearing

Check your case on Case.net before the hearing. Case.net is the Missouri Courts online case lookup. Search by your name or case number. It shows whether the defendant was served.

If service failed, your hearing gets postponed. You need to re-attempt service. Check a few days before the date so you are not surprised.

Step 5: Prepare for the Hearing

This step gets skipped. Do not skip it. Your hearing is one shot to make your case.

Gather Your Evidence

Bring everything that supports your claim. Organize it so you can find things fast:

• Contracts, receipts, or invoices
• Text messages and emails (print them)
• Photos of property damage
• Bank records showing payments you made
• Repair estimates from contractors
• Any demand letters you sent before filing

Know Your Dollar Amount

The judge will ask how much you are claiming and how you got there. Be ready with a clear answer. If you are claiming $2,800 for a contractor who walked off, show what you paid, what you got, and what it cost to fix.

Witnesses

You can bring witnesses. If one is reluctant to come, ask the court for a subpoena. Ask the clerk's office about the subpoena process when you file.

Step 6: The Hearing

Show up on time. If you miss the hearing, your case is dismissed.

Missouri small claims hearings are informal. No formal legal procedure. The judge controls the room and keeps things moving. Be direct. Stick to the facts.

The judge hears from both sides, reviews evidence, and asks questions. They may rule right then or send a written decision in the mail within a few days.

Step 7: After the Judgment

Winning a judgment and getting paid are two different steps.

If the defendant pays, file a Satisfaction of Judgment with the court. This closes the case.

If they do not pay, Missouri gives you tools to collect:

• Wage garnishment: The court orders the defendant's employer to withhold part of their paycheck.
• Bank levy: Freeze and seize funds from their bank account.
• Property lien: Attach the judgment to real estate they own in Missouri.

A Missouri judgment lasts 10 years and can be renewed. Even slow collection keeps your options open.

If You Lose

You can file an Application for Trial de Novo within 10 days of the ruling. This asks a circuit court to hear the case again. You will need a lawyer at that point. Only appeal if the amount justifies the cost.

Common Mistakes to Avoid

• Filing in the wrong county. The case gets dismissed. Confirm the defendant's county first.
• Bad address for the defendant. Service fails. No service, no hearing.
• Not checking if service was completed. Verify on Case.net before you go to court.
• Missing the hearing. Your case is dismissed. Set calendar reminders.
• Disorganized documents. Fumbling through papers in front of a judge hurts your credibility. Sort everything before you walk in.
• Wrong dollar amount. Know your total before you file. You cannot add to the claim after.

How Long Does the Process Take?

Filing to hearing: 30 to 60 days in most Missouri counties. Some are faster. After the hearing, the judge may rule that day or take a few days.

Total timeline from filing to judgment: about 1 to 3 months. If you have to collect after the judgment, that can take more time.
