Roommate money dispute in Missouri small claims

Ex-roommate owes you money? Recover it in small claims.

When a roommate leaves without paying their share of rent, utilities, or other agreed expenses — or when money was lent and not repaid — small claims court is an accessible option to recover. Your case turns on showing what was agreed, what was paid by each person, and what remains unpaid. A written roommate agreement or lease addendum is the strongest evidence, but texts, emails, and payment records can also establish the arrangement.

In Missouri, small-claims cases are heard in the Small Claims Court (the small claims division of the Circuit Court) and you can sue for up to $5,000 (exclusive of interest and costs).

Good to know: Missouri does not have a standalone small claims court. "Small claims court" is the designation a circuit court judge takes on when hearing small claims matters; it operates as the small claims division/docket of the circuit court (RSMo 482.300). Note also the $5,000 cap is exclusive of interest and costs. The general personal-injury limitation period is 5 years under 516.120(4); a narrower 2-year period applies to specific intentional torts (assault, battery, libel, slander, false imprisonment) under 516.140.

Roommate money dispute in Missouri: local specifics

Missouri applies a significantly longer limitations period to written contracts than to oral agreements, making it very important whether your roommate arrangement was documented in writing. File your petition in the small claims division of the Circuit Court.

Roommate money dispute: steps that matter

1. Gather your roommate agreement, lease, and any written communications about shared expenses, payments made, and what was owed.
2. Compile payment records showing what you paid and what the other person did or did not pay.
3. Send a written demand for the amount owed and keep proof you sent it.
4. File in the court for the county where the rental property is located or where the defendant currently lives.

Filing your petition (statement of claim) in Missouri

1. Complete and file the small claims petition. An action is commenced by filing a petition (on a form substantially similar to the statutory petition form) with the clerk of the small claims court. Per RSMo 482.340: "An action on a small claim may be commenced by filing with the clerk of the small claims court a form substantially similar to the petition form provided in this section."
2. Sign the required plaintiff statement. At filing, the plaintiff must sign a statement that he or she is not the assignee of the claim (RSMo 482.330).
3. Pay the filing fee and cost deposit. Pay court costs and a deposit as security for costs. Per RSMo 482.345: "A person filing an action in small claims court shall pay court costs and a deposit as security for costs in amounts determined pursuant to sections 488.010 to 488.020." Exact amounts are set by those statutes/surcharges and vary by county.
4. Have the defendant served. The clerk issues a summons with the petition attached; the defendant is served, normally by certified mail, return receipt requested, restricted delivery (personal service only if the plaintiff requests it) per RSMo 482.350.
5. Appear for trial on the date set in the summons. The defendant must appear at the time and place specified in the summons, and the case is tried on the day set for appearance unless continued by the court (RSMo 482.355).

Filing fees: Court costs and a cost deposit are set under RSMo 488.010 to 488.020 and vary by county; confirm the amount with the clerk.

Deadline that applies to your roommate money dispute

A roommate money dispute is usually a contract or debt claim — unpaid shared expenses, a loan between roommates, or one roommate leaving the other holding the lease. The statute of limitations is typically the contract or debt period, starting from when the money was due or the last payment was made.

Written contract: 10 years (RSMo § 516.110)

Answering a lawsuit: No written answer is required. The defendant must appear at the time and place specified in the summons, and the case is tried on the day set for appearance. Service must show delivery at least ten days before the appearance date.

Serving the defendant: Service is normally by certified mail, return receipt requested, restricted delivery to the addressee; personal service is not required unless the plaintiff specifically requests it. The return receipt must show delivery at least ten days before the appearance date to constitute proof of service.

Appeals: A party aggrieved by a final small claims judgment (except a consent judgment) may obtain a trial de novo by filing an application for trial de novo with the clerk within 10 days after the judgment is rendered.
