Security deposit dispute in Missouri small claims

Landlord kept your deposit? Take it to small claims.

If your landlord did not return your security deposit, or kept part of it without a proper itemized reason, small claims court is the usual place to get it back. Most states require the landlord to return the deposit (or send an itemized list of deductions) within a set number of days after you move out. Because that specific deadline varies by state and is not a filing statute of limitations, verify it with your court or state housing agency before you rely on it.

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).

Security deposit dispute: steps that matter

  1. Document the unit's condition at move-out (photos, video, a signed walkthrough) and keep your lease and move-in records.
  2. Send the landlord a written demand for the deposit, with your forwarding address, and keep proof you sent it.
  3. Check your state's deposit-return rules (how many days the landlord had, and whether an itemized statement was required) with your court or state housing agency.
  4. If the deposit is not returned, file in small claims within the deadline below and bring your lease, photos, and demand letter.

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 security deposit dispute

A security-deposit claim is generally treated as a contract claim (your lease), so the contract statute of limitations below is the usual outer deadline to sue. Many states ALSO set a separate, shorter deadline for the landlord to return or itemize the deposit — that landlord deadline is set by your state's landlord-tenant statute, not shown here, so confirm it with your court or state consumer/housing agency.

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.
