Debt collection defense in Missouri small claims

Being sued over an alleged debt? Organize your defense.

If a creditor, debt buyer, or collector has sued you in small claims over an alleged debt, you can respond and defend yourself. Common defenses include the debt being past the statute of limitations, the amount being wrong, the plaintiff not proving they own the debt, or the debt not being yours at all. You do not have to face it disorganized.

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).

Debt collection defense: steps that matter

  1. Read the lawsuit carefully and note your deadline to answer — missing it can cause a default judgment against you.
  2. Ask the plaintiff (in writing, through the court process) to prove the debt: the original signed agreement, a full account history, and a clear chain showing they own the debt.
  3. Check the age of the debt against the statute of limitations below; a time-barred debt is a defense you can raise.
  4. Gather your own records — payments, disputes, and any prior correspondence — and keep them together with the court dates.

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 debt collection defense

A debt claim usually rests on a contract or account, so the statute of limitations for that kind of debt is the deadline the other side has to sue you. If the debt is older than this window, the limitations period can be a defense you raise.

Oral contract or debt: 5 years (RSMo § 516.120)

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.
