Landlord Sue Tenant in Missouri Small Claims Court

When the Deposit Doesn't Cover the Damage

A tenant moves out and leaves behind $3,800 in damage — holes in walls, stained carpet, a broken appliance, missing fixtures. The security deposit was $900. After applying the deposit, you're still out nearly $3,000. Missouri small claims court is the practical way to recover that difference without hiring a lawyer, as long as the amount is under $5,000.

Small claims in Missouri handles money claims only under RSMo § 482.305. As a landlord, you can sue for unpaid rent, property damage beyond the security deposit, cleaning costs above normal wear and tear, or other monetary losses. What you cannot do in small claims court is evict a current tenant — eviction proceedings go through the regular Associate Circuit Court under RSMo Chapter 535.

The Security Deposit Accounting Comes First

Before suing for damages, you must comply with Missouri's security deposit statute (RSMo § 535.300). Within 30 days after the tenancy ends and the tenant surrenders possession, you're required to either return the full deposit or send an itemized list of deductions with any remaining balance.

If a court finds that you wrongfully withheld any part of the deposit, the tenant can seek up to double the amount wrongfully withheld under § 535.300. Make sure your accounting was sent on time, itemized properly, and mailed to the tenant's last known address before you file a claim for the excess.

Calculating Your Claim

Your claim amount is the total documented damage minus the security deposit you already retained. Break it down:

• Repair costs — actual contractor invoices or estimates for wall repair, painting, carpet replacement, appliance repair or replacement. "Normal wear and tear" isn't compensable — a carpet that's worn after five years of tenancy isn't damage; a carpet with cigarette burns after six months is.
• Unpaid rent — any balance owed under the lease, including the final month if the tenant skipped.
• Cleaning costs — lease-authorized charges for cleaning beyond ordinary wear and tear, documented with receipts.
• Less the deposit retained — subtract whatever you withheld from the deposit.

If the total exceeds $5,000, you can waive the excess and file in small claims, or file in regular Associate Circuit Court for a claim up to $25,000. Claims over $25,000 belong in the general Circuit Court.

Finding the Former Tenant

The hardest part of suing a former tenant is often locating them for service. They've moved, and the forwarding address they gave (if any) might be wrong. Missouri requires the defendant to be served at least 10 days before the hearing.

Steps to locate a former tenant:

• Check the forwarding address on file from their move-out notice
• Search public records and voter registration for the county they moved to
• Ask USPS whether a forwarding address is available; use a court-authorized service method at the defendant's address.
• Check the Missouri Case.net system — if they've had other court involvement, their current address may be on file

If the certified-mail return receipt is not signed by the addressee, it does not provide the proof of service described in § 482.350. Check the docket and ask the clerk whether to request an alias summons for another authorized service method, such as sheriff service.

Evidence That Wins Landlord Cases

Judges see hundreds of security deposit and property damage cases. The landlords who win consistently are the ones with documentation. Bring three copies of:

• The lease agreement — showing the tenant's obligations for maintenance and condition upon vacating
• Move-in inspection report with photos — proving the condition of the unit at the start of tenancy. This is your baseline. Without it, the tenant can claim the damage was pre-existing.
• Move-out inspection report with photos — dated, timestamped, showing every item of damage
• Your itemized security deposit accounting — the letter you sent within 30 days, showing deductions and any balance owed
• Repair invoices or contractor estimates — itemized, from licensed contractors where possible
• Rent ledger — showing payment history and any unpaid balance
• The demand letter — sent by certified mail to the tenant's last known address

The move-in/move-out photo comparison is the single most powerful piece of evidence in a landlord case. If you don't have move-in photos, your case rests on your testimony versus the tenant's denial.

Filing the Petition

File OSCA Form SC40 at the Associate Circuit Clerk in the county where the rental property is located. Filing fees vary by county — $20.50 in St. Louis County, $27.50 in Jackson County, $35.50 in Greene County. Certified mail service is about $10; sheriff service is $46 in Jackson County, $49 in St. Charles County (including $9 mileage, effective March 1, 2026), and $55 in Greene County.

On the petition, describe the damage and unpaid amounts briefly, state the total you're claiming, and sign the statutory declaration. If the landlord is an LLC, confirm its representation requirements with Missouri counsel; RSMo § 482.310's small-claims exception expressly names corporations and unincorporated associations, not LLCs.

At the Hearing

Present your case chronologically: the lease terms, the move-in condition, the move-out condition, the damage discovered, the accounting you sent, and the unpaid balance. Hand the judge your evidence binder and walk through the key exhibits.

The tenant may argue normal wear and tear, claim the damage was pre-existing, or say your repairs were overpriced. Your move-in photos and professional repair estimates counter these arguments directly.

If the tenant has been duly served and doesn't appear, you still must present a prima facie case; the judge may enter a default judgment under RSMo § 482.355. Either party can appeal within 10 days under RSMo § 482.365 (Application for Trial de Novo).
