How long does a Missouri landlord have?
Under Mo. Rev. Stat. § 535.300, a Missouri landlord has 30 days after your tenancy ends to return your deposit or provide an itemized statement of any deductions. Missouri requires that itemized statement when the landlord keeps any part of the deposit. Count from the day the tenancy ended. If the deadline has passed and you haven’t been paid or itemized, your landlord is late — and that’s the leverage your demand letter is built on.
What penalty can a Missouri landlord face?
A landlord who keeps a deposit in bad faith may owe up to 2× the deposit. Specifically, under Mo. Rev. Stat. § 535.300, Missouri law lets a tenant seek up to twice the amount wrongfully withheld if a court finds the landlord acted in bad faith.
Important: any penalty is something a court may award if it finds the landlord acted in bad faith — it is never automatic, and you would still need to make that case. Attorney's fees are not separately recoverable under this statute.
How to get your deposit back in Missouri
- 1. Send a written demand. Put the deadline your landlord missed and the statute (Mo. Rev. Stat. § 535.300) in writing, by certified mail with return receipt, so you have proof of the date they received it.
- 2. Keep your records. Move-out photos, the walkthrough checklist, your lease, and proof you gave a forwarding address are your evidence if the landlord disputes the claim.
- 3. If they don’t pay, file in small claims. You can ask a Missouri small claims court to order the deposit returned, and — under Mo. Rev. Stat. § 535.300 — to seek up to twice the amount wrongfully withheld if a court finds the landlord acted in bad faith, which the court may award if you prove your case. The small-claims dollar limit varies by court within the state, so check your county’s limit before filing.
