The law

Mo. Rev. Stat. § 535.300. Read the statute.

Checked against the statute in October 2026. Laws change, so confirm the current rule before you rely on it.

What to do next

If the deadline has passed, or the landlord kept money without a proper list, put your request in writing. Ask for the deposit back by a specific date, and keep a copy. The free first letter in the Deposit Demand Letters kit does this for Missouri, and the deadline calculator works out your exact date from your move-out day.
