Dear [________________________________]:

This law firm represents [________________________________] ("Tenant" or "Client") regarding your failure to comply with Missouri's security deposit statute, RSMo § 535.300, following our Client's vacatur of the above-referenced premises. This letter constitutes formal demand under Missouri law for return of the security deposit, applicable statutory damages, and attorney's fees.

I. MISSOURI LEGAL FRAMEWORK — RSMo § 535.300

A. Missouri's Strict 30-Day Deadline

Missouri's security deposit statute is among the most specific in the country. Under RSMo § 535.300(3), within thirty (30) days after termination of the tenancy and delivery of possession by the tenant, the landlord must either:

1. Return the full security deposit to the tenant; OR
2. Return the balance of the deposit together with a written, itemized statement of all deductions.

The 30-day clock begins running when both conditions are met: (a) termination of the tenancy, and (b) delivery of possession. Providing a forwarding address satisfies delivery of possession in most circumstances. Missouri courts apply this deadline strictly — there is no grace period.

B. Missouri's Deposit Cap — Two Months' Rent

Under RSMo § 535.300(1), a landlord may not collect a security deposit exceeding two months' rent. Missouri does not require the deposit to be held in a separate account, and Missouri does not require payment of interest on security deposits — unlike several other states.

C. Written Itemization Is Mandatory

The itemized statement under RSMo § 535.300(3) must:

• Identify each specific deduction claimed
• State the dollar amount for each deduction
• Accompany the return of any remaining balance

A generic statement such as "cleaning and repairs" is insufficient. If the landlord fails to provide an adequate itemization within 30 days, the entire deposit becomes recoverable as wrongfully withheld.

D. Permissible vs. Impermissible Deductions — RSMo § 535.300(5)

Missouri law permits deductions only for:

• Unpaid rent
• Damages to the premises beyond normal wear and tear
• Other amounts due and owing under the lease

Missouri law prohibits deductions for:

• Normal wear and tear — the inevitable deterioration resulting from ordinary use of the premises
• Pre-existing conditions present before Tenant's occupancy
• Conditions arising from the landlord's failure to maintain the premises under RSMo § 535.160
• Routine cleaning between tenancies that is part of normal landlord turnover

E. Statutory Damages — Up to Twice the Amount Wrongfully Withheld

RSMo § 535.300(6) is Missouri's penalty provision. If a landlord wrongfully withholds all or any portion of the security deposit in violation of this section, the tenant may recover as damages twice the amount wrongfully withheld, plus reasonable attorney's fees.

Missouri courts have held that the "twice the amount wrongfully withheld" remedy is mandatory once wrongful withholding is established — it is not discretionary.

II. FACTUAL BACKGROUND

A. Tenancy Information

B. Move-Out and Possession Delivery

Notice to Vacate:

Delivery of Possession:

Statutory 30-Day Deadline Calculation:

C. Condition of Premises at Move-Out

Our Client left the premises in the following condition:

☐ Professionally cleaned — our Client hired [________________________________] to professionally clean the premises on [__/__/____]

☐ All personal property removed by [__/__/____]

☐ No damage beyond normal wear and tear — any changes were the result of ordinary, expected use during the tenancy

☐ Photographic documentation — our Client has time-stamped photographs of the premises at both move-in and move-out

☐ Video walkthrough conducted at move-out on [__/__/____]

III. LANDLORD'S VIOLATIONS OF RSMo § 535.300

You have violated Missouri's security deposit statute in the following respects:

☐ Failure to Return Deposit Within 30 Days (RSMo § 535.300(3)): The 30-day statutory deadline elapsed on [__/__/____]. As of the date of this letter, you have not returned any portion of the deposit. This is a per se violation triggering double damages.

☐ Failure to Provide Written Itemization Within 30 Days (RSMo § 535.300(3)): You have not provided a written itemized statement of deductions within the 30-day period. Without a proper itemization, no deductions are permissible.

☐ Deficient Itemization: You provided a purported itemization on [__/__/____], but it is legally deficient because: [________________________________]

☐ Improper Deductions — Normal Wear and Tear: You have deducted for items that constitute normal wear and tear under Missouri law, which are not permissible deductions. These include:
☐ Minor scuff marks and nail holes from ordinary use
☐ Carpet wear in traffic areas from normal foot traffic
☐ Faded or slightly dingy paint from ordinary occupancy
☐ Worn fixtures, handles, or locks from normal use
☐ Other: [________________________________]

☐ Excessive Deposit Collected (RSMo § 535.300(1)): You collected a deposit of $[____] which exceeds the two-month cap of $[____].

☐ Deductions for Pre-Existing Conditions: You have charged for conditions that existed prior to our Client's tenancy and are documented in the move-in inspection report.

☐ Bad Faith Retention: You have retained the deposit in bad faith, as evidenced by: [________________________________]

IV. NORMAL WEAR AND TEAR UNDER MISSOURI LAW

Missouri courts define "normal wear and tear" as the expected and inevitable deterioration of property resulting from ordinary use. Missouri landlords may not deduct for:

Missouri distinguishes between ordinary deterioration (landlord's cost of business) and affirmative damage caused by tenant negligence or abuse (deductible). Any ambiguity under Missouri law is typically construed in the tenant's favor.

V. DAMAGES AND REMEDIES

A. Deposit Amount Owed

B. Statutory Double Damages — RSMo § 535.300(6)

Missouri's penalty provision is automatic upon proof of wrongful withholding. The tenant is entitled to twice the amount wrongfully withheld:

C. Attorney's Fees — RSMo § 535.300(6)

Missouri law expressly awards reasonable attorney's fees to a prevailing tenant in a wrongful withholding action. Attorney's fees incurred to date: $[____________________]

D. Total Demand

VI. EVIDENCE IN OUR POSSESSION

☐ Original lease agreement and all addenda

☐ Move-in inspection report/checklist signed by landlord

VIII. CONSEQUENCES OF NON-COMPLIANCE

If you fail to comply with this demand within fourteen (14) days, we are authorized and prepared to:

1. File Suit in Missouri Circuit Court: For claims at or below $5,000 (including double damages and fees), we will file in the Small Claims Division of the Missouri Circuit Court (RSMo § 482.300), where no attorney appearance is required. For larger amounts, we will file in the Associate Division or Circuit Division of the Missouri Circuit Court.

2. Seek Mandatory Double Damages: Request that the court award twice the amount wrongfully withheld under RSMo § 535.300(6). Missouri courts treat this as a mandatory remedy upon proof of wrongful withholding.

3. Seek Attorney's Fees: Request the court award all reasonable attorney's fees and costs under RSMo § 535.300(6).

4. Report to Missouri Attorney General: File a complaint with the Missouri Attorney General's Consumer Protection Division at (573) 751-3321.

5. Report to Local Housing Authority: Notify the applicable local housing authority and any relevant licensing bodies.

6. Enforce Judgment: Upon obtaining judgment, pursue all Missouri collection remedies including wage garnishment under RSMo § 525.030, bank account levies, and judgment liens on real property.

Please respond in writing within fourteen (14) days. Your written response should include:

MISSOURI SECURITY DEPOSIT — LEGAL REQUIREMENTS QUICK REFERENCE

MISSOURI-SPECIFIC LEGAL NOTES

☐ Strict 30-Day Deadline — No Grace Period: Missouri courts enforce the 30-day deadline strictly. A landlord who sends the itemization on day 31 may lose the right to retain any portion of the deposit. Document the date of termination and the date possession was delivered separately.

☐ Possession vs. Termination: The 30-day clock does not start until both termination of tenancy and delivery of possession occur. A tenant's written notice with a clear move-out date and key return establishes both events. Encourage clients to provide forwarding addresses in writing on or before the move-out date.

☐ Double Damages Are Mandatory: Unlike some states where penalty damages are discretionary, Missouri's RSMo § 535.300(6) language — "shall recover as damages twice the amount wrongfully withheld" — has been interpreted by Missouri courts as mandatory once wrongful withholding is proven.

☐ No Kansas City or St. Louis Overlay Required: Missouri does not have state-mandated local deposit rules, but Kansas City and St. Louis City/County may have additional tenant protection ordinances. Verify applicable local code before filing.

☐ Small Claims Is Tenant-Friendly: Missouri Small Claims Court (RSMo § 482.300) is capped at $5,000 and is procedurally simple. For most residential security deposit claims, small claims is the fastest and most cost-effective forum. For claims exceeding $5,000 after double damages and fees, file in Associate Circuit Court.

☐ No Requirement for AG Arbitration: Unlike some consumer protection claims in Missouri, RSMo § 535.300 does not require pre-suit arbitration or administrative exhaustion. The tenant may file suit directly.

☐ Forwarding Address Best Practices: Recommend tenants provide forwarding addresses in writing — certified mail or email with read receipt. This eliminates any landlord defense that the deposit could not be returned because no forwarding address was provided.
