Duty to mitigate, state DV early-termination protections, and the federal SCRA military exception, what a Missouri landlord can and cannot charge after a tenant breaks the lease.
If you break a lease early in Missouri, your real exposure is rarely the entire remaining balance. Under Bolling Co. v. Barrington Co., 818 S.W.2d 358 (Mo. Ct. App. 1991), Missouri follows the modern duty to mitigate: when a tenant moves out, the landlord must make reasonable efforts to re-rent the unit rather than letting it sit empty and billing you month after month. Because of that, what you typically owe is the rent lost while the unit stays reasonably vacant, plus genuine costs the landlord incurs to re-let it.
This is a court-recognized (case-law) duty, not a statute, but Missouri trial courts apply it. With average rent in the state around $854 a month, the gap between a few weeks of vacancy and a full unmitigated balance is large — which is exactly why the mitigation rule matters. Below we cover what a Missouri landlord can lawfully charge versus an unenforceable penalty, the domestic-violence exit under Mo. Rev. Stat. § 441.920, and the federal SCRA military exception.
Missouri case law recognizes the modern duty to mitigate. § 441.920 allows DV victims to terminate the lease.
The state DV statute operates in addition to, not instead of, the federal Violence Against Women Act (VAWA), which independently protects DV/SA/dating-violence/stalking victims in HUD-covered housing programs (public housing, HCV/Section 8, project-based, LIHTC, HOME, HOPWA). A Missouri tenant in covered housing has the benefit of whichever statute is more protective on the facts.
Missouri does not let a landlord simply collect the full remaining rent as if you never left. Under Bolling Co. v. Barrington Co., the landlord has a duty to mitigate damages — to take reasonable steps to re-rent the unit at a fair rate. Your liability is the rent lost during the reasonable time it takes to find a replacement tenant, reduced by any rent the landlord collects (or could have collected) from a new renter.
Practically, that means the longer a landlord sits on an empty unit without advertising or showing it, the weaker the claim against you. Keep records: your written notice, the move-out date, and any evidence the unit was re-listed or re-rented. A tenant who hands back keys and a forwarding address is in a far stronger position than one who simply disappears.
So what can a Missouri landlord actually charge? Legitimate items include the rent lost during a reasonable vacancy, advertising or re-letting costs, and any specific unpaid obligations under the lease (utilities, damage beyond normal wear). These are compensatory — they put the landlord back where they would have been, not ahead of it.
What does not survive scrutiny is a charge designed purely to punish. A clause demanding the entire remaining balance regardless of re-rental, or a flat "termination fee" untethered to actual loss, runs against the mitigation duty and can be challenged as an unenforceable penalty. If your lease has a buyout option (for example, two months' rent to walk away), read it closely — an option you choose is different from a penalty imposed after the fact. When in doubt, the mitigation rule is your backstop: damages must reflect real, reasonable loss.
Missouri gives survivors of domestic violence a statutory path out of a lease. Under Mo. Rev. Stat. § 441.920, a tenant who is a victim of domestic violence may terminate the lease early without owing the rent that would otherwise accrue after termination, provided the statute's conditions are met.
The statute typically requires written notice to the landlord and supporting documentation — such as an order of protection or other qualifying proof — so follow the precise steps in the law and keep copies of everything you submit. Because this is a dedicated statutory right, it overrides ordinary lease-break liability for the qualifying tenant: you are not at the mercy of how quickly the unit re-rents. If you are leaving an abusive situation, this provision, not the general mitigation analysis, is the route to use.
Servicemembers have a federal right that no lease and no state rule can override. Under the Servicemembers Civil Relief Act, 50 U.S.C. § 3955, a tenant who enters active duty or receives qualifying permanent-change-of-station or deployment orders may terminate a residential lease early. The tenant delivers written notice plus a copy of the orders; the lease ends a set period after the next rent due date, and the landlord cannot charge an early-termination penalty for a proper SCRA termination.
For landlords, ignoring a valid SCRA notice is the costliest mistake here — improperly withholding the exit or imposing penalties can expose you to federal liability. When a tenant presents military orders, process the termination rather than enforcing the lease term. The related federal VAWA framework (34 U.S.C. § 12491) adds protections in covered housing for survivors of domestic violence and stalking.
The most common Missouri mistake is letting an early-termination clause sit in the lease, charging it automatically, and not bothering to re-list the unit. In a duty-to-mitigate jurisdiction, that pattern is a losing posture: the tenant's lawyer asks one question, "what did you do to re-rent?", and the answer determines the case.

This page summarizes Missouri's duty-to-mitigate rule as recognized in Bolling Co. v. Barrington Co., 818 S.W.2d 358 (Mo. Ct. App. 1991), the domestic-violence early-termination statute at Mo. Rev. Stat. § 441.920, and the federal protections of the Servicemembers Civil Relief Act (50 U.S.C. § 3955) and VAWA (34 U.S.C. § 12491). Last reviewed June 2026. It is general information, not legal advice; consult a licensed Missouri attorney about your specific lease and circumstances.
Yes. Under Bolling Co. v. Barrington Co., 818 S.W.2d 358 (Mo. Ct. App. 1991), Missouri recognizes a duty to mitigate. After you move out, the landlord must make reasonable efforts to re-rent rather than let the unit sit empty and bill you the full balance. Your liability is generally limited to the rent lost during a reasonable vacancy, reduced by what a replacement tenant pays or could have paid.
Yes. The federal Servicemembers Civil Relief Act, 50 U.S.C. § 3955, lets a tenant who enters active duty or receives qualifying orders terminate a residential lease early with written notice and a copy of the orders. The lease ends a set period after the next rent due date, and the landlord cannot impose an early-termination penalty for a valid SCRA termination.
Yes. Mo. Rev. Stat. § 441.920 allows a tenant who is a victim of domestic violence to terminate the lease early without owing rent that would otherwise accrue after termination, when the statute's conditions are satisfied. Expect to provide written notice and supporting documentation such as an order of protection, and keep copies of everything you submit.
Compensatory amounts only: the rent lost during a reasonable vacancy, reasonable re-letting or advertising costs, and any specific unpaid obligations like utilities or damage beyond normal wear. A charge for the entire remaining balance regardless of re-rental, or a flat penalty untethered to actual loss, conflicts with the duty to mitigate and can be challenged as an unenforceable penalty.
