Tenant's Right to Break a Rental Lease in Missouri

Learn when and how tenants may legally break a lease in Missouri and how to limit liability for rent through the end of the lease term.

By , Attorney

Many tenants who sign a lease for their apartment or rental unit plan to stay for the full amount of time required in the lease, such as one year. But despite your best intentions, you may want (or need) to leave before your lease is up—for example, if you're a student at Missouri State and only want to stay in your apartment for the period of time that school is in session. Or perhaps you're moving in with your boyfriend or girlfriend. Sometimes, you may need to move in order to be closer to your new job or an elderly parent who needs your help.

Leaving before a fixed-term lease expires without paying the remainder of the rent due under the lease is called breaking the lease. Here's a brief review of tenant rights in Missouri to break a lease without further liability for the rent.

Tenant Rights and Responsibilities When Signing a Lease in Missouri

A lease obligates both you and your landlord for a set period of time, usually a year. Under a typical lease, a landlord can't raise the rent or change other terms, until the lease runs out (unless the lease itself provides for a change, such as a rent increase mid-lease). A landlord can't force you to move out before the lease ends, unless you fail to pay the rent or violate another significant term, such as repeatedly throwing large and noisy parties. In these cases, landlords in Missouri must follow specific procedures to end the tenancy. For example, your landlord must give you a demand to pay the rent or leave (Missouri Rev. Stat. § § 535.020, 535.060) before filing an eviction lawsuit. If you have used the premises for the sale or distribution of controlled substances, your landlord may give you an unconditional quit notice, giving you 10 days to move out. (Mo. Ann. Stat. § § 441.030, 441.040).

Tenants are legally bound to pay rent for the full lease term, typically one year, whether or not you continue to live in the rental unit—with some exceptions, as follows.

When Breaking a Lease Is Justified in Missouri

There are some important exceptions to the blanket rule that a tenant who breaks a lease owes the rent for the entire lease term. You may be able to legally move out before the lease term ends in the following situations.

You Are Starting Active Military Duty

If you enter active military service after signing a lease, you have a right to break the lease under federal law. (War and National Defense Servicemembers Civil Relief Act, 50 App. U.S.C.A. § § 501 and following.) You must be part of the "uniformed services," which includes the armed forces, commissioned corps of the national Oceanic and Atmospheric Administration (NOAA), commissioned corps of the Public Health Service, and the activated National Guard. You must give your landlord written notice of your intent to terminate your tenancy for military reasons. Once the notice is mailed or delivered, your tenancy will terminate 30 days after the date that rent is next due, even if that date is several months before your lease expires. State rules may also affect rights of tenants to break a lease in order to serve in the military.

The Rental Unit Is Unsafe or Violates Missouri Health or Safety Codes

If your landlord does not provide habitable housing under local and state housing codes, a court would probably conclude that you have been "constructively evicted;" this means that the landlord, by supplying unlivable housing, has for all practical purposes "evicted" you, so you have no further responsibility for the rent. Missouri law (Mo. Ann. Stat. § § 441.570, 441.580) sets specific requirements for the procedures you must follow before moving out because of a major repair problem. The problem must be truly serious, such as the lack of heat or other essential service.

Your Landlord Harasses You or Violates Your Privacy Rights

Missouri does not have a state law that specifies the amount of notice your landlord must give you to enter rental property. If your landlord repeatedly violates your rights to privacy, or does things like removing windows or doors, turning off your utilities, or changing the locks, you would be considered "constructively evicted," as described above; this would usually justify you breaking the lease without further rent obligation.

Landlord's Duty to Find a New Tenant in Missouri

If you don't have a legal justification to break your lease, you'll still be responsible for the balance of the rent due under the lease term. However, if you have given the landlord a security deposit (under Missouri law, not to exceed two months' rent), and if the landlord uses the deposit to cover some or all of that future rent, the landlord needs to take steps to try to find a replacement tenant. In legalese, the landlord must "mitigate damages," or lessen your responsibility for the balance of the rent. As soon as a new tenant begins paying rent, your responsibility ends. (Mo. Rev. Stat. § 535.300).

In theory, a landlord who decides not to use the security deposit can decide to return the deposit and sue the departed tenant for the entire rent due under the lease, without taking steps to find a replacement tenant for the balance of the term. But in practice, few landlords will return a pile of money, leave a unit vacant, and file a lawsuit at the end of the lease term, hoping to find the original tenant and hoping that the tenant has the funds to pay a judgment. Most landlords will use the deposit and take steps to re-rent, mindful of the danger of keeping a unit vacant and of the hassle and risk of future lawsuits.

Your landlord must look for a replacement tenant reasonably quickly, but does not need to relax standards—to re-rent below fair market value or to tenants with poor credit, for example. Your landlord can also recover legitimate expenses like advertising costs. But beyond forfeiting your deposit, you'll be responsible only for the (hopefully brief) period the unit sits vacant. The bad news is that if the landlord can't find an acceptable tenant, you will be liable for paying rent for the remainder of your lease term.

If you didn't pay a deposit or your deposit is insufficient to cover damages you caused or past-due rent, your landlord can wait until your lease ends and sue you for the total amount of lost rent. This could be a substantial amount depending on the length of your lease. Your landlord may sue you in small claims court where the limit is $5,000. Because most landlords typically require security deposits and use deposits to cover future unpaid rent, your landlord will likely choose to mitigate.

How to Minimize Your Financial Responsibility When Breaking a Lease

If you want to leave early, and you don't have legal justification to do so, there are better options than just moving out and hoping your landlord gets a new tenant quickly. There's a lot you can do to limit the amount of money you need to pay your landlord—and help ensure a good reference from the landlord when you're looking for your next place to live.

You can help the situation a lot by providing as much notice as possible and writing a sincere letter to your landlord explaining why you need to leave early. Ideally you can offer your landlord a qualified replacement tenant, someone with good credit and excellent references, to sign a new lease with your landlord.
