Legal Question in Landlord & Tenant Law in Kansas

Without reading your lease, it is impossible to predict its strength in court. Generally, one can contract to pay rent for so many months for the ability to live in a certain location. A landlord cannot force atenant to live there. But, moving out does not usually relieve a tenant from their obligation for the rest of the rent payments.

If your posting was referring to a clause in your agreement, (wherein you say you can make all the future rental payments due now because the tenant moved out), Courts take a dim view of such clauses. If they fail to pay rent, or sent you the keys with a letter saying they are vacating and relinquishing the premises, you should evict or sue as soon as possible. Unless they can prove that the residence is now inhabitable, or some reason why they shouldn't owe the rent, you might get judgment for the past due and remainder rent on the lease agreement. Without seeing your lease agreement and any other relevant documents, no attorney can tell you what your legal stance is, nor what options you might have.

Good luck
