The state of Kansas has established specific procedures for terminating a tenancy and does not recognize any others. Your planned move-out date should be specified.
Leases can vary.
Most leases will only talk about notices to move out at the end or for the renewal of the lease, since you are not expected to be giving notice and leaving in the middle of a term. If you have a lease, read it carefully for notice requirements. Rare exceptions to this rule include situations where the landlord never rented to the person in the first place or where life-threatening circumstances require that a property be vacated immediately. In Kansas, a landlord is generally not required to give a reason for an eviction. Also, retaliatory evictions are illegal whether a reason is stated or not.
