October 31 Farm Lease Deadline for Sangamon and Menard
The Statute — What Illinois Law Actually Requires
The Illinois Farm Tenancy Act — 735 ILCS 5/9-206 — establishes the notice requirement for terminating a year-to-year agricultural tenancy. The statute requires that either the landlord or the tenant give written notice of termination at least four months before the end of the current lease year. For the overwhelming majority of central Illinois farm leases, the lease year ends March 1. Four months before March 1 is October 31. That is the deadline.
What the statute means in practice: a landlord who wants a different tenant on their Sangamon or Menard County ground starting with the 2027 crop year must serve written notice of lease termination on the current tenant by October 31, 2026. A landlord who wants to change the cash rent for 2027 — which often requires serving notice and renegotiating rather than simply announcing a new figure — may also need to have served that notice before October 31, depending on how their lease is structured and whether it has automatic renewal language. A landlord who misses the deadline does not have the option to terminate the tenancy until the following year. The tenancy renews automatically for another full year, on the current terms, and the next earliest termination date becomes October 31, 2027.
Who This Applies to and Who It Does Not
The four-month notice requirement applies to year-to-year oral and written farm tenancies governed by Illinois law. A landlord with a written lease that contains its own specific notice and termination provisions — dates, methods, form of notice — is governed by those lease terms, not the statute, if the lease is more specific than the statutory default. The statute is the floor; the lease governs if it is more specific.
A landlord who has a written lease with an explicit renewal and termination section needs to read that section before assuming the October 31 statutory deadline applies. Some well-drafted farm leases require notice by September 1, some by October 1, and some use the four-month statutory standard. If the written lease is silent on notice, the statute fills the gap. If the tenancy is oral — no written lease at all, which is more common than landlords typically acknowledge — the statute applies directly.
The deadline applies equally to a tenant who wants to leave. A tenant who has found a better opportunity, is retiring from farming, or has decided the current cash rent is not sustainable and wants out for the 2027 season must also serve notice on the landlord by October 31. Both parties have the same deadline.
What a Proper Written Notice Looks Like
The statute requires written notice. A phone call does not qualify. A text message does not qualify. A conversation at the grain elevator does not qualify. A signed letter, delivered in a way that creates documentation of receipt, is the standard that holds up if the termination is later disputed.
The notice letter does not need to be elaborate. It needs to include: the identity of the parties (landlord and tenant), the description of the property (the farm, by legal description or commonly known reference sufficient to identify it without ambiguity), the effective date of termination, and language that clearly states the tenancy is being terminated. Signed by the landlord and dated. Delivered by certified mail with return receipt requested — which creates a dated delivery record — or by personal service with a witness, or through an attorney on the landlord's behalf.
A landlord who is uncertain whether their existing lease language governs or whether the statutory default applies should have an Illinois agricultural attorney review the lease before November 1. The cost of that review is modest. The cost of missing the deadline is another full crop year on a tenancy the landlord wanted to exit, at terms they wanted to change.
The Most Common Situations Where the Deadline Matters Right Now
A landlord who inherited farmland and has been living with the prior owner's tenant for several years without reviewing the arrangement is the most frequent situation where the October 31 deadline catches someone off guard. The inherited tenant may be paying below-market rent on an oral tenancy that has been rolling year to year. The landlord has been meaning to address it. Now is the moment to address it — because if the addressing requires serving notice, the window closes in one month.
A landlord who wants to change from cash rent to a flex lease, or from one tenant to another, is in the same position. The new arrangement cannot take effect January 1 or March 1 of 2027 unless the current tenancy has been properly terminated with notice by October 31. A landlord who serves notice, then negotiates a new lease with the same tenant on updated terms, has used the notice period correctly — the tenant knows the current arrangement is ending and both parties are motivated to reach an agreement on the new terms before the old lease year ends.
An heir who has recently acquired farmland through an estate settlement and discovers the ground is under an oral tenancy with a neighbor farmer needs to move immediately. The estate settlement may have closed only recently, but the October 31 deadline exists independently of when the title transferred. If the new owner wants to change the tenant or the rent for 2027, notice is due October 31 regardless of how recently they came into ownership.
What to Do Before October 31 If You Are a Landlord
Pull your farm lease — or confirm with your tenant that one exists in writing. If there is no written lease, assume the statutory four-month notice requirement applies. Read the notice and termination provisions if you have a written lease. Decide whether you want to change the tenant, change the rent, or change the lease structure for 2027. If any of those changes require serving notice, draft the notice letter this week, sign it, and send it by certified mail before October 31 with the return receipt green card as your documentation of delivery.
If you are uncertain whether your situation requires notice, call an Illinois agricultural attorney this week. One phone call and a short letter are all that stand between a landlord who has options for 2027 and a landlord who is locked into 2026 terms for another full year because November 1 arrived before they acted.
