Operative Text
Effect of Unsigned Lease. If the tenant shall fail to sign a written lease which has been signed and tendered to him by the owner and shall further provide the owner with a rejection in writing of such offer, the tenant's continuation of possession and payment of rent without reservation shall constitute an acceptance of the lease with the same effect as if it had been signed by the tenant.
Under 765 Ill. Comp. Stat. 745, a written lease signed and presented by a landlord does not necessarily require the tenant's physical signature to become binding. If a tenant declines to sign but also fails to provide a written rejection, and instead continues to occupy the unit and pay rent without reservation, that conduct is treated as acceptance of the lease terms — carrying the same legal weight as a signed agreement. The provision essentially closes a gap where a tenant might remain in possession under unsigned lease terms while disputing whether those terms apply.
Plain English — not legal advice.
Under 765 Ill. Comp. Stat. 745, operators who present a signed written lease to a tenant and receive no written rejection should be aware that a tenant's continued occupancy and unqualified rent payments can constitute acceptance of that lease. Compliant practice generally involves documenting when a lease was tendered, tracking whether a written rejection was received, and retaining records of rent payments and their timing. Keeping clear paper trails around lease delivery and any written communications from the tenant helps establish the status of the tenancy under this provision.

765 Ill. Comp. Stat. 745 means that if a landlord presents you with a signed lease and you continue living in the unit and paying rent without formally rejecting the offer in writing, those actions may be treated as your acceptance of all the lease's terms. Tenants who have concerns about unsigned lease terms should understand that staying and paying without reservation can have legal consequences under this provision. Tenant-rights organizations in Illinois can help explain what options exist when a tenant wants to dispute lease terms they have not formally signed.
