How this works in Illinois

Illinois uses a written demand for rent that gives the tenant at least 5 days after service to pay. If you want to be able to take partial payments without restarting the notice, the notice has to prominently include the statute's exact "FULL PAYMENT" sentence.

Step by step in Illinois

  1. Any time after rent is due, write a demand for the rent owed.
  2. Give a deadline that is not less than 5 days after the notice is served.
  3. Prominently include this sentence word for word: "Only FULL PAYMENT of the rent demanded in this notice will waive the landlord's right to terminate the lease under this notice, unless the landlord agrees in writing to continue the lease in exchange for receiving partial payment."
  4. If the tenant doesn't pay in full by the deadline, you can treat the lease as ended and file without any further notice or demand.
  5. You can add the claim for rent to the eviction complaint.
