Illinois Eviction Procedures and Landlord or Plaintiff Responsibilities vary depending on the type of eviction and the county in which the property is located. Generally, however, all landlords or plaintiffs must provide notice to the tenant before filing a complaint for eviction. The type of notice required varies depending on the reason for eviction, and may include a 5-Day Notice to Pay Rent or Quit, a 10-Day Notice to Vacate, or a 30-Day Notice to Terminate Tenancy. Once the notice has been served, landlords or plaintiffs may file a complaint with the Clerk of the Circuit Court in the county where the property is located. The complaint must include all relevant details, including the date of the notice, the amount of rent due, and any other fees or charges. After the complaint has been filed, landlords or plaintiffs must have a written summons delivered to the tenant. This summons must include the date and time of the court hearing and the landlord or plaintiff's name and address. At the hearing, the landlord or plaintiff must prove that the tenant is in violation of the lease agreement and that the tenant failed to comply with the notice. If the landlord or plaintiff prevails, the court will enter a judgment for possession and the tenant will have a certain time period to vacate the premises. If the tenant fails to vacate the premises, the landlord or plaintiff must hire a sheriff to serve a notice to vacate and a writ of possession. The sheriff will then physically remove the tenant and their belongings from the premises.
