The Illinois Forcible Entry and Detained Notice To Defendant is a document that is used in the state of Illinois when a landlord is evicting a tenant from a rental property. This document is also known as an eviction notice. There are three types of Illinois Forcible Entry and Detained Notice To Defendant: a 5-Day Notice to Vacate, a 10-Day Notice to Vacate, and a 30-Day Notice to Vacate. The 5-Day Notice to Vacate is issued when the tenant has not paid rent or has violated the rental agreement in some other way. The notice informs the tenant that they have five days to vacate the premises or face eviction proceedings. The 10-Day Notice to Vacate is issued when the tenant is occupying the property after the lease has expired or has breached the rental agreement in some other way. The notice informs the tenant that they have ten days to vacate the premises or face eviction proceedings. The 30-Day Notice to Vacate is issued when the tenant is a month-to-month tenant and the landlord wishes to terminate the tenancy. The notice informs the tenant that they have thirty days to vacate the premises or face eviction proceedings. The Illinois Forcible Entry and Detained Notice To Defendant is a legally binding document and must be served on the tenant in order for the eviction to proceed. Failure to comply with the terms of the notice can result in legal action being taken against the tenant, including a court order to vacate the premises.
