An Illinois Complaint In Forcible Entry and Detained is a legal document that is used to initiate a court action seeking the eviction of a tenant from a rental property. This document is filed in the circuit court and is used when a landlord is seeking to evict a tenant for non-payment of rent, breach of the lease agreement, or when the tenant has remained in the property after the lease is expired. There are two types of Complaint In Forcible Entry and Detained in Illinois: Summons and Complaint and Special Complaint. The Summons and Complaint is used when the tenant has been issued a proper notice to vacate the premises and has failed to do so. The Special Complaint is used when the landlord seeks to evict a tenant without providing them with a notice to vacate the premises. In either case, the landlord must provide the tenant with a copy of the Complaint In Forcible Entry and Detained.
