The Illinois 10-Day Notice is a legal notification required to be sent to a tenant that is in violation of their lease agreement. It is used to notify the tenant that they must either pay the rent or vacate the premises within 10 days, or risk the initiation of eviction proceedings. The notice must be in writing and must be served either by personal delivery to the tenant or by mail. There are two types of Illinois 10 Day Notice. The first type is the Non-Payment of Rent Notice, which is used if the tenant has not paid their rental obligation. The second type is the Termination of Tenancy Notice, which is used if the tenant has violated other terms of the lease agreement. Both types of notices must include a statement of the tenant’s right to contest the eviction in court; the notice must also include the amount of rent due, the location of the premises, the date the notice is served, and the signature of the landlord or their representative.
