An Illinois 5-day notice to quit for non-payment is an eviction notice used by a landlord to inform a tenant that they have failed to paid rent on time in accordance with their lease agreement. By law, the tenant must be given five (5) days (from the date of service of the notice to quit) to pay the landlord in full before their tenancy is terminated. If the tenant does not make the full rent payment within the five-day notice, the tenancy will terminate and an eviction suit can be filed by the landlord.
