Illinois. We have been renting to a tenant for approximately 2 1/2 yrs. We have been pretty flexible for her paying rent a few days past the signed contract agreement of the 1st of the month. Now the tenant has not paid rent for 2 months and will not return phone calls and we have contacted her via mail with notices for PAST DUE payments. Our signed contract is valid for one year and does not expire until January 2009. When can we serve her with a notice of eviction or is there some other step that we sould do first. ThanksWhat is the name of your state (only U.S. law)?
