Legal Question in Landlord & Tenant Law in Illinois

If you have rent receipts, or cancelled checks, you can prove you paid rent. Otherwise it's tough unless the landlord admits it, or you can get his records to prove it. If you are being evicted in retaliation, however, that is a defense under Illinois law especially if the house violated code - but you'd need proof of filing a complaint and any resulting action (or inaction) by the building department. However, these things can be very tricky and since you can't post all the possible relevant facts here, the information I'm providing can NOT be relied on as legal advice - get an attorney for a complete review of the situation.
