Tenants gave notice that they plan to vacate. Lease Agreement stipulates they must provide 45 day written notice, however it was less than 30 days. Lease Agreement also stipulates that Landlord can show property to prospective new tenants during this time frame, however tenants are refusing to allow any showing and advised that they called the Sheriff and was told that it is illegal for LandLord to show property while tenant still occupies the property. Unless the law has changed recently, I am not aware of this. Location - Madison County, Illinois. Does anyone have any insight?
