Chicago, Illinois - 10 years ago I signed a lease on an apartment for 1 year with a security deposit. At the end of the lease I was never asked to sign a new lease and the rent has not changed for 10 years. (During the 10 years there was never any painting/carpet cleaning/interior maintenance-other than what was asked for/nor any notice of any problems). Six months ago I let my adult son take over the apartment with an adult male room-mate and gave a note to the landlord stating that the boys would be paying the rent and that I would leave the security deposit in place for them. I also stated that if they wanted a new lease signed it would be ok (even warned the boys there may be a rent increase) and that I would await their decision. Having never heard from the landlord I presumed everything was ok. Last week a note was slipped under the door stating that the young men had till the end of the month to vacate the apartment. I guess my question is: would it be a safe assumption that the original lease automatically renewed each April for the last 10 years and what are the rights of the two young men now renting the apartment? Also, am I legally involved in this in any way?
