Well the answer is this. If you are evicted he must then file in court for the unpaid rent in which you were evicted for, but he also must take out your security deposit. if he trys to file for future rent at that time the judge will not allow it. but doesn;t mean your off the hook. You are obligated to pay rent on an apartment until it is rented. but the landlord can not just let it sit vacant.
i wouldn;t pay, because nine times out of ten he isn;t going to file on you twice. and most cases they don;t when, because judge doen;t understand how an apartment can stay vacant for that long. he will pull all your chains to get it, they try an scare you into it. but you don;t have to pay unless he files and the judge says OK
