Terminating lease with roommate
Okay I had to move out of my apartment due to job loss. I agreed however with my roommate to pay the rent till the end of the lease. Which was jan 14. I moved out on nov 15 going to the office with roommate and my mother explaining I was leaving. But would continue paying the rent till the lease was up on jan 14. A leasing agent there said all I need is your forwarding address which we gave him and the check, with no paperwork. We then left, about two weeks later they called and said they couldn't keep my check, which was fine we paid on-line. Then like a month before the lease was up, they said I needed to sign papers which I did and have them notarized and sent back. Explaining I was vacating the apartment on jan 14. However my room mate has not found a place to live and they rented out the apartment to someone else. Now she is staying and hasn't signed anything. I called the office again and they told me I had no obligations after the 14 of January. Now she is calling me saying I have to pay ones months rent because she hasn't signed me off the lease, and she has nowhere. Is this legal? Do I have to pay that rent?
