My roommate told me on May 1, 2012 that she will be moving out and vacating the premises on July 1, 2012 due to an unexpected pregnancy. She is on the lease until Dec 1, 2012. She believes that between May 1- July 1, that will give me enough time to find a replacement to take over the remainder of the lease. However, she is leaving this up to me to take care with minimal help. She has given her word that she will be out and pay for any utilities and rent fees until July 1 and that is it. I have written documentation that she is responsible for any rental fees until December 2012. Shouldn't this written agreement trump any verbal agreement?
