My lease officially ends August 31st and I am leaving the apartment complex due to unsafe conditions and terrible management. I spoke with the office a few weeks ago telling them I was leaving at the end of the lease. On Sunday, I received a phone call from the office asking when I was coming in to sign a new lease. I went to explain again that I was leaving and was told I could not because I did not sign the official notice of vacation paperwork and that I am liable for rent 30 days from when I officially sign it. They claimed they are not required to tell me about this paperwork and refused to provide a copy that I could take and review before signing it. I was forced to sign it right there "promising" to pay the additional 2 weeks' rent. Is this legal? What do I do?
