I live in nyc. I had a roomate that was planninng to move out in a month. The new roomate insinsited that she wanted to move in asap and asked if. I cud. Get the old 1 out sooner. The old one agreed and left. The new one came paid one mos rent and one mos security, I used half of the $ for that mos rent the other half used to return olld roomies security. (Asss I would be entitled to 30 day notice to find new roomate). I gave the keys ect. (She never brought her things). Exactly 7 days later she called and said she doesn't want the room and has a lame excuse. Next is asking for both rent and security to be returned. I say she is only enitled to the security. The next week (at night) she comes in with the keys and put some stuff in the room but still never slept there. She claims I owe for the remaining 3 weeks. When do I have to have it to her by and how much should I give?Who's legally right? Opinions?
