My landlord wants to keep half of my security deposit. I told him I might be moving out two weeks early but I didn't and he told me I had to be out by the 18th of October because he had people moving in on the 19th. I paid him for the whole month of October. I left the place spotless taking 40 pictures to prove it is clean. The lease says that I was to give 60 days notice but I only gave him 5 weeks. Can I sue for the rest in small claims court? If he gives me a check for half can I cash it?
