He left abruptly (without 30 days notice), leaving me to find a new roommate. The new roommate put down her deposit replacing his, which I would like to use to fix the damages that he created and reimburse unpaid bills. I have already spoken to my landlord and she said it is between the two of us since there is a full deposit down for the apartment as required. I went over the laws and it says the deposit can be used to reimburse unpaid bills and fix damages. I just want to make sure all I need to win the small claims case is my invoices from the bills he didn't pay and costs of repairs. I don't want to waste my time fighting this if he's going to win the case after destroying my apartment and leaving me to pay for everything.
