<prompt> Human: Long time lurker first time poster:Here is the situation: My roommate is breaking our IU Apartment rental contract and moving out in the middle of the year. I have a separate contract with him, which is signed by us 19 y.o. and our parents saying thatBoth parties agree that they will each be held responsible for covering the rent plus any additional incurred costs for the entire rental agreement period, as stated above. This includes the continuation of payments in the case of an early move out, regardless of the situation that caused the move out, unless otherwise agreed upon.In addition, they agreed on the same contract to pay me about 100 per month to help with my part of the bill, because I wanted to live in a cheaper apartment than what he wanted. I have received 1 check from his mom for 300.Now you are probably wondering why he is moving out. I asked him if I was bothering him and he replied No it has absolutely nothing to do with you to be honest its just I dont like the apartment that much and its far from friendsI going to put an ad on IU classifieds to try to find a new roommate. Would there be any chance that you would want to move out and go to a different apartmentSo from what I observed he is a very spoiled kid. He screams at the tv when he loses video games, his mom buys him anything he wants, he yells at his mom on the phone without consequence, and last but not least, his mom buys him alcohol. Lots of alcohol.Anyway its his life and we have been getting along really well in my opinion. Never a single disagreement or passive-aggressiveness from either him or me. My question is, what sort of deal should I strike up with them? I dont want to completely screw him over but I dont believe I should suffer because of his frivolous decisions. If it comes down to it, would it be worth it to take him to small claims court or not?Here is the specific financial info:It would cost, with Roommates 100 payment, around 2800 to live here til the end of the semesterWithout his payment it would cost around 3500If he leaves and I have to pay the full room cost it will be 7308 for the rest of the contract not happeningIf he leaves and moves me to BBHHN Apartments it will be 3717 if they have an open apartment which is unlikely, but I just emailed to find outContract breakage is 60 of the remaining costs, so with Roommates payment that would be around: 1680 for meAnd without: 2100I am thinking I will just move out, but I dont know how much if anything I should ask him to provide cost-wise.Feel free to ask for clarification and thanks for the help!TL;DR: Roommate is moving out and inadvertently screwing me over financially even though we have a personal contract making that impossible hopefully.EDIT: Thanks for all the comments! I will hold them to the contract, let them find a suitable replacement tenant, or ask them to pay to break my contract too.  <response>: I think you abide by the contract, and ask his family to pay whatever your out of pocket costs are for whatever decision you end up taking.Why have a contract if youre not going to enforce it?You take him to small claims court if you have to, but the parents are going to pay it anyway.
