My son is going into his third year His second year house share is breaking up as the others are having a year abroad. He's been offered a place in another flatshare, replacing one person. He asked whether it will be a new contract, or whether he will be subletting. They said it would be the same contract, but the landlord is usually happy to swap one name for another, subject to references via the agency. They also said he needs to pay the deposit to the departing tenant. This makes me a little nervous in case he will be inheriting liability for any damage caused by the previous tenant. Does the process sound legitimate?
