I told my landlord that I will only be living in the apartment for half a school year because of my early graduation. I told him that my girlfriend would be taking over the other half of the school year, and he was onboard with that. The contract states that she will take over my contractual obligations at some point during the term of the contract. All three housemates including myself signed the contract. However, my girlfriend never signed the lease. Her name is listed but there is no signature. She decided to transfer schools and will not be living in the apartment.
The landlord is now saying that I am legally obligated to pay for the rest of the lease, and she is off the hook since she did not sign. He said he will be taking me to court to have the judge decide. Am I legally obligated to come up with the rest of the payments?
