Me and my x boyfriend signed a lease together in January. My questions is, if he never physicaly lived there but signed the lease is he held accountable for half of the rent. Even though we never lived together he has always payed his half, but now all the sudden he doesn't and he has called the apartment manager requesting his name to be taken off of the lease, in which she has advised that it can't be done. So can I take him to court to get him to pay for his half of the rent since he co signed?
