I sublet my bedroom in my apartment that I shared with one other girl. On June 1, I had an appointment with my apartment manager for the subtenant & I to sign the sublease. He was an hour late, and when he did arrive, all he did was cross out my name & SSN on the original lease and have the subtenant sign his name and write in his SSN. He also did not give me a copy of the sublease, and I forgot to ask. He keeps saying he will fax it to me, but he hasn't yet.
Yesterday, June 15, I received a call from the owner of the apartment building saying that my roommate had kicked my subtenant out on the first night, so they needed ME to pay June rent. I got them to agree to only half rent, since they waited 2 weeks before telling me about this.
My question is, did she have the right to evict him? And since my name was crossed off the lease, am I still required to continue paying rent? I live in Milwaukee, Wisconsin. The guy is a grad student at Harvard and the most polite person I've ever met, so I can't imagine he had a) violated the terms of the lease, or b) threatened physical violence upon her.
An very vague excerpt from my original lease states, "If Landlord consents to an assignment or sublease, such consent shall in no way relieve Tenant of Tenant's liability under this lease." But if my subletter has no liability at all, then what was the point of the sublease?
I was also told that I need to find another subletter. Why is that my responsibility? I no longer have a key to the apartment, so I'm not even able to show the place to prospective renters. Please help...
