My roommate decided to move out.. she informed me yesterday and said she is moving into her new apartment March 1st. She said she is trying to find a sublet but also said that she is moving March 1st regardless if she finds one or not and refuses to pay two rents--so after March 1st it would be "my problem" and not hers---which I know that legally that cannot be correct. We are both on the lease so I know that she will be held liable but my question is--- legally she has to give how much time notice? Also, she is trying to find a roommate but what if I don't like them. The apartment complex I live at said that she cannot sign someone onto the lease in her place until I approve and sign that it is O.K. How picky can I be when choosing a roommate? She said if they pass the credit check that should be all that matters but I think deciding to live with a person for 6 months (the remainder of the lease) should be based on more than if their credit is good.
She also already put down a deposit to the other complex and said I would be liable if I refuse roommates she finds and she looses the deposit for the other complex because she wouldn't be able to move. What are my rights in Colorado to refuse a roommate and since a roommate cannot move in until I sign that it is O.K.-- is there a time set on this? How long is she legally bound to this agreement until it does become "my problem"?
(Also, I am helping her out to find a replacement for her.. but to find someone in a week is quite a short time to find a new roommate).
