I wonder if that invalidates it entirely by them never having agreed to lease it to you in the first place (their lack of signature). If it's not on your copy, then it's meaningless to be on their copy. You are the one who needs to be in possession of their signature if they have made an obligation to you. You might have found your out, but I'm no expert, so bring that to the attention of a lawyer and see what they say.oldunion said:i just looked over my lease, and apparently they also have a copy, but they never signed my copy of the lease....it cant be this easy. I am about to see if they also have a copy because my roomate thinks they do, and this would be logical. Can i do anything since they didnt sign my copy? I dont remember what else i signed.
