My current roommate and I found a third roommate to pay a portion of the rent and utilities. We did not put her on the lease so if things did not work out we could ask her to leave. We didn't even get to sign a written agreement. We had a verbal agreement however that she was to pay four hundred a month plus split utilities. We made a deal that she could pay three fifty for her first, month November. At the last minute she decided not to move in, a week before December. Now she's asking for her money back in full or she will take us to court. Does she have a case?
