... not working, has no money, and is not paying any of the bills (barely even makes enough for rent), eating all of our food. Enough is enough. 2 other roommates and myself have decided that we need her to leave! are we legally allowed to kick her out? She hasn't signed a lease or anything and the one girls mom is the landlord...
