I recently had a roommate living with me and my boyfriend. He did not pay any bills and before we kicked him out, he signed a promissory note which was dated and notarized. Accorsing to the note, he is supposed to pay the money back in weekly installments. He also has until June of 2007 to pay back the full amount. However, he is refusing to pay anything back and hasn't made any payments. Is there anything I can do to make him pay or do I have to wait until June to do something about it?
