Ann and the Incomplete Check Jack gave his girlfriend, Ann, a check, but he left the amount incomplete. The check was given as partial payment for a $2,500 loan that Ann made to Jack three months prior. The amount was left blank because Jack was in a hurry. He signed a blank check and told Ann to fill out the check for $500. Ann needed to make her $950 car payment. Ann wrote the check for $950 and cashed it at Jack's bank. Jack was upset when he found out about it. He broke up with Jane and demanded that she immediately pay him the $450 difference. Jane refused claiming Jack owed her more than that. Jack sued Jane for the $450. Will Jack be successful? Discuss why or why not. Does Jack and Ann’s prior relationship influence the case in any way? Discuss why or why not.
