Michael Scotto borrowed $ 2,970 from Cindy Vinueza. Both of their signatures appeared at the bottom of a note that stated, “I Michael Scotto owe Cindy Vinueza $ 2,970 (two thousand and nine- hundred & seventy dollars) & agree to pay her back in full. Signed on this 26th day of September 2009.” More than a year later, Vinueza filed a suit against Scotto to recover on the note. Scotto admitted that he had borrowed the funds, but he contended—without proof—that he had paid Vinueza in full. Is this note negotiable? Which party is likely to prevail? Why?
