Hi, on January 20, 2009, I lent a friend $2,000 to go to Greece. He wrote a handwritten IOU, for the entire sum, stating the entire sum to be repaid within 3 months. In March he paid me $350.00 and in May $100.00. He now have a balance of $1.550. He won't answer my calls and will not enter any correspondance. Is small claims court my answer ? I live in NJ, if that is of any inportance.
