Junior owes creditor Iba $1,000, which is due and payable on June 1. Junior has been in a car accident, has missed a great deal of work, and consequently will not have the funds on June 1. Junior’s father, Fred, offers to pay Iba $1,100 in four equal installments if Iba will discharge Junior from any further liability on the debt. Iba accepts. Is this transaction a novation or an accord and satisfaction? Explain.
