Final answer:
The UCC does indeed cover accord and satisfaction by the use of an instrument known as a full payment check, which is a true statement.
Step-by-step explanation:
The statement that the Uniform Commercial Code (UCC) covers accord and satisfaction by the use of an instrument called a full payment check is true. Accord and satisfaction is a legal contract whereby both parties agree to different terms than what was originally agreed upon, and following these new terms fulfills the contract. A common example of this is when a debtor writes 'payment in full' on a check, and the creditor cashes the check. The UCC recognizes this as an accord (the new agreement) and satisfaction (the fulfillment of the new agreement) when certain conditions are met, effectively constituting a legally binding settlement of the debt.
