Contracts and Sales Multistate Bar Practice Exam

In what situation can modifications under the UCC be considered ineffective?

1. If the buyer verbally agrees to changes

2. If the seller does not sign off on the change

3. If the terms of the contract are vague

4. If the seller was unaware of the modifications

The correct answer is: If the seller does not sign off on the change

Under the Uniform Commercial Code (UCC), modifications to a contract can be made without additional consideration, which is a key difference from common law contract principles. However, for these modifications to be effective, they typically need to be agreed upon by both parties involved. In this context, if the seller does not sign off on the change, it indicates a lack of mutual assent to the modification, thereby rendering it ineffective. The UCC emphasizes the importance of mutual agreement, particularly when it comes to significant alterations that can affect obligations, pricing, or delivery terms. If one party, in this case, the seller, does not consent to the new terms, the original contract remains in effect as initially agreed. This underscores the necessity of having both parties on the same page for modifications to be enforceable. The other scenarios involve factors that do not directly disrupt the mutual agreement process. Verbal changes may be recognized in certain contexts, while vagueness does not automatically invalidate a modification. Moreover, unawareness on the seller's part speaks to communication failures but doesn’t negate the need for mutual consent. Therefore, the requirement for the seller’s agreement is critical for the modification to take effect.
