Rule: Generally, consideration is required to modify a contract. Under the common law, modification to a contract is unenforceable unless there is consideration.
Analysis: Under the common law, the contractor had a pre-existing duty to start on time. Therefore, the modification was unenforceable for lack of consideration.
Exceptions:
Common Law Rule:
Some new or different consideration is needed to support the promise because the promisor was already legally obligated to perform.
U.C.C. Rule:
The U.C.C. has eliminated the pre-existing duty rule; all U.C.C. contract modifications (oral or in writing) are enforceable if they are done in good faith and do not violate the statute of frauds.
Unforeseen Difficulties:
When the difficulties were both unforeseen and neither party had assumed the risk, then the contract can be rescinded. Therefore, promising to give something new for doing the same act as compensation for the unforeseen difficulty is good consideration.
Example:
Flint contracts with Stone for Stone to dig out the crawl space under Flint’s house and to build a full basement for $25,000. Stone brings in a backhoe and begins excavating the earth under Flint’s house. Unbeknownst to either party, there is bedrock under Flint’s house that cannot be removed by the backhoe. In order to create sufficient space for the basement, some bedrock would have to be pulverized with jackhammers and then removed by the backhoe. Flint agrees to pay Stone the additional $12,000 that it would cost Stone to rent the jackhammers and to hire the individuals necessary to remove the bedrock.
Honest Dispute:
If there is a good faith dispute over terms and duties previously promised, then new consideration to do the same act is good consideration for the purpose of resolving the dispute. This rule is true even if the party that in good faith raised the dispute was wrong. A modifying agreement related to solving an honest dispute over a legal duty is ordinarily enforceable because the compromise to each party is a detriment.
Pre-Existing Duty Owed to Third Party:
Majority View: When a pre-existing duty is owed to a third party, the new promise constitutes consideration under Restatement 2d, §73.
Voidable Obligation:
A promise to perform a voidable obligation (i.e., ratification) is enforceable despite the absence of new consideration. Thus, an infant’s ratification of a contract upon reaching majority is enforceable without new consideration, as is a defrauded person’s promise to go through with the tainted contract after learning of the fraud.
Question:
An employer enters into a contract with a driver to have the driver take a truck with supplies to the city for $1,000. While the driver was fueling his truck and preparing for his trip, a hitchhiker asks the driver where he is going. The driver responds that he is going to the city. The hitchhiker says that is where he needs to go, and offers to pay the driver $300 if he takes him along for the trip. The driver agrees and drives to the city, dropping the hitchhiker off where the driver unloads his truck. However, the hitchhiker leaves and refuses to pay the driver the $300 as agreed.
Can the driver enforce the agreement between the driver and the hitchhiker?
Answer: Yes, the driver can enforce the agreement.
Issue: The issue is whether there was valid consideration when the driver promised to drive the hitchhiker to his destination in exchange for $300, even though the driver already had to drive to that location.
Rule: Consideration is a bargained for exchange. When a pre-existing duty is owed to one party, a new promise towards another party constitutes valid consideration.
Analysis: Yes. The driver has a pre-existing duty to his employer, but that duty only exists between the driver and the employer. The driver does not have a pre-existing duty to the hitchhiker so promising to take him along for the trip was new consideration. The driver’s agreement with the hitchhiker is completely independent. Just because he was already going that way does not mean there was no consideration.
Question:
A professional wrestler entered into a written agency contract with an agent, who agreed to try to get the wrestler’s picture on a variety of food products. The wrestler promised that the agent would have the exclusive right to promote the wrestler on food product lines. They agreed that the wrestler would receive 70% of the proceeds and the agent would receive 30%. The agent was able to persuade the makers of a breakfast cereal to put the wrestler’s picture on the cereal boxes. Shortly after the agent confirmed the cereal deal with the cereal manufacturer, the wrestler and the agent agreed orally that henceforth the wrestler would receive 50% of the proceeds, including proceeds from the cereal deal, and the agent would receive the other 50%. The wrestler received a $10,000 check from the cereal deal, and he promptly sent the agent a check for $3,000. The agent demanded an additional $2,000, but the wrestler refused to pay.
If the agent sues wrestler for the $2,000, which party is most likely to prevail?
A. The wrestler because of the parol evidence rule.
B. The agent because consideration is not required for a modification.
C. The wrestler because the agent had a pre-existing duty to secure food product promotions for the wrestler.
D. The wrestler because an exclusive contract requires that the party given the privileges of exclusivity use his best efforts.
Answer (C) is correct.
Issue: The issue is whether the modified contract between the agent and the wrestler is enforceable.
Rule: Under the common law, a modification of a contract is enforceable if there is consideration because the parties were already under a pre-existing legal duty to perform.
Analysis: Here, there was no new consideration provided when the agent and wrestler modified their contract by stating that the each of them would equally split the proceeds from the deals. Thus, the modification is not enforceable. Instead, the originally agreed upon contract, which provided for the agent to receive 30% of the proceeds from each deal, is enforceable. The agent is thus not entitled to the additional $2,000.
(C) is correct because of the preexisting duty rule (A) is incorrect because the parol evidence rule does not apply to subsequent modifications. (B) is incorrect because that is the U.C.C. rule, which does not apply here because there was no sale of goods involved. (D) is incorrect because exclusivity of a contract is irrelevant to the issue of whether a modified contract is enforceable. This is irrelevant to the main issue in this question.
