Which clause in a contract protects parties from unforeseen events disrupting fulfillment?

The correct choice is the force majeure clause, as it specifically addresses unforeseen events or circumstances that prevent one or both parties from fulfilling their contractual obligations. This clause typically includes natural disasters, wars, labor strikes, or other extraordinary events that are beyond the control of the parties involved. By including a force majeure clause in a contract, the parties can delineate what types of events qualify for relief from performance obligations and set forth the procedures for notification and potential resolution.

In contrast, an indemnity clause generally provides for one party to compensate the other for losses or damages incurred, but it does not specifically address disruptions caused by external unforeseen events. The capacity clause relates to the legal ability of the parties to enter into a contract, ensuring that they are of sound mind or of legal age to agree, which is unrelated to disruptions in contract fulfillment. The parol evidence clause restricts the introduction of any external evidence to contradict or modify the written terms of a contract, but it does not address unforeseen events affecting performance. Thus, the force majeure clause is uniquely positioned to protect parties from the impact of unexpected disruptions.
