For years, force majeure clauses sat near the back of contracts, rarely read and rarely invoked. Recent global disruptions changed that, putting these provisions — which excuse performance when extraordinary events strike — squarely in the spotlight. Businesses learned that whether such a clause actually helps depends heavily on its specific wording. This guide explains what force majeure clauses do, why they matter more than ever, and how to make them work. It is general information; whether a clause applies to a given situation is fact- and law-specific.

We help businesses get this right from the start. This is general information, not advice on a specific situation.

The force majeure clause you ignored is the one you suddenly needed.

What force majeure clauses do

A force majeure clause addresses what happens when extraordinary events beyond a party’s control — such as natural disasters, major disruptions, or other specified events — make performance impossible or impractical. As the Legal Information Institute’s overview of law.cornell.edu reflects, such a clause can excuse or delay a party’s performance in defined circumstances, rather than treating non-performance as a breach. In effect, it allocates the risk of extraordinary disruptions. Without such a clause, a party unable to perform due to an extraordinary event may still be in breach, subject to limited legal doctrines. The clause provides a contractual answer to “what if something extraordinary makes performance impossible.”

Whether it helps comes down to how it was written.

Why they matter more than ever

Recent widespread disruptions brought force majeure clauses to prominence, as businesses across the economy suddenly faced situations where they couldn’t perform — and turned to these clauses for relief. The experience taught a clear lesson: whether a force majeure clause actually applies to a given disruption depends heavily on how it’s worded. Some businesses found their clauses covered the situation; others found theirs didn’t, because the wording was too narrow or didn’t contemplate the events that occurred. This real-world stress test elevated force majeure from an ignored boilerplate provision to one that businesses now recognize as genuinely important to get right.

Wording is everything

The central lesson is that the specific wording of a force majeure clause determines whether it helps. Key elements include which events are covered (specific lists, general catch-all language, or both), what effect on performance is required (impossibility, impracticality, or hindrance), what the consequences are (excused or merely delayed performance), and any notice or mitigation requirements. As a law.cornell.edu provision, it’s interpreted according to its terms, so a clause that lists relevant events broadly and clearly is far more useful than a narrow or vague one. Whether a clause covers a particular disruption is ultimately a question of its wording and the applicable law.

Making the clause work for you

Given how much wording matters, force majeure clauses deserve deliberate drafting and review rather than boilerplate treatment. Businesses should consider what disruptions could realistically affect their performance, ensure the clause’s covered events and effects are appropriate, and understand the consequences the clause provides. When a potential force majeure situation arises, whether the clause applies — and what steps (like notice) are required — should be assessed against the specific wording and facts. Because these clauses can be decisive when extraordinary events strike, and their effect turns on their terms, drafting and interpreting them with legal guidance helps ensure they actually provide the protection intended when it’s needed.
