When a wildfire, port closure, or government order makes a contract impossible to perform, the first thing anyone reads is the force majeure clause. Many California businesses signed that clause as boilerplate and discovered during the pandemic that its exact wording decides who absorbs the loss. Here is what force majeure actually covers in California — and what it does not.
What a force majeure clause does
A force majeure clause allocates the risk of extraordinary events that neither party can control. When a qualifying event prevents performance, the clause typically suspends the affected party's obligations for the duration of the event, and often allows either party to terminate if the disruption lasts beyond a stated period. Without it, the parties are left to statutory and common-law doctrines — impossibility, impracticability, and frustration of purpose — which are narrower and far less predictable than a well-drafted clause.
What the clause is not: a general escape hatch from a deal that has become unprofitable. Courts consistently refuse to stretch force majeure to cover ordinary business risk.
California courts read the list literally
Force majeure clauses are construed narrowly, and the list of triggering events matters more than the label. Three principles drive most disputes:
- Listed events control. If the clause names earthquakes, strikes, and war, a supply-chain collapse caused by something else may not qualify. Courts start — and often end — with the words the parties chose.
- Catch-all language is read in context. A phrase like "or other events beyond the parties' reasonable control" is generally interpreted in light of the specific events listed before it, not as an unlimited safety net.
- Expense is not impossibility. That performance became more costly or less profitable is not force majeure. California authority requires something close to prevention — an insurmountable interference — before performance is excused, and mere increased expense qualifies only in extreme and unreasonable circumstances.
Civil Code § 1511: the statutory backdrop
Even without a force majeure clause, California law excuses performance in limited situations. Civil Code § 1511 relieves a party from performing when performance is prevented or delayed by operation of law or by an "irresistible, superhuman cause" — the statutory cousin of an act of God. Related common-law doctrines excuse performance that has become genuinely impossible or impracticable, or where the contract's fundamental purpose has been destroyed.
These defaults are real but thin. They rarely cover labor shortages, vendor failures, or price spikes, and they leave open questions — notice, duration, allocation of deposits — that a contract clause can answer in advance. That is why the clause is worth negotiating rather than skimming.
Causation, foreseeability, and mitigation still matter
Invoking force majeure is not automatic. The party claiming it must show that the qualifying event actually caused the failure to perform — not merely that the event occurred somewhere in the background. Depending on the clause, courts may also ask whether the event was foreseeable at signing (a recurring issue for pandemic-era contracts signed after early 2020) and whether the invoking party took reasonable steps to work around the disruption. Contractual notice requirements are enforced as written: a clause that requires written notice within ten days of the event can defeat an otherwise valid claim if the notice went out late or not at all.
A drafting and negotiation checklist
Whether you are the party more likely to invoke the clause or the one more likely to receive the notice, focus on these points:
- The event list. Include epidemics, public-health orders, government action, cyberattacks, utility and telecommunications failures, and supplier failures if those risks are real for your business.
- Payment carve-out. Most clauses should state that force majeure never excuses the obligation to pay money already owed.
- Notice and updates. Set a clear deadline for written notice and require ongoing status reports.
- Mitigation duty. Require the affected party to use commercially reasonable efforts to resume performance.
- Exit trigger. Allow either party to terminate if the event continues past a defined period — 30, 60, or 90 days — and say what happens to deposits and prepaid fees.
Because these clauses are enforced according to their precise text, small wording choices carry real money. A California business contracts attorney can tailor the event list and mechanics to the risks your business actually faces — and, if a counterparty has already invoked force majeure against you, evaluate whether the claim holds up.
