Vis major (Latin for “superior force”) is a legal term used to describe an irresistible natural or human event that causes damage or disruption and that neither party could have prevented even with the utmost care. Common synonyms are “act of God,” “natural disaster,” and “force majeure.” Vis major typically appears in contracts and insurance language to excuse or limit a party’s liability and performance obligations when unforeseeable, uncontrollable events occur (source: Investopedia).
Understanding Vis Major
– Nature of events: Examples often include hurricanes, tornadoes, floods, earthquakes, war, riots, strikes, and widespread supply‑chain interruptions caused by third parties. Whether human‑caused events (war, riots, strikes) are covered can depend on the exact wording of a contract and the governing jurisdiction.
– Purpose in contracts: Force majeure/vis major clauses allocate the risk of extreme events. They commonly suspend performance during the event, extend deadlines, or (if the event is permanent or long-term) allow termination without liability.
– Limits: Vis major does not excuse negligence, fraud, or ordinary/expected events (for example, routine seasonal rainfall or foreseeable minor delays). Parties are typically still expected to take reasonable mitigation steps.
– Jurisdictional variation: Definitions and judicial interpretations vary by country and state; therefore, many international contracts explicitly define which events qualify as vis major.
Events Vis Major Does Not Cover
– Negligence, malfeasance, intentional acts by a contracting party.
– Normal, expected occurrences (e.g., seasonal weather within historical norms).
– Problems caused solely by a party’s failure to plan, insure, or mitigate foreseeable risks (e.g., lack of maintenance or inadequate contingency planning).
– Events specifically excluded by contract language.
Special Coverage for Vis Major (Insurance Considerations)
– Standard policies: Many standard property or casualty policies exclude losses from events commonly considered vis major (earthquakes, floods, hurricanes). That means the insured may bear those costs unless they have separate coverage.
– Riders and separate policies: Flood, earthquake, and hurricane damage can often be insured with separate policies or endorsements (riders). These typically cost extra and may be very expensive in high‑risk regions.
– Auto insurance: Comprehensive automobile coverage often covers damage from falling trees, collisions with animals, or other non-collision perils commonly viewed as vis major events—if the policy includes comprehensive coverage.
– Pricing and availability: Insurers may offer coverage at reasonable rates where the risk is low; rates increase or coverage becomes limited as the likelihood of a payout rises.
– Claims: A finding that an event was a vis major can also affect legal liability in lawsuits, potentially relieving defendants of responsibility if a court accepts the vis major defense.
Practical Steps — For Businesses (contracting and risk management)
1. Audit existing contracts
• Identify force majeure/vis major clauses and note what events are included, excluded, and the procedural requirements (notice, documentation, cure periods).
2. Define the clause clearly
• Explicitly list covered events (natural disasters, pandemics, war, strikes, government actions, supply‑chain disruptions).
• Specify duration, notice requirements, mitigation obligations, and consequences (suspension, extension, termination, allocation of costs).
3. Add procedural safeguards
• Require prompt written notice, proof of impossibility, and periodic updates.
• State whether obliging parties must attempt reasonable mitigation and provide evidence.
4. Allocate risk and remedies
• Decide who bears financial risk and when (e.g., relief from performance vs. termination and restitution).
• Consider liquidated damages, price adjustments, or alternative supply requirements.
5. Maintain a force majeure playbook
• Assign responsibilities, communication templates, internal escalation procedures, and a decision framework for invoking clauses.
6. Strengthen supply‑chain resilience
• Diversify suppliers, maintain safety stock, use dual‑sourcing, and build geographically distributed capabilities.
7. Review insurance coverage
• Purchase specific riders or separate policies for earthquake, flood, business interruption, and political risk if needed.
8. Seek legal counsel
• Have counsel review draft clauses to ensure enforceability across jurisdictions and to tailor obligations (notice, mitigation, burden of proof).
Practical Steps — For Individuals and Property Owners
1. Review your insurance policies
• Identify exclusions for flood, earthquake, hurricane, or other catastrophic perils. Note deductibles and coverage limits.
2. Buy specialized coverage if necessary
• Purchase flood or earthquake insurance if you live in a hazard area; consider higher limits or separate riders for catastrophic loss.
3. Prepare documentation and take preventive measures
• Inventory belongings, photograph property, maintain receipts and records, and implement mitigation measures (storm shutters, secured roofing, tree trimming).
4. Emergency planning
• Develop evacuation plans, keep an emergency kit, and store important documents digitally and offsite.
5. If damage occurs
• Notify insurer immediately, document damage with photos/videos, keep receipts for temporary repairs, and keep a log of communications.
6. Understand automobile coverage
• Add comprehensive coverage for protection against non-collision perils (fallen trees, animals).
Practical Steps — If You Need to Invoke a Vis Major Clause or File a Claim
1. Read the clause/policy carefully
• Note notice periods, documentation requirements, mitigation obligations, and whether the event is covered.
2. Provide timely written notice
• Many contracts demand prompt written notice as a condition of relief. Include date, nature of event, and statement of impact.
3. Document causation and impact
• Keep contemporaneous records, photos, supplier correspondence, official government declarations, and expert reports if appropriate.
4. Mitigate loss
• Take reasonable steps to limit the damage (temporary repairs, alternate suppliers) and document those efforts.
5. Communicate proactively
• Update the counterparty or insurer regularly with status reports and anticipated timelines.
6. Preserve evidence and communications
• Maintain emails, logs, invoices, and receipts. These will be crucial if a dispute arises.
7. Get legal/insurance advice early
• If exposure is substantial or a counterparty challenges the invocation, consult counsel and insurance professionals.
Sample Considerations When Drafting a Force Majeure/Vis Major Clause (for negotiation)
– Start with a clear definition: list specific perils and include “other events beyond reasonable control” with examples.
– Include affirmative obligations: notice timing, required documentation, steps to mitigate loss, duty to resume performance.
– Consider an economic hardship carve‑out: whether extreme price changes or supply failures qualify.
– State remedies: suspension of performance, extension of deadlines, right to terminate after X days, allocation of costs, or alternative dispute resolution.
– Clarify the standard of proof and burden of proof for invoking the clause.
Key Takeaways
– Vis major (force majeure/act of God) covers unforeseeable, uncontrollable events that prevent contractual performance, but exact scope depends on contract language and jurisdiction.
– Vis major does not excuse negligence, intentional acts, or normal/foreseeable events.
– Insurance often excludes vis major perils unless you buy specific riders or separate policies (flood, earthquake, hurricane).
– Practical preparedness—clear contract drafting, insurance audits, mitigation planning, and good documentation—reduces financial and legal exposure.
– Always consult legal and insurance professionals when drafting clauses, negotiating contracts, or submitting claims.
