“Material misrepresentation” in insurance refers to the act of providing false, incorrect, or incomplete information about material facts during the insurance application process or when filing a claim. Material facts are details that could influence an insurer’s decision to underwrite a policy, determine the policy terms, or calculate premium rates. Misrepresentation becomes “material” when the information in question is significant enough that, had the insurer known the true facts, it might have declined to issue the policy, offered it under different terms, or set a different premium rate. It’s the kind of misrepresentation that would have changed the insurer’s decision, the kind that can cost you your coverage.

Key aspects of material misrepresentation include:

  • Impact on insurance contracts

    Material misrepresentation can lead to severe consequences for the policyholder, including the voiding of the insurance policy, denial of claims, or cancellation of coverage. This is because the insurance contract is based on the principle of utmost good faith, requiring both parties to deal honestly and disclose all relevant information accurately. For life insurance, once a policy has been in force for two years, the insurer generally can’t void it for a misrepresentation unless there was fraud; Quebec’s Civil Code has a similar two-year rule. A misstated age generally doesn’t void a life policy: the benefit is adjusted to what the premium would have bought at the correct age.

  • Intentional vs. unintentional

    Misrepresentations can be either intentional (deliberate deception to secure lower premiums or more favourable terms) or unintentional (honest mistakes or oversights). While the consequences can be severe in both cases, insurers often assess the intent behind the misrepresentation when deciding on the appropriate action.

  • Examples of material facts

    Material facts that must be accurately represented include personal information (such as age and medical history), and lifestyle choices (such as smoking or engaging in high-risk activities).

  • Legal and contractual implications

    The discovery of material misrepresentation can lead to legal disputes between the insurer and the insured, especially if claims are denied or policies are rescinded as a result. Insurers may require policyholders to verify or attest to the accuracy of the information provided to mitigate this risk.
