What is the purpose of the 'incontestability clause' in a life insurance policy?

The incontestability clause provides that once a life insurance policy has been in force for a specified period — most commonly two years — the insurer can no longer contest the validity of the policy or deny a death claim based on misstatements or omissions in the application. This protects beneficiaries from having a long-standing policy challenged after the insured's death. During the initial contestable period, the insurer may investigate and contest based on material misrepresentation. The exact scope and exceptions (such as for fraud) vary by state, but the two-year incontestability standard is a widely tested policy provision.
