The incontestability period of an insurance policy is one of the most important parts of a life insurance contract.
Life insurance policies must contain an incontestability clause — a provision that the policy will be incontestable after it has been in force during the lifetime of the insured for two years from its date, except for nonpayment of premiums. This requirement is found in Texas Insurance Code, Section 1131.104. It is also found it sections 705.101 thru 705.105. The effect of these clauses is to limit the misrepresentation defenses so they can apply only during the first and second years.
As stated in the 1972, Texas Supreme Court opinion styled, Minnesota Mutual Life Insurance Company v. Morse, the purpose of the incontestability clause is to protect the insured from a contest as to the validity of the policy after the set period has expired.
