Michigan Compiled Laws, Chapter 500. Insurance Code of 1956 § 500.4058

Sec. 4058. This section shall apply only to policies of life insurance other than industrial life insurance issued prior to the operative date of section 4060  1 (the standard nonforfeiture law).

The nonforfeiture benefit referred to in section 4024  2 shall be available to the owner of the policy in event of default in premium payments, after premiums shall have been paid for 3 years and shall be a stipulated form of insurance, the net value of which shall be at least equal to the reserve at the date of default on the policy and on any dividend additions thereto, specifying the mortality table and rate of interest adopted for computing such reserves, less a sum not more than 2 1/2 % of the amount insured by the policy and of any existing dividend additions thereto, and less any existing indebtedness to the insurer on the policy. Such provision shall stipulate that the policy may be surrendered to the insurer at its home office within 1 month from date of default for a specified cash value at least equal to the sum which would otherwise be available for the purchase of insurance as aforesaid and may stipulate that the insurer may defer payment for not more than 6 months after the application therefor is made. This section shall not be applicable to term insurances of 20 years or less.
