Me. Stat. tit. 24-A § 2735
If any such policy contains a provision establishing, as an age limit or otherwise, a date after which the coverage provided by the policy will not be effective, and if such date falls within a period for which premium is accepted by the insurer or if the insurer accepts a premium after such date, the coverage provided by the policy will continue in force, subject to any right of termination, until the end of the period for which premium has been accepted. In the event the age of the insured has been misstated and if, according to the correct age of the insured, the coverage provided by the policy would not have become effective, or would have ceased prior to the acceptance of such premium or premiums, then the liability of the insurer shall be limited to the refund, upon request, of all premiums paid for the period not covered by the policy. [1969, c. 132, §1(NEW).]
