Mont. Code Ann. § 33-15-415

Each individual life or disability insurance policy, except a single-premium nonrenewable disability policy, issued for delivery in this state or issued after January 1, 1996, must contain a notice stating in substance that if the person to whom the policy is issued is not satisfied for any reason, the person may return the policy within 10 days of its delivery or a longer period if provided by the policy and have refunded directly to the person the premium paid. A policy returned pursuant to this section is void from the beginning.
