Montana Title 33. Insurance and Insurance Companies § 33-23-212. Notice required for cancellation--statement that insurer will specify reason upon request--exception

(1) A cancellation by an insurer of a motor vehicle liability insurance policy is not effective prior to the mailing or delivery to the named insured, at the address shown in the policy, of a written notice of the cancellation stating the date on which, not less than 45 days after the date of the mailing or delivery, the cancellation becomes effective. Other provisions of this code may not be construed as affecting the requirements provided in this subsection (1).

(2) A notice of cancellation of a policy to which 33-23-211 applies is not effective unless mailed or delivered by the insurer to the named insured at least 45 days prior to the effective date of cancellation. However, if cancellation is for nonpayment of premium, at least 10 days' notice of cancellation accompanied by the reason must be given. Unless the reason accompanies or is included in the notice of cancellation, the notice of cancellation must state or be accompanied by a statement that upon written request of the named insured, mailed or delivered to the insurer not less than 21 days prior to the effective date of cancellation, the insurer shall specify the reason for the cancellation.

(3) Subsection (2) does not apply to nonrenewal.
