Generally revise insurance laws relating to nonrenewals and cancellation of certain insurance policies

This bill updates Montana's insurance laws to strengthen protections for policyholders when insurers decide not to renew or cancel their insurance policies. It requires insurers to provide clearer reasons for nonrenewal decisions and extends the notice period from 45 to 90 days before a policy anniversary date, giving consumers more time to find alternative coverage. The legislation also prevents insurers from using simple inquiries about insurance terms as grounds for denying coverage or raising premiums, and it gives policyholders the opportunity to address specific reasons for nonrenewal before a policy expires. Additionally, the bill clarifies rules around premium increases and ensures insurers must disclose in advance if a single loss could lead to nonrenewal.
