Laws and Rules

State laws that govern the insurance and securities industries can be found in Montana Code Annotated. The MCA is a compilation of existing Montana laws. Laws are also known as statutes and can only change when the legislature is in session. The MCA is updated a few months after each legislative session.

Administrative rules are regulations establishing how an agency implements a law. Unlike statutes, which change only when the legislature is in session, administrative rules change through an agency process, which allows more flexibility. Agencies are given rulemaking authority through the legislative process (2-4-101, MCA).  Learn more about proposed rules and the adoption process of an Administrative Rule on the Montana Secretary of State Website.

In addition to our regulatory function, the securities department has the authority to investigate violations of the Securities Act of Montana. We have jurisdiction over fraudulent securities transactions and have broad enforcement authority to file administrative and injunctive actions and to refer criminal matters to the county attorneys.


Our insurance department is charged by statute with regulating the business of insurance to guarantee it is conducted in accordance with the law and in such a way as to protect policyholders and the general public.
