Drafted with AI from the cited sources under the direction of UnGovr staff. UnGovr holds editorial responsibility for this page.

A person or business required to notify Montana residents of a breach of security must simultaneously submit an electronic copy of the notification to the Attorney General's consumer protection office; notice must be made without unreasonable delay, consistent with law-enforcement needs and the measures necessary to determine the breach's scope. This provision is in force under the current codified text; no dated original commencement is established, so no effective date is recorded here.
