In force since 1 October 2024.

An enforcement supervision rule binding private bodies.

As of 27 August 2026.

What it requires

Expect MCDPA violations to be enforced exclusively by the Montana Attorney General, never by a private plaintiff.
Do not assume a notice-and-cure opportunity before an enforcement action. As of October 1, 2025, the Attorney General may proceed directly to a civil penalty without a mandatory cure step.

What this law does

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

The Montana Attorney General has exclusive authority to enforce MCDPA; the chapter creates no private right of action. Civil penalties run up to $7,500 per violation.

As currently codified, section 30-14-2817 (Enforcement) contains no notice-and-cure text in its five subsections following the S.B. 297 amendment, yet section 30-14-2820(2) cross-references a 'thirty-day period described in 30-14-2817(3),' which as read describes the Attorney General's civil-investigative-demand authority rather than a cure mechanism.

That cross-reference is an open citation-accuracy question rather than a resolved one; the operative, secondary-corroborated finding is that no mandatory pre-action cure right survives as of October 1, 2025, so a first violation can lead directly to a penalty.
