Montana Deepfake Laws: AI Images, Voice Cloning & Penalties (2026)

Frequently Asked Questions

Is it illegal to make a deepfake of someone in Montana?

It depends on the purpose and content. Nonconsensual intimate deepfakes are criminal under MCA 45-8-213 (as amended by HB 514, effective October 1, 2025) and MCA 45-5-640 (SB 413, effective May 12, 2025). Election deepfakes distributed without a disclosure within 60 days of a Montana election violate SB 25. Unauthorized commercial AI replicas of a person's voice or likeness violate HB 513 starting January 1, 2026. Purely satirical or clearly labeled content generally is not covered.

Is deepfake porn a crime in Montana?

Yes. MCA 45-8-213, amended by HB 514 (effective October 1, 2025), criminalizes the publication or distribution of digitally fabricated intimate images without the depicted person's consent when done to extort, harm, or threaten. A first offense is a misdemeanor; subsequent offenses are felonies with up to 5 years in prison and fines up to $25,000. The separate offense of disclosing explicit synthetic media (MCA 45-5-640) carries up to 10 years in state prison when the person depicted is a minor. The federal TAKE IT DOWN Act provides an additional criminal layer.

Can I sue someone for a deepfake in Montana?

For unauthorized AI voice or likeness replicas used commercially, HB 513 (codified at MCA 30-14-1714, effective January 1, 2026) creates a civil cause of action for the actual damages suffered plus any profits the violator made from the unauthorized use. The statute sets no minimum statutory damages figure. For election deepfakes, SB 25 allows candidates to seek injunctive relief and up to $10,000 in damages. NCII deepfakes under MCA 45-8-213 are primarily criminal rather than civil, though related conduct may support other tort claims.

Are AI voice clones illegal in Montana?

Unauthorized AI voice clones used for commercial purposes without consent will be illegal under HB 513 (MCA 30-14-1714) starting January 1, 2026, and the person depicted can sue for actual damages plus any profits the violator made from the unauthorized use. AI-generated voice robocalls without prior express consent are already illegal nationwide under the FCC's February 2024 ruling applying the TCPA. Montana's HB 513 is modeled on Tennessee's ELVIS Act, the national archetype for voice clone legislation.

What is Montana's election deepfake law?

Montana SB 25 (2025) prohibits distributing AI-altered depictions of candidates within 60 days of a Montana election unless the communication clearly states the image was substantially edited by AI. Enforcement runs through the Commissioner of Political Practices: a first sufficiency finding carries civil penalties, a second triggers misdemeanor prosecution (fine up to $500, up to 6 months in jail), and a third or later finding triggers felony prosecution (fine up to $5,000, up to 2 years in state prison). Candidates can also seek expedited injunctive relief, actual damages, and up to $10,000 in punitive damages. The law faces an ongoing First Amendment challenge in federal court.

Does Montana law cover AI-generated CSAM?

Yes. HB 82 (signed April 7, 2025; effective July 1, 2025) amended MCA 45-5-625 to expressly criminalize computer-generated and AI-fabricated child sexual abuse material. Federal law (18 U.S.C. 2256(8)(B)) independently covers AI-generated images indistinguishable from real minors under the PROTECT Act of 2003, regardless of state law.

What is the TAKE IT DOWN Act and does it apply in Montana?

The TAKE IT DOWN Act (Public Law 119-12, signed May 19, 2025) is a federal law that applies in all 50 states, including Montana. It makes it a federal crime to knowingly publish nonconsensual intimate visual depictions including AI deepfakes, with penalties up to 2 years in prison (3 for victims who are minors). Platforms must remove flagged content within 48 hours of a victim notice by May 19, 2026.

Are the DEFIANCE Act and NO FAKES Act law in Montana?

No. Both bills are pending proposals in the 119th Congress as of mid-2026. The DEFIANCE Act would create a federal civil cause of action for sexual deepfakes; the NO FAKES Act would create a federal right of publicity against unauthorized AI voice and likeness replicas. Neither has been enacted. Do not rely on either as current law.

Updates

Corrected the civil remedy under Montana's AI likeness law (MCA 30-14-1714), which provides actual damages plus the violator's profits and no $50,000 statutory minimum, clarified that the FTC enforces only the TAKE IT DOWN Act's platform removal duty while the criminal offense is prosecuted by the Justice Department, and fixed the NO FAKES Act bill number.
