Montana Credit and Debit Card Consumer Protection Laws in 2026
Federal Regulation Z (12 CFR 1026) and Regulation E (12 CFR 1005) set the floor for card-dispute rights everywhere in the US. Montana's Montana Consumer Protection Act (Mont. Code Ann. §§ 30-14-101 to 30-14-142) provides state-level remedies that can go further, including additional private causes of action, mandatory damages, and the right to file with the Montana AG Consumer Complaints.

Montana AG Consumer Complaints ↗Montana's UDAP Statute: Montana Consumer Protection Act
Mont. Code Ann. §§ 30-14-101 to 30-14-142Montana Consumer Protection Act is Montana's primary consumer-protection statute covering unfair and deceptive acts and practices (UDAP) in trade or commerce. It provides consumers with remedies in addition to (not instead of) federal protections under Regulation Z and Regulation E.
Key points
Montana CPA modelled on the FTC Act; prohibits unfair methods of competition and deceptive acts.
How Federal Law and Montana Law Interact
Federal preemption does not eliminate state UDAP claims for credit and debit card disputes. The Truth in Lending Act (TILA) and Electronic Fund Transfer Act (EFTA) expressly preserve state consumer-protection laws that are not inconsistent with the federal statutes.
For credit card disputes: If your issuer violates your rights under Mont. Code Ann. §§ 30-14-101 to 30-14-142, you may have a claim under both Regulation Z 12 CFR 1026.13 (federal billing-error claim) and the Montana Consumer Protection Act (state UDAP claim). State claims often provide attorney fees and minimum statutory damages that federal law does not.
For debit card disputes: Regulation E 12 CFR 1005.11 sets the federal dispute process and timeline. If your bank fails to investigate within the required period (10 business days for EFT errors) or wrongly denies your claim, that failure may independently constitute an unfair or deceptive act under Mont. Code Ann. §§ 30-14-101 to 30-14-142, giving you a state-law remedy.
Practical tip
File your dispute with your card issuer first (required by Reg Z and Reg E). If denied, file with the Montana AG Consumer Complaints and the CFPB simultaneously. Small claims court in Montana (up to $7,000) is available without an attorney and costs $30-$100 to file.

Filing a Card Dispute in Montana: Step-by-Step
Dispute directly with your issuer
Required first step under both Reg Z (credit) and Reg E (debit). Send written notice to the address on your billing statement. For credit, the dispute letter must reach the issuer within 60 days of the statement date showing the charge.
Get the result in writing
Your issuer must acknowledge a credit billing-error claim within 30 days (12 CFR 1026.13(b)(2)) and resolve it within two billing cycles. For a debit EFT error, the bank must complete investigation within 10 business days (12 CFR 1005.11(c)(1)).
File with the CFPB
Submit at consumerfinance.gov/complaint. The CFPB forwards complaints to the issuer, who must respond. CFPB complaint data is public; issuers take them seriously.
File with the Montana AG Consumer Complaints
Montana's Montana Consumer Protection Act (Mont. Code Ann. §§ 30-14-101 to 30-14-142) gives the AG additional enforcement authority. File at: https://dojmt.gov/consumer/consumer-complaints/
Consider small claims court (up to $7,000)
If the dispute amount is within Montana's small claims limit, file in your local small claims court. No attorney required; filing fees are typically $30-$100. Bring your written dispute, the issuer's written denial, and any documentation of your loss.
