What Is an Unauthorized Transaction Dispute? (Credit Cards, Debit, ACH & More)
An unauthorized transaction dispute is your legal right to challenge charges you didn't make or approve, including fraud (e.g., stolen card data), scams (e.g., phishing), robbery-induced EFTs, or errors (CFPB). Covered under Regulation E (debit/ACHS/EFTs: $0-$50 liability) and FCBA (credit cards: full billing error protection).
- Types: Fraud (hacked accounts), criminal (theft), merchant errors (double charges).
- Legal basis: FTC guidelines, Visa Claims Resolution (post-2018), Mastercard Dispute Resolution (2020 rollout). Transaction disputes are rising, threatening merchant revenue (Sift report).
- Reg E vs FCBA: Debit offers quicker provisional credit but $50 cap; credit provides stronger dispute rights without liability.
EFTs via fraud/robbery qualify as unauthorized (CFPB FAQs).
