What Is an Unauthorized Transaction Dispute & Your Legal Rights in 2026
An unauthorized transaction is any charge, withdrawal, or payment you didn't approve – from fraudulent credit card swipes to hacked ACH transfers or PayPal scams. Under the Fair Credit Billing Act (FCBA), you have zero liability for unauthorized credit card charges if reported within 60 days of the statement date. For debit cards and ACH, Regulation E limits losses to $50 (or $500 if not reported promptly) and requires banks to investigate within 10 days.
Key 2026 Protections:
- Visa/Mastercard Guidelines: Zero liability for fraud; disputes must be filed within 120 days, but act in 60 for best results.
- CFPB & FTC Rules: File complaints via CFPB templates for escalation; FTC identity theft affidavits strengthen claims.
- Stats: FTC 2025 report shows $10B+ losses, but 85% of timely disputes result in full reimbursement (CFPB data).
Mini Case Study: Sarah spotted a $1,200 unauthorized Visa charge. Using our template, she disputed within 45 days – Visa reversed it in 10 days, citing FCBA.
Key Takeaways: Quick Summary for Winning Your Dispute
- Act in 60 days: FCBA deadline for credit cards; 10 days provisional credit under Reg E.
