Quick Summary: Key Takeaways
- Top Evidence Types: Credit card statements (screenshots), receipts/invoices, affidavits, witness statements, transaction timelines, and digital forensics for complex cases.
- 60-Day Dispute Window: FTC's Fair Credit Billing Act (FCBA) requires disputes within 60 days of the statement date showing the charge; max liability $50 (often $0 with modern cards).
- 90-Day Issuer Investigation: Banks must acknowledge in 30 days and resolve in 90 days (Bankrate/CFPB).
- Merchant Win Rate: Only 32% average for representment (Chargebacks911 data), emphasizing strong, organized evidence.
- Retention Rules: Keep records 25 months (CFPB §1026.25, §1002.12) or per FFIEC BSA/AML for fraud probes.
What Counts as Strong Evidence for Credit Card Charge Disputes?
Strong evidence directly proves the charge was unauthorized, erroneous, or fraudulent. Per FTC guidelines, your liability is capped at $50 under FCBA for unauthorized use--if reported promptly. Banks and networks like Visa/Mastercard prioritize clear, verifiable proof over verbal claims. Start with basics like statements and receipts, then layer advanced items.
Key stats: Consumers win ~80-90% of valid fraud disputes with solid evidence; merchants struggle at 32% without it.
Types of Evidence: From Basic to Advanced
| Evidence Type | Best For | Examples | Strength |
|---|---|---|---|
| Basic: Statements & Screenshots | All disputes | High-res screenshots of charges on statements, transaction details (date, merchant, amount) | High--immediate visual proof; FTC recommends keeping receipts/statements. |
| Receipts & Invoices | Billing errors, non-delivery | Physical/digital receipts, packing slips | Essential; proves what you did/didn't receive. |
| Witness Statements | Shared accounts, in-person fraud | Signed statements from family/friends confirming non-authorization | Medium--bolsters affidavits. |
| Timelines | Fraud sequences | Chronological docs (e.g., "Charge on 1/15; reported 1/20") | Critical; CFTC advises building while fresh. |
| Advanced: Affidavits & Forensics | Scams, CNP fraud | Sworn affidavits; IP logs, device forensics | Game-changer for disputes; irrefutable in court. |
For fraud vs. billing errors: Fraud needs proof of non-authorization (affidavit); errors need delivery mismatches (receipts).
Legal Requirements and Guidelines for Evidence in 2026
In 2026, FTC/CFPB rules protect consumers, while Visa/Mastercard enforce network standards. FCBA mandates 60-day disputes for billing errors; fraud has no strict limit but act fast. Retention: 25 months for TILA disclosures (CFPB §1026.25); 5 years for BSA records (FFIEC).
Visa/MC: 30-day issuer reviews; merchants respond in 7-10 days (Signifyd).
FTC and CFPB Rules vs. Card Network Policies
| Aspect | FTC/CFPB (Consumers) | Visa/Mastercard (Merchants/Networks) |
|---|---|---|
| Dispute Timeline | 60 days from statement | Issuers: 30 days review; Merchants: 7-10/30 days response |
| Investigation | 30-day ack + 90-day resolution | 7-14 days merchant reply (Helcim) |
| Liability | $50 max ($0 common) | Merchants bear CNP fraud risk |
| Evidence | Statements, receipts, affidavits | Full transaction data, customer comms |
Contradictions: FTC's 10-day variable payment notice vs. banks' 90-day probes--file CFPB complaints if delayed.
