Dispute Dossier Builder

The Deadline Is the Boss

Every dispute has a clock, and the clock starts on the statement date — not the day you noticed the charge. For credit cards, the Fair Credit Billing Act (Regulation Z, 12 CFR 1026.13) gives you 60 calendar days from the statement date to send a written billing-error notice. For debit cards and checking accounts, Regulation E (12 CFR 1005.6 and 1005.11) uses the same 60-day statement-date window for billing errors, and a much shorter one for unauthorized transfers: report within 2 business days of noticing and liability is capped at $50; after that but within 60 days of the statement, the cap rises to $500.

The dossier computes your exact deadline from the statement date you enter and shows it on the cover page, alongside the rule that applies to your card type. If the window is closing, the deadline panel tells you plainly — and it also tells you that a passed deadline is not the end of the road: fraud claims and issuer goodwill policies can still recover money.

One Kit, Four Parts

Most issuers ask for the same things regardless of the law involved. The dossier bundles them into a single printable document:

• Case details — the charge date, amount, descriptor, and reason, plus a cross-reference when the descriptor matches our reviewed database, including the merchant's official support channel.
• Deadline — the FCBA or Reg E window, computed from your statement date, with the issuer's investigation obligations spelled out.
• The letter — a formal billing-error notice addressed to the disputes department. It cites the law, states what happened, and requests investigation and reversal. Copy it or print it.
• Evidence checklist — the receipt, statement page, cancellation confirmation, and correspondence that make the difference between a form-letter dismissal and a real investigation.

What Evidence Actually Matters

Disputes are won with documentation, not outrage. The strongest single exhibit is the statement page itself: it proves the descriptor, amount, and posting date. After that, issuers weigh receipts and order confirmations for "I never got it" claims, cancellation confirmations for "I cancelled but was charged" claims, and any emails or chat logs that show you asked the merchant first. The checklist marks each item you have gathered, and the printed dossier shows which boxes are checked — a quiet signal to the investigator that you came prepared.

What Not to Send

The first letter should contain the last four digits of the card or account, never the full number, and never your Social Security number. Issuers already have both on file; putting them in a letter that may be scanned, faxed, or photocopied adds risk without adding strength. Send only what the issuer requests, keep a copy of everything, and use the issuer's dispute portal if it accepts written notice there — it does under the law, and it creates a timestamped record.

Who the Rules Favor

The consumer-friendly parts of the law are real: for credit cards, you do not have to pay the disputed amount or its interest while the investigation runs, the issuer must acknowledge within 30 days, and it must resolve within two billing cycles (never more than 90 days). For debit, the bank must investigate within 10 business days and grant provisional credit if it takes longer. These are federal minimums — some issuers are faster. The worst thing you can do is wait past the statement-date window, which is exactly what the deadline panel exists to prevent.
