What Does a Dispute Mean in Banking: Deadlines, Filing, and Liability

In banking, a dispute is a formal challenge you file with your bank or card issuer to contest a charge on your account. Two federal laws set the ground rules: the Fair Credit Billing Act covers credit card billing errors, and Regulation E covers debit cards and other electronic transfers. Both let you contest unauthorized charges, billing mistakes, and charges for goods you never received. The deadlines, the dollar you might be on the hook for, and the way you have to file all depend on whether the charge hit a credit card or a checking account.

What You Can Dispute

Federal law defines the categories narrowly. For credit cards, the Fair Credit Billing Act recognizes these billing errors:

Unauthorized charges: someone used your card without permission.
Wrong amounts or dates: the merchant billed more than the agreed price, or the transaction date is recorded incorrectly.
Goods or services not delivered or not accepted: you were charged for something that never arrived or that you refused.
Math or accounting mistakes on your statement.

These categories come straight from the statute and apply to any open-end credit account, store cards included.¹

For debit cards and bank accounts, Regulation E covers a parallel list: unauthorized electronic fund transfers, incorrect transfers to or from your account, duplicate charges, and transfers missing from your periodic statement.² A subscription that keeps billing after you canceled qualifies, and so does any transfer you never authorized.

You do not have to contact the merchant first for billing errors like undelivered goods on a credit card. You can go straight to your card issuer.³

Quality-of-Goods Disputes on a Credit Card

If a product arrives but is defective, significantly different from what was advertised, or the service was poorly performed, that is not a billing error. It is a quality dispute, and you can hold your card issuer responsible for the merchant’s failure only if three conditions are met:

You made a good-faith effort to resolve the problem with the merchant first.
The transaction was more than $50.
The purchase was made in your home state or within 100 miles of your billing address.

The geographic and dollar limits fall away when the card issuer and the merchant are the same company, are under common ownership, or when you bought the item through a mail or online solicitation the card issuer participated in. The amount you can dispute is capped at whatever balance is left on the purchase when you notify the issuer. Pay it off first, and you have nothing left to dispute.⁴

Deadlines and What You Could Owe

The clock starts when your statement is sent. Miss the window and you can lose the right to dispute at all, or worse, remain liable for unauthorized charges that keep coming.

Credit Cards

You have 60 days from the date the issuer sent your statement to submit a written billing error notice. Send it to the address the issuer designated for billing inquiries, not the payment address. Include your name, account number, the amount you believe is wrong, and why.¹ Miss the 60 days and the issuer has no legal duty to investigate.

For unauthorized charges, federal law caps your personal liability at $50 no matter how much the thief spent, and once you report the card lost or stolen you owe nothing for charges after the report.⁵ Most major card networks add zero-liability policies on top, but $50 is the federal floor.

Debit Cards

Debit exposure depends entirely on how fast you report. Federal law creates three tiers:

Within 2 business days of learning the card was lost or stolen: liability capped at $50.
After 2 business days but within 60 days of your statement being sent: liability rises to $500.
After 60 days from the statement date: unlimited liability for unauthorized transfers that occur after the 60-day mark.

The unlimited tier applies to transfers the bank can show it could have stopped had you reported sooner.⁶ Because debit charges pull straight from your checking account, a delay can drain the money you need for rent and bills. Check statements every month.

How to File

Before you contact the bank, pull together the transaction date, merchant name, exact dollar amount, and any supporting evidence: receipts, shipping confirmations, screenshots of cancellation requests, email exchanges with the merchant.

Credit Cards

Federal law requires a written notice, received at the billing-inquiries address within 60 days of the statement date.¹ The address is on your monthly statement or the issuer’s website. A note on your payment stub does not count; the statute excludes that. Most issuers accept disputes through their online portal or app, which satisfies the written notice requirement, but confirm with your issuer before relying on a digital submission alone.

Debit Cards and Bank Accounts

Regulation E is more forgiving. You can report an error orally or in writing.² Calling the number on the back of the card is enough to start the process. The bank can require a written follow-up within 10 business days of your call. If you skip that follow-up when asked, the bank can stop the investigation and pull back any provisional credit it applied.

Whichever route you use, ask for a reference or claim number. It ties your future calls and letters to the same file and marks the official start of the investigation.

What the Bank Has to Do Next

Once you file, the bank runs a regulated investigation on firm deadlines.

For debit and electronic transfer disputes, the bank has 10 business days to resolve the investigation. It can extend to 45 days, but only if it provisionally credits your account within those first 10 business days and gives you full use of the funds during the investigation.⁷ The window stretches to 90 days for point-of-sale debit transactions, transfers from a new account (opened within the past 30 days), or foreign-initiated transfers.² If the bank ultimately decides no error occurred, it can reverse the provisional credit, but it has to notify you first and explain why.

For credit cards, the issuer must acknowledge your written notice within 30 days of receiving it, unless it resolves the dispute entirely within that same 30-day window.³ The issuer then has two full billing cycles, and never more than 90 days from receipt of your notice, to finish the investigation and either correct the error or explain why the charge was accurate.¹

Protections While the Investigation Is Open

For credit cards, two protections matter most. You do not have to pay the disputed amount or the finance charges tied to it while the investigation is open. If you use autopay, the issuer must stop deducting the disputed portion as long as you tell them at least three business days before the next scheduled payment. The issuer also cannot report the disputed amount as delinquent or make any adverse credit report about it during the investigation. Both rules sit in Regulation Z’s billing error resolution provisions.³

For debit card disputes, the provisional credit plays the same role: it puts money back in your account so you can cover expenses while the bank looks into it. If autopay is pulling the disputed amount, contact the bank separately to stop those payments until things are resolved.

If the Bank Denies Your Dispute

A denial is not the end. When a credit card issuer says no billing error occurred, it must explain why and, if you ask, send you copies of the documents it relied on.¹ Reviewing those documents often shows weak spots you can push back on. For debit disputes, the bank’s findings come in writing, and you can request more detail about how it reached its decision.

If you believe the bank mishandled the dispute, file a complaint with the Consumer Financial Protection Bureau. The CFPB forwards it to the bank, which generally responds within 15 days.⁸ A complaint does not guarantee a different outcome, but it puts regulatory pressure on the bank and creates a formal record. If your bank is FDIC-supervised, you can also complain directly to the FDIC’s Consumer Response Unit.⁹

Small claims court is the last option for a concrete dollar amount you can’t recover any other way. You generally don’t need a lawyer, and the process is built for people representing themselves. Send a final written demand to the bank first, explaining the amount and the legal basis. That letter alone sometimes prompts a settlement.

Business Accounts Are Not Covered

Everything above applies to consumer accounts. If you hold a business checking or debit account, the Electronic Fund Transfer Act and Regulation E generally do not apply to you. Business accounts fall under the Uniform Commercial Code as each state has adopted it, which gives you a framework for resolving payment disputes but not the same provisional credit rules, liability caps, or investigation timelines. Your rights depend on your deposit agreement and your state’s UCC, and reporting deadlines in commercial banking contracts are often shorter and less forgiving. Read the agreement, and report anything unauthorized fast.
