What Does It Mean to Dispute a Purchase? Process and Timelines

To dispute a purchase means asking your bank or card issuer to formally reverse a charge on your account because the transaction was unauthorized, incorrect, or involved goods or services you never received. It’s not the same as asking a merchant for a refund. A dispute is a structured process governed by federal law and card network rules, and it pulls the money back from the merchant’s bank through the payment network. Two federal statutes set the floor for your rights: the Fair Credit Billing Act for credit cards, and the Electronic Fund Transfer Act for debit cards. The protections under each are not equal, and that gap matters before you file.

What Actually Happens When You Dispute a Charge

When you file a dispute, your bank initiates what the payments industry calls a chargeback. Funds are pulled from the merchant’s bank account, routed through the card network (Visa, Mastercard, and the rest), and returned to you. Your bank is the issuing bank. The merchant’s bank is the acquiring bank. The card network sits between them and enforces a standardized set of rules, reason codes, and deadlines that both sides must follow.

The system exists because you have no direct financial relationship with the merchant. Your bank extended you credit or gave you access to a deposit account. The merchant’s bank agreed to accept card payments. When something goes wrong, the network’s rules decide who eats the loss. Federal law sits above those rules and sets the minimum protections you’re entitled to as a consumer.

Valid Reasons to Dispute

A dispute isn’t a way to get out of a purchase you regret. Issuers require you to specify a reason when you file, and the claim needs to be backed by evidence. Four categories cover almost everything.

Unauthorized Transactions

These are the clearest cases. Someone used your card number for an online purchase, took your physical card, or gained access to your account and made transactions you didn’t authorize. You’ll need to confirm you don’t recognize the merchant and didn’t participate in the transaction.

Billing and Processing Errors

Being charged twice for the same purchase, being billed a different amount than you agreed to, or a refund the merchant promised that never posted. Technical failures fall here too, such as an authorization that expired before the charge settled. These resolve quickly when you can produce a receipt or duplicate transaction records.

Goods or Services Not Delivered or Defective

You paid for something that never arrived, or what arrived was fundamentally different from what the merchant described. These carry the highest evidence burden because they come down to your account versus the merchant’s. Keep shipping confirmations, product photos, listing screenshots, and every message where the merchant acknowledged the problem. The item has to be genuinely unusable or materially different from what was advertised. Buyer’s remorse is not grounds.

Subscription and Recurring Charges

Recurring billing problems are a fast-growing category of disputes. Under the Restore Online Shoppers’ Confidence Act, any business that charges you through a subscription or automatic renewal has to clearly disclose all terms before collecting your billing information, get your express informed consent before charging, and give you a simple way to cancel.¹ The FTC’s click-to-cancel rule reinforces this by requiring cancellation to be at least as easy as signing up.² If a company keeps charging after you cancelled, enrolled you without clear consent, made cancellation unreasonably difficult, or billed you before a free trial ended, those are legitimate grounds. Document every cancellation attempt before you file.

Credit Card Disputes vs. Debit Card Disputes

This is where most people get tripped up. The liability rules for credit and debit cards are not close to equal.

Credit Cards

Credit card disputes fall under the Fair Credit Billing Act, implemented through Regulation Z.³ Your maximum liability for unauthorized use is $50, and only if the issuer meets several conditions, including giving you adequate notice of potential liability and a way to report loss or theft.⁴ In practice, every major card network runs a zero-liability policy that erases even the $50 for most unauthorized transactions.⁵

For billing errors like double charges, wrong amounts, or undelivered goods, you must send written notice to your issuer within 60 days of the statement date reflecting the error.⁶ The notice has to identify your account, describe the error, and explain why it’s wrong. Most issuers now take disputes online or by phone, but the statute defines a billing error notice as written. If you want ironclad protection under the FCBA, follow up in writing.

Debit Cards

Debit card disputes are covered by the Electronic Fund Transfer Act, implemented through Regulation E.⁷ The liability structure is tiered, and speed matters:

Report within 2 business days: liability caps at $50 or the unauthorized amount before you notified the bank, whichever is less.
Report after 2 business days but within 60 days of the statement: liability jumps to $500 or the total unauthorized transfers in that window, whichever is less.
Report after 60 days: you can lose everything. The bank has no obligation to reimburse unauthorized transfers after the 60-day window closed if it can show those transfers wouldn’t have happened had you reported on time.

Those tiers come straight from the statute and Regulation E’s implementing rules.⁸⁹ If your debit card is compromised, report it immediately. Waiting even a few days can multiply your exposure. Visa’s zero-liability policy also covers debit transactions processed through its network, but that’s a voluntary network policy, not a federal guarantee, and it comes with conditions including account good standing and timely reporting.⁵

How to File

Start with the merchant. Call, email, or use their online support and ask for a refund or correction. This isn’t just courtesy. Your bank will ask whether you tried to resolve it directly, and some card network rules require it. Save everything: dates, names, chat screenshots, email threads.

If the merchant refuses, stops responding, or has disappeared, contact your card issuer. Most banks let you open a dispute through their app, website, or by phone. You’ll need the merchant name, transaction date, dollar amount, and a description of the problem.

For credit card billing errors, the FCBA’s 60-day clock starts when the issuer transmits the statement containing the error, not when you notice it.⁶ If you file online or by phone, also send written notice to the address your issuer designates for billing disputes, which is often different from the payment address. For debit cards under Regulation E, notify your bank as soon as you can. The 2-business-day window for limiting liability to $50 is painfully short.⁹

Gather evidence before you file. The strongest disputes include receipts, order confirmations, delivery tracking, photos of defective goods, and screenshots of merchant communications. Weak evidence is the single most common reason disputes get denied.

What Happens After You File

Provisional Credit and Timelines

For debit disputes, your bank must either finish investigating within 10 business days or provisionally credit your account for the disputed amount and take up to 45 days to complete the investigation.¹⁰ Provisional credit gives you temporary access to the funds while the case works through. For new accounts (within 30 days of the first deposit), the bank gets 20 business days instead of 10. For point-of-sale debit transactions and international transfers, the investigation window stretches to 90 days.

Credit card disputes work differently. Under the FCBA, the issuer must acknowledge your billing error notice within 30 days and resolve the investigation within two complete billing cycles, up to a maximum of 90 days.¹¹ There’s no explicit provisional credit mandate for credit cards, but most issuers remove the disputed amount from your balance during the investigation as a practical matter.

The Investigation and Your Credit Report

Your bank presents the dispute to the merchant’s bank, which notifies the merchant. The merchant has a limited window to respond with evidence defending the charge. If the merchant misses the deadline or the evidence is insufficient, the chargeback stands and the credit becomes permanent. If the merchant produces compelling evidence such as signed delivery receipts, usage logs, or proof of authorization, the bank may deny your dispute. In that case the provisional credit is reversed and the charge returns to your account. Your bank has to explain the denial in writing and, for credit card disputes, provide copies of the merchant’s evidence if you ask.¹²

For credit card disputes, federal law prohibits your issuer from reporting the disputed amount as delinquent while the investigation is pending. The creditor can note the amount is “in dispute” on your report, but cannot threaten your credit over the unpaid disputed balance or report you as late.¹³ Your issuer also cannot close or restrict your account solely because you disputed a charge.¹¹ These protections last until the investigation concludes and you’ve been given at least 10 days after the resolution to pay any amount found to be valid.

If Your Dispute Is Denied

A denial isn’t necessarily the end. Within the card network process, your bank can escalate to pre-arbitration, which gives the merchant another chance to accept the chargeback or defend it further. If the merchant refuses, the case can move to network arbitration, where the card network reviews the evidence and issues a final ruling. Those stages are handled between the banks. Your job is to push your issuer to keep pursuing the case and to hand over any additional evidence they request.

Outside the network, you can file a complaint with the Consumer Financial Protection Bureau if you believe your bank mishandled the investigation. The CFPB forwards your complaint to the company, which usually responds within 15 days. You’ll need a clear description of the problem, the key dates and amounts, and supporting documents.¹⁴ A CFPB complaint won’t reverse the chargeback on its own, but the regulatory pressure often produces results that phone calls to customer service didn’t. Small claims court is another route for pursuing the merchant directly, though most major credit card agreements route disputes into binding arbitration instead of court, so check your cardholder agreement first.

What Counts as an Improper Dispute

Disputing a charge for a purchase you actually made and received as described is called friendly fraud. Banks track dispute patterns closely, and accounts that generate frequent chargebacks get flagged fast. Your bank can freeze your card, cut your credit limit, ask for extra documentation on ordinary transactions, or close your account entirely. Some institutions start reviewing accounts after only two or three disputes in a short period, and those reviews aren’t reserved for proven fraud; a pattern of costly disputes is enough.

Beyond the account consequences, deliberately filing a false chargeback can expose you to criminal liability. There’s no standalone federal statute for “chargeback fraud,” but prosecutors can bring charges under existing laws covering wire fraud, bank fraud, mail fraud, or theft, depending on how the transaction was made and the dollar amount involved. The merchant can also pursue civil claims for the disputed amount plus damages. None of this touches good-faith disputes where you genuinely believe a charge was wrong. It applies to filing a chargeback to get free merchandise or services you used and enjoyed, which banks and law enforcement treat seriously.
