Banks decide on disputes by conducting an investigation based on evidence from both the cardholder and merchant, adhering to timelines set by card networks (often 30–90 days). The bank reviews documentation like receipts and communication, usually siding with the party providing stronger proof of a valid or invalid transaction.
When you initiate a dispute, banks review the transaction details, evaluate the evidence provided by both parties and decide whether to reverse the transaction or uphold it based on their findings. This process involves assessing the validity of the claim against the bank's policies and the rules of the card network.
Chances of winning a bank dispute (chargeback) are generally good for consumers with valid claims, often resulting in provisional credit and a win, but statistics show merchants win less than half their challenges; for consumers, having strong evidence like proof of non-delivery or unauthorized charges is key, while merchants must meticulously follow rules, provide detailed data (proof of delivery, communication), and act quickly to improve their odds, which are much better in "friendly fraud" (around 44%) than true fraud (around 9%).
After conducting an investigation, your card issuer may deny your dispute. For example, the issuer may not find evidence that the transaction you disputed was unauthorized. The issuer may deny the entire disputed amount or a part of it; either way, it should inform you in writing about the denial and how much you owe.
How to Fight
To win a civil case, you need evidence that proves each legal element of your claim by a preponderance of the evidence. This typically includes documents, witness testimony, physical or digital proof, and sometimes expert opinions.
The most frequent causes of denials fall into a few key categories.
If you have an issue with a charge on your credit card statement, you can turn to your issuer to resolve the matter. The bank is legally required to look into your dispute and give you a report about what it finds. However, consumers often don't get any concrete feedback about such investigations.
For buyers, the best dispute reason is arguably fraud or unauthorized activity. Cardholders who can produce compelling evidence showing that they did not approve a transaction are more likely to win a dispute than if it was initiated for another reason.
While many cases can be resolved quickly, some are more complex and can take up to 90 days.
To dispute a charge, you need strong evidence like receipts, invoices, contracts, delivery confirmations, and records of communication (emails, chats) with the merchant to show the charge was an error, fraudulent, or the product/service wasn't as described. Organizing these copies (not originals) and sending them with a formal dispute letter to your card issuer within 60 days helps prove your case, ideally using certified mail for proof of delivery, explains Consumer Advice | Federal Trade Commission.
Losing the chargeback means not only losing the sales revenue, but also the associated chargeback fees merchants typically must pay to cover the cost of the chargeback process.
Chargeback fraud, in law, can sometimes be considered a form of payment card fraud or wire fraud. So can chargeback fraud result in jail time? Technically, yes, but usually only in extreme circumstances where it's used to steal very high values or volumes of products and services.
The letter should say you're disputing errors and should include: your complete name and address; each bit of inaccurate information that you want fixed, and why; and copies (not originals) of documents that support your request. Many businesses want disputes sent to a particular address.
Dispute resolution refers to the processes used to settle disagreements between parties. There are three main types of dispute resolution: arbitration, mediation, and litigation.
Banks review transaction information, merchant details, and evidence submitted by both the cardholder and the merchant to determine which party is at fault. If the cardholder is at fault, the transaction remains on their credit or debit card statement.
These claims can result from misunderstandings, fraud, or attempts to bypass return policies. The cardholder can face consequences for chargeback abuse, including account freezes, losing one's bank account, damage to one's credit score, and even legal consequences.
Merchants won't know about a dispute until they receive a notification from their acquiring bank—the bank they use to settle payments.
Fraudulent Transactions: One of the most common reasons for a chargeback is fraud. A customer might notice charges on their credit card statement for purchases they did not authorize. Upon investigation, they discover their credit card information was stolen and contact their bank to file chargebacks.
