When you dispute a charge, banks investigate by analyzing transaction data (location, IP address, time), reviewing supporting evidence from you (receipts, communication with the merchant), and contacting the merchant for proof of authorization. They determine if the charge is fraudulent, a billing error, or a service failure, and generally, you have 60 days to report it.
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.
Is disputing a transaction bad? Not inherently, no. As a cardholder, you have a right to dispute a charge resulting from criminal fraud, or if the merchant committed an error. However, you should contact the merchant first before disputing the charge.
How to Fight
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.
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.
I am writing to dispute a charge of [$______] to my [credit or debit card] account on [date of the charge]. The charge is in error because [explain the problem briefly. For example, “the items weren't delivered,” “I was overcharged,” “I returned the items,” “I did not buy the items,” etc.].
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.
Banks investigate disputes by gathering transaction data, analyzing for fraud indicators like location/IP mismatches, contacting merchants for evidence (receipts, logs), reviewing customer-provided info, potentially issuing temporary credits, and using tech/AI to spot patterns, all while following strict timelines and regulations to ensure fairness and resolve the claim.
There is no specific statute describing chargeback fraud; instead, prosecutors may charge it under a range of criminal violations, any of which may result in substantial fines, jail or prison time, or mandatory restitution to the victim of the fraud.
The most frequent causes of denials fall into a few key categories.
In many instances, documents proving your position can be helpful for the credit bureaus, as well as jurors. If you choose to dispute by phone, you lose the opportunity to show that your position is correct. Phone calls may be used as a means of following up on a prior credit dispute.
Banks do not automatically accept every dispute as valid. The issuing bank will review the claim, gather information from the cardholder, and may request supporting documents—such as receipts, order confirmations, or copies of communication with the merchant.
Disputing a charge on your credit card will not negatively affect your credit standing, although the credit card company may add a statement to your credit report indicating that the account is currently in dispute.
However, if your dispute is denied, and those charges remain on your account, it can lead to a negative balance. This negative balance, if not promptly addressed, can be reported to credit bureaus, potentially damaging your credit score. This issue is where the Fair Credit Reporting Act (FCRA) becomes relevant.
Common Dispute Reasons
While many cases can be resolved quickly, some are more complex and can take up to 90 days.
The 2/3/4 rule is a guideline, primarily used by Bank of America, that limits how many new credit cards you can get: no more than 2 in 30 days, 3 in 12 months, and 4 in 24 months, helping to prevent over-application and manage hard inquiries on your credit report. While not universal, it's a useful benchmark for responsible card application, though other banks have different rules (like Chase's 5/24 rule).
Types of Evidence
How Often do Merchants Actually Win Chargebacks? According to the 2024 State of Chargebacks Report, merchants win on average about one-third of the disputes they face. Depending on the type of dispute, merchants win roughly 44% of “friendly fraud” cases, but their chances plummet to just 9% when true fraud is involved.
The most common method of dispute resolution is mediation, but it's not always the right choice for every case. Several other ways to resolve disputes are becoming increasingly popular over time.
