How credit card disputes work and what you need to prove
A credit card dispute is a formal challenge you file with your card issuer when you believe a charge is wrong. The issuer investigates by requesting documentation from both you and the merchant, then decides whether to reverse the charge or uphold it. You do not need a lawyer, and you do not pay a fee — the process is built into your cardholder agreement.
The outcome depends almost entirely on what evidence you can show. If you dispute a charge as unauthorized, you need proof you did not make it or authorize it. If you dispute it as a billing error, you need proof the amount was wrong or the charge appeared twice. If you dispute it as a service not received, you need proof you paid but the merchant did not deliver. The issuer's job is to weigh your evidence against the merchant's response, not to take your word.
Most disputes are resolved in your favor if you have clear documentation. The issuer's investigation typically takes 30 to 90 days, though they may issue a provisional credit within 10 business days while they investigate. During that time, the charge remains on your account but marked as disputed.
Key Takeaways
- File your dispute in writing through your card issuer's website or by mail within 60 days of the charge appearing on your statement, because verbal disputes are not legally protected.
- Gather all evidence before filing: receipts, emails, order confirmations, shipping tracking, or proof the merchant refused to refund you.
- State the specific reason — unauthorized charge, billing error, duplicate charge, or service not received — because the issuer investigates each type differently.
- The issuer must respond within 30 days and resolve the dispute within 90 days; if they miss the important date without resolving it, you win by default.
- If the issuer rules against you, you can escalate by requesting they reconsider, but only if you have new evidence they did not see the first time.
The 60-day window and how to file your dispute
You have 60 days from the date the charge appears on your statement to file a dispute. This important date is federal law under the Fair Credit Billing Act, and it applies to all card issuers. If you miss it, you lose the right to dispute that charge entirely, so mark your statement date on a calendar if you suspect a problem.
File in writing, not by phone. Call your issuer first to understand what happened and to document that you tried to resolve it directly, but then follow up with a written dispute through your card's website or by certified mail to the address listed on your statement. Written disputes create a record the issuer must acknowledge and investigate. Verbal disputes are not legally protected and can be denied without explanation.
When you file, include your account number, the transaction date, the merchant name, the amount, and a clear statement of why you are disputing it. Attach copies of any supporting documents — never send originals. Keep copies of everything you send and note the date you sent it.
What evidence wins disputes and what does not
The strongest evidence is a paper trail that shows what you paid for and what you received. For an unauthorized charge, save any proof you were not the one who made it: a police report if your card was stolen, a statement from your bank showing the card was compromised, or evidence you were in a different location when the charge occurred. For a duplicate charge, show both transactions on your statement and proof from the merchant that they only shipped one order.
For a service not received, gather emails from the merchant acknowledging the problem, tracking information showing the package was never delivered, or a refund request you sent that they ignored. Screenshots of your order confirmation and the merchant's website are useful but not as strong as official documentation. If the merchant promised a refund and never sent it, save those emails.
Weak evidence includes your own notes about what happened, a vague memory of the transaction, or a general complaint that the product was not what you expected. Disputes over product quality or whether something was "worth the price" are almost never won, because those are disagreements about the merchant's service, not billing errors. The issuer will side with the merchant unless you can show the item never arrived or was materially different from what was advertised.
What the issuer does during the investigation
Once you file, the issuer sends your dispute to the merchant and asks them to respond within a set timeframe, usually 7 to 10 days. The merchant can accept the dispute, deny it, or provide evidence that the charge was legitimate. If they do not respond, the issuer often rules in your favor by default.
The issuer compares what you submitted against what the merchant submitted. They look for proof of delivery, signed receipts, order confirmations, and any communication between you and the merchant. If the merchant provides a signed receipt or delivery confirmation, that is strong evidence against you — it shows you received the item or service. If the merchant cannot produce evidence, the issuer is more likely to reverse the charge.
The issuer must send you a written response within 30 days stating whether they are investigating further or have made a decision. If they decide in your favor, the charge is reversed and any interest or fees related to it are removed. If they decide against you, they explain why and tell you how to escalate if you have new evidence.
Provisional credits and when you get your money back
Many issuers issue a provisional credit within 10 business days while they investigate. This credit is temporary — if the issuer later rules against you, they will remove it from your account. The provisional credit does not mean you have won; it means the issuer is giving you the benefit of the doubt while they gather information.
If the issuer rules in your favor, the provisional credit becomes permanent and you keep the money. If they rule against you, the provisional credit is reversed and the charge returns to your account. You will owe the full amount again, plus any interest that accrued while the charge was disputed.
The full investigation takes up to 90 days. If the issuer does not resolve the dispute within 90 days, you win by default and the charge is permanently reversed. This is rare but happens when the merchant does not respond or the issuer falls behind on their investigation.
How to respond if the issuer rules against you
If the issuer decides the charge was legitimate, you have the right to request reconsideration, but only if you have new evidence you did not submit the first time. Do not straightforward resubmit the same documents and ask them to reconsider — they will deny it again. Instead, gather additional proof: a new email from the merchant, a shipping update you did not have before, or a statement from a witness.
Send your new evidence in writing within 10 days of receiving the issuer's decision. Explain what the new evidence shows and why it changes the outcome. The issuer will review it and respond again, usually within 30 days. If they still rule against you, that decision is final and you cannot dispute the same charge again.
At that point, your options are to contact the merchant directly and ask for a refund, file a complaint with your state's attorney general or the Consumer Financial Protection Bureau if you believe the issuer mishandled the investigation, or pursue the merchant in small claims court if the amount is large enough to justify the effort.
Common reasons disputes are denied and how to avoid them
The most common reason a dispute is denied is a signed receipt or delivery confirmation. If the merchant can show you signed for the package or that it was delivered to your address, the issuer will assume you received it. If you did receive it but it was damaged or defective, that is a quality complaint, not a billing error, and the issuer will not reverse the charge.
Disputes are also denied when you authorized the charge but later changed your mind. If you ordered something, received it, and then decided you did not want it, that is a return issue, not a dispute. The issuer will not reverse the charge unless the merchant refused to process a legitimate return.
Disputes fail when you wait too long to file. If more than 60 days pass from the statement date, you lose the right to dispute, even if the charge was fraudulent. Disputes also fail when you do not provide enough detail about what went wrong. A one-sentence complaint like "I did not authorize this" is weaker than a detailed explanation with supporting documents.
Frequently Asked Questions
Can I dispute a charge if I authorized it but the merchant never delivered?
Yes. An authorized charge that results in no delivery is a valid dispute. You need proof you paid and proof the merchant did not deliver — tracking information showing the package never arrived, emails from the merchant saying they cannot fulfill the order, or a refund request you sent that they ignored. The merchant's failure to deliver is a breach of the transaction, not a billing error.
What happens to my credit score while a dispute is pending?
The disputed charge remains on your account but is marked as disputed, so it does not count as a missed payment or default. Your credit score is not affected by the dispute itself. If the issuer rules against you and the charge stays on your account, it continues to count toward your balance and credit utilization, which can affect your score.
Can the merchant sue me if I dispute a charge?
A merchant cannot sue you for disputing a charge through your card issuer. The dispute process is a legal protection built into your cardholder agreement. The merchant's recourse is to provide evidence to the issuer that the charge was legitimate. If the issuer rules in their favor, the charge stands, but they cannot pursue you separately for disputing it.
Do I have to pay the disputed charge while the investigation is happening?
No. If the issuer issues a provisional credit, you do not owe that amount while they investigate. If they do not issue a provisional credit, you still do not have to pay the disputed portion — the issuer cannot report you as delinquent on a charge you have formally disputed. However, if the issuer later rules against you, the charge returns and you owe it in full, plus any interest that accrued.
What if the merchant goes out of business after I dispute?
The merchant's business status does not affect the dispute. The issuer will attempt to contact them, but if they are out of business and do not respond, the issuer often rules in your favor by default. If the merchant does respond with evidence before closing, the issuer will use that evidence to make a decision. A closed business does not automatically mean you win, but it makes it harder for the merchant to defend the charge.
