Amex Dispute Timeline: How Long You Have to File
You have 120 days from the transaction date to dispute an American Express charge. Here is when you get longer, how to file, and what happens next.
You spot a charge on your American Express card that you do not know. Your first question is how much time you have. The answer is a set number of days, and the clock starts running from a fixed point. This page walks through the whole timeline, from your side and the shop's side, using Amex's own words.
How long you have to dispute an Amex charge
The number to hold in your head is 120. An American Express cardholder, not the merchant, has up to 120 days from the transaction date to dispute a charge.
Two parts of that sentence matter. First, the clock starts at the transaction date, not at the date the charge posted or the date you first noticed it. Second, the 120 days belong to you, the cardholder. The shop does not get to use them.
So if a charge went through on a date you can pin down, count forward from that day. If you are close to the line, file now and sort the details later. A dispute you start on day 100 is safe. One you plan to start next month may not be.
When you may have longer than 120 days
The 120-day window is the general rule.
An American Express cardholder can have longer to dispute a charge for goods not received, returns or cancellations.
If your case falls in one of those three groups, do not assume the 120 days have passed you by. Ask Amex about your case when you file.
How to start a dispute with American Express
Filing is not a form you fill out by hand. Amex's help center says you can dispute a charge by selecting the transaction and clicking "Dispute this Charge".
So the path is short. Find the charge in your account, select it, and click the button. From there Amex walks you through the rest.
Before you click, it pays to know what counts. American Express's guide says Card Members can dispute a charge for lots of reasons.
What happens after you file: Amex works with you first
Many people assume a dispute works like a court case. You file, and the shop gets served papers the same day. Amex runs it in a different order.
American Express's guide says it works directly with the Card Member and tries to resolve the case before reaching out to the merchant.
So the first conversation is between you and Amex. The shop may not hear anything at all. Some cases end at this stage, if the charge turns out to be one you forgot, or one a family member made. For a fuller walk through this part, see our page on the amex charge dispute process.
The merchant's side: Inquiries, Chargebacks and the 20-day window
If Amex cannot close the case with you alone, the shop enters the picture. American Express's guide says a merchant will either receive an Inquiry or a Chargeback if more information is needed.
An Inquiry is the softer of the two. Amex asks the shop for its side of the story. A Chargeback takes the money back while the question is open.
Either way, the shop is now on a clock. A merchant has 20 days to respond to an Inquiry or Chargeback from American Express with supporting documents. And the starting gun is clear. The merchant's 20 days to respond start once American Express contacts it with an Inquiry or a Chargeback.
To see the full process from the shop's point of view, read our page on the amex chargeback flow.
If the merchant misses the deadline, or answers it well
The 20-day window has teeth on both ends.
If the shop stays silent, the case goes against it. American Express's guide says the merchant's account will be debited if the merchant does not reply in time or with the requested documentation. So a shop that misses the window, or sends back nothing useful, pays for the charge.
If the shop answers well, the story can flip. American Express's guide says it will undo the Chargeback if the merchant's reply addresses the dispute successfully and on time. So a win at this stage is not always final. A chargeback that went your way can come back if the shop makes a strong, on-time case.
That is why your own records matter. Keep the order confirmation, the emails, the cancellation notice, whatever you have. If the shop answers with proof, your proof is what answers back.

One last thought on speed. The 120-day window feels long on the day you spot the charge. It feels short in week fifteen. File early, keep your records, and let the timeline work for you instead of against you.
