Chase publishes one number — typically 60 days from the statement — but your dispute actually runs on up to three clocks, and credit and debit follow different federal laws. Start with the Chase dispute navigator to get your exact deadline and filing plan, then use this guide for the full playbook.
On a Chase credit card, two clocks run in parallel and they are not the same thing:
The trap: the online report starts Chase's process, but the written letter is what preserves your federal rights. For billing errors — wrong amounts, double charges, goods never received, subscriptions that kept billing — send both. Certified mail with return receipt, so you can prove when Chase received it.
Two more FCBA facts from Chase's own page: your fraud liability is capped at $50 (most issuers offer zero-liability protection on top), and while a dispute runs you do not have to pay the disputed charge — but you must keep paying at least the minimum payment, or a missed payment can damage your credit. Disputes themselves do not hurt your credit score, though the issuer may note the account is in dispute until the case closes.
A Chase debit card dispute runs on federal law — Regulation E (12 CFR 1005.6 and 1005.11) — which works differently from credit cards:
One honest boundary: Regulation E's error-resolution machinery covers unauthorized transfers and bank errors, not merchant-quality disputes. If your debit complaint is "the item was wrong" rather than "I never authorized this," file it the same way — but know the card-network dispute rules do the work, and Chase's own 60-day guidance is the clock to beat.
Here is where most Chase dispute guides stop being honest. Three different numbers come from three different rulebooks:
The 120-day window is issuer-facing: you cannot invoke it directly — you file through Chase, and Chase decides what to file. But it is real, and it is why a dispute filed through Chase after day 60 can still reach the merchant. If you are past Chase's 60 days but inside ~120 days of the transaction, call Chase and ask specifically whether your case can still be filed as a network dispute — and put the request in writing. For the full clock-by-clock breakdown, see our Chase dispute time limit guide, and run your dates through the navigator.
Chase offers three filing routes — all from Chase's own pages:
Chase's own guidance says to contact the merchant first for billing problems — do it, and keep the messages. It also asks you to gather receipts, photos, and any merchant communication before filing, to show a good-faith effort to resolve it.
Chase's dispute form asks follow-up questions about what went wrong; answer them exactly. Beyond that, the evidence that decides each case type is consistent:
Most guides promise a provisional-credit date for credit cards. Chase does not publish one — its own wording is that "timing of credits and response times will differ based on your specific dispute." Many issuers do issue a temporary credit early in an investigation, but treat any credit as exactly that: temporary. If Chase rules against you, it is reversed and you owe the amount.
For unauthorized debit transfers, the rule is federal and specific: provisional credit within 10 business days when the investigation runs longer, full use of the money during the investigation. If 10 business days pass with no credit and no decision, ask Chase for it in writing.
A denial is not the end. Use this ladder in order:
Get your exact deadline first: run your statement and transaction dates through the Chase dispute navigator — it maps every clock that applies to your case, labeled by who sets it, and builds your filing plan.
Chase's own published guidance says you typically have 60 days from the statement date that reflects the charge to dispute it. Separately, the FCBA requires a written billing-error notice within 60 days of when the first bill with the error was sent — the written letter, not just the online report, is what preserves your federal rights.
Report it within 60 days after the statement was sent under Regulation E — but report fraud immediately regardless. File in the Chase app (tap the charge, then "Report a problem") or call 1-800-935-9935, opt. 8. If the investigation runs past 10 business days, Chase must provisionally credit your account while it continues.
The 120-day figure is a card-network norm, not Chase-published. Visa/Mastercard chargeback frameworks let the issuer file most dispute categories up to about 120 days from the transaction processing date. Chase's own customer guidance stays at typically 60 days from the statement — but a dispute filed through Chase after day 60 can still reach the merchant through the network window.
Chase does not publish a fixed provisional-credit schedule for credit-card disputes — its own wording is that timing of credits and response times will differ based on your specific dispute. For unauthorized debit transfers, Regulation E requires provisional credit within 10 business days when the investigation runs longer. Treat any early credit as temporary.
Ask Chase to reconsider in writing with new evidence; for credit-card billing errors still inside 60 days of the first bill showing the error, send the FCBA written billing-error notice by certified mail, which forces a written acknowledgment within 30 days; then file a complaint with the CFPB at consumerfinance.gov/complaint, which Chase must answer.
