How to Dispute an Unauthorized Credit Card Charge in California
How long do I have to dispute a credit card charge under federal law?
Under the federal Fair Credit Billing Act, you have 60 days from the date your billing statement containing the disputed charge was mailed or made available to you. That window starts from the statement date, not the date you noticed the error. Missing the 60-day deadline means you lose the law's formal dispute protections.
What happens after I file a credit card dispute?
After you submit a written dispute, your card issuer is required under the Fair Credit Billing Act to acknowledge it within 30 days and resolve it within two billing cycles, capped at 90 days. During that time, the issuer cannot report the disputed amount as delinquent to credit bureaus or attempt to collect on it while the investigation is pending.
Where do I report a credit card billing dispute that my bank won't resolve?
California cardholders whose issuers deny or ignore a legitimate billing dispute can file a complaint with the Consumer Financial Protection Bureau at consumerfinance.gov/complaint. You can also file a complaint with the California Attorney General's office at oag.ca.gov/consumers, which enforces state consumer protection law against financial companies operating in California.
Does a credit card dispute hurt my credit score?
Filing a credit card dispute itself does not directly damage your credit score. Under the Fair Credit Billing Act, an issuer cannot report a disputed amount as delinquent while a legitimate dispute is under investigation. However, if a dispute is resolved against you and the balance goes unpaid, that unpaid balance can eventually be reported and affect your credit.
What's the difference between a credit card dispute and a chargeback?
These terms are often used interchangeably by consumers, but technically a chargeback is what happens on the card network's side after your issuer rules in your favor: the funds are pulled back from the merchant. A dispute is the formal process you initiate with your card issuer under the Fair Credit Billing Act. Filing the dispute is your step; the chargeback, if warranted, is your issuer's action against the merchant.
An unfamiliar charge on your credit card statement - whether it's a merchant billing error, a subscription you never agreed to, or outright fraud - is something most California cardholders will encounter at some point. Federal law gives you the right to dispute it, and California's own consumer protections layer additional muscle on top of that. Knowing the process, and how quickly you need to move, can mean the difference between getting your money back and absorbing a loss that should never have been yours.

What Counts as a Disputable Charge
The federal Fair Credit Billing Act (FCBA) covers unauthorized charges (someone used your card without permission), charges for goods or services you didn't receive or that were significantly different from what was advertised, billing errors like duplicate charges or wrong amounts, and charges by merchants who didn't honor a return or cancellation. The FCBA does not cover disputes over the quality of a service you did receive and agreed to pay for - those are a different conversation with the merchant directly.
California's Rosenthal Fair Debt Collection Practices Act and the state's Unfair Competition Law can come into play if a card issuer or debt collector engages in deceptive or abusive practices around a disputed balance, but for the core dispute process, federal law sets the framework every California cardholder uses.
The Deadline That Actually Matters
Under the FCBA, you must submit your dispute in writing to your card issuer within 60 days of the date the statement containing the disputed charge was mailed or made available to you. That's 60 days from the statement date, not from when you noticed the charge. Missing that window doesn't mean you're legally prohibited from asking, but you lose the FCBA's formal protections - the issuer is no longer legally required to investigate or credit your account while the dispute is pending. Check your statement date carefully and act quickly.
If the charge is the result of fraud or an unauthorized transaction, report it to your issuer immediately by phone to freeze further exposure, and then follow up in writing to trigger the FCBA process. Many issuers now accept disputes through their mobile app or online portal; confirm with your specific issuer whether that counts as the formal written notice required under the law.
How to Actually File the Dispute
Write a letter (or use a documented online submission) addressed to your card issuer's billing inquiries address - which is legally required to be listed on your statement and is usually separate from the payment address. Include your name, account number, the specific charge you're disputing with the date and amount, and a brief explanation of why it's wrong. Attach copies of any supporting documentation: receipts showing a different amount, cancellation confirmations, screenshots of a merchant's advertised policy. Keep the originals.
Send a written letter by certified mail, return receipt requested, so you have proof of when it arrived. The Consumer Financial Protection Bureau (CFPB) maintains a sample dispute letter template at consumerfinance.gov that California residents can use as a starting point.
Once your written dispute is received, the FCBA requires the issuer to acknowledge it within 30 days and resolve it within two billing cycles (but no more than 90 days). During that period, the issuer cannot report the disputed amount as delinquent to credit bureaus, and it cannot try to collect on it or close your account solely because of the dispute.
If the Issuer Rules Against You
If your issuer denies the dispute or closes it without crediting you, they must explain the decision in writing. You can respond with additional documentation and ask them to reconsider. If that fails, California residents have two meaningful next steps.

First, file a complaint with the CFPB at consumerfinance.gov/complaint. Card issuers are required to respond to CFPB complaints, and the bureau's complaint database is public - which gives the process some real teeth. Second, file a complaint with the California Attorney General's office at oag.ca.gov/consumers, which enforces California's Unfair Competition Law and can act on patterns of deceptive or unfair practices by financial institutions operating in the state.
If the disputed amount is significant and you believe the issuer violated the FCBA, consulting a consumer protection attorney is worth considering. California's consumer protection statutes, including the Consumer Legal Remedies Act, can provide remedies including actual damages and attorney's fees in certain cases, which means attorneys sometimes take these cases on contingency. Your county's bar association can provide referrals.
Protect Your Credit Report While the Dispute Is Pending
Monitor your credit reports during and after any dispute. Under federal law, you're entitled to free reports from all three major bureaus - Equifax, Experian, and TransUnion - at annualcreditreport.com, which is the official site. If a disputed charge appears as a delinquent account on your report while a legitimate FCBA dispute is unresolved, that itself may be a violation you can report to the CFPB and the California Attorney General. Document everything: dates, names of representatives you spoke to, and what they told you.
This is general information, not legal or financial advice. Dispute deadlines, issuer procedures, and applicable rules can change - verify the current FCBA process and your rights with the Consumer Financial Protection Bureau at consumerfinance.gov, and for California-specific consumer protection complaints, contact the California Attorney General's office at oag.ca.gov/consumers.
