How to Dispute an Unauthorized Credit Card Charge in California: What Federal and State Law Actually Give You
How long do I have to dispute an unauthorized credit card charge?
Under the federal Fair Credit Billing Act, you have 60 days from the date the statement containing the charge was mailed or made available to you to submit a written dispute to your card issuer. That window is strict, so acting as soon as you spot an unfamiliar charge is important. Missing it weakens your legal protections significantly.
Does calling my credit card company count as filing a dispute?
A phone call alone does not trigger the full legal protections of the Fair Credit Billing Act. You need to follow up in writing, sent to the issuer's designated billing inquiries address, which is typically different from the payment address on your bill. Many issuers accept written disputes through their secure online portal, which also creates a time-stamped record.
What happens to the disputed charge while my credit card company investigates?
Most card issuers issue a provisional credit to your account for the disputed amount while they investigate. The card company must acknowledge your dispute within 30 days and resolve it within two billing cycles, up to a maximum of 90 days. During that period, the issuer cannot report the disputed amount as delinquent or try to collect it from you.
Who do I complain to if my credit card company denies my dispute unfairly?
You can file a complaint with the Consumer Financial Protection Bureau at consumerfinance.gov, which has oversight authority over large credit card issuers and publishes complaints in a public database that companies typically respond to. If the issuer is a national bank, the Office of the Comptroller of the Currency is another federal escalation path. California residents can also contact the state Attorney General at oag.ca.gov.
Can I dispute a charge in California if I authorized it but the product was defective or misrepresented?
A charge you authorized isn't typically covered as a billing error under the Fair Credit Billing Act, which focuses on unauthorized charges and clear billing mistakes. If you believe the merchant committed fraud or misrepresented what they sold, your best path is a complaint to the California Attorney General at oag.ca.gov, the Federal Trade Commission at ftc.gov, or your county district attorney's consumer protection unit.
An unfamiliar charge on your credit card statement can mean a merchant error, a subscription you forgot you signed up for, or outright fraud. Whatever the cause, federal law and California consumer protections give cardholders a formal process to fight it - but the clock starts the moment that statement arrives.

The Federal Baseline: What the Fair Credit Billing Act Requires
The Fair Credit Billing Act, a federal law administered by the Consumer Financial Protection Bureau, is the main tool for disputing credit card charges. It covers billing errors, unauthorized charges, charges for goods or services never delivered, and charges for items that arrived significantly different from what was described. The law requires you to send a written dispute to your card issuer within 60 days of the date the statement containing the charge was mailed or made available to you. That 60-day window is firm, so acting promptly matters.
Your dispute letter must go to the issuer's designated billing inquiries address, which is typically different from the payment address printed on your bill. The card company is then required to acknowledge your dispute in writing within 30 days and must resolve it within two billing cycles, but no later than 90 days from receiving your complaint. While the dispute is under investigation, the issuer cannot try to collect the disputed amount, report it as delinquent to a credit bureau, or close your account solely because you disputed a charge.
How to Actually File the Dispute
Call your card issuer first to flag the charge and get the correct mailing or secure-message address for billing disputes. Many issuers now accept written disputes through their online portal or secure messaging system, which creates a time-stamped paper trail. Whether you use the portal or physical mail, follow up in writing regardless - a phone call alone does not trigger the legal protections of the Fair Credit Billing Act.
Your written dispute should include: your name, account number, the date and amount of the charge you're contesting, and a brief explanation of why it's an error or unauthorized. Attach copies of anything that supports your case - a receipt showing a different amount, a cancellation confirmation, a screenshot of a fraudulent transaction alert. Send physical mail by certified mail with return receipt so you have proof of delivery and the date. Keep copies of everything you send.
Your card issuer will typically issue a provisional credit to your account while it investigates. If the dispute is resolved in your favor, that credit becomes permanent. If it's resolved against you, the issuer must explain why in writing, and you have the right to request the documentation it relied on.
California's Additional Protections
California's Consumer Legal Remedies Act and Unfair Competition Law give state residents additional remedies if a merchant engaged in deceptive billing practices. If the dispute involves outright fraud - someone stole your card number, for example - you can also report it to the California Attorney General's office at oag.ca.gov, which tracks fraud patterns even when it can't intervene in individual cases. For identity theft connected to the charge, the California Office of Privacy Protection, operating under the California Department of Justice, offers specific guidance at oag.ca.gov/privacy.
If a debt collector later contacts you about the disputed amount before the dispute is resolved, California's Rosenthal Fair Debt Collection Practices Act provides protections beyond the federal Fair Debt Collection Practices Act, including covering original creditors. You can file a complaint about a debt collector's conduct through the California Department of Financial Protection and Innovation at dfpi.ca.gov.
If Your Dispute Is Denied
A denial isn't the end of the road. You can escalate a complaint about how your bank handled the dispute to the Consumer Financial Protection Bureau at consumerfinance.gov, which has supervisory authority over large card issuers, or to the Office of the Comptroller of the Currency if the issuer is a national bank. The CFPB's complaint database is public, and issuers generally respond to complaints filed there.

If the disputed amount is large enough and you believe the merchant engaged in fraud or deception, small claims court in California allows claims up to $12,500 for individuals as of current state rules, though you should verify the current limit at courts.ca.gov before filing. And if you used the card to pay for something in California that turned out to be deceptive, the state's Unfair Competition Law may give you grounds for a private civil claim or for filing with the Attorney General.
A Few Things That Can Undermine Your Dispute
Missing the 60-day window is the most common problem - it doesn't eliminate your ability to complain, but it removes the strongest statutory protections. Disputing only by phone without a written follow-up is the second most common mistake. And disputing a charge you actually authorized, even if you're unhappy with the product or service, is a chargeback situation that may be governed by different rules; the FCBA covers billing errors and unauthorized use, not general dissatisfaction with a merchant.
If you authorized a charge but believe the merchant committed fraud or misrepresented what they were selling, that's a separate complaint path: file with the California Attorney General at oag.ca.gov, the Federal Trade Commission at ftc.gov, or your county district attorney's consumer protection unit.
This is general information, not legal or financial advice. Dispute windows, issuer processes, and small claims limits can change - verify current rules with the Consumer Financial Protection Bureau at consumerfinance.gov, the California Courts self-help center at courts.ca.gov, and the California Attorney General at oag.ca.gov.
