How to Dispute an Unauthorized Credit Card Charge in California
How long do I have to dispute a credit card charge in California?
Under the federal Fair Credit Billing Act, you generally have 60 days from the date the billing statement containing the charge was mailed to you to submit a written dispute to your card issuer. Some issuers offer longer informal windows as a customer-service policy, but 60 days is the legally protected timeframe. Check your cardholder agreement for your issuer's specific terms.
Does disputing a credit card charge hurt my credit score?
Disputing a charge does not by itself hurt your credit score. Under the Fair Credit Billing Act, your card issuer cannot report the disputed amount as delinquent to credit bureaus while the investigation is open. If the dispute is resolved in your favor, the charge is removed. If the issuer rules against you, you'll need to pay or the unpaid amount could eventually affect your credit.
Where do I report credit card fraud in California?
California consumers can report credit card fraud or billing disputes to the Consumer Financial Protection Bureau at consumerfinance.gov, which forwards complaints to the financial institution and tracks responses. The California Department of Financial Protection and Innovation, which oversees many California-licensed lenders and banks, also accepts complaints at dfpi.ca.gov. For deceptive merchant conduct, file with the California Attorney General at oag.ca.gov.
What if my credit card company denies my dispute?
If your card issuer sides with the merchant, you can escalate by filing a complaint with the Consumer Financial Protection Bureau at consumerfinance.gov or the California Department of Financial Protection and Innovation at dfpi.ca.gov. For smaller dollar amounts, California small claims court is an option without requiring an attorney. The issuer is also required to provide a written explanation of why it denied your dispute.
Can I dispute a credit card charge for a subscription I forgot to cancel?
Generally, a charge for a subscription you technically authorized - even if you forgot to cancel - is harder to dispute under the Fair Credit Billing Act, which primarily covers unauthorized charges and billing errors. Your best options are negotiating directly with the merchant for a refund or using your card's chargeback process, which depends on the card network's rules rather than federal statute. Rules vary by issuer.
An unfamiliar charge on your credit card statement can mean anything from a merchant billing error to outright fraud. California consumers have two overlapping sets of protections in this situation: federal law under the Fair Credit Billing Act, and California's own consumer statutes. Knowing how to use them, and in what order, makes the difference between a resolved dispute and a debt that quietly damages your credit.

What Counts as a Disputable Charge
The Fair Credit Billing Act, the federal law that governs credit card billing disputes, covers charges you didn't authorize at all, charges for goods or services you never received, charges for the wrong amount, and charges from a merchant whose identity doesn't match anything in your records. It also covers situations where a merchant didn't apply a return or credit you were promised. What it generally does not cover is a charge you technically authorized but are unhappy with afterward - that's a different process, sometimes called a chargeback claim, that depends more on the card network's rules and the merchant's return policy.
California law adds another layer. The state's Consumer Legal Remedies Act and Unfair Competition Law can apply when a merchant's conduct was deceptive, not just when a charge was unauthorized in the technical sense. But for most consumers dealing with a one-time billing error or a fraudulent charge, the federal dispute process is the fastest and most direct route.
The Dispute Window and Why It Matters
Under the Fair Credit Billing Act, you generally have 60 days from the date the statement containing the disputed charge was mailed to you to submit a written dispute to your card issuer. This is a firm statutory deadline, so if you spot a suspicious charge, don't wait. The clock runs from the statement date, not the date you noticed the charge.
Some card issuers advertise longer informal dispute windows - 90 days or more - as a customer-service policy, but those aren't federally required. Relying on your issuer's goodwill beyond the 60-day federal window puts you in a weaker legal position. Check your cardholder agreement for your issuer's specific terms, but treat 60 days as the deadline that matters.
How to File the Dispute
The Fair Credit Billing Act requires your dispute to be in writing, sent to the billing inquiries address listed on your statement - which is often a different address than where you send your payment. Many issuers now accept disputes through their app or website, and the Consumer Financial Protection Bureau has said electronic submission through a creditor's own platform can satisfy the writing requirement, but if the situation might escalate, a certified letter to the billing inquiries address creates a cleaner paper trail.
Your dispute letter should include your name, account number, the charge you're disputing (with the date and amount), and a brief explanation of why it's wrong. Attach any supporting documentation you have: screenshots of your account, a receipt that shows a different amount, a police report if your card number was stolen, or written confirmation of a canceled subscription. Keep copies of everything you send.
Once your issuer receives the dispute, federal law gives them 30 days to acknowledge it and 90 days, or two billing cycles, to resolve it - whichever comes first. During that period, the issuer cannot report the disputed amount as delinquent to credit bureaus, cannot charge interest on it while the investigation is open, and cannot require you to pay it while the dispute is pending. If the issuer finds in your favor, the charge is removed. If they find against you, they must explain why in writing, and you have the right to submit a rebuttal.
If Your Issuer Sides With the Merchant
An adverse decision from your card issuer isn't the end. If you believe the issuer handled your dispute incorrectly, you can escalate in a few ways.
First, you can file a complaint with the Consumer Financial Protection Bureau at consumerfinance.gov. The CFPB forwards complaints to the financial institution and tracks responses - issuers typically respond, because the CFPB monitors their complaint records. The California Department of Financial Protection and Innovation, the state agency that oversees many California-licensed financial institutions, accepts complaints at dfpi.ca.gov and has its own authority over state-chartered banks and certain fintech lenders.

Second, if the underlying merchant conduct was deceptive or fraudulent, you can file a complaint with the California Attorney General's office at oag.ca.gov. The AG's office doesn't mediate individual disputes, but complaints inform enforcement priorities, and a formal complaint creates a record if the situation later involves litigation.
Third, for disputes involving smaller dollar amounts - generally under $12,500 in California, though that limit adjusts periodically - small claims court is a realistic option if you can show the merchant or issuer acted wrongly. California's small claims process doesn't require an attorney.
Protecting Yourself Going Forward
Setting up transaction alerts through your card issuer's app is the single most practical step for catching unauthorized charges fast, well inside the 60-day window. Reviewing your statement monthly rather than relying on alerts alone is also worth doing, since some fraud involves small recurring charges designed to go unnoticed.
If your card number was compromised, request a new card number immediately - not just a freeze, since a freeze can be lifted and the same number reused. And if there are signs that a broader identity theft is happening (accounts you didn't open, credit inquiries you don't recognize), place a free credit freeze with all three major bureaus: Equifax, Experian, and TransUnion. California law also gives you the right to a free credit freeze under Civil Code Section 1785.11.2, and the bureaus are required to place one within one business day of a phone request or three business days of a mail request, per current statute.
This is general information, not legal or financial advice. Dispute timelines, issuer policies, and California statutory limits can change - verify current rules with the Consumer Financial Protection Bureau at consumerfinance.gov, the California Department of Financial Protection and Innovation at dfpi.ca.gov, and for AG complaints, the California Attorney General's office at oag.ca.gov.
