How to Dispute a Bill in California: A Consumer's Guide
California consumers have strong legal protections when disputing incorrect or unfair bills from service providers, medical facilities, and other businesses. State law provides specific timeframes and procedures for contesting charges, with additional protections under the California Consumer Legal Remedies Act and Fair Debt Collection Practices Act.
Timing is critical when disputing bills in California - most consumer protection laws require you to contest charges within 30-60 days of receiving the bill. Failing to dispute within these timeframes may limit your legal options and ability to resolve the issue favorably.

Contact the company directly
5 days after startingBefore escalating, attempt to resolve the dispute directly with the company. Call their customer service department and explain the issue.

Send the dispute letter via certified mail
12 days after startingMail your dispute letter with return receipt requested to the company's designated billing disputes address (usually found on your bill or the company's website).

California residents have additional protections under the Song-Beverly Credit Card Act.
Wait for the company's response
44 days after startingCompanies typically have 30 days to respond to billing disputes.

Document if the company fails to respond within the timeframe.
File a complaint with regulatory agencies
50 days after startingIf the company doesn't resolve your dispute satisfactorily, file a complaint with the appropriate California regulatory agency.

Consider small claims court
60 days after startingIf other methods fail, you can file a claim in California small claims court for disputes up to $10,000. Prepare a Small Claims Court Complaint with all your evidence. California requires you to demand payment before filing (your dispute letter satisfies this).

The company will be served with your complaint and a hearing date will be set.
Prepare for and attend the small claims hearing
75 days after startingOrganize all your documentation chronologically. Bring at least three copies of everything (for you, the judge, and the opposing party). Be prepared to clearly explain the dispute, your attempts to resolve it, and why you believe you're entitled to relief.

Frequently Asked Questions
The first step is to contact the service provider or merchant directly. Send a written dispute letter that clearly identifies the bill, explains why you're disputing it, and includes copies of any supporting documentation. California law requires businesses to respond to billing disputes, and putting your dispute in writing creates a paper trail. Keep copies of all correspondence and note the dates and names of people you speak with.
Yes. For credit card billing disputes, under the federal Fair Credit Billing Act, you must dispute the charge within 60 days of the statement date on which the error appeared. For medical bills, you typically have 30-180 days depending on the provider. For utility bills, the California Public Utilities Commission generally requires disputes to be filed within 5 business days of receiving the bill to avoid disconnection during the dispute process. Other types of bills may have different timelines, so it's best to act quickly.
It depends on the type of bill. For credit card disputes, you can withhold payment on the disputed amount (but not the entire bill) while the investigation is pending. For utility services, California law protects you from disconnection while a bill is being legitimately disputed. For other types of bills, withholding payment could potentially lead to collection actions or negative credit reporting, so it's often advisable to pay the undisputed portion while the dispute is resolved.
California offers several resources: The California Department of Consumer Affairs handles many consumer complaints. The California Public Utilities Commission regulates utility billing disputes. The Department of Managed Health Care helps with health insurance billing issues. The California Attorney General's Office handles consumer fraud cases. Additionally, county consumer protection offices and the Better Business Bureau can assist with local business disputes.
Keep copies of: the original bill or statement; all correspondence with the company (letters, emails); notes from phone conversations (including date, time, and representative's name); proof of payments; any contracts or service agreements; delivery confirmations for dispute letters; and any responses from the company. California's 'unfair business practices' laws under the Business and Professions Code may require this documentation if you need to escalate your dispute.
Yes. If you cannot resolve a billing dispute directly, you can file in California small claims court for disputes up to $10,000 (for individuals). The process is designed to be navigated without an attorney. You'll need to file in the county where the business is located or where the transaction occurred. Before filing, send a formal demand letter giving the business a reasonable time to respond (typically 7-15 days). California courts provide self-help resources for small claims cases on their website.
California has strong consumer protection laws. The Consumers Legal Remedies Act prohibits unfair and deceptive business practices. The Unfair Competition Law bans unfair, deceptive, and unlawful business practices. The California Consumer Privacy Act provides rights regarding personal information. For medical bills, the Hospital Fair Pricing Act requires hospitals to provide financial assistance policies. Additionally, California follows federal protections like the Fair Credit Billing Act and the Fair Debt Collection Practices Act.
First, send a written cancellation notice via certified mail with return receipt. California's Automatic Renewal Law requires businesses to provide an easy cancellation method. If billing continues, send a formal dispute letter referencing this law. Document all communications. File complaints with the California Department of Consumer Affairs and the Attorney General's Office. You may also have grounds for a small claims case for all unauthorized charges. For subscription services, you can dispute the charges with your credit card company under the Fair Credit Billing Act.
Start by requesting an itemized bill and reviewing it for errors. Contact the provider's billing department in writing to dispute specific charges. California's Hospital Fair Pricing Act requires hospitals to have financial assistance policies for low-income patients. For insured patients, file an appeal with your insurance if they denied coverage. The Department of Managed Health Care can help with insurance disputes. For billing errors, contact the California Medical Board. Consider requesting a medical bill advocate through your insurance or hiring an independent one for complex disputes.
If your disputed bill is sent to collections, you have rights under California law. Within 30 days of being contacted by a collector, send a written dispute letter requesting debt validation. Under California's Rosenthal Fair Debt Collection Practices Act (which provides stronger protections than the federal FDCPA), debt collectors must cease collection efforts until they provide proof of the debt. You can also file complaints with the California Attorney General's Office and the Consumer Financial Protection Bureau. If the collector reports the debt to credit bureaus, you can add a statement to your credit report explaining the dispute.
