Step-by-Step: Suing an Internet / Cable Provider in California
Confirm your claim is within California's $12,500 limit
California's small claims limit is $12,500 (Individuals. Businesses capped at $6,250.). If your damages are higher, you can reduce your claim to the limit or file in California civil court. Use our California Small Claims Limit guide for the full details.
Send a demand letter first
File a complaint with the FCC at fcc.gov/consumers and your state's Public Utilities Commission before or alongside your small claims case. Providers must formally respond to these complaints. Courts in California expect plaintiffs to have made a good-faith attempt to resolve the dispute. A demand letter also creates a paper trail and often prompts payment without any court filing.
Gather your evidence
Your case is only as strong as your evidence. Collect everything before filing — see the checklist below for exactly what you need for a internet / cable provider dispute.
Find the right California courthouse
File at the Small Claims Court in the California county where the internet / cable provider is located, does business, or where the dispute occurred. Before filing, look up the internet / cable provider's correct legal name and registered agent on the California Secretary of State →. Using the wrong legal name is a common reason cases are dismissed.
Pay the filing fee ($30–$100)
California small claims filing fees range from $30 to $100 depending on your claim amount. Use our California Filing Fee Calculator to find the exact amount for your claim. Keep your file-stamped copy.
Serve the defendant properly
The internet / cable provider must be formally notified of the lawsuit. California courts provide specific instructions — follow them exactly. Improper service is one of the most common reasons cases are dismissed.
Present your case at the hearing
Bring 3 organized copies of all evidence. Present your case in order: what happened, how much you lost, and why the internet / cable provider is responsible. Most California small claims hearings last 15–30 minutes. Stay calm, stick to facts, and let the judge ask questions.
Sample Demand Letter: Internet / Cable Provider Dispute
Send this demand letter via certified mail before filing. Courts view prior good-faith attempts favorably, and many disputes settle at this stage. Replace the bracketed placeholders with your details.
I am writing to demand a refund of $[AMOUNT] from [DEFENDANT NAME] for [INCIDENT DESCRIPTION] that occurred beginning on or around [DATE]. As [PLAINTIFF NAME], you billed me for services that were not provided at the speeds or reliability levels guaranteed in my service agreement, applied charges I never authorized, or imposed an early termination fee that was not enforceable under the terms of our contract. Despite multiple contacts with your customer support team, this matter has not been resolved and the disputed amounts have not been refunded. If you do not issue a full refund within 14 days of the date of this letter, I will file a claim against you in small claims court and seek all applicable remedies.
