How to File a Complaint With the California Department of Insurance
A step-by-step guide to filing a CDI complaint: what to include, what CDI can and cannot do, realistic timelines, and how to use the complaint process as leverage.

The California Department of Insurance (CDI) exists to regulate insurance companies and protect consumers. When your insurer is not playing by the rules — missing deadlines, refusing to communicate, denying claims without proper basis — you can file a complaint that puts a state regulator on the case. It is free, it does not require a lawyer, and it works more often than most people expect.
What CDI Can Do
The CDI has regulatory authority over all admitted insurers in California. When you file a complaint, an analyst reviews your situation and contacts the insurer. The CDI can:
- Require the insurer to respond in writing, explaining their position
- Investigate whether the insurer violated the Insurance Code or Fair Claims Settlement Practices Regulations
- Require corrective action if a violation is found
- Impose fines for regulatory violations
- Refer patterns of abuse for formal enforcement proceedings
- Issue a written determination of whether the insurer's conduct violated regulations
What CDI Cannot Do
Be realistic about the CDI's limitations:
- CDI cannot award you money. It is not a court and cannot order the insurer to pay your claim.
- CDI cannot resolve coverage disputes. If the dispute is about policy interpretation, CDI will note that it is a legal question beyond its scope.
- CDI cannot provide legal advice or represent you.
- CDI cannot force an insurer to change a coverage decision — only to follow proper procedures.
Despite these limitations, a CDI complaint is powerful. When an insurer knows a regulator is watching, behavior often changes. Claims that were stalled for months suddenly get attention. Adjusters who stopped responding suddenly call back. The complaint creates accountability.
When to File
File a CDI complaint when the insurer has violated procedural requirements or acted unreasonably:
- Failed to acknowledge your claim within 15 days (Cal. Code Regs., tit. 10, Section 2695.5(e))
- Failed to accept or deny within 40 days of receiving your proof of loss (Cal. Code Regs., tit. 10, Section 2695.7(b))
- Stopped communicating — not returning calls or responding to written inquiries
- Denied without citing specific policy language as required
- Failed to inform you of all coverages that apply to your loss (Cal. Code Regs., tit. 10, Section 2695.4(a))
- Failed to pay undisputed amounts while disputing the remainder
- Pressured you to accept a settlement without providing a fair basis for the amount
Cite the Specific Regulation
Your complaint is stronger when you cite the specific regulation the insurer violated. The California Fair Claims Settlement Practices Regulations are in the California Code of Regulations, Title 10, Sections 2695.1 through 2695.14. Reference the specific section number in your complaint. It tells the CDI analyst exactly what to investigate.
How to File: Step by Step
The CDI accepts complaints through its online portal. Here is the process:
- Go to the CDI website:Visit insurance.ca.gov and navigate to "File a Complaint" (or go directly to the complaint portal)
- Create an account (or log in if you have one)
- Select the complaint type:Choose "Property" and then the specific sub-category (claim handling delay, denial, underpayment, etc.)
- Provide your policy information: Insurer name, policy number, claim number, date of loss
- Describe the problem: Write a clear, factual narrative of what happened and what the insurer did wrong (see below for tips)
- Upload supporting documents: Attach your denial letter, relevant correspondence, your policy dec page, and any evidence of the violation
- Submit: You will receive a confirmation number and case assignment
What to Include in Your Complaint
The quality of your complaint determines how effectively CDI can act. Include:
- A clear timeline: Date of loss, date you reported the claim, key dates for inspections, correspondence, and deadlines missed
- The specific violation: What regulation or law the insurer violated, with citation if possible
- What you want: State specifically what outcome you are seeking — a response, a re-evaluation, payment of the undisputed amount, etc.
- Documentation: The denial letter, your disagreement letter, proof of mailing dates, the claim file correspondence
- Factual tone:State facts, not emotions. "The insurer has not responded to my three written inquiries dated March 5, March 19, and April 2" is stronger than "they are ignoring me."
Do Not Exaggerate
Stick to facts you can document. If you say the insurer missed a deadline, attach the correspondence showing the dates. If you say they failed to investigate, explain what investigation steps were skipped. Exaggeration or inaccuracy in your complaint undermines your credibility.
The Timeline
After you file, expect this general timeline:
- 1-5 business days: CDI assigns your case to an analyst
- 5-15 business days: CDI contacts the insurer and requests a response
- 15-30 days: Insurer provides its response to CDI
- 30-60 days: CDI analyst reviews both sides and issues a determination
Total resolution time is typically 30 to 90 days. Complex cases take longer. During this period, your claim continues — filing a CDI complaint does not pause the claims process or any deadlines that apply to you.
Using the CDI Complaint as Leverage
Here is the practical reality: sometimes the threat of a CDI complaint is as effective as actually filing one. When you write to the insurer and state that you will file a CDI complaint if the issue is not resolved by a specific date, many insurers take notice. They know that CDI complaints create a regulatory record. They know that too many complaints trigger Market Conduct examinations. They know that regulatory findings can be used against them in litigation.
But do not make empty threats. If you say you will file, follow through. And if the issue is already severe — months of delay, a clearly improper denial, refusal to communicate — file immediately rather than warning first. You can reference the CDI complaint in your communications with the insurer: "Please be advised that I have filed CDI Complaint No. [number] regarding your handling of this claim."
What Happens After CDI's Determination
CDI will send you a written determination. If CDI finds a violation, it will direct the insurer to take corrective action. If CDI does not find a violation, it will explain why. Either way, the CDI determination creates an official record that can be useful later — in appraisal, mediation, or litigation.
A CDI complaint does not replace your other options. You can file a CDI complaint AND hire a public adjuster or attorney. You can file a CDI complaint AND invoke appraisal. These processes run in parallel, not in sequence. Use every available tool. For more on your insurer's obligations, see our insurer obligations cheat sheet.
When CDI Is Not Enough
If the dispute is about coverage interpretation (not procedural violations), if the amount at stake is large, or if the insurer's conduct is so egregious that it constitutes bad faith, you likely need an attorney. CDI is a regulator, not your advocate. An attorney is your advocate. Use both. For guidance on when an attorney is necessary, see our article on what to do when your insurer is not responding.
The CDI exists because the legislature recognized that policyholders need protection from insurer misconduct. Filing a complaint is not adversarial — it is using the system as designed. If your insurer is not following the rules, report it. That is exactly what CDI is for.
