Proving Collusion in Insurance Practices

Understanding Collusion in Insurance

Collusion in insurance can have a serious impact on policyholders throughout California. When insurance companies, brokers, or other industry players secretly agree to fix prices, limit competition, or divide markets, consumers often pay the price. California law takes these antitrust violations seriously, and understanding how collusion works is the first step toward holding insurers accountable.

Collusion may appear in many forms, including coordinated premium rates, denying certain claims in unison, or dividing up customers among companies. If you suspect collusion, it’s important to know your rights and the legal standards that apply.

What Counts as Collusion?

To prove collusion, you must show that two or more parties agreed, either directly or indirectly, to restrict competition. California antitrust law, including the Cartwright Act, defines collusion as any contract, combination, or conspiracy that restrains trade. Common signs of collusion in insurance practices include:

• Identical premium increases across multiple insurers at the same time
• Unusual patterns of claim denials
• Evidence of companies sharing confidential pricing information
• Regional or demographic “carve-outs” where insurers avoid competition

If you notice these patterns, consider reviewing our Coverage Denials page for more insight into how insurers may act unfairly.

Key California Laws

California’s Cartwright Act (Business & Professions Code §§ 16700–16770) is the state’s primary antitrust law, prohibiting agreements that restrain trade. The federal Sherman Act also applies to insurance companies operating in California.

Highlights of these laws include:

• Prohibiting price fixing, bid rigging, and market allocation
• Allowing individuals to seek damages for antitrust violations
• Imposing penalties on companies that violate fair competition rules

How Collusion Hurts Policyholders

Collusion leads to higher premiums, reduced coverage, and unfair claim denials. California policyholders may experience:

• Limited options when shopping for insurance
• Inflated prices for basic coverage
• Delays or denials that seem coordinated across different insurers
• Reduced access to specialty or high-risk policies

These harms can appear across all types of insurance, including auto, homeowners, health, and business coverage. If you’ve experienced unfair treatment, our Steps to Fight Unfair Insurance Tactics article offers actionable advice.

Recognizing Signs of Collusion

While collusion can be difficult to spot, policyholders should watch out for:

• Similar rate adjustments announced simultaneously by multiple insurers
• Public statements suggesting insurers are aligning business strategies
• Consistent language in denial letters from different companies
• Trade association meetings where sensitive topics are discussed

Gathering Evidence

Proving collusion in insurance requires collecting solid evidence. Helpful documentation may include:

• Copies of policy documents and premium notices
• Claim denial letters from different insurers using identical reasoning
• Meeting records or statements from insurance trade groups
• News reports showing synchronized actions in the industry

Policyholders should also keep notes of phone calls and save all written communications with insurers. For tips on documenting your interactions, check How to Document Property Damage for Claims.

Working with Regulators

California’s Department of Insurance investigates antitrust violations and unfair business practices. If you suspect collusion, you can:

• File a complaint with the Department of Insurance
• Request a market conduct exam or investigation
• Cooperate with any requests for documents or testimony

The state may also coordinate with the federal Department of Justice if violations cross state lines. To learn more about regulatory actions, see California Coverage Denial Lawsuits.

Legal Strategies for Policyholders

If you believe you’ve been harmed by collusion, consider these steps:

• Consult with an attorney experienced in insurance antitrust claims
• Collect as much documentation as possible before filing suit
• Explore class action options if others are affected
• Review your policy for arbitration clauses or contractual remedies

Attain Law attorneys can help you understand your options and the best way to proceed. To see other related matters, visit our Bad Faith Claims and Coverage Denials pages.

Damages and Remedies

Victims of collusion may be entitled to:

• Compensation for overpaid premiums
• Recovery of denied or underpaid claims
• Treble damages (triple the amount of actual damages) under state and federal antitrust laws
• Injunctive relief to stop ongoing anticompetitive behavior

Real-World Examples

California has seen several high-profile cases where insurers were accused of price-fixing or market allocation:

• Coordinated auto insurance premium hikes after natural disasters
• Agreements among health insurers to exclude certain providers
• Market division between regional home insurers

While these cases can be complex, they demonstrate the importance of vigilance. For background on related litigation, visit California Antitrust Lawsuits in Insurance.

Avoiding Pitfalls

Proving collusion is challenging. Policyholders should avoid:

• Relying solely on anecdotal evidence
• Filing complaints without supporting documents
• Assuming all similar insurer actions are illegal (some coordination may be allowed under state law)

A qualified attorney can help separate coincidence from actionable collusion. For more on challenging denial decisions, review How to Challenge Wrongful Coverage Denials.

Taking Action

If you suspect collusion, here’s what you can do:

• Gather documents, letters, and rate notices
• Contact the California Department of Insurance
• Discuss your situation with an attorney
• Consider joining or starting a class action if multiple consumers are affected

You’re not alone in this fight. For more resources, check our Insurance Practice Area and Bad Faith Claims pages.
