The Insurer's Duty to Investigate: When a Sloppy Investigation Becomes Bad Faith

Every insurance company in California has a legal obligation to conduct a thorough, fair, and objective investigation of every claim. This isn't optional — it's mandated by the California Insurance Code, the Fair Claims Settlement Practices Regulations, and decades of case law. When an insurer fails to properly investigate and denies or underpays your claim as a result, that failure can itself constitute bad faith — regardless of whether the claim would ultimately have been covered.

The Legal Foundation

The insurer's duty to investigate comes from multiple sources:

• Insurance Code § 790.03(h)(3): It is an unfair claims settlement practice to fail to adopt and implement reasonable standards for the prompt investigation and processing of claims.
• Insurance Code § 790.03(h)(4): Failing to affirm or deny coverage within a reasonable time after proof of loss has been completed.
• 10 CCR § 2695.7(d): Every insurer shall conduct and diligently pursue a thorough, fair and objective investigation and shall not persist in seeking information not reasonably required for or material to the resolution of a claim dispute.
• The implied covenant of good faith and fair dealing: Every insurance contract includes an implied promise that the insurer will deal fairly with the insured. A shoddy investigation violates that promise.

What a Proper Investigation Looks Like

A thorough investigation means the insurer must:

1. Timely acknowledge and begin investigating. Under 10 CCR § 2695.5(e), the insurer must acknowledge the claim and begin investigation within 15 calendar days of receiving notice.
2. Inspect the property. The insurer must physically inspect the damage — not just rely on photos, satellite imagery, or desk reviews. For complex losses, this may require multiple inspections, destructive testing, or specialized experts.
3. Consider all available evidence.The insurer cannot cherry-pick evidence that supports a denial while ignoring evidence that supports coverage. They must consider the policyholder's documentation, contractor estimates, expert reports, and any other evidence submitted.
4. Disclose all applicable coverages. Under 10 CCR § 2695.4(a), the insurer must disclose to the claimant all benefits, coverages, time limits, or other provisions that may apply to the claim. They cannot stay silent about a coverage that might benefit you.
5. Communicate findings.The insurer must explain what they found, what they're paying, what they're not paying, and why — in writing, with specific policy references.
6. Not seek irrelevant information. The insurer cannot use the investigation as a fishing expedition — demanding years of financial records, unrelated medical history, or other information not material to the claim.

Signs of an Inadequate Investigation

• Drive-by or cursory inspection.The adjuster spent 20 minutes on a six-figure loss. They didn't go in the attic, crawl space, or behind walls. They took a few photos and left.
• Desk review only. The insurer made a coverage decision based on photos or a Google Earth review without ever sending someone to the property.
• Ignoring your evidence.You submitted a contractor estimate, an engineer's report, or photos of damage. The insurer's estimate doesn't address or even mention this evidence.
• Using biased experts. The insurer hired an engineer or hygienist who always produces insurer-favorable results, and relied on that report without independent verification.
• Failing to investigate promptly. Months pass with no inspection, no communication, no progress. Delay is itself an investigation failure.
• Premature denial. The insurer denied the claim before completing the investigation — sometimes before even inspecting the property.
• Failing to disclose applicable coverages. The insurer pays on Coverage A but never mentions that ordinance or law, debris removal, or other coverages also apply.

Your Rights During the Investigation

• You can be present during inspections.Don't let the adjuster inspect alone. Be there (or have your representative there) to point out damage and ensure it's documented.
• You can have your own expert present.Bring your contractor, Public Adjuster, or other professional to the inspection. They can identify damage the insurer's adjuster might miss or minimize.
• You can request copies of the insurer's reports. Under California law, the insurer must provide copies of all reports, estimates, and documentation related to your claim.
• You can submit your own evidence at any time.The insurer must consider evidence you submit. If you get a contractor estimate after the insurer's initial inspection, submit it and demand they incorporate it into their analysis.

What to Do If the Investigation Is Inadequate

1. Document the deficiency in writing. Send a letter (email or certified mail) to the adjuster and their supervisor identifying specifically what was inadequate: areas not inspected, evidence not considered, damage not documented.
2. Demand a re-inspection. Request that the insurer send a more experienced adjuster or a qualified expert to conduct a proper inspection.
3. Submit your own documentation. Hire your own contractor, engineer, or professional to inspect and document the damage. Submit their report to the insurer with a demand that it be considered.
4. File a CDI complaint.A complaint with the California Department of Insurance creates an official record of the insurer's failure to investigate. See filing a CDI complaint.
5. Consider professional representation. A Public Adjuster can take over the claims process and ensure the investigation is conducted properly. If bad faith is clear, an attorney can pursue damages beyond the policy.
