If the other driver’s insurance denies liability, it is taking the position that its insured is not responsible for your accident, or that the available evidence does not establish responsibility. That position is not a court judgment. Request the denial in writing, identify exactly what is disputed, preserve relevant evidence and ask for reconsideration with a clear explanation of any missing or incorrect facts. Do not let the insurance discussion distract you from medical care or legal deadlines.
This guide focuses on disputes about responsibility for a California collision. It provides general information, not advice about a particular claim.
First, Identify What the Insurance Company Denied
“Claim denied” can describe several different problems. Before sending more paperwork, determine which question the insurer is answering.
| Disputed issue | What it means | Useful next question |
|---|---|---|
| Liability | The insurer disputes who caused the collision. | Which actions or facts support its fault decision? |
| Coverage | The insurer says the policy does not cover the event or person. | What coverage issue or policy language is involved? |
| Injury causation | The insurer disputes whether the crash caused the claimed injury. | Which medical connection is being questioned? |
| Damages | The insurer disputes the amount or nature of the losses. | Which expenses or claimed losses are disputed, and why? |
More than one issue may be present. A treatment gap concerns the injury record; it does not, by itself, establish which driver caused a collision. Likewise, a policy exclusion is a different question from whether a driver acted negligently.
Ask for a Written Denial and Clarification
Under California Code of Regulations section 2695.7(b)(1), an insurer denying a third-party claim or disputing liability or damages must do so in writing. The same provision imposes more detailed explanation requirements for first-party denials, meaning claims under your own coverage. These requirements should not be treated as identical.
Save the letter, claim number and adjuster’s contact details. If the explanation is unclear, ask what facts support the decision and which information would address the dispute. You can request relevant records, but do not assume that you are entitled to the insurer’s entire internal claim file.
Keep a dated record of calls and follow up in writing when clarification matters. Note what the adjuster actually said, rather than your interpretation of their motives.
Match Your Evidence to the Reason for the Denial
A useful response answers the specific disputed point. Sending a larger file is not necessarily the same as supplying better evidence.
- Conflicting accounts: Identify available witnesses, video and contemporaneous photographs. Distinguish what someone personally saw from what they heard later.
- Disputed lane position or movement: Preserve scene photographs, road markings, the collision diagram and vehicle-damage photographs. Do not present your own reconstruction as an expert conclusion.
- Missing evidence: List the item, who may hold it, when it was requested and whether a response is outstanding.
- Disputed injuries or losses: Organize relevant medical records, bills, work restrictions and earnings information separately from evidence about how the crash happened.
Save original photographs and video files, not just edited clips or screenshots. Record the source and date. If footage may exist, ask about preservation promptly because retention practices vary. Our guide to requesting traffic-camera footage after an accident explains practical limitations as well as possible sources.
Do not coach witnesses or alter records. If an earlier statement was mistaken, identify the correction and explain it honestly. A short, accurate chronology is more useful than a confident account that fills gaps with guesses.
Use the Police Report Without Treating It as a Verdict
A report may contain observations, diagrams, witness information and statements that help evaluate the insurer’s decision. It does not automatically resolve a civil liability dispute. Separate what the officer observed from what a driver or witness reported.
Identify any factual error precisely and ask the issuing agency about its correction or supplemental-report procedure. Keep the original report and any later supplement. If the insurer disagrees with the report, ask which facts it disputes instead of assuming that either document settles every question.
Request Reconsideration With an Organized Response
- Identify the decision. Include the claim number, collision date and date of the denial.
- State the disputed point. Explain which factual conclusion you disagree with and why.
- Connect each attachment to that point. Label the files and describe what each shows, including its limitations.
- Ask for review. Request written confirmation that the new information was considered and clarification of any remaining dispute.
- Keep your own complete copy. Save what you sent, when you sent it and any acknowledgment.
This is a request for reconsideration, not a court appeal. Ask whether the insurer has a particular review process, but do not assume an internal review extends a lawsuit deadline. If a deadline is close, seek legal advice rather than waiting for another response.
What if the Insurer Says You Share Fault?
California comparative fault can reduce damages according to an injured person’s share of responsibility. CACI 405 addresses proof of the plaintiff’s negligence and its contribution to the harm. An adjuster’s proposed percentage is not itself a judicial finding.
If the dispute is specifically about an equal split, see our separate guide to challenging a 50/50 insurance fault decision. Here, the immediate task is to understand whether the insurer denies all responsibility or accepts some responsibility while disputing the allocation.
Your Own Insurance and Other Review Options
Notify your own insurer as required by your policy and ask which benefits may apply. Collision coverage may address covered vehicle damage, subject to policy terms and a deductible. A liability denial by another insurer does not automatically establish eligibility for uninsured-motorist benefits.
The California Department of Insurance’s accident guide explains claims and subrogation, including how your insurer may pursue recovery after paying a covered loss. Do not assume deductible recovery is guaranteed or sign away rights without understanding the effect on your insurer’s recovery rights.
You can also use the Department of Insurance’s consumer-help process to raise a claims-handling concern. A complaint is not a substitute for evaluating the legal claim or meeting filing deadlines. If reconsideration does not resolve the dispute, counsel can assess whether a claim against the responsible person or entity is appropriate. Do not assume the insurer is the proper defendant simply because it sent the denial.
Keep Reporting and Lawsuit Deadlines Separate
The California Courts’ deadline guide explains that personal injury lawsuits generally have a two-year limitation period and property-damage lawsuits generally have a three-year period. Exceptions and different rules can apply, particularly when a government agency or employee is involved. Have the applicable deadline checked for your circumstances.
Separately, the DMV requires an SR-1 report within 10 days when a California collision causes an injury, death or property damage exceeding $1,000. This is additional to reports to police or an insurer. Filing a report or continuing negotiations should not be assumed to preserve the right to sue.
Frequently Asked Questions
Can a liability denial be changed?
It may be reconsidered when additional information changes the assessment, but a reversal is not assured. Ask which issue remains disputed and respond with evidence relevant to that issue.
How long does it take to prove liability?
There is no dependable timeline for every collision. Available evidence, witness access and the nature of the dispute matter. Claim-handling deadlines are not a promise that a contested fault issue or lawsuit will be resolved within that period.
Should I give another recorded statement?
First identify who is requesting it and whether obligations under your own policy apply. Be truthful and do not guess. Our recorded-statement guide discusses the distinction between your insurer and another driver’s insurer. Seek advice if you do not understand a request; do not simply ignore policy duties.
Does no police report mean I cannot challenge the denial?
Not automatically. Photographs, witnesses, video and other records may still be relevant. The strength of the claim depends on the available facts, not solely on whether a report was made.
Does a denial prove the insurer acted in bad faith?
No. A disagreement or an adverse decision is not enough to establish bad faith. Claims under your own policy and claims against another driver’s insurer involve different legal relationships. An attorney can assess the applicable rights without assuming every denial supports a separate lawsuit against an insurer.
When Legal Review May Help
If a California crash caused significant injuries, the insurer disputes responsibility, or a filing deadline is approaching, State Law Firm’s car accident attorneys in Sherman Oaks can review the denial and available records. Bring the letter, correspondence, collision evidence and relevant injury documentation. A review can help identify unresolved questions and possible next steps; it cannot guarantee payment or a particular result.
