What you're looking at when you receive a demand for arbitration
A demand for arbitration is a formal written request from the other driver's insurance company asking you to resolve a dispute outside of court. In California, when you have uninsured motorist coverage and disagree with your own insurance company about how much your claim is worth, either side can demand arbitration instead of going to trial. The demand letter outlines what the other party believes you owe or what they believe they should receive, and it proposes that an arbitrator (a neutral third party) make the final decision.
This is not the same as a lawsuit. You are not being sued. Instead, both sides are agreeing to let someone other than a judge decide the outcome. The demand letter itself is the formal notice that this process is starting.
Key Takeaways
- A demand for arbitration is a written notice that one side wants to resolve a disagreement through an arbitrator instead of court.
- In California uninsured motorist cases, either your insurance company or the other driver can demand arbitration if you disagree about the claim value.
- The demand letter states the amount being claimed, the facts supporting that amount, and the proposed arbitration process.
- You have a limited time to respond to the demand, and ignoring it can result in a default judgment against you.
- A sample demand shows you the language, structure, and information insurance companies typically include when making this formal request.
Why insurance companies use arbitration demands in California
California law allows uninsured motorist disputes to go to arbitration when the two sides cannot agree on the value of a claim. Your insurance company might demand arbitration if they believe the other driver's demand for money is too high. The other driver (or their representative) might demand arbitration if they think your insurance company's settlement offer is too low. Arbitration is faster and less expensive than a court trial, and the decision is binding — meaning both sides must accept the arbitrator's ruling.
The demand letter is the formal trigger that starts this process. Once one side sends it, the other side has a set number of days to respond. If you do not respond, the arbitrator may proceed without your input, which usually results in a decision against you.
What information appears in a typical demand for arbitration
A sample demand letter includes several standard sections. The opening identifies the parties involved (your name, the other driver's name, the insurance company), the date of the accident, and the policy number. It then restates the facts of the accident as the demanding party sees them — who was at fault, what injuries or damage occurred, and why the other side's position is unreasonable.
The demand also includes a specific dollar amount. This is the sum the demanding party believes should be awarded. For uninsured motorist claims, this might be the full amount the other driver is claiming, or it might be a lower figure if your insurance company is the one demanding arbitration. The letter explains how this amount was calculated — for example, medical bills plus lost wages plus pain and suffering.
The demand then proposes the arbitration process itself. It names the arbitrator or arbitration service (often JAMS or AAA in California), explains the rules that will explore, and states the important date for the other side to respond. It also typically includes language about where the arbitration will take place, whether it will be in person or by video, and who pays the arbitrator's fees.
How a sample demand differs from what you might actually receive
A sample demand for arbitration shows you the structure and language, but your actual demand will be specific to your accident, your injuries, and the amounts in dispute. The sample uses placeholder names and generic dollar figures. Your real demand will have your actual policy number, the exact date of your accident, the specific medical providers you saw, and the precise amount being claimed.
Samples are useful because they show you where to look for key information — the important date to respond, the arbitrator's name, the amount being claimed, and the contact person handling the case. They also show you the tone and formality you should expect. But do not assume your demand will match a sample word-for-word. Insurance companies and their attorneys customize each demand based on the individual claim.
What you need to do after receiving a demand
Read the demand carefully and note the response important date. In California, you typically have 30 days to respond, though this can vary. Do not ignore the important date. Contact your insurance company when ready if you received the demand — they may handle the response for you, or they may need your input on certain facts.
If you do not have an insurance company (because you are uninsured), or if the demand is directed at you personally, you should contact an attorney. Responding to a demand for arbitration requires understanding California law and the specific terms of your policy. An attorney can help you decide whether to accept the arbitration, propose a different amount, or challenge the demand itself.
Do not send money or make any admission of fault in response to the demand. Your response should be formal and written, ideally through an attorney or your insurance company's claims department.
The arbitration process after the demand is accepted
Once both sides have responded to the demand and agreed to arbitration, the arbitrator is selected. In California, arbitrators are often retired judges or attorneys with experience in personal injury law. The arbitrator sets a hearing date, usually within 60 to 90 days of the demand being sent.
Before the hearing, both sides exchange documents — police reports, medical records, repair estimates, photos of the accident scene, and written statements. This is called discovery. Each side also prepares a written brief explaining their position and the law supporting it.
At the hearing, both sides present their case to the arbitrator. You or your representative can present evidence, call witnesses, and argue why your position is correct. The other side does the same. The arbitrator then makes a decision, which is final and binding. You cannot appeal an arbitrator's decision in most cases, even if you disagree with it.
How to use a sample demand to understand your own
When you receive your actual demand for arbitration, compare it to a sample to make sure you understand each section. Check that all the facts about the accident are stated correctly. Verify that the dollar amount makes sense based on your medical bills and other losses. Confirm that the important date to respond is clearly marked and that you know who to contact with your response.
A sample also helps you spot red flags. If the demand claims facts that are not true, or if the amount seems wildly inflated, these are things your attorney or insurance company should address in the response. If the arbitration process described seems unfair — for example, if it gives one side more time to prepare than the other — that is also something to raise.
Keep the sample and your actual demand together for reference. Highlight the key dates and amounts in your demand so you do not miss anything important.
Frequently Asked Questions
What happens if I ignore a demand for arbitration?
If you do not respond by the important date, the arbitrator may proceed without your input and issue a default decision against you. This usually means the other side wins and you may owe the full amount they demanded. Contact your insurance company or an attorney when ready if you receive a demand.
Can I refuse to go to arbitration?
In most cases, no. California law allows either side to demand arbitration in uninsured motorist disputes, and once the demand is made, arbitration is the required process unless both sides agree otherwise. Your insurance policy also likely includes an arbitration clause that you agreed to when you purchased the policy.
Do I have to pay for the arbitrator?
Costs are usually split between the two sides, though this can vary. The demand letter will specify who pays what. In some cases, the losing side pays all fees. Ask your insurance company or attorney about the fee arrangement in your case.
Is arbitration faster than going to court?
Yes, arbitration is typically faster. A court trial can take a year or more to schedule. Arbitration hearings usually happen within 60 to 90 days of the demand being sent. However, the time between the demand and the hearing can still involve weeks of document exchange and preparation.
Can I appeal an arbitrator's decision?
California law limits appeals of arbitration decisions. You can only appeal if the arbitrator made a serious legal error or if there was fraud or misconduct. You cannot appeal straightforward because you disagree with the decision or think the amount is wrong. This is one reason it is important to prepare thoroughly for the arbitration hearing.
