How to Write a Personal Injury Demand Letter in California (+ Template)
A personal injury demand letter is a written document you send to the at-fault party's insurance company that describes your accident, your injuries, your financial losses, and the specific amount you are demanding to settle the claim. It is the formal opening of settlement negotiations, and a well-built demand letter, backed by medical records and proof of your losses, is often what moves an insurer from a lowball offer to a fair one. This guide explains what to include, how the timing works under California's statute of limitations, the special rules that apply to policy-limits demands under CCP 999, and a template you can follow. If you want it done right the first time, call (949) 325-7790 for a free consultation. No fee unless we win.
A personal injury demand letter is usually sent after your medical treatment has stabilized, so the full extent of your injuries and costs is known. It sets out who was at fault, what injuries you suffered, what those injuries have cost you (and will cost you), and the dollar amount you are willing to accept to resolve the claim. It is not a lawsuit; it is an attempt to settle before one becomes necessary. Most personal injury claims in California settle at this stage, which is why the quality of the demand letter matters so much.
What to Include in a California Demand Letter
A strong demand letter is specific, organized, and supported by evidence. It should contain:
The date, location, and facts of the accident, told clearly and chronologically
Why the other party is at fault, tied to the evidence (police report, photos, witness statements)
A description of your injuries and the treatment you received
Your economic damages, itemized: medical bills, lost wages, property damage, and future medical or wage costs
Your non-economic damages, such as pain and suffering and loss of enjoyment of life
A specific demand amount and a deadline to respond
Supporting documentation attached: medical records and bills, wage-loss proof, and photos
Keep the writing tight and factual. Adjusters read hundreds of these; a focused letter that proves each dollar of the demand is more persuasive than a long, emotional one.
Timing: The California Statute of Limitations
A demand letter does not stop the legal clock. Under California Code of Civil Procedure section 335.1, you generally have two years from the date of the injury to file a personal injury lawsuit. If your claim is against a government entity, you must file an administrative claim within six months. Sending a demand letter does not extend these deadlines, so you should send your demand with enough time left to file suit if the insurer refuses to settle. Waiting until the deadline is near weakens your position, because the insurer knows you are running out of time.
Special Rules for Policy-Limits Demands: California CCP 999
This is where California law is different from the generic demand-letter advice you will find online, and where getting it wrong can cost you. If you are making a time-limited demand to settle within the at-fault party's insurance policy limits, a specific statute applies: California Code of Civil Procedure sections 999 through 999.5, effective January 1, 2023.
Under CCP 999, a compliant time-limited policy-limits demand must:
Be in writing and labeled a "time-limited demand" or expressly reference section 999
Give the insurer at least 30 days to accept (if sent by email, fax, or certified mail) or at least 33 days (if sent by regular mail)
Make a clear, unequivocal offer to settle all claims within policy limits, including satisfaction of all liens
Offer a complete release of the insured from present and future liability for the occurrence
State the date and location of the loss, the claim number if known, and describe all known injuries
Include reasonable proof supporting the claim, such as medical records or bills
Why this matters: a properly made and unreasonably rejected policy-limits demand is one of the things that can later expose the insurer to liability beyond the policy limits if the case goes to trial and the verdict is larger. But if the demand does not substantially comply with CCP 999, it generally will not count as a reasonable settlement offer, and the policy limits will not be "opened," meaning the insurer cannot be forced to pay more than the policy amount. A short deadline or a missing required term can quietly defeat the entire purpose of the demand.
Two important limits on the statute: CCP 999 applies only to auto, motor vehicle, homeowner, and commercial premises liability policies for injury, property damage, and wrongful death claims, and it does not apply to claimants who are not represented by an attorney. That second point is significant, if you are handling your own claim, the strict 999 rules do not bind you, but you also lose the leverage that a compliant, attorney-issued policy-limits demand creates.
Personal Injury Demand Letter Template
Below is a general structure you can adapt for a standard (non-policy-limits) demand letter. For a policy-limits demand, the CCP 999 requirements above must be built in, which is one of the clearest reasons to have an attorney prepare it.
[Your Name]
[Your Address]
[Date]
[Claims Adjuster Name]
[Insurance Company Name]
[Address]
Re: Claim No. [number]
Claimant: [Your Name]
Date of Loss: [date]
Your Insured: [at-fault party's name]
Dear [Adjuster Name]:
I am writing to demand settlement of my claim for injuries I
suffered in the [date] accident caused by your insured.
The Accident. On [date] at [location], your insured [describe
what the at-fault party did]. As shown by the enclosed police
report and photographs, your insured was at fault.
My Injuries and Treatment. As a result, I suffered [injuries].
I was treated at [providers] and underwent [treatment]. The
enclosed medical records document my diagnosis and care.
My Damages. I have incurred the following losses to date:
Medical expenses: $[amount]
Lost wages: $[amount]
Property damage: $[amount]
Future medical care: $[amount]
----------------------------------------
Total economic damages: $[amount]
In addition, I have experienced significant pain, suffering,
and loss of enjoyment of life as described above.
Demand. To resolve this claim in full, I demand [$amount].
Please respond in writing by [date].
Enclosures: police report, medical records and bills,
wage-loss documentation, photographs.
Sincerely,
[Your Name]
This template is a starting point for education, not legal advice for your specific claim. The right demand amount, the strongest way to frame fault, and whether to make a policy-limits demand under CCP 999 all depend on the facts of your case.
Common Mistakes to Avoid
Sending it too early. Demanding before your treatment stabilizes means you cannot account for future costs, and you generally cannot reopen a settled claim.
Guessing at the value. Undervaluing pain and suffering or omitting future care leaves money on the table.
A defective policy-limits demand. A too-short deadline or a missing CCP 999 term can strip away the leverage a policy-limits demand is meant to create.
Giving a recorded statement first. Insurers use early statements to dispute fault or minimize injuries before you have made your demand.
Can I write my own personal injury demand letter in California?
Yes, you can write your own demand letter, and for a minor claim with clear liability that may be enough. But valuing the claim correctly, especially future medical costs and pain and suffering, is difficult without experience, and insurers tend to offer less to unrepresented claimants. For a policy-limits demand, the strict CCP 999 rules apply only when an attorney is involved, so the leverage those rules create is generally available only through counsel.
How long should I give the insurance company to respond?
For a standard demand, a common window is 30 days. For a time-limited policy-limits demand governed by CCP 999, you must give the insurer at least 30 days to accept if the demand is sent by email, fax, or certified mail, or at least 33 days if sent by regular mail. A deadline shorter than the statute allows can make a policy-limits demand non-compliant and strip away its legal effect.
How much should I demand in my letter?
Your demand should reflect the full value of your claim: all economic damages (medical bills, lost wages, future care, property damage) plus non-economic damages (pain and suffering, loss of enjoyment of life). It is common to demand somewhat more than your target to leave room for negotiation, but an unrealistically high number can undermine credibility. Because California does not cap general damages in ordinary injury cases, the value turns on documentation, not a formula.
What happens after I send the demand letter?
The insurer typically responds with an acceptance, a rejection, or, most often, a counteroffer that begins negotiation. If you reach an agreement, you sign a release and receive payment. If negotiations fail, the next step is usually filing a lawsuit before the statute of limitations expires. A properly made and rejected policy-limits demand can also become important later if a jury awards more than the policy limit.
Does a demand letter extend the statute of limitations?
No. Sending a demand letter does not pause or extend the deadline to file a lawsuit. In California you generally have two years from the injury under Code of Civil Procedure section 335.1 (six months for claims against a government entity). Always send your demand with enough time remaining to file suit if the insurer refuses to settle.
