A demand letter is not a court filing and has no legal force of its own. It is the settlement package that opens negotiation with an insurer: a statement of how the incident happened and why their insured is responsible, the documented medical treatment and expenses, the effect on the claimant’s life and work, and a specific figure with a response deadline. Sending one does not extend any deadline. The two-year limitations period in Code of Civil Procedure section 335.1 keeps running while it sits on an adjuster’s desk.
We are B&D Injury Law Group, and our team handles injury claims across California and in Las Vegas, Nevada. The demand letter is the most misunderstood document in an injury claim, partly because template versions circulate widely and partly because people expect it to do something it cannot. Below: what actually belongs in one, the timing question that matters more than the wording, what a lowball response does and does not mean, and the statutory offer that changes the arithmetic once a case is filed.
What a Demand Letter Is, and What It Is Not
A demand letter is a private settlement communication from a claimant to the liability insurer for the person or business responsible. It has no procedural effect. It does not start a case, does not compel a response, and does not pause any clock.
That last point causes real damage. People send a demand, wait through months of adjuster silence and requests for more records, and discover the two-year deadline in Code of Civil Procedure section 335.1 has passed. Negotiation and the limitations period run in parallel, never in sequence. Where a public entity is involved, the Government Code section 911.2 written claim must be presented within six months, and a demand letter to an insurer is not a substitute for that claim.
What a demand letter does accomplish is set the frame. It is usually the first complete account of the claim the insurer receives, and the valuation it produces internally tends to anchor everything afterwards. A thin demand invites a thin reserve, and reserves are difficult to move later.
What Belongs In It
The parts that carry weight are the documented ones.
Liability comes first: a factual account of what happened, supported by the traffic collision report, photographs, scene evidence, witness statements, and any statutory provision the other party violated. Where a Vehicle Code section applies, cite it rather than describing it, and explain why the violation caused this harm rather than merely occurring near it.
Damages come next, split the way California splits them. Economic loss is the documented column: billed medical charges, the amounts actually paid, out-of-pocket costs, lost wages supported by an employer letter or pay records, and any future care or lost earning capacity supported by a treating physician rather than by assertion. Noneconomic loss is the part that requires writing rather than arithmetic, and it is where most demand letters are weakest.
The reason is that people describe their injuries instead of their lives. “Ongoing lumbar pain” is a medical phrase an adjuster reads a hundred times a week. What actually lands is specific and concrete: the job duties that had to be reassigned, the sport that stopped, the number of hours of sleep, the help now needed with a task that was routine before. Under CACI No. 3905A, the instruction a California jury receives on noneconomic damages, jurors are told that no fixed standard exists and that they must use their judgment to decide a reasonable amount based on the evidence and their common sense. Evidence of daily life is the only material that instruction gives them to work with.
Finally, a specific number and a reasonable response window. A demand without a figure invites delay.
| Section | What it should contain |
|---|---|
| Liability | Facts, report, photographs, witnesses, the statute violated and why it caused this harm |
| Medical treatment | Records and bills, chronologically, with charges and amounts paid distinguished |
| Wage loss | Employer verification or pay records, not an estimate |
| Future care | A treating physician’s stated opinion, not the claimant’s projection |
| Noneconomic loss | Specific, verifiable changes to daily life, work and activity |
| Demand | A stated figure and a response deadline |
The Timing Question
The most consequential decision is not what the letter says but when it goes out.
The general rule is not to send a demand before the medical picture is stable, the point clinicians often describe as maximum medical improvement. Settling earlier means valuing an injury whose trajectory is still unknown, and a settlement is final. If a shoulder needs surgery six months after a release is signed, that surgery is the claimant’s own expense.
The competing pressure is the limitations period. Where treatment is still ongoing as the two-year date approaches, the answer is generally to file suit and continue negotiating afterwards, not to rush a premature demand or let the deadline run. Filing does not end settlement discussions.
What a Low Response Actually Means
A first response well below the demand is routine and usually reflects something identifiable rather than bad faith.
The common drivers are a treatment gap in the records, a pre-existing condition in the same body part, an asserted share of comparative fault, billed charges the adjuster has discounted to what was actually paid or to a database figure, or an absence of evidence about daily-life impact. Each of those has a specific answer, and identifying which one is operating is more productive than restating the original number more loudly.
It is also worth understanding what recourse does not exist. In California, a third-party claimant has no private right of action against the other side’s insurer for unfair claims practices under Insurance Code section 790.03. The Supreme Court eliminated that avenue in Moradi-Shalal v. Fireman’s Fund Insurance Cos. (1988). Bad-faith duties run to the insurer’s own policyholder, which is why a first-party claim against your own carrier, for example under uninsured motorist coverage, is a different situation from a claim against the at-fault driver’s insurer.
Code of Civil Procedure Section 998 Changes the Arithmetic
Once a case is filed, California provides a statutory settlement mechanism with real consequences, and it is a substantially more powerful instrument than a demand letter.
Under Code of Civil Procedure section 998, either party may serve a written offer to compromise not less than 10 days before trial. The offer is deemed withdrawn, and cannot be given in evidence at trial, if it is not accepted within 30 days or before trial commences, whichever is earlier.
The consequences attach to refusing a reasonable offer. Under subdivision (c)(1), if a plaintiff refuses a defendant’s offer and then fails to obtain a more favorable judgment, the plaintiff cannot recover their post-offer costs and must pay the defendant’s costs from the time of the offer, and the court may additionally require payment of the defendant’s reasonable expert witness costs incurred after the offer. Under subdivision (d), where a defendant refuses a plaintiff’s offer and fails to obtain a more favorable judgment, the court may in its discretion require the defendant to pay a reasonable sum covering the plaintiff’s post-offer expert witness costs.
The practical effect is that a well-judged section 998 offer transfers risk. It is one of the few tools that makes continued refusal to settle expensive for the other side, and it is available only in litigation, which is part of why the pre-suit demand letter has the limits it does.
Frequently Asked Questions
Does sending a demand letter extend the deadline to file a lawsuit?
No. The two-year personal injury deadline in Code of Civil Procedure section 335.1 continues to run while a demand is pending, and negotiations do not toll it. Where a public entity is a defendant, the separate Government Code section 911.2 requirement to present a written claim within six months also continues to run, and a demand letter to an insurer does not satisfy it.
How long does an insurance company have to respond to a demand letter?
There is no statutory deadline for responding to a pre-suit demand from a third-party claimant. California regulations impose timeframes on insurers for acknowledging and acting on claims, but a claimant’s practical remedy for delay is to file suit rather than to wait, particularly as the limitations period approaches.
Should I write my own demand letter?
For a small claim with accepted liability and completed treatment, many people do so effectively. The difficulty in larger claims is not the writing but the valuation: future care, lost earning capacity and lien resolution determine the number, and a demand sent before the medical picture is stable locks in a figure based on an incomplete record.
Can I sue the other driver’s insurance company for handling my claim badly?
Generally not in California. Under Moradi-Shalal v. Fireman’s Fund Insurance Cos. (1988), there is no private right of action for a third-party claimant under Insurance Code section 790.03. Bad-faith duties are owed by an insurer to its own policyholder, so a claim against your own insurer, such as an uninsured motorist claim, stands on different footing.
What is a section 998 offer and how is it different from a demand letter?
A demand letter is an informal settlement communication with no procedural effect. A Code of Civil Procedure section 998 offer is a formal statutory offer available in litigation, served not less than 10 days before trial and deemed withdrawn if not accepted within 30 days or before trial. Refusing one and failing to do better at trial carries cost consequences under section 998: a plaintiff loses post-offer costs and pays the defendant’s costs, and on either side the court may order payment of the other party’s post-offer expert witness fees.
