What Is a Personal Injury Demand Letter?
A personal injury demand letter is the document that formally puts a California injury claim on the table. It is sent to the responsible party's insurance carrier and asks the carrier to compensate the claimant for what the incident caused. A well-built demand sets the tone for negotiation, anchors the discussion of value, and signals whether the claim is ready for serious resolution — or for litigation if it is not. This guide explains what a demand letter is, what it should include, what happens after it is sent, why carriers delay or reduce offers, and when to request a claim review.

If a demand has been sent on your behalf, or you are about to respond to one, get a free claim review. We can explain what the demand should contain, what the response actually means, and what your realistic next step looks like.
What Is a Personal Injury Demand Letter?
A personal injury demand letter is a written request to the at-fault party's insurance carrier (and sometimes to the claimant's own UM/UIM carrier when applicable) asking the carrier to pay a specific amount to resolve the claim. It is the formal start of meaningful settlement negotiation. It is not a lawsuit. It does not require the carrier to do anything by a particular date — but a well-built demand makes it much harder for a carrier to dismiss the claim with a low number.
A demand letter usually attaches the evidence the carrier needs to evaluate the claim: liability documentation, medical records, bills, wage loss support, and any expert input.
What Should Be Included in a Demand Letter?
A complete California personal injury demand letter typically includes:
- Facts of the incident. Clear narrative of how the injury happened — date, location, parties, mechanism.
- Liability analysis. Why the at-fault party is legally responsible, including statutes, regulations, and the police or incident report.
- Description of injuries. Diagnoses, symptoms, treatment history, impairment, and any permanent effects.
- Treatment chronology. A medical timeline showing the care received and how it relates to the incident.
- Medical bills. Itemized past medical expenses, with totals.
- Future medical care. Anticipated future surgery, injections, therapy, equipment, or long-term needs — supported by treating physician input where available.
- Lost wages. Time missed from work with employer letters, pay stubs, and tax records.
- Lost earning capacity. If the injury affects future earnings.
- Pain and suffering. Plain-English description of how the injury has affected daily life.
- Damages model. A coherent build-up of the demand amount, not just a number.
- Settlement demand. A specific dollar figure.
- Time period for response. Often 30 to 60 days — not legally binding, but it sets pace.
- Exhibits. Records, bills, photos, witness statements, expert reports, wage documentation.
Why Demand Letters Matter in Injury Claims
- They anchor the negotiation. The first credible number in the room shapes the rest of the conversation.
- They give the carrier the documents needed to evaluate the file at higher authority levels.
- They communicate readiness. Carriers respond differently to demands that look trial-ready.
- They protect a future bad-faith record if the carrier ignores or undervalues a well-supported claim.
- They give the claimant a clear written record of what is being asked for and why.
What Happens After a Demand Letter Is Sent?
Common outcomes after a demand goes out:
- Acknowledgment. The carrier confirms receipt and assigns or reassigns an adjuster.
- Records requests. The carrier may request additional records, an updated treatment summary, or signed authorizations.
- Offer. The carrier responds with an initial settlement offer.
- Counter / negotiation. The claimant counters; the carrier responds. This may continue over several rounds.
- Mediation. If pre-suit negotiation stalls, sometimes a pre-litigation mediation is scheduled.
- Lawsuit. If the carrier will not move to a fair number, a complaint is filed before the statute of limitations expires.
- Continued negotiation in litigation. Filing a lawsuit does not stop settlement talks. Most filed cases still resolve.
How Long Does the Insurance Company Have to Respond?
There is no fixed legal deadline for the carrier to respond to a pre-suit demand in California. Many carriers respond within 30 to 90 days. Some respond faster on liability-clear, fully-documented cases. Some sit on complex demands while moving the file up the authority chain. If the carrier goes silent for an unreasonable period, the next step is usually written follow-up, escalation, or filing suit before the statute of limitations expires.

Why Insurance Companies Delay or Reduce Offers
Delay and discount are standard parts of the playbook. Common patterns:
- Waiting until the statute of limitations is close, then putting pressure on.
- Pointing to "treatment gaps" to argue injuries were not as serious as claimed.
- Calling crashes "low impact" to discount injury (when insurance calls it "low impact").
- Labeling injuries "soft tissue" regardless of imaging (when insurance says injuries are "minor").
- Disputing comparative fault to reduce value.
- Requesting recorded statements that lock claimants into early, incomplete accounts (should you give a recorded statement?).
- Sending broad releases bundled with relatively low offers.
- Hiding behind "policy limits" without proof.
None of these are illegal. They are part of how high-volume claim files are managed. A well-documented demand, timely responses, and credible willingness to file suit are how these patterns are countered. See insurance company tactics in personal injury and responding to a lowball offer.
Mistakes That Can Lower Claim Value
- Sending a demand before medical treatment has plateaued.
- Omitting future medical care, lost earning capacity, or pain and suffering.
- Failing to identify all available insurance layers (umbrella, employer, UM/UIM).
- Including only a number without a documented damages model.
- Sending a demand without authority backing — an unprepared file that will not survive scrutiny.
- Accepting the first counter without negotiation.
- Signing a release without reviewing its scope.
- Missing the statute of limitations.
Get a Free Claim Review Before Responding
If you have received a settlement response — whether it is an offer, a denial, or silence — have it reviewed before you reply. A short review is free.
When to Ask for Legal Review
It often makes sense to have a lawyer or neutral reviewer look at a California injury claim before sending a demand letter — or before accepting the carrier's response. A claim review is especially worth it if:
- You drafted a demand yourself and want a sanity check before sending.
- A lawyer sent a demand on your behalf and you do not understand the response.
- You have been told the demand is "weak" because of treatment gaps or low property damage.
- The offer feels low but you do not have a basis to argue.
- You think the case may need to be filed but no one has explained why.
- You want a second opinion on your injury claim.
Demand Letters in Practice: A Realistic Arc
A typical California pre-suit timeline:
- Month 0: Incident, treatment begins.
- Months 0–3: Investigation, evidence preservation, opening claims with carriers, beginning of medical care.
- Months 3–12+: Treatment continues to plateau. Records and bills are collected.
- Plateau: Demand letter is prepared with full documentation.
- 30–90 days after demand: Carrier responds with offer, request for more documents, or denial.
- Negotiation: 1–3 rounds of counter-offers, sometimes more.
- Resolution or filing: Settlement reached, or lawsuit filed before the statute deadline.
Cases with surgery, contested liability, or commercial defendants often run longer. Cases involving public entities (cities, transit, public hospitals) require a short, written government claim within months of the incident — missing that deadline can permanently bar the claim.
Frequently Asked Questions
What is a personal injury demand letter?
A written request to the responsible party's insurance carrier asking for compensation for an injury, supported by liability and damages documentation, and stating a specific demand amount.
Who sends the demand letter?
Usually the claimant's attorney, though a claimant can send one without a lawyer. It typically goes to the at-fault party's liability insurer.
How long does insurance take to respond?
No fixed deadline. Many carriers respond in 30 to 90 days. Complex cases or large demands can take longer.
What happens if the insurance company rejects the demand?
Negotiation continues. Counter-offers, additional documentation, and sometimes mediation follow. If no fair resolution is reached, the claimant can file a lawsuit before the statute of limitations expires.
Can a demand letter affect settlement value?
Yes. A well-prepared demand with strong liability proof and complete damages documentation often produces a stronger first offer. A thin or premature demand can anchor the case low.
