The Personal Injury Demand Letter is the single most important document in a pre-litigation car accident claim. It opens formal settlement negotiations with the at-fault driver's liability insurance carrier, sets the ceiling for the value of the claim, and creates a written record that will follow the file through settlement, mediation, or trial.
A well-drafted demand letter tells a story: the crash, the injuries, the treatment, the disruption to your life, and the dollar amount that makes you whole. Adjusters read hundreds of demand letters each month; the ones that get paid quickly are specific, chronological, cite medical documentation by page number, and demand a total that the adjuster's reserve authority can meet without escalating to a supervisor.
Send the letter only after all treatment has concluded and you have reached what physicians call 'maximum medical improvement' (MMI). Sending too early — while you are still treating — signals inexperience and gives the adjuster a discount. Sending after the statute of limitations has run signals nothing at all; the claim is dead.
When to use this tool
- ▸Treatment is complete and you have your final medical bills, records, and lost-wage documentation.
- ▸The at-fault driver has been identified and their insurance carrier has an open claim number.
- ▸You are within the applicable state statute of limitations, with at least four months of runway before it expires.
- ▸You have decided to negotiate directly with the insurer rather than immediately file suit.
- ▸You want to preserve leverage: an unanswered or under-responded demand becomes exhibit A when you retain counsel and sue.
How this letter is structured
The template follows the industry-standard six-part structure adjusters expect: (1) identification of parties and claim number; (2) statement of liability facts describing exactly how the crash happened; (3) description of injuries and treatment course, tied to specific medical providers; (4) itemization of economic damages (medical bills, lost wages, property damage); (5) pain-and-suffering discussion with reference to the multiplier method; (6) total demand and response deadline.
Attach — do not merely reference — the police report, all medical records, all itemized medical bills, wage-loss documentation from your employer, and photographs. Adjusters value what is in the file over what is described in prose. A complete demand package moves through the reserve review process in two to four weeks; an incomplete package sits.
Set a firm response deadline (typically 30 days from receipt) and follow up in writing if you do not receive a substantive response. Do not, however, threaten litigation you are not prepared to file. Empty threats train the adjuster to discount your file.
Key legal terms
- Maximum Medical Improvement (MMI)
- The point at which further treatment is not expected to improve the injury; the appropriate moment to send the demand.
- Reserve
- The dollar amount the insurance carrier internally sets aside for the claim; adjusters have authority to settle up to the reserve without supervisor approval.
- Full and final release
- The settlement contract that ends the claim forever. Review carefully for language releasing UM/UIM, MedPay, or PIP claims you may need to preserve.
- Lien
- The right of a health insurer, hospital, or MedPay carrier to be reimbursed from the settlement.
- Bad faith
- An insurer's unreasonable refusal to settle a clear-liability claim within policy limits; exposes the insurer to extra-contractual damages.
Frequently asked questions
How much should I demand?
Demand higher than the multiplier-method estimate — commonly 1.3× to 1.5× the calculator output. Never anchor at your true bottom line; leave room to negotiate down while landing where you actually want to be.
How long until the insurer responds?
Adjusters typically acknowledge receipt within 5–10 business days and provide a substantive response — offer, counter, or request for more documentation — within 30 days. If nothing comes in 45 days, follow up in writing and cc the state insurance commissioner if silence persists.
Do I have to accept the first offer?
No. The first offer is nearly always a lowball. Counter with a modest reduction from your demand and demonstrate you understand the file's weaknesses; a two-to-four-round negotiation is normal.
Should I send the letter certified mail?
Yes. Certified mail with return receipt establishes delivery date, which starts the response clock and creates evidence of good-faith negotiation attempts if you later file suit.
What if the at-fault driver has minimal coverage?
Include a demand for policy limits and cite the state's bad-faith doctrine. If the carrier fails to tender limits on a clear-liability claim exceeding those limits, you may later pursue the excess judgment directly against the carrier.
This template generates a starting draft; it is not legal advice and does not replace representation by a personal injury attorney. On serious-injury claims, wrongful death, or cases involving disputed liability, retain counsel licensed in the state where the accident occurred before sending any demand.
