The demand letter is the document that turns a pile of medical bills and bad memories into a number an insurer has to answer. It is the formal opening move in settlement negotiations: a written summary of what happened, who is responsible, what it cost you, and how much you expect to be paid to resolve the claim. Written well, it frames the entire conversation in your favor. Written poorly — too early, too low, or with a fact the adjuster can attack — it can quietly cost you thousands. This guide walks through what goes in a demand letter, how to set and defend the number, what to attach, and how to handle the counteroffer that almost always follows.
A demand letter is a persuasive but factual document sent to the at-fault party's liability insurer (occasionally to the at-fault person directly). It packages your claim, states a specific dollar demand, and sets a deadline for the insurer to respond. It is not a lawsuit, but it signals you are organized, serious, and prepared to escalate.
Timing matters more than most people realize. The single most important rule: do not send a demand until you have reached maximum medical improvement (MMI) — the point at which your doctors say you have recovered as much as you reasonably will, or your condition has stabilized. Demanding before MMI means guessing at your future medical needs, and because a settlement is final, you cannot reopen the claim if you later need surgery or ongoing therapy. The exception is when a legal deadline forces your hand. Every state's statute of limitations sets a hard backstop — commonly two or three years from the date of injury, though it varies — after which you generally lose the right to sue at all. If that clock is running out, you may need to act (and possibly file suit) before reaching MMI. Confirm your state's exact limitations period; the rules are set by state statute, and your state bar association can point you to them.
A demand letter should read as a logical argument that builds from facts to fault to harm to money. The table below maps the standard sections and what each one needs to accomplish.
| Section | What it includes | Goal |
|---|---|---|
| Heading & reference | Date, claim number, your name, the insured's name, date of loss | Lets the adjuster file and locate it instantly |
| Facts of the accident | A neutral, chronological account of what happened — date, time, location, conditions | Establishes the story in your words first |
| Liability argument | Why the other party is legally at fault, citing the police report, traffic laws, or witness statements | Removes doubt about who pays |
| Injuries & treatment | Diagnoses, the course of care from ER to discharge, and current/lasting limitations | Connects the crash to real harm |
| Economic damages | An itemized list of medical bills, lost wages, and out-of-pocket costs, with a total | Anchors the claim in hard numbers |
| Non-economic damages | A justified explanation of pain, suffering, and reduced quality of life | Supports value beyond receipts |
| The demand | A single, specific dollar figure | Sets the negotiation anchor |
| Deadline & closing | A response window (commonly 21–30 days) and your contact details | Creates momentum and a record |
Each section feeds the next. The facts make liability obvious; liability makes the injuries the insurer's problem; the injuries justify the damages; the damages justify the demand.
Your demand should be anchored high but defensible — high enough to leave room for the inevitable downward negotiation, grounded enough that you can explain every dollar. Start with your economic damages: add up every medical bill, your documented lost wages, and out-of-pocket costs (mileage to appointments, medical equipment, hired help). These are objective and hard to argue with.
Then value your non-economic damages. The most common approach in negotiation is the multiplier method: multiply your economic damages by a factor (often 1.5 to 5) keyed to how severe, permanent, and disruptive the injury was. A moderate injury with full recovery might justify a 2x or 3x multiplier; serious, permanent injuries support higher. For the mechanics and a worked example, see our companion guide on how settlements are calculated. Whatever multiplier you choose, be ready to defend it with the medical record — a high number with no documentation behind it simply invites the adjuster to ignore it.
Set your stated demand somewhat above your honest target so there is room to concede toward a figure you would actually accept. Do not inflate it past the point you can justify with paper; an adjuster who spots an indefensible number stops taking the whole letter seriously.
The demand is the argument; the attachments are the evidence. Send copies (never originals) of:
Write like a calm, organized professional, not an angry victim. The letter should be firm and confident without insults, threats, or emotional language. Use plain, specific facts; let the evidence carry the outrage. Keep it well-organized with clear headings, correct names and claim numbers, and no typos — a sloppy letter signals an unprepared claimant. Remember the adjuster is the audience: you are giving a professional a clean, persuasive file they can take to a supervisor to justify paying you.
A workable skeleton, with notes on what each line is doing:
Expect the first reply to be a low counteroffer — that is standard practice, not an insult. Do not accept it reflexively, and do not respond emotionally. Instead, ask the adjuster to explain, in writing, the basis for their figure, then respond with a measured counter that points back to your documentation. Negotiation usually moves in several rounds toward a middle figure. If an insurer drags its feet, misrepresents your coverage, or refuses to give a reasonable basis for a denial, those behaviors may run afoul of your state department of insurance's unfair claims settlement practices rules — most states have adopted standards modeled on the National Association of Insurance Commissioners (NAIC) framework, and your department of insurance accepts complaints. Knowing those rules exist can itself sharpen a stalled negotiation.
You can handle a small, clear-liability claim yourself. But consider an attorney when injuries are serious or permanent, when fault is disputed, when multiple parties or policies are involved, when the insurer denies the claim or stalls, or when the statute of limitations is approaching. Most personal injury attorneys offer free consultations and work on contingency. Your state bar association runs a lawyer referral service and lets you confirm an attorney is licensed and in good standing.
Treat the demand as a legal record. Keep a complete copy of the letter and every attachment, and send it by a trackable method — certified mail with return receipt, or a courier with delivery confirmation — so you have proof of what you sent and when. That timestamp matters if the claim later moves toward litigation or a limitations-period dispute.
No. You can write and send one yourself, and many people do for minor, clear-fault claims. But for serious injuries, disputed liability, or a stalling insurer, a lawyer's demand often carries more weight and helps avoid mistakes that reduce your recovery. Most offer free consultations through your state bar's referral service.
A response deadline of about 21 to 30 days is typical and reasonable. It creates momentum without looking aggressive. Be aware the deadline is a negotiating device, not a legal one — the true hard deadline is your state's statute of limitations.
That is normal. Treat the low counter as an opening position, ask for the reasoning in writing, and respond with a documented counter rather than accepting or walking away. Negotiation usually takes several rounds.
It can if it contains errors, exaggerations, or admissions of fault, because the insurer can use those against you. Stick to documented facts, avoid speculating about your own responsibility, and keep a copy of exactly what you sent.
