A personal injury demand letter is the first formal move in settlement negotiations. You send it to the at-fault party’s insurance company — not the person who injured you — and it does two things: it establishes your version of events and the evidence that supports it, and it puts a specific dollar figure on the table. The insurer then has the option to pay, counter, or deny. How well the demand letter is constructed often determines which of those happens.
What Is a Personal Injury Demand Letter?
A demand letter is a written communication from you (or your attorney) to the at-fault party’s liability insurer stating the facts of the accident, documenting your injuries and losses, arguing why the insured is legally responsible, and demanding a specific settlement amount. It’s the opening position in a negotiation, not a court filing.
Sending a demand letter is typically the step that kicks off serious settlement discussions. Before it’s sent, you’re gathering medical records and building your case. After it goes out, the insurer is on the clock — most demand letters give the carrier 30 days to respond.
When to Send a Demand Letter
Timing matters more than most people realize. The right time to send a demand letter is after you’ve reached maximum medical improvement — the point where your doctor has a clear picture of your long-term prognosis. Sending before that point means demanding compensation for an injury that isn’t fully characterized yet. If your condition worsens after you settle, you generally can’t go back for more.
You also need to be aware of your state’s statute of limitations. Most personal injury claims must be filed in court within one to three years of the accident, depending on the state. A demand letter is a pre-litigation step, but if negotiations fail, you need enough time left on the clock to file a lawsuit. Most attorneys recommend sending demand letters well before the deadline — not in the final months.
What a Personal Injury Demand Letter Must Include
A complete demand letter is a documented case for your claim. Missing any of these elements gives the insurer room to minimize or dispute your demand:
- Your identification and the claim reference. Full name, contact information, date of accident, and any claim or policy number the insurer has already assigned to the case.
- A detailed account of the accident. What happened, when, where, and how. Be specific about the conditions and sequence of events. This is your narrative of liability, not a casual description.
- The liability argument. Why the other party is legally responsible. In a car accident case, this might cite the traffic violation or reckless driving that caused the crash. In a slip and fall, it might reference the property owner’s failure to maintain safe conditions. This section is where you establish that they owe you money.
- Your injuries and medical treatment. A complete chronological record of your injuries, every provider who treated you, and the full course of treatment to date. Attach supporting documentation: ER records, specialist notes, physical therapy records, imaging results, prescription history.
- Your documented damages. Every economic loss related to the accident. Medical bills (past and estimated future). Lost wages with a wage verification letter from your employer. Out-of-pocket expenses. Property damage repairs.
- Pain and suffering. Non-economic damages for the physical pain, emotional distress, and disruption to your daily life. This component typically represents a multiplier of your economic damages — insurers will negotiate hard on this figure.
- The demand amount. A specific dollar figure. Not a range — a number. The demand is the opening position, and insurers expect it to be higher than the final settlement. Set it high enough to give you negotiating room without being so inflated it isn’t credible.
- A response deadline. Typically 30 days. Stating a deadline signals that you’re organized and prepared to take further action if the insurer doesn’t respond.
Common Demand Letter Mistakes to Avoid
- Sending before maximum medical improvement. This is the most common mistake. Settling before your prognosis is clear means you might be accepting less than your future costs warrant.
- Undervaluing pain and suffering. Most people focus on the hard numbers (medical bills, lost wages) and lowball or omit the non-economic component. Pain and suffering is compensable and often represents the largest portion of a fair settlement.
- Missing documentation. A demand letter without attached supporting records is not a demand — it’s a request for the insurer to ask you more questions. Every claim in the letter needs documentation.
- Making statements that could hurt you. Anything you put in writing becomes part of the record. Avoid speculating about causation, admitting any fault, or describing your injuries in ways that could later be used to minimize them.
- Sending to the wrong party. You send the demand letter to the at-fault party’s insurance carrier — not to the person who injured you, not to your own insurer (unless it’s an uninsured motorist claim). Know who you’re addressing.
What Happens After the Demand Letter Goes Out
The insurer will investigate the claim: reviewing your documentation, potentially requesting an independent medical examination, and assessing the strength of their insured’s liability. Their response typically arrives within 30 days, though it can take longer in complex cases.
They’ll either accept your demand (uncommon at the opening position), issue a counteroffer (typical), or deny the claim. If they counter, negotiation begins. Most personal injury claims settle somewhere between the initial demand and the insurer’s first counter, through rounds of negotiation that can take weeks to months.
If the insurer refuses to offer reasonable value — or denies the claim outright — the next step is filing a lawsuit. A personal injury lawyer makes that transition seamless, because they’ve been building the litigation file since day one.
Why Working With a Lawyer Improves Outcomes
Demand letters written by attorneys settle for more than demand letters written by unrepresented claimants. The reasons are consistent: attorneys know what comparable cases produce in verdicts and settlements, they frame damages in language that resonates with adjusters, and they don’t make the factual or strategic errors that can undermine a demand.
The contingency fee structure means there’s no out-of-pocket cost for representation. Most personal injury attorneys will review your case for free and give you an honest assessment of whether a demand letter they write would be likely to produce a better result than one you write on your own. Understanding the full range of what personal injury settlements look like in your type of case is also something an attorney can provide, which gives you a basis for evaluating whether the insurer’s counter is reasonable.
Looking at what a realistic car accident settlement or similar injury case produces in your state gives you a benchmark — but an attorney who has tried and settled similar cases knows those ranges in a way that published averages can’t fully capture.
Frequently Asked Questions
Can I write a personal injury demand letter without a lawyer?
Yes. Nothing legally requires an attorney to write a demand letter. But the practical question is whether your unrepresented demand will produce a settlement that adequately covers your damages. Insurers deal with unrepresented claimants regularly, and their first offers to unrepresented people tend to be lower. Whether the difference in settlement value exceeds the attorney’s contingency fee is case-specific — but for injuries with real medical costs and lost wages, representation typically pays for itself.
What if the insurer ignores my demand letter?
No response within the stated deadline is a signal that the insurer doesn’t consider your claim a priority, or is testing whether you’ll follow up. Your options are to follow up with a letter asserting you’ll file suit, file a complaint with your state’s insurance commissioner, or consult an attorney and move toward litigation. Silence does not mean denial — but it does mean you need to take a next step.
How much should I demand in my demand letter?
The demand should be higher than what you’re actually willing to accept, to leave room for negotiation. A common approach is to total your documented economic damages (medical bills, lost wages, out-of-pocket costs) and add a multiple of that amount for pain and suffering — typically 1.5x to 3x for moderate injuries, higher for serious or permanent ones. However, the right number depends on your specific injury, how strong your liability case is, and what similar claims settle for in your jurisdiction. An attorney can give you a more precise range.
