A personal injury demand letter is the formal written proposal you send to the at-fault party’s insurance company explaining what happened, why they’re liable, and the dollar amount you’re asking for to settle the claim. It opens settlement negotiations and, if those fail, sets up the lawsuit that follows. The demand number anchors every offer and counteroffer after it, so the letter needs to be timed right, documented thoroughly, and calculated in a way an adjuster can follow.
When to Send It
Wait until your doctor says you’ve reached maximum medical improvement. That’s the point where further treatment is unlikely to produce significant additional recovery. It doesn’t mean you’re fully healed. It means your condition has plateaued enough that a physician can describe what treatment has cost, what future care you’ll need, and whether you’ll have lasting limitations. Send a demand before that, and you’re guessing at future medical costs instead of documenting them, which almost always means undervaluing the claim.
At the same time, keep your state’s statute of limitations in view. Personal injury filing deadlines fall between one and three years from the date of injury in most states. Sending a demand letter does not pause that clock. Neither does an active back-and-forth with an adjuster. If the deadline passes while you’re still negotiating, the insurer has no obligation to settle, and your right to sue is gone. Send the demand early enough that filing a lawsuit remains a real option if talks stall.
Evidence You Need Before Drafting
Adjusters are paid to find gaps. Every missing document is a reason to discount your number. Assemble the full file before you write.
- Police or incident reports from the agency that responded, including any preliminary assessment of fault.
- Every medical record and bill from the date of the accident forward: emergency room visits, imaging (MRIs or CT scans), surgeries, prescriptions, physical therapy. MRI scans alone can range from roughly $350 to $2,500 or more depending on the facility and body part, so itemized billing matters. Each bill should show provider, date of service, and amount charged.
- A treatment summary from your physician that connects your injuries to the accident. This is the document that ties the medical bills to the incident rather than to a pre-existing condition.
- Lost wage documentation: a signed letter from your employer confirming the dates you missed, your pay rate, and the total income lost. Pay stubs from before and after the accident back the number up.
- Photographs and video of the scene, vehicle or property damage, visible injuries, and your recovery. Timestamped images carry extra weight.
- Out-of-pocket expense receipts for anything the injury forced you to pay for, from prescription copays to help with housework you couldn’t do.
When you sign a medical records authorization, limit it to treatment related to the accident. Specify the date range and the injuries at issue. A broad authorization gives the insurance company access to your entire medical history, which they’ll comb through for pre-existing conditions to blame your symptoms on.
How to Calculate the Demand
The number has two parts: economic damages you can document with receipts, and non-economic damages for pain and disruption that don’t come with a price tag.
Economic Damages
Add up every verifiable financial loss. Medical bills are the largest line item for most claims, followed by lost wages. Include future medical costs if your doctor has recommended ongoing treatment or surgery. Property damage, like vehicle repair in a car accident, goes here too. This total is your floor, and it should be supported dollar-for-dollar.
Non-Economic Damages
Pain and suffering is harder to pin down. Adjusters generally use one of two approaches, and understanding both helps you justify your number.
The multiplier method takes your total economic damages and multiplies them by a factor, typically between 1.5 and 5. Minor soft tissue injuries sit at the low end; severe or permanent injuries push toward the high end. Economic damages of $20,000 at a multiplier of 2.5 would put non-economic damages at $50,000, for a total demand of $70,000.
The per diem method assigns a daily dollar value to your pain and multiplies it by the number of days you were affected. At $150 a day for a 200-day recovery, that’s $30,000 in pain and suffering. The method works when you can define a clear recovery period, and it struggles when injuries are permanent.
Neither is a legal formula. They’re negotiation frameworks. The demand should be high enough to leave room to move but grounded enough that an adjuster takes it seriously. A number pulled out of thin air invites the adjuster to do the same.
What Goes in the Letter
Adjusters review hundreds of these. Sticking to the standard structure makes it easier for them to process the claim and harder for them to ignore it.
Header and Identifying Information
Open with your name, address, phone, and email. Below that, list the adjuster’s name, the insurance company’s name and address, the claim number, and the date of loss. If you have an attorney, their contact information goes here instead of yours.
Statement of Facts
Describe what happened in plain, chronological order: date, time, location. Stay with what the evidence shows. “The other driver ran a red light and struck my vehicle in the intersection” is stronger than a paragraph of emotional language. Reference the police report where it supports your account.
Liability
Explain why the other party is responsible. No legal jargon needed. If a driver was texting, say so. If a store owner ignored a spill for hours, describe the evidence showing they knew about it. If there’s any argument you share some fault, don’t volunteer damaging admissions. Adjusters will try to assign you a percentage of blame to reduce what they owe, and anything you concede in writing can be used to justify a lower offer.
Injuries and Medical Treatment
Walk through your injuries and the treatment timeline. Start with the initial diagnosis, move through each phase of care, and end with your current condition. Use the language from your doctor’s records. If your physician noted a herniated disc at L4-L5, say that. Then explain in plain terms what it meant day to day: you couldn’t pick up your child, you couldn’t sit at your desk for more than twenty minutes, you missed your daughter’s soccer season.
Itemized Damages
List every economic loss with the amount and supporting document. A clean numbered list or table works well: emergency room visit, imaging, physical therapy sessions, lost wages at your hourly rate for the weeks you missed, then pain and suffering, then the total. Showing your math signals that the demand is calculated, not invented.
The Demand and Deadline
State the total you’re requesting and set a response deadline. Thirty days is standard. It gives the adjuster enough time to review your documentation without letting the claim gather dust. Close by noting that the letter is a settlement offer and that you intend to pursue legal action if a fair resolution isn’t reached.
Under Federal Rule of Evidence 408, settlement offers and statements made during negotiations generally cannot be used as evidence of liability if the case goes to trial.1Legal Information Institute. Rule 408 Compromise Offers and Negotiations The demand amount you propose won’t be held against you in court, which is what lets both sides negotiate honestly.
Sending the Package
Address the letter to the specific claims adjuster assigned to your file, not to the insurance company’s general mailroom. Call the insurer and ask for the adjuster’s name and direct mailing address if you don’t already have them. A letter sent to a general address can sit in a processing queue for weeks.
Send it by certified mail with return receipt requested. The signed receipt gives you a dated record showing when the insurer received the demand, which matters if there’s ever a dispute about whether they got it or when the response clock started. Include the letter and a complete, organized set of supporting documents: medical records, bills, the police report, wage verification, photographs, and anything else referenced in the letter. An adjuster chasing missing records will take longer to respond and may use the gaps as a reason to undervalue the claim.
What Happens After You Send It
Once the demand package arrives, the adjuster opens a review. Most responses come within a few weeks to a couple of months, though complex claims can take longer. During that window the adjuster is verifying your medical bills, checking them against the policy limits, and running their own damage calculations.
The Three Typical Responses
Full acceptance of your demand is rare on the first pass, but it happens, particularly with smaller claims backed by clean documentation. More commonly, the adjuster sends a counteroffer proposing a lower amount, which kicks off a back-and-forth that may take several rounds. The third possibility is a denial, where the insurer argues there’s no liability or that your evidence doesn’t support the claim. A denial must include the insurer’s reasoning.2HealthCare.gov.

If the Insurer Goes Silent
Sometimes there’s no response at all. If your deadline passes, follow up with a call or email to confirm receipt. If the silence continues, a second letter, often called a final demand, puts the insurer on notice that you intend to file suit within a set number of days. Filing the lawsuit itself frequently prompts a response. Insurers that ignored a letter tend to take a court summons more seriously.
Negotiating the Counteroffer
A low counteroffer isn’t a rejection. It’s the start of a negotiation. Respond in writing, pointing to the documentation they underweighted: a future surgery your doctor recommended, lost earning capacity if you can’t return to the same job, the severity of pain their valuation seems to ignore. Each round should narrow the gap. When numbers stay far apart and talks stall, filing suit becomes the practical next step.
Liens That Can Reduce Your Settlement
If any insurer or government program paid for your accident-related care, they likely have a legal right to be repaid from your settlement. This catches people off guard at the end of the case, so plan for it before you agree on a number.
Medicare payments for accident-related treatment are considered conditional, and federal law requires reimbursement from your settlement, judgment, or award.3Office of the Law Revision Counsel. 42 US Code 1395y – Exclusions From Coverage and Medicare as Secondary Payer Repayment is due within 60 days of settlement, with interest if you’re late. Before settling, request a conditional payment statement from the Benefits Coordination and Recovery Center so you know what’s owed.4Centers for Medicare & Medicaid Services. Medicare’s Recovery Process
Private health insurance policies usually contain subrogation clauses giving the insurer the right to recover what it paid for your accident-related care. Employer-sponsored plans governed by federal law are especially aggressive about enforcement and often claim first-priority lien status on settlement proceeds. Ignoring a valid subrogation lien doesn’t make it go away. The insurer can sue you for reimbursement years after settlement. Identify every insurer that paid for your treatment, get the lien amounts in writing, and know that in some cases those amounts are negotiable, particularly when the settlement doesn’t fully cover your losses.
Signing the Settlement Release
If you reach a number, the insurance company will send a release document to sign before cutting the check. Read it carefully. A general release means you’re giving up the right to seek any additional compensation from the at-fault party for anything related to the accident. Once signed, the case is over permanently, even if your condition worsens six months later or you discover medical problems you didn’t know about at settlement. This is why waiting for maximum medical improvement matters so much at the front end. Settle before your doctors have the full picture, and you’re locked into a number that may not cover what’s coming.
The release will usually require you to resolve any outstanding medical liens from the settlement funds. On a $50,000 settlement with $8,000 owed to Medicare, $16,500 in attorney’s fees, and $1,500 in costs, the money reaching you is $24,000. Run those numbers before agreeing to a settlement amount, not after.
