How a Personal Injury Demand Letter Works | Marathon Law Group

If you’ve been injured in an accident caused by someone else’s negligence, one of the most important steps in resolving your personal injury claim is sending a demand letter to the at-fault party’s insurance company. A personal injury demand letter formally notifies the insurer of your claim, summarizes the evidence of liability, and demands a specific dollar amount as compensation for your injuries and losses.

At Marathon Law Group, our Las Vegas personal injury attorneys guide clients through every step of the claims process — including crafting powerful, persuasive demand letters that set the stage for maximum compensation. This guide explains what a demand letter is, what it should include, and how the process works.

What Is a Personal Injury Demand Letter?

A demand letter is a written document sent to the insurance company (or the at-fault party directly) that outlines your claim and demands compensation. It is typically sent after you have completed medical treatment — or reached maximum medical improvement (MMI) — so that the full extent of your injuries and costs are known.

The demand letter is one of the most critical documents in your personal injury case. It sets the tone of negotiations, establishes the value of your claim, and gives the insurance company an opportunity to settle before litigation. A well-drafted demand letter can often result in a fair settlement without ever filing a lawsuit.

What Should a Personal Injury Demand Letter Include?

While every case is different, a strong personal injury demand letter typically includes the following elements:

1. Introduction and Summary of the Accident

The letter opens with a clear statement of who you are, the date and location of the accident, how it occurred, and who was at fault. This section should be factual, concise, and supported by the evidence you’ve gathered — such as the police report, witness statements, and photographs.

2. Liability Argument

A demand letter must clearly establish why the other party is legally responsible for your injuries. This section lays out the legal theory of liability — whether negligence, recklessness, or another legal standard — and cites the specific facts and evidence that support your position.

3. Description of Your Injuries

The letter must describe your injuries in detail — the diagnosis, the treatment you received, the doctors and facilities involved, the duration of your recovery, and any permanent effects. Medical records, imaging reports, and physician notes are typically attached as supporting exhibits.

4. Medical Expenses and Future Medical Costs

All past medical bills related to the accident should be itemized and totaled. If you will require ongoing or future medical care — such as physical therapy, surgeries, or long-term medication — those projected costs should also be documented and included with supporting expert opinions where appropriate.

5. Lost Wages and Lost Earning Capacity

If the accident caused you to miss work, you are entitled to compensation for your lost income. If your injuries permanently affect your ability to work or earn at the same level as before, your claim should include the estimated value of your lost future earning capacity, typically supported by vocational and economic expert analysis.

6. Pain and Suffering

Beyond economic losses, you are entitled to compensation for the physical pain, emotional distress, anxiety, depression, and reduction in quality of life caused by the accident and your injuries. Calculating pain and suffering damages requires experience and skill — insurance companies will try to minimize this figure, and a skilled attorney knows how to document and argue for its true value.

7. Property Damage

If your vehicle or other personal property was damaged in the accident, the repair costs or fair market value of the property (if totaled) should be included in the demand letter.

8. The Settlement Demand

The letter concludes with a specific demand — a dollar amount that you are requesting to settle the claim. This figure should be calculated to cover all of your current and future damages while leaving room for negotiation. Setting the demand too low can undermine your recovery; setting it too high without support can delay resolution.

What Happens After You Send the Demand Letter?

After the insurance company receives your demand letter, they typically have 30 days to respond — though Nevada law requires insurers to acknowledge receipt within 10 working days and complete their investigation within 30 days (NRS 686A.310). The insurer may respond with:

  • An acceptance — the insurer agrees to pay the demanded amount, and settlement proceeds.
  • A counteroffer — the insurer offers a lower amount, and negotiation begins.
  • A denial — the insurer disputes liability or the value of the claim, which may lead to litigation.

Most personal injury claims settle through negotiation without going to trial. Your attorney’s skill in the negotiation process — and their willingness to file suit if necessary — is a key factor in reaching a fair outcome.

Common Mistakes to Avoid in a Demand Letter

A poorly written demand letter can actually hurt your case. Common mistakes include:

  • Sending the letter before treatment is complete and full damages are known
  • Using overly emotional language that undermines credibility
  • Making unsupported or exaggerated damage claims
  • Forgetting to attach key supporting documents (medical records, bills, police report)
  • Setting a demand that is too low and cannot be effectively negotiated upward
  • Failing to include a clear deadline for the insurer to respond

Working with an experienced personal injury attorney ensures your demand letter is professional, well-supported, and strategically positioned to maximize your recovery.
