What Is a Demand Letter in a Personal Injury Case?

In most personal injury cases, the formal claims process begins not with a lawsuit but with a document called a demand letter. This letter, typically sent to the at-fault party's insurance company, is a comprehensive written statement that summarizes your case — the accident, your injuries, your damages, and the amount of money you are seeking to resolve the claim. It is one of the most important documents in any injury case and sets the tone for all negotiations that follow.

The demand letter serves several purposes at once. It puts the insurer on notice of your claim, demonstrates that you are organized and serious about pursuing compensation, and provides the documentation the adjuster needs to evaluate your damages. A well-crafted demand letter can accelerate the settlement process and lead to a fair resolution without the need for a lawsuit. A poorly constructed one — vague, incomplete, or poorly timed — can give the insurer grounds to undervalue or reject the claim.

Timing matters significantly. Most attorneys advise waiting until you have reached maximum medical improvement (MMI) before sending a demand letter. Sending it too early, before your medical treatment is complete, means you do not yet know the full extent of your medical bills or the lasting impact of your injuries. It also leaves you in a weak negotiating position, as you will have already disclosed your demand before understanding the true value of your claim.

A strong demand letter includes several key components. First is a detailed factual account of how the accident occurred, presented from your perspective. This section should be clear, specific, and consistent with the official accident report. Second is a description of the injuries you sustained, supported by medical records, imaging results, and physician notes. The more objective and documented your injuries are, the more credibility your demand carries.

The letter should then detail all of your economic damages. This includes every medical bill — emergency room, hospitalizations, specialist visits, physical therapy, medications, and any anticipated future treatment costs. Lost wages must be documented with pay stubs or employer letters showing the time you missed work and the income you lost as a result. Any other out-of-pocket expenses caused by the accident, such as transportation to medical appointments, home modifications, or hired help for tasks you can no longer perform, should be itemized.

After economic damages, the letter addresses non-economic damages — pain and suffering, emotional distress, loss of enjoyment of life, and similar impacts. This section is more subjective but should be supported by a narrative that describes how the injuries have actually affected your daily life, relationships, and well-being. Specific examples are always more persuasive than general statements.

The letter concludes with your settlement demand — the specific dollar amount you are requesting. This number should be based on your documented damages plus a reasonable amount for non-economic harm, and it should generally be set higher than your true target figure to leave room for negotiation. Including a deadline for the insurer's response — typically 30 days — adds structure to the process and signals that you are prepared to take further action if needed.

After sending the letter, the insurer will review it and either accept your demand, make a counteroffer, or deny the claim. The counteroffer begins a negotiation phase that may involve several back-and-forth exchanges before a settlement is reached. If negotiations fail, the next step is filing a lawsuit.
