What Is a Demand Letter in a Personal Injury Case?
David J. Muñoz | September 1, 2026 | Personal Injury
A demand letter in a personal injury case is a formal request for compensation sent to an insurance company or at-fault party. It typically explains how the accident happened, why the other party is responsible, the injuries and losses you suffered, and the amount you’re seeking to settle your case.
A demand letter often marks the beginning of serious settlement negotiations and gives the insurer an opportunity to resolve the claim without going to court.
What Is the Purpose of a Personal Injury Demand Letter?
The purpose of a demand letter is to present your personal injury claim to the insurance company and request an appropriate settlement. Rather than simply stating how much money you want, a well-supported demand explains why you are entitled to compensation and provides evidence of your losses.
A demand letter can also establish a starting point for negotiations. The insurance company can review the information and decide whether to accept the demand, make a counteroffer, request additional documentation, or dispute the claim.
What Should a Personal Injury Demand Letter Include?
A demand letter should provide enough information and supporting evidence for the insurance company to evaluate the claim.
Depending on the circumstances, it may include:
- A description of the accident and how it occurred
- An explanation of why the other party is liable
- A description of your injuries
- Medical records and bills
- Documentation of lost wages or income
- Information about pain and suffering and other losses
- Supporting evidence, such as photographs or reports
- The amount requested to settle the claim
The contents will vary from case to case. More serious or complicated injuries may require considerably more documentation to demonstrate the full extent of the injured person’s losses.
When Is a Demand Letter Sent?
A personal injury demand letter is generally sent after enough information is available to reasonably evaluate the claim. Sending one too early can make it difficult to account for ongoing medical treatment, future care, or other losses that are not yet known.
For example, someone who is still receiving treatment may not yet know whether an injury will fully heal or result in lasting limitations. Waiting until the nature and extent of the damages are better understood can make it easier to prepare a demand that reflects both current and expected losses.
However, waiting to send a demand letter does not extend any applicable deadline for filing a personal injury lawsuit.
What Happens After a Demand Letter Is Sent?
After receiving a demand letter, the insurance company will typically review the claim and supporting documentation before responding.
The insurer may:
- Accept the settlement demand
- Make a counteroffer
- Ask for additional information or records
- Dispute liability or certain damages
- Reject the demand
A counteroffer does not necessarily mean negotiations are over. The parties may exchange multiple offers before reaching an agreement.
If a settlement cannot be reached, the injured person may decide to pursue compensation through a personal injury lawsuit.
How Is the Settlement Amount in a Demand Letter Determined?
The amount demanded should reflect the circumstances of the individual case rather than an arbitrary figure. Factors such as the severity of the injuries, medical expenses, lost income, future treatment, pain and suffering, available insurance coverage, and the strength of the evidence can all affect the value of a personal injury claim.
Demanding too little could undervalue significant losses, while demanding an amount that cannot be supported by the facts and evidence may make productive negotiations more difficult.

Frequently Asked Questions
Is a Demand Letter the Same as Filing a Lawsuit?
No. A demand letter is generally part of the settlement process and does not itself begin a lawsuit. It gives the other party or insurance company an opportunity to resolve the claim without litigation.
How Long Does an Insurance Company Have to Respond to a Demand Letter?
There is no universal response period for every personal injury demand letter. The appropriate timeline can depend on the circumstances, applicable law, and any deadline included in the demand.
Does Sending a Demand Letter Guarantee a Settlement?
No. An insurance company may accept the demand, make a counteroffer, dispute the claim, or refuse to settle. If negotiations are unsuccessful, filing a lawsuit may be an option.
