What Is a Demand Letter in a Personal Injury Case?

What Is a Demand Letter?

A demand letter is a formal written document sent by your attorney to the at-fault party's insurance company. It outlines the facts of your accident, describes your injuries and medical treatment, details all financial losses, and states the total compensation being demanded. The demand letter is the opening move in settlement negotiations and is one of the most important documents in a personal injury case.

Think of the demand letter as your attorney's best argument for why the insurance company should pay you a specific amount. It is backed by evidence: medical records, bills, expert opinions, wage loss documentation, and photographs. A well-crafted demand letter from an experienced attorney can be the difference between a lowball offer and a fair settlement.

What Does a Demand Letter Include?

A thorough personal injury demand letter typically contains the following sections:

1. Statement of facts: A detailed narrative of how the accident occurred, who was at fault, and the evidence supporting liability (police reports, witness statements, photographs, video footage).
2. Description of injuries: A medical summary of every injury you sustained, the treatment you received, and your current condition. This section references your medical records and may include opinions from treating physicians or medical experts.
3. Medical expenses: An itemized accounting of all medical costs, including emergency care, hospitalization, surgery, physical therapy, prescription medications, medical equipment, and estimated future medical expenses.
4. Lost wages and earning capacity: Documentation of income lost due to missed work, reduced hours, or diminished ability to earn in the future. Supported by employer verification and, in serious cases, vocational expert opinions.
5. Pain and suffering: A description of the physical pain, emotional distress, loss of enjoyment of life, and other non-economic damages you have experienced. This section is narrative and personal, explaining how the injury has changed your daily life.
6. Total demand amount: The specific dollar figure being demanded, along with the reasoning for how that number was calculated.
7. Deadline to respond: A timeframe (typically 30 days) for the insurance company to respond with a counteroffer or acceptance.

When Is a Demand Letter Sent?

Your attorney will typically send the demand letter after you have reached maximum medical improvement (MMI). MMI is the point where your doctors determine your condition has stabilized. Sending the demand letter before MMI is risky because the full extent of your injuries and future medical needs is not yet known, which often leads to undervaluing the case.

In most personal injury cases, the demand letter is sent 6 to 18 months after the accident, depending on the severity of injuries and the length of medical treatment. Cases involving surgery, chronic pain, or permanent disability tend to take longer because the medical picture needs to be complete.

Who Writes the Demand Letter?

Your personal injury attorney writes the demand letter. While it is possible to write one yourself, there are significant risks in doing so. An attorney understands how insurance adjusters evaluate claims, what evidence to emphasize, how to calculate non-economic damages, and what legal theories strengthen your position.

Insurance companies treat demand letters from attorneys differently than letters from unrepresented claimants. Research consistently shows that injury victims represented by attorneys receive significantly higher settlements. For guidance on choosing the right attorney for your case, see our guide.

What Happens After the Demand Letter Is Sent?

After the insurance company receives the demand letter, the process typically follows this sequence:

1. Acknowledgment: The insurer confirms receipt and assigns (or reassigns) an adjuster to the claim.
2. Review period: The adjuster reviews the demand letter, supporting documentation, and their own investigation file. This can take two to six weeks.
3. Counteroffer: The insurance company responds with a counteroffer, which is almost always lower than the demand. This is expected and is the starting point for negotiation.
4. Negotiation: Your attorney and the adjuster exchange offers and counteroffers. This back-and-forth typically involves several rounds and can last weeks or months.
5. Resolution or litigation: If both sides reach an agreement, the case settles. If not, your attorney may recommend filing a lawsuit.

How Long Does It Take to Get a Response?

Most insurance companies respond to a demand letter within 30 to 45 days, though there is no universal legal requirement for a specific timeframe. Some states have prompt-response statutes that require insurers to acknowledge claims within a set number of days.

If the insurance company does not respond within a reasonable time, your attorney may follow up in writing, file a bad faith complaint with the state insurance commissioner, or proceed directly to filing a lawsuit. An unreasonable delay in responding to a demand letter can sometimes support a bad faith claim against the insurer.

Can the Demand Letter Amount Change?

Yes. The initial demand amount is a negotiating position, not a final number. However, the demand can also increase if new information surfaces after the letter is sent, such as:

• A medical condition worsens or requires additional surgery
• Previously unknown injuries are discovered
• Additional evidence of the defendant's negligence or misconduct is found
• The defendant's conduct is found to warrant punitive damages

Conversely, if evidence emerges that weakens your case (such as comparative fault issues), the realistic settlement range may decrease.

Demand Letter vs. Filing a Lawsuit

A demand letter is not a lawsuit. It is a pre-litigation tool designed to resolve your claim without going to court. Most personal injury cases (roughly 95 to 97 percent) settle without a trial, and the demand letter is where that process begins.

If the demand letter does not produce a satisfactory offer, your attorney will file a formal complaint in court. Filing a lawsuit opens up additional tools (discovery, depositions) that often strengthen your negotiating position. Many cases settle after a lawsuit is filed but before trial.

What Makes a Strong Demand Letter?

The most effective demand letters share several characteristics:

• Thorough documentation: Every claim is supported by evidence. Medical records, bills, photographs, expert opinions, and wage statements are attached or referenced.
• Clear liability argument: The letter establishes exactly why the defendant is at fault, citing specific evidence and applicable law.
• Compelling narrative: Beyond the numbers, the letter tells your story: how the injury happened, how it changed your life, and what you have endured.
• Realistic demand amount: The number is high enough to leave room for negotiation but grounded enough to be taken seriously by the adjuster.
• Professional tone: Effective demand letters are factual and persuasive, not emotional or threatening. Adjusters respond to evidence, not anger.
