A personal injury demand letter is your formal request for compensation from the party responsible for your injuries. Whether you were hurt in a car accident, slip and fall, or any other incident, a well-crafted demand letter is the cornerstone of successful settlement negotiations.

This guide covers everything you need to know about writing a demand letter for any type of personal injury case, including what to include in your settlement demand package and how to negotiate effectively.

Why Demand Letters Matter

Over 95% of personal injury cases settle without going to trial. Your demand letter often determines whether you receive a fair offer or a lowball settlement. It's your first — and sometimes only — chance to make your case to the insurance company.

What Is a Personal Injury Demand Letter?

A personal injury demand letter is a formal document sent to the at-fault party (or their insurance company) that:

  • Describes the incident that caused your injuries
  • Explains why the other party is legally responsible (liability)
  • Details your injuries and medical treatment
  • Documents all your damages (medical bills, lost wages, pain and suffering)
  • States the specific dollar amount you're demanding as compensation

Think of your demand letter as a persuasive legal brief. You're presenting your case in the strongest possible terms to convince the insurance company to pay fair compensation.

A Demand Letter Does

  • ✓ Formally initiate negotiations
  • ✓ Create a written record of your claim
  • ✓ Force the insurer to take you seriously
  • ✓ Set an "anchor" for negotiations
  • ✓ Demonstrate you're prepared to pursue your case

A Demand Letter Doesn't

  • ✗ Guarantee a settlement
  • ✗ Force the insurer to accept your demand
  • ✗ File a lawsuit (that's a separate step)
  • ✗ Stop the statute of limitations clock
  • ✗ Admit any fault on your part

Types of Personal Injury Cases

Demand letters apply to virtually any situation where you've been injured due to someone else's negligence. The core structure remains the same, though specific details vary by case type.

Motor Vehicle Accidents

Car, truck, motorcycle, Uber/Lyft, pedestrian, and bicycle accidents. Usually sent to the at-fault driver's auto insurance company.

Slip and Fall / Premises Liability

Injuries on someone else's property due to hazardous conditions. Sent to the property owner or their liability insurance. Must prove they knew (or should have known) about the dangerous condition.

Dog Bites

Animal attack injuries. Many states have strict liability for dog bites. Claim typically goes against the owner's homeowner's or renter's insurance.

Medical Malpractice

Healthcare provider negligence. These cases are complex and almost always require an attorney and expert witnesses.

Product Liability

Defective products causing injury. Claims may go against manufacturers, distributors, or retailers.

Assault & Battery

Intentional harm caused by another person. Criminal charges are separate from civil claims for compensation.

Key Components of a Demand Letter

Regardless of your case type, every effective demand letter includes these essential components:

1

Identifying Information

Your name, address, contact information, and claim/policy number (if applicable). Identify the at-fault party and their insurance company.
2

Statement of Facts

A clear, chronological narrative of what happened. Include date, time, location, and exactly how the incident occurred. Stick to facts — avoid editorializing.
3

Liability Analysis

Explain why the other party is legally responsible. Reference specific laws, regulations, or duties they violated. Include evidence like police reports, incident reports, witness statements, or photos.
4

Injury Description

Detail every injury, from major to minor. Use medical terminology from your doctor's records. Describe all treatment: emergency care, hospitalizations, surgeries, physical therapy, medications, and any ongoing or future care needed.
5

Impact Statement

Explain how injuries have affected your life. Cover pain and suffering, emotional distress, sleep problems, relationship strain, inability to work, and lost quality of life. Be specific and personal.
6

Itemized Damages

List every economic loss with specific dollar amounts:
  • Medical expenses (past and future)
  • Lost wages and loss of earning capacity
  • Property damage
  • Out-of-pocket expenses
  • Non-economic damages (pain and suffering)
7

Demand Amount

State the total compensation you're seeking. This should be your "opening ask" — higher than your minimum acceptable amount to leave room for negotiation.
8

Response Deadline

Give a reasonable deadline for response (usually 30 days). Indicate your willingness to negotiate but also your readiness to pursue legal action if necessary.

Pro Tip: The Power of Specificity

Vague claims get ignored. Instead of "I suffered greatly," write "I was unable to sleep more than 3 hours at a time for the first 6 weeks due to back pain, and I still require a heating pad every night." Specifics are persuasive.

Your Settlement Demand Package

Your demand letter doesn't stand alone — it's part of a complete settlement demand package. Think of the package as your "evidence file" that proves every claim in your letter.

Documents to Include

Medical Documentation
  • • Medical records from all providers
  • • Itemized medical bills
  • • Pharmacy records/prescriptions
  • • Physical therapy notes
  • • Future treatment estimates
Incident Documentation
  • • Police report or incident report
  • • Photos of scene, injuries, damage
  • • Witness statements
  • • Video footage (if available)
  • • Weather/condition reports
Lost Income Documentation
  • • Employer letter confirming missed work
  • • Pay stubs showing lost wages
  • • Tax returns (if self-employed)
  • • Letter on reduced earning capacity
Pain & Suffering Evidence
  • • Pain journal entries
  • • Before/after photos
  • • Statements from family/friends
  • • Mental health records (if applicable)

Organize Your Package

Number your pages and create an index. Insurance adjusters review dozens of claims. A well-organized package makes it easy for them to find supporting evidence for each claim, which increases your credibility and likelihood of a fair offer.

Negotiation Tips After Sending Your Letter

Sending your demand letter starts the negotiation process. Here's how to navigate it effectively:

1. Expect a Low Initial Offer

The insurance company's first counteroffer is almost always much lower than what they're willing to pay. This is standard negotiating tactics. Don't be insulted or discouraged.

2. Respond in Writing

Always respond to offers in writing. Acknowledge their offer, explain specifically why it's inadequate (referencing your evidence), and make a counter-offer. Keep a paper trail.

3. Move Slowly Toward the Middle

Don't drop your demand by 50% in one step. Make incremental moves. If you demanded $100,000 and they offered $20,000, counter at $85,000 or $90,000 — not $60,000.

4. Know Your Bottom Line

Before negotiating, determine your minimum acceptable settlement. Factor in attorney fees (if applicable), medical liens, and what you'd realistically get at trial.

5. Be Patient but Persistent

Negotiations often go back and forth 3-5 times over weeks or months. Don't accept a lowball offer out of frustration. Stay professional and persistent.

When to Hire a Personal Injury Attorney

You don't legally need an attorney to send a demand letter or negotiate a settlement. However, there are situations where legal representation is strongly recommended:

Severe or Permanent Injuries

If you have significant injuries, surgery, ongoing disability, or life-altering consequences, the stakes are too high to go it alone.

Disputed Liability

If the insurance company claims you were at fault or there's a legitimate question about who caused the accident.

Multiple Parties Involved

Multi-vehicle accidents, shared fault situations, or claims against businesses require more complex legal strategies.

Insurance Company Acting in Bad Faith

If the insurer is refusing to respond, making unreasonably low offers, or using delay tactics.

High-Value Claims

Claims exceeding $50,000-$100,000 benefit significantly from professional representation. Studies show represented claimants receive higher settlements.

Contingency Fee Arrangements

Most personal injury attorneys work on contingency: they take 33-40% of your settlement but only if you win. There's no upfront cost, and studies show claimants with attorneys typically net more money even after fees.

Frequently Asked Questions

How long should my demand letter be?

Most effective demand letters are 3-6 pages, plus attachments. Focus on being thorough but concise. Every sentence should add value to your case.

How do I calculate my demand amount?

Total your economic damages (medical bills, lost wages), then add non-economic damages (typically 1.5-5x your economic damages for pain and suffering). Your demand should be higher than your minimum acceptable amount to leave negotiation room.

What if the insurance company ignores my letter?

Follow up in writing after your deadline passes. If they continue to ignore you, consult an attorney about filing a lawsuit. Sometimes the threat of litigation gets their attention.

Can I negotiate without a lawyer?

Yes. For minor injuries with clear liability, many people successfully negotiate their own settlements. However, for serious injuries or disputed liability, an attorney typically adds significant value.

How long does settlement negotiation take?

Typically 1-6 months after sending your demand letter. Complex cases can take longer. Be patient — rushing often means accepting less than your case is worth.

Should I accept the first offer?

Almost never. The first offer is usually a starting point for negotiations, often 30-50% below what the insurer is willing to pay. Always counter-offer.
