How to Write a Demand Letter for Personal Injury in Texas

After an injury caused by someone else, the demand letter is usually the document that moves your claim from paperwork to a settlement conversation. It’s the letter you or your attorney send to the at-fault party’s insurer laying out what happened, why they’re responsible, and the compensation you’re asking for. Writing one for a personal injury claim in Texas is less about legal formatting and more about building a documented, specific case the insurer has to take seriously.

This guide walks through how to write that letter step by step, what to include, and how Texas rules on deadlines and documentation shape when and how you send it. The mechanics apply to most demand letters, but the timing and legal context below are specific to Texas personal injury claims.

Key Takeaways

• A demand letter is a settlement tool, not a court filing. In most Texas personal injury cases, it isn’t legally required before you sue, but it’s a standard step that often resolves the claim without litigation.
• Timing matters. Most claimants send the letter after reaching maximum medical improvement, when the full cost of the injury is documented.
• Texas gives most personal injury claimants two years from the injury to file suit, which sets an outer limit on how long you can wait to send a demand and negotiate.
• The letter’s strength comes from documentation, a clear liability explanation, itemized medical records and bills, and a specific compensation figure, not from aggressive language.

How to Write a Personal Injury Demand Letter, Step by Step

A strong demand letter follows a predictable sequence. Each step builds the record that supports the number you ultimately ask for, which is why skipping ahead to the demand before the documentation is ready tends to weaken the letter.

1. Establish liability: State plainly what happened and why the other party is at fault, tied to the facts: the date, location, and sequence of the incident. A demand letter that asserts fault without explaining how the other party caused the injury gives the insurer an easy reason to push back.
2. Gather and organize your evidence: Collect the accident or incident report, photographs, witness statements, your medical records and itemized bills, and documentation of lost wages. These become the exhibits that back up both liability and the dollar figure you’re claiming. Evidence also gets harder to collect as time passes, so start early even if you won’t send the letter for months.
3. Wait for the right moment to calculate damages: In most Texas personal injury cases, you send the demand after you’ve finished treatment or reached maximum medical improvement, the point where your condition has stabilized, and the full cost of the injury is known. Sending before then risks understating damages you haven’t incurred yet. This timing has an outer limit, though: Texas generally gives you two years from the date of injury to file a personal injury lawsuit, so the demand-and-negotiation process has to leave room to file before that deadline runs. If you’re weighing when to send in relation to the broader personal injury claim timeline, that filing deadline is the fixed point everything else works backward from.
4. Itemize your damages: Separate economic damages (medical bills, future medical needs, lost wages) from non-economic damages (pain and suffering, physical impairment). Listing each category with the supporting documentation shows the insurer how you arrived at your number rather than asking them to trust a lump sum. For example, an itemized breakdown might total current medical bills, estimated future treatment, documented lost income, and a separate figure for pain and suffering; the specific amounts depend entirely on your injuries and losses.
5. State a specific demand: Name the compensation figure you’re seeking. A precise number, supported by the itemization above, signals that the demand is calculated rather than arbitrary.
6. Set a response deadline: Give a specific calendar date by which you expect a response, and state what you’ll do if the deadline passes without one. For an ordinary Texas car-accident or personal injury claim, no pre-suit demand letter is legally required before filing suit, so the letter functions as a strategic settlement tool rather than a procedural box to check. That means the deadline is yours to set based on what’s reasonable, not a statutory requirement.
7. Send it via certified mail: Send the letter certified with return receipt requested. This documents that the insurer received it and when, which starts the response clock and creates a record if the claim later moves toward litigation.

With the letter sent, the next questions most people have are how long the insurer has to respond and what Texas rules affect the claim, both covered below.

How Long Should You Give the Insurer to Respond?

There’s no law setting a required response window for a personal injury demand letter in Texas, so the deadline is a practical judgment call. A 30-day window is common for insurers reviewing a personal injury demand, since they need time to evaluate the medical records and liability evidence. Simpler claims with less documentation may warrant a shorter window.

Whatever window you choose, state a specific calendar date rather than a vague “within 30 days,” and note that certified-mail delivery starts the clock. Setting a firm date keeps the claim moving and gives you a clear point at which to decide your next step if the insurer doesn’t respond.

What Is a Demand Letter, and Is It Required in Texas?

A demand letter is not legally required before filing a personal injury lawsuit in Texas, but it’s a standard strategic step that often resolves a claim without going to court. It’s a formal letter from the injured party (or their attorney) to the at-fault party or their insurer that describes the dispute, explains liability, and states the compensation being sought.

The elements that give a demand letter its weight are consistent: a clear identification of the parties, a factual description of the incident, an itemized account of the damages, a specific demand, and a response deadline. Demand letters are used in other contexts too, such as contract and debt disputes, but the structure and stakes in a personal injury claim are what this guide addresses.

Texas Legal Considerations That Affect Your Demand

A few Texas-specific rules shape what your demand letter needs to do and what you can realistically recover.

• Pre-suit notice requirements: For an ordinary auto accident or negligence-based personal injury claim, Texas does not require you to send a demand letter or pre-suit notice before filing. Certain other claims do carry statutory notice requirements: a claim under the Texas Deceptive Trade Practices Act requires 60 days’ pre-suit written notice, and a medical malpractice claim requires pre-suit notice under Chapter 74 of the Civil Practice and Remedies Code. If your situation involves one of those, the notice rules change what the letter has to accomplish, which is a good reason to have an attorney confirm what applies.
• The two-year filing deadline: Most Texas personal injury claims must be filed within two years of the injury under Civil Practice and Remedies Code Section 16.003. This deadline is why the demand-and-negotiation window can’t stretch indefinitely, even when you’re waiting on treatment to finish.
• Policy limits and liens: The at-fault party’s available insurance policy limits cap what the insurer will realistically pay, which affects what a reasonable demand looks like. Separately, if your own health insurer or a hospital paid for your treatment, they may have a right to be repaid out of your settlement. Texas subrogation rules determine how much of your recovery goes to those repayments, which is worth understanding before you settle on a demand figure.

Can You Write the Demand Letter Yourself?

Yes, you can write a demand letter yourself, and for a straightforward claim with clear liability and modest injuries, many people do. Where self-drafting tends to fall short is in the parts that are hard to get right without experience: putting an accurate value on non-economic damages like pain and suffering, building a liability narrative that anticipates the insurer’s defenses, and handling policy-limit and lien or subrogation issues that determine how much of a settlement you actually keep.

Those are the situations where having an attorney draft or review the letter tends to matter most, because a demand that understates your damages or ignores a lien can cost more than it saves. If you’re unsure whether your claim is one you should handle yourself, our guide on when to hire a personal injury lawyer in Texas walks through the factors.

Putting Your Texas Demand Letter Together 

Writing a demand letter for a personal injury claim in Texas comes down to documentation and timing: a clear explanation of fault, itemized proof of what the injury cost you, and a specific demand sent once your damages are fully known and within the two-year filing window. A letter built that way gives the insurer a reason to negotiate seriously.

Frequently Asked Questions About How to Write a Personal Injury Demand Letter 

Do you have to send a demand letter before suing in Texas?

For most personal injury and auto accident claims, no. Some claims, such as DTPA and medical malpractice claims, do require pre-suit notice, so it’s worth confirming what applies to your situation.

When should I send a demand letter if I’m still in treatment?

It’s usually best to wait until you’ve finished treatment or reached maximum medical improvement, so your demand reflects the full cost of the injury. Just make sure the timing still leaves room to file within the two-year deadline if the claim doesn’t settle.

What’s a reasonable response deadline for a demand letter?

A 30-day window is common for personal injury claims, since insurers need time to review medical records and liability evidence. State a specific calendar date and note that certified-mail delivery starts the clock.

How do policy limits affect my demand?

The at-fault party’s insurance policy limits cap what the insurer will realistically pay, so a demand well above those limits may not be recoverable from that policy. Knowing the available coverage helps set a demand that’s both ambitious and realistic.

How do health insurance or hospital liens affect what I recover?

If your health insurer or a hospital paid for your treatment, they may be entitled to repayment out of your settlement under Texas subrogation rules. That repayment comes out of your recovery, so it affects your net result and is worth accounting for before you settle on a number.
