You have the medical records. You have the police report. You have the bills. And your demand letter is still sitting in drafts because you know a generic letter won't move the adjuster — and a bad one can actually hurt the case. Here's what you need to know before you send it.
What the adjuster is actually doing when they read your letter
Most PI attorneys picture an adjuster sitting down with a coffee, reading their demand letter carefully, and making a thoughtful valuation. That's not what happens.
The adjuster is entering data into software. Specifically, most major insurers — State Farm, Allstate, USAA, Farmers — use Colossus or a similar program called Claim Outcome Advisor. The software assigns severity points to your client's injuries and spits out a settlement range before the adjuster forms a single independent opinion.
Here's the part most attorneys miss: Colossus only scores what the adjuster enters. And the adjuster only enters what appears in both the medical records AND your demand letter. If a "triggering factor" — a specific injury descriptor, a documented limitation, a confirmed diagnosis — doesn't appear in your letter using the right language, the adjuster doesn't enter it. The software doesn't score it. Your client gets less.
Colossus can be intentionally set to underpay claims by 12–20%. Adjusters have limited authority to deviate from its range without a management override. Your demand letter is what gives them — or denies them — the ammunition to push for a higher number.
This is the game. Understanding it changes how you write every letter.
When to send the demand letter — and why most attorneys send too early
The most common mistake. An attorney sends the demand letter before the client reaches Maximum Medical Improvement (MMI) because they want to move the case. The adjuster notes it, enters whatever medical is available, and the software generates a range based on incomplete data. You've anchored low. Getting back to fair value from there is harder than it looks.
Wait for MMI — or at minimum, wait until the treating physician has documented a clear prognosis. Future medical costs (surgery, ongoing PT, permanent impairment) are often the biggest component of a high-value demand. If they're not in the letter because treatment isn't complete, you've left real money on the table.
- Send after MMI whenever the case timeline allows
- If the statute of limitations is approaching, send with a clear notation that treatment is ongoing and damages are subject to supplementation
- For high-value cases, consider a two-part demand — liability first, damages once treatment concludes
The four elements that actually move adjusters
Every demand letter guide tells you to include "facts of the accident, medical records, lost wages, and pain and suffering." That's the minimum. It's table stakes. It won't move a Colossus-driven adjuster a dollar past the software's floor.
What moves them is this:
Liability specificity. Don't say "defendant was negligent." Say which statute they violated. Texas Transportation Code §545.062 (following too closely). 49 C.F.R. §395.3 (FMCSA hours of service). California Vehicle Code §21703. Cite the code. The adjuster enters it. Colossus treats statutory violations as aggravating liability factors — it shifts the range upward.
Injury language that mirrors the medical chart. Colossus reads the adjuster's data entries, not your narrative. The adjuster's entries are supposed to mirror the physician's chart. Your demand letter should mirror both. Use the exact diagnostic language from the records — "L4-L5 disc herniation with radiculopathy" not "back injury." "Cervical spine sprain/strain with documented muscle spasm" not "neck pain." The specific ICD-10 codes your treating physician used are your roadmap.
Documented limitations. Functional limitations — can't lift over 10 pounds, can't sit for more than 20 minutes, can't return to prior occupation — are separate scoring inputs in Colossus. List them explicitly with supporting documentation. A physician's note saying "patient reports difficulty with overhead activities" is worth less than one saying "patient is restricted from lifting over 10 lbs for 6 weeks." Get the specifics from your treating provider before you write the letter.
Trial readiness signal. Colossus actually tracks your litigation history. Adjusters know which plaintiff attorneys take cases to trial and which ones always settle. If you're known for settling, the software (and the adjuster) knows your range. Referencing your trial preparation in the letter — not as a threat, but as a factual statement — signals you mean business. "We are prepared to proceed to litigation if a fair resolution cannot be reached" is different from silence on the subject.
Structuring a high-value demand letter — the actual order
Lead with liability. Not with sympathy, not with a chronology of medical appointments. The adjuster needs to know immediately that liability is clear and that fighting it will be expensive. Then tell your client's story. Then go into medical.
Here's the structure that works:
- Opening paragraph: State the purpose, identify the parties, give the accident date and location, and lead with your strongest liability fact. One sentence on why this case is the defendant's fault — specific, statute-cited, documented.
- Liability section: Facts of the accident in chronological order. Police report findings. Witness statements. Any regulatory violations. Traffic citations issued. Accident reconstruction if applicable.
- Medical section: Treating providers listed chronologically. Each injury documented using exact clinical language from the chart. Treatment dates, procedure codes, diagnoses. Current status and prognosis. Future medical needs with cost estimates from treating or evaluating physician.
- Damages section: Itemized. Medical to date (itemized by provider). Lost wages (documented with employer letter and pay stubs). Future medical costs. Future lost earning capacity if applicable. Pain and suffering — described specifically, not generically.
- Demand: A specific dollar figure. Not a range. Adjusters interpret ranges as uncertainty. A specific number signals you've done the math and you stand behind it.
Case size should influence letter length. A $15,000 soft tissue claim doesn't need 12 pages. A commercial truck accident with a herniated disc and a six-figure surgery estimate does. A letter that's disproportionately long for a small case signals inexperience. A letter that's thin on a big case signals you're not serious.
What kills a demand letter before the adjuster finishes page one
Experienced PI attorneys know these instinctively. Less experienced ones learn them the hard way.
Sending before treatment is complete. Already covered. Don't do it unless the SOL forces your hand.
Vague liability. "The defendant failed to exercise reasonable care" is not a liability argument. It's a placeholder. Adjusters roll their eyes. Defense counsel uses it to justify a low offer.
Missing the soft tissue documentation. Soft tissue injuries are already treated skeptically by Colossus. If your letter doesn't have documented muscle spasm, restricted range of motion, or physician-confirmed limitations — with the specific language — the software scores it at the floor. Your treating physician's records have to explicitly note these findings. If they don't, get a supplemental narrative from the doctor before you send.
Emotional appeals without evidence. Describing your client's suffering matters — but adjuster-facing letters need evidence behind every claim. "My client can no longer play with her children" means nothing without a physician's documented functional restriction. Lead with the documentation. Follow with the human story.
Weak demand amounts. Demanding $15,000 on a case with $40,000 in medical tells the adjuster you don't know the value of your own case — or that you're desperate to settle fast. Research comparable verdicts in your jurisdiction. Know your multiplier. Know your per diem calculation. Demand the right number.
A real example — what this looks like in practice
Client: James Okafor, 41, warehouse supervisor, Houston TX. Rear-ended at a complete stop on I-10 by a commercial delivery truck on August 7, 2023. Impact speed estimated at 47 mph per accident reconstruction report. Driver had logged 11.4 hours of on-duty time at impact — a direct violation of 49 C.F.R. §395.3.
Injuries: L4-L5 disc herniation confirmed on MRI. C5-C6 disc bulge. Cervical radiculopathy with documented upper extremity weakness. ER, orthopedist, 14 weeks of PT, two epidural steroid injections. Total medical to date: $34,560. Treating surgeon recommends L4-L5 discectomy: estimated $45,000–$65,000. Lost wages: 11 weeks at $28/hr = $12,320.
The demand letter opens with the FMCSA violation. Not with the accident narrative. Not with a summary of medical expenses. With the single most damaging liability fact: the driver had been on duty for 11.4 hours when federal law requires a break at 11. That one fact, cited to the specific federal regulation, triggers an aggravated liability flag in Colossus. It also tells the adjuster — and their defense counsel — that going to trial on this case means a jury hearing about a fatigued commercial driver who violated federal law.
The medical section uses exact ICD-10 language from the treating physician's chart. The documented limitations — no lifting over 15 lbs, no prolonged sitting, unable to return to warehouse duties — are listed explicitly, matched to physician notes.
Demand: $285,000. Specific. Documented. Supported. That's how it's done.
Drafting a letter like this used to take three to four hours. Tools like Jurovy can get you a verified first draft in 60 seconds — citations checked against 7 million court opinions before you see them. You still review it, edit it, make it yours. But the blank page problem and the three-hour slog? Those are gone.
The one thing that separates good demand letters from great ones
Great demand letters make the adjuster's job easier, not harder.
That sounds counterintuitive. But the adjuster is trying to justify a number to their supervisor. The defense attorney is trying to assess trial risk. Your letter is their primary input. Give them everything they need to say yes. Clear liability. Specific medical. Documented limitations. Reasonable but firm demand. A quiet signal that you'll go to trial if you have to.
A letter that's hard to read, vague on liability, or thin on medical doesn't get rejected — it gets ignored. It sits in a stack. The adjuster moves on to the next file. Your client waits.
Write the letter the adjuster can act on. That's the one that settles.
