A demand package is the plaintiff's case for a number, often 100 to 500+ pages with a 30-day deadline. Here's what's inside one, why it's built to be read quickly, and how adjusters respond.
A demand package is the plaintiff attorney's formal case for a settlement number: a bound or digital bundle of medical records, bills, correspondence, and argument, typically 100 to 500 pages and sometimes far more, built to make a large settlement look reasonable and a refusal look risky. Packages typically arrive with a deadline, often 30 days, after which the plaintiff says the offer expires and the case proceeds to litigation. Understanding how a demand package is built, and what it is designed to make an adjuster miss, is the first step to answering one well.
What Is a Demand Package?
On a serious bodily injury claim, the demand package is assembled to be read in the plaintiff's order and to lead to the plaintiff's conclusion. The cover letter carries the narrative: a careless defendant, a badly injured plaintiff, and a number that follows from the two. Everything behind the letter exists to support that narrative.
A typical package includes:
- A cover letter and demand narrative stating the claimed facts, injuries, and dollar figure.
- Medical records from every treating provider, mixing handwritten clinical notes, typed discharge summaries, imaging reports, physical therapy logs, and pharmacy histories.
- Itemized bills and diagnostic imaging, often in codes that do not map cleanly onto the clinical narrative.
- A lost-wage calculation supported by employment records.
- Sometimes a day-in-the-life account, photographs, or letters from retained experts.
Why the 30-Day Clock Is a Pressure Tactic
Two features make a demand package hard to answer well.
The first is the deadline itself. The clock compresses the time an adjuster has to read several hundred pages, find the weaknesses, and respond, and it raises the cost of missing something, because a demand mishandled near its deadline can later support a bad-faith argument.
The second is anchoring: the package opens high on purpose, and the size of the opening number pulls the whole negotiation upward unless the defense can answer it with specific facts drawn from the record.
Larger plaintiff firms now use templates, paralegal teams, and their own software to assemble these packages at volume, so carriers face more of them, arriving faster, each built with more care than the file's merits may warrant.
The Psychology Behind the Number
Anchoring
Anchoring is a well-documented negotiation tactic: an opening number, however unsupported, becomes the reference point every later offer gets measured against. It works on adjusters and juries alike, and it works best against a reader who has not yet found the specific fact that contradicts it. An adjuster negotiating without that fact is negotiating from behind, no matter how experienced they are.
The reptile approach
A 2009 book by David Ball and Don Keenan popularized what plaintiff attorneys call the reptile approach: shifting attention away from the narrow legal question of what the standard of care required, toward a broader sense of community danger, so the reader (ultimately a juror, but the adjuster reads the same narrative first) responds from a place of self-protection rather than a careful read of the facts. The tactic starts in depositions, where plaintiff counsel builds a record of broad safety admissions long before a demand is ever sent, then weaves those admissions into the package's narrative.
Six Things to Look for When Responding to a Demand Package
Answering a demand package well means finding the specific items the plaintiff's narrative was built to obscure. Experienced adjusters and defense counsel work through the same checklist on every serious file:
- Treatment gaps: silences in the timeline of care that undercut a claimed severity story, especially in the weeks immediately after the incident.
- Prior injuries or conditions affecting the same body part, often buried in records from years earlier and rarely featured by the plaintiff.
- Billing that does not match the documented care: a volume or type of treatment that outpaces the clinical notes.
- Records that are referenced in the narrative but missing from the package, which is itself a signal worth following up on.
- Internal inconsistencies between what the claimant told a provider, what they told the adjuster, and what employment or surveillance records show.
- Whether the claimed injury actually connects to the reported event and mechanism: the causation question underneath the whole demand.
Each of these is a specific lever the adjuster can use to answer an inflated anchor, and each one has to trace to a page in the record the adjuster can open and confirm. A finding the adjuster cannot verify in seconds is not useful on a file with six figures of exposure, because re-verifying every line by hand erases whatever time was saved finding it.
How to Respond Under Time Pressure
The practical response follows from the checklist above, compressed into the days the clock allows. Read the narrative first to understand what number is being anchored and why. Build a timeline of treatment across every provider in the file, since gaps and inconsistencies only become visible once visit dates are lined up against each other. Cross-reference any prior-claim or prior-condition history the carrier already holds. Total the billed treatment against the diagnosis to check for volume that does not fit. Then draft the response around the specific facts found, not a general rebuttal, because a response that cites the page and the date is the one that actually moves a negotiation.
The volume of a modern file (routinely past 250 pages, and often well beyond that on catastrophic claims) is why this process has become the first place carriers are applying AI-assisted document analysis: not to shorten the file, but to surface these six categories of finding fast enough to matter inside the deadline.
Frequently Asked Questions
What is a demand package in a personal injury claim?
A demand package is the plaintiff attorney's formal case for a settlement amount. It typically includes a cover letter with the claimed narrative, medical records from every treating provider, itemized bills, a lost-wage calculation, and sometimes expert letters or a day-in-the-life account. Packages commonly run 100 to 500 pages and often carry a response deadline, frequently 30 days.
How long do I have to respond to a demand letter?
Demand letters typically state their own deadline, commonly around 30 days, after which the plaintiff may say the offer expires and the case proceeds toward litigation. There is no universal legal deadline; the timeframe is set by the plaintiff's letter and by any applicable claims-handling regulations in the carrier's state.
What is anchoring in insurance settlement negotiations?
Anchoring is a negotiation tactic where the first number offered, however inflated, becomes the reference point the rest of the negotiation is measured against. Plaintiff attorneys use it deliberately in demand packages by opening with a figure well above what the record would historically support, which pulls the eventual settlement upward unless the defense can answer with specific, documented facts.
What is reptile theory in personal injury litigation?
Reptile theory is a plaintiff trial strategy, popularized by a 2009 book by David Ball and Don Keenan, that frames a case around community safety rather than the narrow legal standard of care, aiming to make jurors decide from fear and self-protection. The approach is built during depositions and often carries into the framing of a demand package well before trial.
