Seven signals that show up in the file before the suit papers do.
Many bodily injury files show signals of a coming lawsuit before the summons arrives. This post sets out seven of them, what the adjuster can do at each one, and where litigation risk prediction tools fall short.
Claims litigation management starts before the lawsuit
Claims litigation management usually begins when the summons arrives. Yet many files show signs of suit well before that point. This post covers those early signals in a bodily injury (BI) claim. It also covers what the adjuster can do at each one, and where litigation risk scores help or mislead.
The stakes are clear in the data. The Insurance Research Council (IRC) studied more than 7.4 million auto injury claims closed with payment between mid-2017 and mid-2022. Across all coverages, attorney representation rose from 40% to nearly 50%, and litigation rates rose from 10% to 18%. In the same IRC release, represented BI claimants waited a median of nearly 440 days for closure. That is more than double the wait for unrepresented claimants.
The cost shows up across liability lines. In 2025, the Casualty Actuarial Society and the Insurance Information Institute (Triple-I) published a joint analysis. It estimated that legal system abuse drove $231.6 billion to $281.2 billion in added liability insurance losses over the past decade. "Legal system abuse" is the authors' term, and estimates of this kind rest on modelling choices.
In insurance litigation avoidance, claim teams need to read the signals early. Not every suit can be avoided, and some should not be. The goal is a file where a suit, if it comes, is a choice rather than a surprise.
Attorney involvement in claims is rising, and it arrives early
A letter of representation is the notice that a claimant has hired a lawyer. It is lawful and common. It does not mean the claim is inflated. It does change the path the claim is likely to take.
Timing has shifted. The IRC surveyed more than 2,000 U.S. adults in July 2026. In that survey, nearly half of claimants who hired an attorney did so within days of the accident. About eight in 10 who consulted or hired one reported being referred to a medical provider. Injury severity and concern about fair compensation were the main reasons respondents gave for hiring a lawyer.
Carrier conduct still matters, though less than many assume. In an IRC poll published in 2016, only 15% of auto injury claimants who talked to an attorney cited delay in settling. The same poll found that 10% were unhappy with the amount offered. That data is a decade old, so treat it as context. Delay is a minority driver, but it is a driver the carrier controls directly.
Seven early signals a file is heading to court
No single signal predicts a lawsuit. When several appear inside a short period, the file deserves closer handling. Rules and practice differ by state, so check your own jurisdiction and guidelines.
1. The timing of the letter of representation
An early letter, before the first recorded statement or within days of the loss, suggests counsel was retained before contact with the carrier. Compare three dates: the loss, the first treatment visit and the letter. A short gap between all three is a pattern worth noting, not a conclusion.
2. Contact breaks down
Calls to the claimant or counsel go unanswered. Requests for records or authorizations sit for weeks. Counsel stops responding to anything except settlement figures. Many practitioners read a drop in two-way contact as a sign that a filing may be near. Treat it as a prompt to act, not as proof.
3. The treatment pattern shifts
Watch for care that changes shape after representation. Examples include a move from primary care to pain management, a jump to injections, or a new surgical consult. Note who made the referral and whether care sits under a letter of protection, an agreement that defers payment until settlement. A related guide covers letters of protection, treatment stacking and billed versus paid.
4. A gap between the demand and the evaluation
A demand far above the carrier's evaluation is normal at first. The signal is a gap that does not narrow after an exchange of documents. Ask what drives the difference: future care, wage loss, a disputed injury or a different reading of liability. If the demand carries a deadline, see the 30-day playbook for time-limited demands.
5. A coverage or liability dispute
A reservation of rights, a coverage question or a contested liability position raises the chance of suit. So does a dispute among several defendants or carriers about who pays. These files need a clear written position, with reasons, sent early.
6. Delay in the carrier's own handling
This signal sits inside the carrier's own process. Look for a late acknowledgment, a file reassigned twice, or weeks with no diary activity. The NAIC model regulation on claim settlement practices says an insurer should acknowledge a notice of claim within 15 days. The same model says file documentation should allow the insurer's activities to be reconstructed. States adopt their own versions, so day counts differ.
7. Venue facts in the file
The file already records where the loss happened, where the claimant lives and where each defendant is based. Those facts point to the courts where suit could be filed. Note them early, and weigh them with your venue guidelines and counsel's view. Treat venue as one input among the others, not a verdict on the file.
The signals at a glance
- Early representation. What it looks like in the file: Letter arrives within days of loss or before first contact. What the adjuster can do: Line up loss, first visit and letter dates; acknowledge counsel promptly.
- Contact breakdown. What it looks like in the file: Unanswered calls, stalled authorizations. What the adjuster can do: Put requests in writing with dates; escalate per guidelines.
- Treatment shift. What it looks like in the file: New specialists, injections, surgical consult, letter of protection. What the adjuster can do: Request referral source and full records; update the medical summary.
- Demand vs evaluation gap. What it looks like in the file: Gap does not narrow after exchange. What the adjuster can do: Write down what drives the gap; request support for each driver.
- Coverage or liability dispute. What it looks like in the file: Reservation of rights, contested fault, several carriers. What the adjuster can do: Send a reasoned written position; involve coverage counsel.
- Carrier delay. What it looks like in the file: Late acknowledgment, reassignment, idle diary. What the adjuster can do: Review idle files; restore contact; document every step.
- Venue facts. What it looks like in the file: Loss location, claimant residence, defendant locations. What the adjuster can do: Note the likely courts; weigh them with the other signals; review the reserve.
The table is a checklist, not a scoring model. As a suggested rule of thumb, two or three signals together justify a supervisor review. Once suit is filed, the handover to defense counsel becomes its own task.
An illustrative file timeline
The timeline below is invented for illustration. It shows how signals can stack in a single auto BI file.
- Day 0: rear-end collision; the claimant reports neck pain at the scene.
- Day 3: a letter of representation arrives before any recorded statement.
- Day 9: the adjuster requests medical authorizations in writing. No reply follows.
- Day 20: records show a move from physical therapy to cervical injections under a letter of protection.
- Days 21 to 56: the file is reassigned, and the diary shows no activity for five weeks.
- Day 60: a demand arrives far above the evaluation, with a 30-day deadline.
By day 20, three signals had appeared: early representation, broken contact and a treatment shift. A supervisor review at that point could have restored contact and asked for the referral source. The five idle weeks that followed were the carrier's own signal.
Where litigation risk prediction tools fall short
Some carriers now run litigation risk prediction, in which a model scores open claims for the chance of suit. These scores can help sort a large desk. They also have limits that claims leaders should understand before acting on one.
Scores built on structured fields can miss the file
Some models rely mainly on structured fields such as loss type, injury codes, claimant age, venue, attorney flag and reserve. Much of the signal above lives elsewhere: in adjuster notes, medical records, provider letters and correspondence. A model that cannot read those documents may only register a treatment shift after the bills post. An adjuster reading the records might catch the surgical consult weeks earlier.
Training data lags the claims environment
A model trained on closed claims learns from the past. Closed BI claims with counsel can take more than a year to resolve, as the IRC median shows. So a change in local practice, a new referral network or a statute change may not show up for some time. The NAIC model bulletin on insurers' use of AI names this risk as model drift. It lists records of validation, testing and drift monitoring among the documents a regulator may request.
Explainability is a regulatory expectation
The same bulletin, adopted by the NAIC in December 2023, covers decisions made or supported by AI systems. Its control factors include the extent of human involvement in the final decision and the transparency and explainability of outcomes. States adopt it one by one, so check the NAIC adoption map for yours. A bare score with no reasons attached may be hard to defend in a market conduct review. It is also hard for an adjuster to act on.
A score is not a plan
A high score says a file may go to suit. It does not say why, or what to do next. The adjuster still has to find the driver and choose the step. That might be a records request, a call to counsel, a reserve change or a revised offer. Routing a file to a queue with no plan attached adds a step and saves none.
Records also matter once suit is filed. In federal court, discovery reaches any nonprivileged matter relevant to a claim or defense and proportional to the needs of the case. Scores and their inputs in the claim file could fall within that scope. Ask counsel how your organization should record model outputs.
False confidence cuts both ways
A low score can lull a desk into leaving a file alone while contact quietly breaks down. A high score can push a file into an adversarial posture it did not need. Either error costs money. Treat the score as one more input, and record why the adjuster agreed or disagreed with it.
What good claims litigation management looks like
Good practice gives tools and adjusters distinct roles. The tool reads and organizes the file at a scale that is hard to reach by hand. The adjuster weighs the evidence, talks to people and makes the call.
In practice, that comes down to five steps:
- Read the documents, not just the fields. Pull signals from notes, records and letters, with a link to the page each came from.
- Show reasons with every flag. Each flag should cite its evidence, so an adjuster can check it quickly. A related guide explains how to check a claims AI answer against the source page.
- Pair each signal with an action. Use the table above as a starting point, and adapt it to your guidelines.
- Watch the carrier's own clock. Review idle files and late acknowledgments every week, since that delay sits within the carrier's control.
- Retest the model. Compare predicted and actual suit rates on recent closures, and document the results.
Platforms built for bodily injury claim file review, such as amaise, process unstructured claim documents and flag key details for the adjuster. The adjuster still reads the source and decides what to do.
Strong claims litigation management is not a prediction contest. It is the daily work of reading the file, spotting the signals early and acting on them with a written record. Tools make that work faster. Judgment still decides whether a file settles, goes to suit or is defended.
Common questions
What is the earliest sign a BI claim may end in a lawsuit?
Often it is a letter of representation that arrives within days of the loss, alongside a treatment shift or a break in contact. One signal alone proves little. As a rule of thumb, two or three together justify a supervisor review.
Can a litigation risk score replace adjuster judgment?
No. A score can help sort a desk, but it does not explain the driver or choose the next step. The adjuster reads the evidence, decides the action and records the reasons.
What can the carrier control in litigation avoidance?
Its own handling. Acknowledge promptly, keep contact open, put requests in writing, explain coverage and liability positions with reasons, and review idle files. These steps do not prevent every suit, but they support a defensible file.
Key takeaways
- Claims litigation management works best before suit, because many files show signals before the summons arrives.
- Seven signals matter: early representation, contact breakdown, treatment shifts, a demand gap that will not narrow, coverage or liability disputes, carrier delay and venue facts.
- Delay in the carrier's own handling is a signal the carrier controls directly.
- Some litigation risk scores rely on structured fields and can miss what sits in notes and medical records. Models can also drift as data ages.
- A score is not a plan: pair every flag with its evidence and an action, and let the adjuster make the call.
