Winning the Conversation: Tools That Help Adjusters Stay in Control of APD Arbitration

September 9, 2026 / 6 min read

Summary

Rising claim severity, increasing caseloads, and workforce turnover are putting new pressure on auto property damage (APD) claims teams. Determining liability, assessing comparative fault, and documenting decisions consistently have become more challenging, increasing the risk of missed subrogation opportunities and weaker arbitration outcomes.

Too often, claims default to 100/0 liability decisions when the facts support shared fault. As APD arbitration becomes more complex, carriers need integrated liability workflows that help adjusters evaluate evidence, apply state-specific statutes, and make more defensible liability decisions from FNOL through arbitration.

When liability is identified early, carriers are better positioned to recover later.

APD arbitration depends on more than the final contention. It depends on whether the initial fault determination was supported by the right evidence, accurate comparative-fault analysis, applicable statutes, and clear documentation showing their rationale from the start. Verisk’s Liability Navigator® helps carriers move from fragmented, manual reviews to a guided accident liability workflow that supports stronger decisions from FNOL through carrier-to-carrier negotiation and arbitration.

Most auto property damage disputes aren't decided in arbitration. They're decided weeks earlier by an adjuster making a call with whatever evidence they happened to gather. Too often, that call is 100/0.

When an adjuster is buried in caseload, the path of least resistance is to assign the loss entirely to their own insured. The file closes as a paid claim with no recovery pursued, never reaching subrogation or the carrier-to-carrier negotiation that could lead to arbitration. Winning liability arbitration is a documentation discipline that starts at first notice of loss (FNOL).

Three forces are squeezing the adjuster’s desk

An institutional knowledge gap. The industry faces roughly 400,000 retirements by the end of 2026, with about a quarter of the adjuster workforce retiring within five years. Gen Z isn’t filling the pipeline at replacement rate, and veteran intuition about comparative negligence is walking out the door.
Caseload volume. Arbitration Forums member carriers filed roughly 2.4 million subrogation demands and 1.2 million arbitration disputes last year, with more than $26 billion contested. Industry estimates put manual review at roughly 80 minutes per file.
Rising APD severity. Higher vehicle repair costs, total-loss values, and rental expenses are raising the stakes on every liability decision. The average cost per auto liability claims climbed 67.5 percentage points cumulatively between 2019 and 2025, pushing the gap between settling a physical damage claim and settling a liability claim to a ten-year high.

The cost of bypassing a comparative-fault assessment is materially higher than it used to be.

The three failure modes that decide APD arbitrations

Defaulting to 100/0 when the facts support a split

The costliest mistake is never identifying comparative fault in the first place. When shared liability goes unrecognized early, carriers can miss recovery opportunities before the file ever reaches negotiation or arbitration.

Consider a multi-lane left turn: Your insured crosses three lanes safely and gets struck in the fourth. The other driver had a clear view of the turning vehicle and sufficient time to react. That's a 70/30 or 60/40 call, not a clean 100/0. Adjusters who don't think in percentages don't recover anything.

Summarizing the statement instead of memorializing it

Ask a long-tenured claims professional where carriers lose cases they should have won, and the answer comes fast: "It's documentation—having the facts memorialized."

The failure plays out predictably:

The adjuster takes a recorded statement, types a summary into the file notes, and moves on.
The audio sits in a separate system.
The admissions, the sequence, and the moments the other driver’s account contradicts itself never make it into a structured, citable record.

At arbitration, the contention becomes the adjuster’s word about what the statement said.

The evidence inventory that should be in every contention package hasn't changed in 15 years: recorded statements from both parties and any witnesses, the police report, scene photos and a diagram with points of impact, vehicle photos, and repair estimates. What has changed is how reliably that package gets assembled by an adjuster working their 40th file of the week.

Citing the wrong statute, or no statute at all

For most adjusters, finding the right state vehicle code section means a web search or a hunt through an internal intranet. A 20-year industry veteran recently called this workflow “scary.”

Multi-state books make it worse. An adjuster evaluating a rear-end accident in California one hour and a disputed-lane-change loss in Virginia the next must navigate entirely different negligence standards. Pure comparative, modified comparative with a 51% bar, contributory—they all start to look the same after dozens of claims. OR An adjuster may handle a claim in California one hour—where a driver who is 70% at fault can still recover damages—and a claim in Virginia the next, where 1% fault can eliminate recovery altogether. Keeping those rules straight across a multi-state book isn't easy.

The result is a contention opposing carriers and arbitrators can pick apart, and a settlement posture that gives up ground before the negotiation starts.

What an integrated liability workflow changes

The shift is from paper manuals, browser tabs, hand-typed summaries, and standalone scoring software to a single guided workflow that consolidates evidence, statutes, and assessment into one record. Verisk's Liability Navigator® is built around that shift. For APD, four connected capabilities make up the accident liability workflow, each one feeding the next from FNOL through the carrier-to-carrier call.

An API-driven recorded statements workflow	The adjuster uploads the statement. The platform transcribes it, populates the structured investigation questions, and feeds those answers into the liability assessment. The statement becomes data the assessment runs on.
Points-of-impact and interactive accident scene diagrams	Visual evidence reconstructs the physics of the loss. The multi-lane left turn becomes a 70/30 conversation backed by a diagram instead of a 100/0 default backed by a comment.
A curated statutory library, governed and current	The relevant vehicle code section surfaces next to the investigation question for that state. An Insurance Laws and Minimum Limits view shows the negligence rule for every state on one screen.
A suggested liability range with pros-and-cons negotiation points	The adjuster enters the carrier-to-carrier call already knowing the strong and weak parts of their case and what the opposing carrier will push on.

Most APD disputes resolve at that carrier-to-carrier call, before arbitration.

Video capture of the loss event is the next leap. When the footage shows the sequence, the liability split becomes self-evident, and some disputes never need to reach subrogation at all. The carriers with an integrated workflow today will absorb that shift faster than the carriers still piecing files together across systems.

For carriers weighing whether to build this in-house: Timelines stretch, model maintenance compounds, compliance validation gaps don’t close, and the interface degrades the moment IT priorities shift.

What it means for claims management

Settlement accuracy and consistency: Structured workflows force comparative fault to be evaluated rather than skipped. One sample client study revealed a 28-percentage point increase (from 4% to 32%) in applied liability when using Liability Navigator.

Subrogation recovery: More files get evaluated, so more files become recoverable. Subrogation is the only place claims operations make money; everywhere else is loss.

Span of control and on-the-job upskilling: Structured prompts act as a coaching layer. A two-year adjuster works through the same investigation questions a 20-year veteran would, and variance across the team narrows.

Audit and litigation defensibility: Each determination comes with documented rationale, statutory citations, and the underlying evidence—ready for QA review, regulatory examination, or a bad-faith allegation.

What the carriers at the forefront are doing differently

The carriers staying ahead give their adjusters a workflow that produces the same complete, statute-backed, evidence-supported contention package every time. The payoff happens weeks before any arbitration filing: In the 100/0 call your adjuster doesn’t default to, and in the file that gets referred for recovery instead of simply getting closed and paid.
