Automating Analysis of Proof-of-Loss Forms to Flag Irregular Submissions – Property & Homeowners and Specialty Lines & Marine

Fraud Analysts in Property & Homeowners and Specialty Lines & Marine face a relentless wave of sworn statements, receipts, and supporting files that must be scrutinized quickly and accurately. The proof-of-loss (POL) form sits at the center of this process—establishing the amount claimed, the basis for the loss, and the insured’s attestation. Yet, detecting omissions, inconsistencies, and patterns of abuse across thousands of POLs is a daunting, time-consuming task. Backlogs build, investigations start late, and leakage grows.

Nomad Data’s Doc Chat changes that equation. Doc Chat is a purpose-built suite of AI agents that reads entire claim files—including proof-of-loss forms, declarations, repair receipts, estimates, FNOLs, ISO claim reports, marine survey reports, bills of lading, and correspondence—and instantly flags incomplete, irregular, or suspicious submissions. Whether you’re searching for proof of loss fraud detection at scale, need to flag incomplete proof of loss AI-driven checks, or want to compare proof of loss to claim docs line-by-line, Doc Chat automates the intensive review work so Fraud Analysts can initiate early SIU workflows with confidence.

The Fraud Analyst’s Challenge: Why Proof-of-Loss Reviews Are So Hard in Property & Homeowners and Marine

For Fraud Analysts, the POL is both a roadmap and a minefield. In Property & Homeowners, POLs connect claimed amounts with damaged categories—Dwelling (Coverage A), Other Structures (Coverage B), Personal Property (Coverage C), and Additional Living Expense (ALE, Coverage D)—each with limits, sublimits, and exclusions that vary by form (e.g., HO-3 vs. HO-5) and by endorsements. In Specialty Lines & Marine, a POL may incorporate voyage details, cargo specifics, surveyor findings, and the applicable marine clauses (e.g., F.C.&S., Inchmaree), each of which alters coverage triggers and exclusions. The complexity multiplies when catastrophe events generate surges of POLs with similar narratives, when contractors flood carriers with templated repair receipts, or when marine losses span multiple jurisdictions and documentation formats.

Fraud patterns frequently hide in the seams: round-number claims that evade sublimits, replacement costs that ignore depreciation rules, invoices that pre-date the loss, serial-number mismatches on electronics inventories, or inconsistent descriptions across the POL, the FNOL, and the adjuster’s notes. In marine, misaligned cargo weights between the POL and the bill of lading, survey reports that contradict stowage conditions, or geography/time anomalies across port documents can signal problems. Each cue is subtle—and easy to miss when you are reading hundreds of pages under time pressure.

How Proof-of-Loss Reviews Are Handled Manually Today

Most carriers still rely on a manual, document-by-document approach. A typical Property & Homeowners workflow for a Fraud Analyst or SIU partner might look like this:

Open the POL packet and confirm sworn statement, signature, notary, and deadline compliance.
Reconcile claimed amounts with the declarations page limits, sublimits (e.g., jewelry, firearms, cash), deductibles (including hurricane/windstorm deductibles), and endorsements.
Cross-check line items against repair receipts, contractor estimates, serial numbers, and photos; review adjuster notes, inspection reports, and prior loss history (including ISO claim reports) for red flags.
Validate dates of loss versus invoice dates, delivery receipts, police/fire marshal reports, and utility statements (for occupancy).
Perform ad hoc online checks on contractors (licenses, business standing), vendors, and model numbers for plausibility.

In Specialty Lines & Marine, the stack is even more varied:

Compare POL details to the marine policy and endorsements (e.g., F.C.&S., Inchmaree, Sue & Labor), declarations, and voyage documents.
Cross-verify with bills of lading, manifests, packing lists, commercial invoices, certificates of origin, and surveyor reports of survey/Statement of Facts.
Check port call records, weather logs, AIS data, and general average documents when relevant.

These steps can consume hours per file and days for large batches—especially following a catastrophe (CAT) or a major marine incident. The cognitive load is intense, fatigue sets in, and subtle inconsistencies are often missed or discovered late. Surge events force triage, and many POLs get only cursory review until a larger problem surfaces.

Doc Chat: End-to-End AI Review That Reads Every Page and Flags What Matters

Doc Chat by Nomad Data ingests entire claim files—thousands of pages at once—and executes a comprehensive, repeatable analysis of every proof-of-loss submission. It is purpose-built for insurance documents and deploys your playbooks, policies, and SIU rules so Fraud Analysts see consistent, citation-backed findings in minutes. With Doc Chat for Insurance, you get real-time answers to questions like “What’s missing from this POL packet?” or “List every line item in the POL that lacks a matching receipt or serial number,” complete with links back to specific pages.

Unlike generic summarization tools, Doc Chat is built to do deep diligence on complex files. It traces every reference to coverage, liability, and damages across policies, endorsements, reports, and correspondence, so nothing critical slips through the cracks. In marine, it aligns POL details with the bill of lading, surveyor notes, and cargo documentation; in property, it reconciles the POL with declarations, ALE receipts, photographs, and contractor documents.

How It Works: From Intake to Anomaly Flags in Minutes

Here’s how Doc Chat operationalizes proof of loss fraud detection across Property & Homeowners and Specialty Lines & Marine:

High-volume ingestion and classification. Drag-and-drop POL batches or pipe them in from your claims system. Doc Chat classifies documents automatically: proof-of-loss forms, declarations, estimates, repair receipts, FNOL forms, ISO claim reports, photos, police/fire reports, marine surveys, bills of lading, manifests, and correspondence.
Completeness checks. The agent verifies signatures, notarization, sworn statements, dates of loss, policy numbers, insured/claim numbers, and deadlines. It immediately flags incomplete proof of loss packets and missing document types (e.g., missing serial-numbered receipts for high-value electronics, absent surveyor report for cargo damage).
Coverage alignment and sublimit validation. The AI cross-references all claimed categories with the declarations page, endorsements, and exclusions. It highlights when jewelry, firearms, cash, or business property claims exceed sublimits or fall under exclusions, and in marine, when damages conflict with clauses like F.C.&S. (war risk) or Inchmaree (latent defects).
Cross-document reconciliation. Doc Chat will compare proof of loss to claim docs end-to-end—matching line items to receipts, invoices to delivery records, and loss dates to device metadata, inspection notes, and survey timelines. For marine, it aligns cargo counts and weights across the POL, bill of lading, and packing lists, calling out discrepancies with page-level citations.
Pattern and anomaly detection. The system surfaces suspicious hallmarks: repeated narrative language across unrelated claims, implausible round-number patterns, invoice templates reused across different contractors, EXIF/photo inconsistencies, and chronology mismatches (e.g., invoices predating the loss).
Explainable outputs. Every finding links back to source pages for audit-ready defense. Fraud Analysts can dive from summary to the exact clause, receipt, or paragraph in one click.

This approach goes far beyond keyword search. As explained in Nomad’s piece “Beyond Extraction: Why Document Scraping Isn’t Just Web Scraping for PDFs”, the true value lies in AI’s ability to infer and apply your internal rulebook to messy, variable documents. Doc Chat institutionalizes your best SIU habits so every reviewer gets expert-level support.

Purpose-Built Fraud Signals: What Doc Chat Flags Automatically

Doc Chat encodes a library of fraud indicators tailored to Property & Homeowners and Marine. Examples include:

Inconsistent chronology: POL date of loss conflicts with invoice issue date, delivery receipts, or device EXIF timestamps; marine survey timestamps inconsistent with reported port calls.
Sublimit evasions: High-value personal property grouped as generic categories to bypass jewelry/firearms sublimits; business equipment misrepresented as personal household items.
Round-number patterns: Suspiciously uniform totals on receipts and estimates; identical tax/shipping line items across unrelated vendors.
Template reuse: Highly similar phrasing or formatting across multiple claims or contractors; same invoice numbering schemes, fonts, or logos used across different insureds.
Serial/model anomalies: Serial numbers that don’t match the product, model numbers discontinued prior to alleged purchase dates.
Contractor irregularities: Unlicensed or recently formed vendors issuing large invoices; mismatched addresses or phone numbers.
Photo and metadata checks: Duplicated photos across claims; EXIF data suggesting images were captured before the reported incident or at different locations than the loss site.
Marine cargo mismatches: Discrepancies between bill-of-lading counts and POL claims; stowage and damage narratives that contradict surveyor findings; cargo weights inconsistent with vessel’s manifest.
Policy trigger discrepancies: Claimed cause of loss not supported by weather logs (property) or by seaworthiness/stowage reports (marine).

These signal checks are configurable. Through the Nomad Process, we train Doc Chat on your playbooks so it mirrors your organization’s definition of red flags, thresholds, and escalation rules.

“Compare Proof of Loss to Claim Docs” in One Step

The most common Fraud Analyst request we hear is: “I need to compare proof of loss to claim docs without reading all of them.” Doc Chat is designed for that exact task. Ask the agent:

List all POL items over $2,500 and show whether each has a receipt, serial number, and photo. Provide page links.
Highlight all POL entries categorized as electronics and show if any exceed Coverage C or special limits.
Surface any mismatch between POL cargo counts and bills of lading, and summarize contradictions with the surveyor’s report.
Identify any language in this POL that matches other POLs in the last 60 days.

Each answer includes citations to the exact pages across the POL and the supporting documentation set, giving Fraud Analysts an immediate, defensible view of what’s wrong and why.

Nuances by Line of Business: Property & Homeowners vs. Specialty Lines & Marine

Property & Homeowners

Homeowners POLs frequently span categories like dwelling repairs, roof replacements, contents replacement, and ALE. Common failure points include:

ALE documentation: Missing leases/hotel receipts; inconsistent dates relative to habitability notices or inspection timelines.
Roofing/rebuild invoices: Invoices that reuse templates; mismatched shingle models; contractors with no permit pulls.
Contents claims: Lack of serial numbers for high-value items; store receipts that pre-date occupancy or contradict usage history.
Catastrophe surges: Highly similar narratives across neighbors; norm-breaking claim frequency for specific vendors.

Specialty Lines & Marine

Marine POLs introduce additional complexity: cargo conditions at loading/unloading, stowage plans, port calls, and coverage clauses unique to marine forms. Pitfalls include:

Document gaps: POLs that omit the bill of lading, packing list, or commercial invoice when claiming short or damaged cargo.
Clause conflicts: Claimed causes of loss excluded under F.C.&S.; mechanical breakdowns outside Inchmaree coverage; failure to mitigate under Sue & Labor.
Survey contradictions: POL narrative inconsistent with marine surveyor’s Statement of Facts (e.g., no evidence of wet damage where claimed).
Weight/count inconsistencies: POL tallies that exceed vessel manifest quantities or do not align with tare/gross/net weights.

Doc Chat encodes these nuances so Fraud Analysts can apply consistent scrutiny across both lines of business without reinventing their process each time.

What Changes with Doc Chat: From Days of Reading to Minutes of Answers

With Doc Chat, the review shifts from manual reading to targeted investigation. The agent produces:

A standardized POL integrity checklist showing which fields are present, which are missing, and any notarization/signature concerns.
A coverage alignment map tying each claimed item to the correct policy section, limit, sublimit, and deductible.
A reconciliation grid that shows a one-to-one match (or mismatch) between POL lines and receipts, photos, serials, or marine documents.
A red-flag summary with severity levels and recommended next steps (e.g., SIU referral, vendor verification, on-site inspection, surveyor follow-up).

This is not a black box. Every assertion is supported by page-level links so auditors, reinsurers, and regulators can verify the basis for each decision. Great American Insurance Group’s experience—summarized in “Reimagining Insurance Claims Management: GAIG Accelerates Complex Claims with AI”—highlights how page-linked explainability builds trust while slashing cycle time.

Business Impact for Fraud Analysts and SIU: Faster, Cheaper, More Defensible

Doc Chat’s automation creates compounding benefits across Fraud, SIU, Claims Intake, and Litigation support:

From Manual Drudge to Strategic Fraud Prevention: Example Scenarios

Property & Homeowners – Post-Storm Contents POL

Following a major wind event, the carrier receives 800 POLs over three days. One insured submits a contents POL listing high-end electronics totaling $28,750. Doc Chat instantly reconciles serial numbers and detects that two TV serials were discontinued models before the stated purchase date. It also notes the same vendor template appearing in three unrelated claims in the same ZIP code. The agent flags the file with “medium-high” severity, recommends contractor/vendor verification, and prompts an SIU referral. The Fraud Analyst clicks into citations, reviews the exact receipt pages, and launches inquiries within minutes of intake—deterring additional suspect submissions.

Property & Homeowners – ALE Overstatement

An insured claims six months of hotel stays for ALE. Doc Chat notices the habitability letter only covered 30 days, and utility usage indicates occupancy started earlier than claimed. With page-level links to the habitability notice, hotel invoices, and utility statements in the file, the Fraud Analyst reaches a defensible partial denial and prevents overpayment.

Specialty Lines & Marine – Short Shipment Claim

A cargo POL alleges 1,200 units short on arrival. Doc Chat cross-checks the POL, bill of lading, and packing list and flags a mismatch: the bill of lading states 10,000 units total, while the manifest shows an intermediate transshipment with consolidated pallets. The surveyor’s Statement of Facts indicates intact seals at arrival. Doc Chat recommends targeted questions for the shipper and survey review. The Fraud Analyst uses the citations to quickly assemble an SIU memo, accelerating resolution and reducing the risk of wrongful payment.

Integrating Doc Chat Into Fraud and SIU Workflows

Doc Chat meets you where you are. Start with manual uploads for a fast proof of value; expand to API-based integration with your core system for automated routing:

Intake: As POLs arrive, Doc Chat auto-classifies and performs completeness checks.
Triage: Cases with missing documents or high-severity anomalies are routed to Fraud Analysts; low-risk cases continue through standard adjudication.
Investigation: Fraud Analysts use Doc Chat’s Q&A to test hypotheses, gather page-cited support, and prepare SIU referrals.
Feedback loop: Outcomes feed the model’s preset rules and thresholds (under your control), refining future flags.

This transformation—moving from manual QC to AI-first review—is the pattern Nomad has seen across carriers. As described in “AI for Insurance: Real-World Use Cases Driving Transformation,” the greatest ROI often comes from automating document-driven steps that used to consume entire workdays.
