Automating Analysis of Proof‑of‑Loss Forms to Flag Irregular Submissions — Built for SIU Investigators in Property & Homeowners and Specialty Lines & Marine

Special Investigations Units (SIUs) in Property & Homeowners and Specialty Lines & Marine face a growing challenge: proof‑of‑loss (POL) forms are arriving in higher volumes, in inconsistent formats, and with increasingly sophisticated manipulation. Missing signatures, altered dates, mismatched totals, recycled narratives, and inflated inventories hide in plain sight across hundreds of pages of supporting documentation and declarations. Manually catching these irregularities is slow, costly, and error‑prone. The longer questionable submissions sit in queue, the more cycle time, loss‑adjustment expense, and leakage you incur.

This is exactly where Nomad Data’s Doc Chat changes the game. Doc Chat for Insurance ingests entire claim files—including sworn statements in proof‑of‑loss forms, declarations pages, estimates, invoices, repair receipts, photos, bills of lading, marine survey reports, and adjuster notes—and automatically performs completeness checks, cross‑document comparisons, and anomaly detection. SIU Investigators can ask plain‑language questions like “Compare proof of loss to claim docs for inconsistencies” or “Flag incomplete proof of loss AI triage results,” and get instant, page‑level citations. Early, accurate proof of loss fraud detection becomes standard, not exceptional.

Why Proof‑of‑Loss Review Is Different (and Harder) in Property & Homeowners and Specialty Lines & Marine

On paper, a POL is straightforward: a sworn, often notarized attestation that details the facts and the amount of loss. In practice, for SIU Investigators, POL analysis is a complex exercise in reconciling disparate data sources across a sprawling claim file. In Property & Homeowners, a single file can contain the FNOL, policy declarations, endorsements, mitigation invoices, contractor estimates (e.g., Xactimate), contents inventories, repair receipts, ALE receipts, photos, weather reports, police/fire reports, and correspondence. In Specialty Lines & Marine, the document stack grows to include hull & machinery surveys, bills of lading, packing lists, cargo manifests, surveyor certificates, AIS/GPS logs, master’s reports, letters of protest, and port authority notifications.

For an SIU Investigator, the nuance lies in connecting the POL to the correct coverage logic and factual record. Did the POL’s sworn amount reflect ACV vs. RCV correctly? Were depreciation and deductibles properly applied? Does the jewelry loss fall under a sub‑limit or schedule? Is a marine loss outside navigational limits or lay‑up warranties? Are equipment serial numbers on the POL inventory consistent with purchase documentation? Does the timeline claimed on the POL align with NOAA weather data, CCTV timestamps, or AIS tracks? Each question requires reading, cross‑referencing, and verifying across hundreds or thousands of pages.

How the Manual Process Works Today (and Where It Breaks)

Traditionally, SIU receives a referral or triggers a desk review when the adjuster sees something odd: the sworn proof arrives close to the deadline, the narrative reads like a template seen before, or receipts look off. The manual process typically includes:

• Opening the claim file and locating the proof‑of‑loss form, plus any earlier drafts.
• Verifying completeness: claimant identity, policy number, loss address/vessel, date of loss, cause, sworn amount, signature, notary, co‑insured/mortgagee details, and deadlines (e.g., 60 days for NFIP unless extended).
• Comparing sworn amounts to declarations limits, sub‑limits (e.g., theft of jewelry, firearms, fine arts), deductibles, and endorsements.
• Cross‑checking amounts and items on the POL against repair receipts, contractor estimates, mitigation invoices, and contents inventories.
• Reconciling narratives and timelines across FNOL notes, police/fire reports, photos, invoices, and correspondence.
• In marine claims, matching cargo condition and counts against bills of lading, packing lists, tally sheets, and surveyor reports; validating navigational limits, seaworthiness, and warranty compliance in policy documents.
• Documenting findings in a memo, flagging red flags, and recommending next steps (e.g., EUO, field investigation, or referral to ISO ClaimSearch).

Even at shops with excellent SIU playbooks, this work is tedious, slow, and variable. Adjusters and SIU analysts are human: fatigue sets in; time pressures and backlogs force triage; subtly altered dates or reused paragraphs slip by; and the same vendor invoice might reappear across unrelated claims without being caught. Seasonal surges and CAT events overwhelm capacity. Meanwhile, increasingly digital‑savvy fraudsters exploit gaps in consistency, hoping that one of many small discrepancies will go unnoticed.

Proof of Loss Fraud Detection: What SIU Investigators Need to See Early

Across Property & Homeowners and Specialty & Marine, the strongest SIU triage outcomes come from catching the following patterns as early as possible, and doing it consistently across every claim, not just the ones that “feel off.”

• Completeness gaps: missing or stale notarization; absent co‑insured or mortgagee signatures; incomplete itemization; missing photos or serial numbers; absent ALE documentation; lack of bills of lading or survey reports in marine cargo claims.
• Policy misalignment: sworn amounts exceeding limits or sub‑limits in declarations; misapplied deductibles; excluded causes of loss; navigational limit breaches; lay‑up warranty issues; territorial restrictions for specialty lines.
• Cross‑document mismatches: dates, times, addresses, hull IDs, VINs, IMO numbers, or SKUs that differ between the POL and supporting documentation (invoices, receipts, estimates, AIS logs).
• Recycled narratives and templates: repeated phrasing across unrelated claims or among multiple insureds/providers; identical item descriptions across different claimants.
• Mathematical inconsistencies: totals that don’t sum; quantity/price mismatches; depreciation/RCV/ACV miscalculations.
• Vendor anomalies: non‑existent contractors or repair shops; disconnected phone numbers; addresses that point to mail drops; invoices reused across different claimants.
• Timeline implausibility: repair receipts dated before loss; shipping documents inconsistent with port calls; weather‑dependent losses contradicted by NOAA data; long delays followed by last‑minute POL submissions.
• Geospatial contradictions (Marine): AIS track showing vessel outside covered waters at time of loss; yard estimates from ports not called; cargo shortage claims without tally sheet corroboration.

Manually catching all of this across thousands of pages and dozens of document types is a tall order. Yet it’s exactly the consistency you need for dependable proof of loss fraud detection.

How Nomad Data’s Doc Chat Automates POL Review End‑to‑End

Doc Chat is a suite of insurance‑specific AI agents purpose‑built to read entire claim files, extract facts, compare across documents, and answer questions with page‑level citations. For SIU Investigators handling Property & Homeowners and Specialty Lines & Marine, Doc Chat delivers a repeatable, defensible pipeline that transforms “read and reconcile” into “ask and verify.”

1) Ingest and normalize the entire claim file

Drag‑and‑drop or integrate via API. Doc Chat ingests the proof‑of‑loss forms, prior versions, declarations, endorsements, estimates, repair receipts, mitigation invoices, contents inventories, photos, police/fire reports, email threads, and adjuster notes. For marine, load bills of lading, packing lists, surveyor reports, captain’s log, AIS/GPS exports, port clearance docs, letters of protest, and shipyard estimates. The system handles mixed formats and wildly inconsistent layouts—the exact variability that breaks keyword scripts and templates. This capability is rooted in the distinct difference between web scraping and document inference; see our perspective in Beyond Extraction: Why Document Scraping Isn’t Just Web Scraping for PDFs.

2) Automated completeness checks

Doc Chat applies your SIU completeness criteria to the sworn POL: required fields, notarization and date checks, co‑insured/mortgagee alignment, inventory itemization granularity, required marine documents (e.g., tally sheets, surveyor certificates), and policy deadline adherence. If anything is missing or stale, you get an immediate checklist with citations to the pages where issues are detected or proof is absent. This is what SIU teams mean when they search “flag incomplete proof of loss AI”—it’s no longer a manual to‑do list.

3) Side‑by‑side policy and sworn amount reconciliation

Doc Chat automatically maps sworn amounts to limits, sub‑limits, deductibles, and endorsements found in declarations and policy forms. It will call out excess amounts, special coverage caveats (e.g., theft limits for jewelry), and RCV vs. ACV logic problems. Every conclusion links to the language that supports it, aligning with audit and regulatory expectations.

4) Cross‑document comparisons: Compare proof of loss to claim docs

Simply ask, “compare proof of loss to claim docs” and Doc Chat will identify mismatches across dates, SKUs, serial numbers, hull IDs, VINs, AIS timestamps, invoice totals, or line‑item descriptions. It also flags repeated text patterns across multiple claims, detecting recycled or templated narratives. Your SIU rules can add industry‑specific checks: lay‑up warranties, navigational limits, seaworthiness requirements, or cargo coverage triggers.

5) Anomaly and fraud pattern detection

We encode your SIU playbook into Doc Chat so the system recognizes red‑flag patterns you care about. For example: last‑minute POLs that maximize sub‑limits, inventory inflation after payment, vendors shared across high‑risk claims, or surveyor names repeatedly associated with exception‑heavy cargo claims. Insights can be pushed into your triage queue with confidence scores and next‑best actions.

6) Real‑time Q&A over the whole file

Ask “List all items over $5,000 on the POL and show corresponding repair receipts” or “Which POL line items lack photos or purchase documentation?” Doc Chat returns answers instantly with page citations, not just summaries, so SIU can verify with a click. This capability is illustrated in our client story here: GAIG Accelerates Complex Claims with AI.

7) Structured outputs for SIU workflows

Doc Chat outputs checklists, timelines, comparison tables, and referral memos in your required formats. It can populate fields in SIU case management, or export to your claims system (Guidewire ClaimCenter, Duck Creek, Origami Risk), and push entities to ISO ClaimSearch. This is not generic “summarization.” It’s a personalized, rule‑driven SIU process delivered in minutes, not days. For a broader perspective on why this kind of automation is the “goldmine” many teams overlook, see AI’s Untapped Goldmine: Automating Data Entry.

What Moves the Needle: Tangible Business Impact for SIU and Claims Leadership

Carriers adopt Doc Chat for POL analysis because it compresses time and reduces leakage while strengthening defensibility. The impact shows up across multiple KPIs.

Time savings and throughput

Doc Chat reviews massive document sets without fatigue. Clients have seen thousand‑page reviews drop from days to minutes, and 10,000–15,000 page cases summarized in under an hour, as discussed in The End of Medical File Review Bottlenecks. For SIU, that means triage, referral decisions, and EUO scheduling happen earlier in the claim lifecycle, reducing cycle time and backlog.

Cost reduction and optimized staffing

By automating repetitive checks, SIU Investigators spend more time on strategy and interviews, not on manual line‑by‑line reconciliation. Loss‑adjustment expense declines with fewer overtime spikes and less external vendor reliance for large reviews. One SIU analyst can confidently handle more cases without sacrificing quality.

Accuracy and consistency

Machines don’t get tired. Doc Chat applies your rules identically across every claim, pulling every reference to coverage language, sworn amounts, and damages. The result is fewer misses, better referrals, and stronger negotiation positions. In our broader work with claims organizations, we consistently see accuracy increase as volume and complexity rise, a point we elaborate on in Reimagining Claims Processing Through AI Transformation.

Early detection, lower leakage

When you catch irregular POLs in hours instead of weeks, you avoid overpayments and reduce the chances of entrenched litigation. Proactive detection of recycled narratives, fake receipts, or marine warranty breaches materially reduces leakage over time.

Deep Dive: Property & Homeowners Proof‑of‑Loss Automation with Doc Chat

Property files often turn on the intersection of policy language and meticulous document trail verification. Doc Chat operationalizes that intersection for SIU.

Typical Property & Homeowners documents Doc Chat handles for POL analysis include: the sworn proof‑of‑loss; policy declarations, endorsements, and sub‑limits; mitigation invoices; contractor estimates; repair receipts; contents inventories; ALE receipts and lease agreements; photographs; fire/police reports; weather data; adjuster notes; communications; and prior claims or loss run reports.

Doc Chat will, for example, reconcile a $78,500 sworn amount against Coverage A/B/C limits, depreciation, deductibles, and endorsements. It will flag that a $12,000 jewelry loss is capped by a $5,000 sub‑limit absent a scheduled endorsement; that depreciation was calculated on non‑recoverable items contrary to policy; or that ALE hotel receipts overlap with the occupancy period post‑repairs. It will highlight proof of loss fraud detection indicators like template paragraph reuse, identical line items across neighbors’ claims after a CAT, or an invoice for a contractor who doesn’t exist in business registries.

Deep Dive: Specialty Lines & Marine Proof‑of‑Loss Automation

Marine and specialty claims require additional diligence across documents like bills of lading, packing lists, tally sheets, cargo manifests, surveyor reports, class certificates, seaworthiness attestations, AIS/GPS tracks, logbooks, letters of protest, and port authority notices. Warranty and navigational issues loom large.

Doc Chat aligns sworn POL amounts to H&M or cargo coverage, navigational limits, lay‑up warranties, and territorial restrictions. It will flag where the vessel’s AIS shows operation outside insured waters at the time of loss, or where a cargo shortage claim lacks corresponding tally sheets. It will detect that surveyor language is identical to language used in other questionable claims, or that a hull repair receipt’s date precedes the alleged loss date. When you ask, “compare proof of loss to claim docs,” Doc Chat produces a discrepancy list with citations so SIU can decide whether to request an EUO, a port inspection, or a deeper vendor validation.

From Manual to Managed: What an SIU Day Feels Like With Doc Chat

Consider a typical scenario for a senior SIU Investigator:

You receive a referral on a homeowner’s water loss. The sworn POL is for $143,200, filed on day 59, with dozens of line items and a contractor estimate. Traditionally, you’d scan through everything, take notes, and compare policy terms, receipts, and photos by hand. With Doc Chat, you drop the entire file into the system and run your “POL Completeness & Consistency” preset. In minutes, you get:

• A completeness checklist noting missing co‑insured initials on the sworn statement and a notary seal that appears to be from a different county than the loss location.
• A policy reconciliation that flags a $10,000 jewelry sub‑limit and a $2,500 deductible that wasn’t applied in the POL math.
• A contents comparison showing four line items that lack repair receipts or purchase documentation and three items with identical descriptions and unit prices seen in two other recent claims.
• A timeline view noting that two invoices are dated before the reported date of loss, with direct page citations for verification.

Rather than spending hours reading, you spend minutes verifying and planning next steps. You launch a vendor verification workflow, schedule an EUO, and notify the adjuster of the deductible and sub‑limit issues. Your SIU memo is auto‑drafted from the findings, including citations to all relevant documents.

Security, Compliance, and Explainability

SIU work is audit‑sensitive and often escalates to litigation. Doc Chat is built for that reality. Every answer includes a link to the exact page(s) that support it, creating a transparent audit trail your compliance, legal, and reinsurance partners can trust. IT teams maintain control over access and data retention, and Doc Chat integrates with your existing systems with secure APIs. For more on how carriers have brought AI into regulated claims environments without sacrificing control or explainability, review our GAIG webinar recap: Reimagining Insurance Claims Management.

Implementation: Fast, Safe, and Aligned to SIU

Getting started is intentionally lightweight. During the first week, we run your real claim files through Doc Chat in a secure environment and calibrate outputs to your SIU standards. Your investigators use drag‑and‑drop to test “proof of loss fraud detection,” “flag incomplete proof of loss AI,” and “compare proof of loss to claim docs” presets while we refine rules and thresholds. In week two, we integrate with your claims systems so outputs flow straight into your SIU queue and case management tools. Most teams go from POC to live in 1–2 weeks.

Frequently Asked SIU Questions About Doc Chat

Can Doc Chat recognize notarization issues and missing signatories on POLs?

Yes. We train the system to check for notarization presence, date validity, jurisdiction anomalies, and missing co‑insured or mortgagee signatures. Output includes a completeness checklist with citations.

How does Doc Chat handle marine‑specific validations?

We configure agents to match sworn POLs with bills of lading, surveyor reports, packing lists, AIS/GPS logs, and warranty terms. It flags discrepancies and navigation/warranty breaches with links to the exact clauses or pages.

What about repeated or templated language across multiple claims?

Doc Chat detects recycled paragraphs, repeated item descriptions, and suspiciously identical invoices across claims, even when filenames differ. SIU can ask for a cross‑claim similarity analysis over any historical window.

Do we need data scientists to maintain it?

No. Nomad’s team configures and maintains Doc Chat for you. As your playbooks evolve, we update presets and rules. Our white‑glove service ensures continuous alignment with SIU priorities.

Will this replace SIU investigators?

No. It augments SIU by removing rote reading and reconciliation, so humans focus on interviews, strategy, and determinations. We advocate a “human‑in‑the‑loop” model with transparent citations that support audits and litigation.

Proof‑of‑Loss Automation in Action: A Composite Use Case

A regional Property carrier sees a surge of water loss claims after a winter storm. SIU suspects contractor‑driven inflation and recycled inventories. The team enables a Doc Chat preset: “POL Completeness & Cross‑Claim Similarity.”

Within minutes, Doc Chat:

• Flags incomplete sworn statements (missing mortgagee signature) and three notarizations dated after the submission.
• Reconciles sworn amounts to declarations and highlights sub‑limit violations for jewelry and firearms.
• Surfaces line items that recur across six unrelated claims, with identical unit pricing and descriptions.
• Identifies repair receipts that appear in two files with different claim numbers and insureds.
• Outputs a memo recommending EUOs and vendor verification for the contractor associated with five of the flagged claims.

In parallel, a Specialty & Marine account reports a cargo damage claim supported by a sworn POL. Doc Chat compares the POL to the bills of lading, packing lists, and surveyor report, noting that the alleged shortage is not reflected in tally sheets and that the vessel’s AIS indicates a route outside the policy’s navigational area on the reported date. SIU escalates for a field survey and initiates coverage discussions early, avoiding weeks of drift.

Beyond the First Win: Building a Durable SIU Advantage

Once SIU teams see Doc Chat catching irregular POLs quickly and defensibly, they expand the scope: proactive vendor pattern monitoring, cross‑claim network analysis, and continuous policy audit for post‑bind exposures. Because Doc Chat works across the entire claim file, it becomes the natural engine for standardized SIU triage. That standardization improves training, reduces variance, and helps protect against knowledge loss when veteran investigators retire.

And the economics compound. Faster, more accurate triage reduces leakage, improves reserves, and cuts external review spend. Adjusters and SIU report higher engagement because the work shifts from drudgery to strategy. As we noted in our exploration of medical file bottlenecks, once the reading burden disappears, organizations can finally focus on judgment and outcomes—the work humans do best. See: The End of Medical File Review Bottlenecks.
