7.3 Fraud Detection, SIU & Subrogation Procedure

Key Takeaways

  • Insurance fraud is classified into soft fraud (opportunistic exaggeration of legitimate claims) and hard fraud (deliberate fabrication of losses), requiring adjusters to recognize specific behavioral and operational indicators.
  • Special Investigation Units (SIUs) specialize in fraud detection, leveraging advanced surveillance, ISO ClaimSearch database cross-referencing, and Examinations Under Oath (EUO).
  • Connecticut law mandates that insurers report suspected fraudulent claims to the Connecticut Insurance Department (CID) Fraud Bureau and law enforcement, backed by statutory immunity under C.G.S. § 38a-826.
  • Subrogation allows an insurer to recover paid claim expenses from negligent third parties, incorporating salvage recovery offsets and strict loss reserving techniques (case reserves and IBNR).

7.3 Fraud Detection, SIU & Subrogation Procedure

Core Principle: Insurance fraud inflates premiums for the honest public and undermines financial stability. Claims adjusters serve as the first line of defense, recognizing fraud indicators, escalating suspicious files to Special Investigation Units (SIU), and fulfilling Connecticut statutory reporting mandates. When claims are caused by third-party negligence, adjusters must aggressively pursue subrogation and salvage recovery to offset insurer losses and restore insured deductibles under the make-whole doctrine.


1. Understanding Insurance Fraud: Soft Fraud vs. Hard Fraud

Insurance fraud encompasses any intentional deception committed against an insurer to secure improper financial payout.

Categorization of Fraud

  • Soft Fraud (Opportunistic Fraud): Occurs when a policyholder or claimant has a legitimate loss but intentionally exaggerates or inflates the value of property damage, medical expenses, or lost wages to receive a higher settlement. Example: Adding pre-existing damage to a collision claim.
  • Hard Fraud (Premeditated / Fabricated Fraud): Occurs when a person deliberately plans, executes, or fabricates an entirely fake loss to collect insurance proceeds. Example: Staging an auto accident, committing arson to collect property insurance, or reporting a non-existent burglary.

2. Red Flags of Fraud Across Claim Types

Adjusters must maintain high vigilance for red flags—behavioral, financial, or situational patterns that suggest potential fraud. While a single red flag does not prove fraud, multiple indicators require referral to specialized investigators.

Red Flags Matrix by Claim Category

Claim TypeCommon Operational & Behavioral Red Flags
Property ClaimsLoss occurs shortly after policy inception or limit increase; claimant possesses handwritten, suspiciously neat receipts; claims for expensive luxury items inconsistent with claimant income; fire origin shows multiple simultaneous points of origin or accelerant traits; property was heavily over-insured or listed for sale prior to loss.
Auto ClaimsAccident occurs late at night in secluded areas with no independent witnesses; vehicle damage does not align with described crash dynamics; all passengers consult the same medical provider or attorney immediately; hand-delivered claim notices; phantom vehicle allegedly caused crash; vehicle title transferred recently.
Casualty / InjurySubjective soft-tissue injuries (e.g., whiplash) with extensive medical treatment; claimant resists returning to work despite light-duty availability; medical bills show identical treatment dates and billing codes across multiple claimants; history of frequent prior injury claims.

3. Role & Operation of Special Investigation Units (SIU)

A Special Investigation Unit (SIU) is a specialized department within an insurance company dedicated to investigating suspected fraud, uncovering organized fraud rings, and supporting criminal prosecutions.

Core SIU Tools & Tactics

  • ISO ClaimSearch Database: Cross-referencing nationwide insurance databases to identify prior loss histories, multi-carrier claims, and duplicate injury claims filed across different companies.
  • Surveillance: Conducting discrete physical or digital surveillance to verify claimed physical disability or property loss claims.
  • Background & Financial Audits: Reviewing public records, bankruptcy filings, credit reports (where legally permissible), and criminal history.
  • Examinations Under Oath (EUO): Conducting formal, recorded depositions where legal counsel questions the insured under oath regarding claim discrepancies.

4. Connecticut Mandatory Fraud Reporting & Statutory Immunity

Connecticut maintains strict statutory requirements to combat insurance fraud under C.G.S. § 38a-826.

Statutory Reporting Requirements

  • Mandatory CID Reporting: Insurance companies and adjusters who suspect, or have reason to suspect, that a fraudulent insurance claim is being made must report the file to the Connecticut Insurance Department (CID) Fraud Bureau within designated statutory timeframes.
  • Law Enforcement Notification: Cases involving hard fraud, arson, or organized crime must be reported to state or local law enforcement agencies and state's attorney offices.

Statutory Immunity Protection (C.G.S. § 38a-826)

To encourage aggressive fraud reporting, Connecticut law provides statutory immunity from civil liability (such as libel, slander, or malicious prosecution suits) to insurers, adjusters, and employees who furnish information regarding suspected fraud to regulatory or law enforcement bodies, provided the report is made in good faith and without malice.


5. Subrogation Workflow & Mechanics

Subrogation is the legal process by which an insurance company, after paying a covered loss to its insured, steps into the shoes of the insured to pursue financial recovery from the negligent third party who caused the loss.

The Subrogation Lifecycle

  1. Identification of Liability: Identifying third-party negligence during initial claim investigation (e.g., a defective product manufacturer, a negligent driver, or a liable landlord).
  2. Preservation of Rights: Ensuring policy contracts explicitly preserve subrogation rights and instructing the insured not to sign third-party liability releases.
  3. Subrogation Demand: Submitting a formal demand package to the tortfeasor's insurer, including proof of payment, investigation reports, photos, and expert findings.
  4. Negotiation & Arbitration: Resolving subrogation disputes through direct negotiation or inter-company arbitration (such as Arbitration Forums, Inc.).

The Make-Whole Doctrine & Deductible Reimbursement

Under Connecticut insurance principles, when an insurer recovers subrogation funds from a third party:

  • Deductible Priority: The insured is entitled to be made whole first. The insurer must refund the insured's deductible out of the subrogation recovery before the insurer retains funds for its own loss payout, unless pro-rata allocation is mandated by contract or specific regulation.

6. Salvage Recovery & Management

Salvage refers to the damaged property or vehicle that an insurer takes ownership of after paying a total loss claim.

Salvage Workflow

  • Total Loss Settlement: Upon paying the full actual cash value (ACV) of a destroyed vehicle or damaged property, the insurer acquires legal title to the salvage.
  • Title Transfer: Obtaining a statutory Salvage Certificate or Salvage Title from the Connecticut Department of Motor Vehicles (DMV).
  • Auction & Offset: Selling the salvage at public auction or to licensed auto recyclers, applying net proceeds to reduce the gross claim loss.

7. Loss Reserves Accounting: Case Reserves vs. IBNR

Establishing accurate loss reserves is a statutory requirement to maintain insurer solvency and reflect financial liabilities accurately.

Types of Reserves

Reserve CategoryDefinition & Application
Case ReservesIndividual reserves set aside by the adjuster for a specific, identified claim to cover expected future indemnity payments and claim defense expenses (ALAE).
Bulk / Unallocated ReservesGeneral reserves established for groups of smaller, routine claims where individual reserving is inefficient.
IBNR (Incurred But Not Reported)Actuarial reserves set aside for losses that have occurred but have not yet been reported to the insurer (e.g., latent occupational diseases or unreported accidents).
