Equipment Breakdowns, Subrogation & expert witness

Don’t Leave Money on the Table — Subrogation in Complex Technical Losses

Subrogation is one of the most effective tools insurers have to reduce leakage — yet in complex technical losses, the opportunity is routinely missed. Here is where it hides, and what it takes to find it.

Evidence preservation and forensic cause analysis are what turn a technical loss into a recoverable one.

Subrogation is one of the most effective tools insurers have to reduce leakage and recover dollars that should never remain on the books. Yet in complex technical losses — equipment breakdown, electrical failures, fire and explosion, and BESS thermal events — subrogation potential is often missed.

Not because the claim wasn’t handled well.
Not because the adjuster didn’t ask the right questions.
But because these losses require a level of technical investigation that goes beyond traditional claims workflows.

Where subrogation hides in technical losses

In EB, electrical, fire/explosion, and BESS incidents, causation is rarely simple. Responsibility often sits behind:

  • Component-level failures
  • Manufacturing defects
  • Improper installation or commissioning
  • Maintenance gaps
  • System integration issues
  • Third-party workmanship
  • Design or engineering decisions
  • Vendor or contractor actions
  • Battery management system anomalies
  • Thermal propagation pathways

These are not “desk-review” findings. They require forensic cause analysis, evidence preservation, and technical interpretation of failure modes.

Why this matters

When root cause isn’t properly established, subrogation opportunities disappear.

When evidence isn’t preserved, recovery becomes impossible.

When technical findings are incomplete, legal teams lack the foundation to pursue responsible parties.

This is where Mission Critical Forensics strengthens outcomes.

Our role in supporting subrogation

  • Forensic cause analysis for EB, electrical, fire/explosion, and BESS losses
  • Evidence preservation and chain-of-custody management
  • Failure mode and mechanism analysis
  • Technical documentation that supports legal recovery
  • Clear, defensible reporting that withstands scrutiny
  • Collaboration with adjusters, SIU, and counsel to identify responsible parties early

Our work doesn’t replace claims handling — it enhances it.

It ensures technical losses don’t close prematurely, and that recoverable dollars aren’t left behind.

The cost of not investigating

Every missed subrogation opportunity is:

  • Avoidable leakage
  • Unnecessary loss ratio pressure
  • Reduced competitiveness
  • Diminished financial performance

As technical losses increase — especially BESS and electrical failures — subrogation is no longer optional. It is strategic.

If your organization handles complex technical losses and wants to strengthen subrogation outcomes, our subrogation and expert witness support is ready to help your team.
