Litigation & Insurance Disputes (Quantum & Coverage Interface)
Litigation and arbitration support in BI matters means independent reconstruction of models, disciplined document review, and opinions that separate coverage questions reserved for the court from financial quantum within the expert’s competence.
Many BI mandates sit at the interface of coverage arguments and financial quantum - for example pandemic disease and access clauses post–[2021] UKSC 1, insurer repudiations, or multi-party supply chain failures. Experts model alternative coverage scenarios without usurping the court’s role on ultimate wording construction.
Where allegations concern unreasonable claims handling or systemic under-reserving, combined forensic and loss-adjusting credentials help tribunals assess industry practice alongside reconstructed quantum.

Frequently asked questions
What cases require a business interruption expert witness?
When insurers dispute quantum, policyholders rebut insurer models, BI proceeds to litigation or arbitration, or concurrent coverage and quantum scenarios need independent reconstruction.
How early should I retain a BI expert witness?
As early as possible - to advise on document preservation, critique opposing methodology, and shape the loss narrative before positions harden.
How do experts separate coverage from quantum?
Experts model financial outcomes under alternative coverage assumptions instructed by the parties while reserving ultimate wording construction to the court, documenting which questions are answered versus reserved.
