Warranty Claim Expert Witness Qualifications

Core Credentials

Warranty claim expert witnesses should hold ACA/FCA (ICAEW) qualification, ICAEW Forensic Accreditation, M&A transaction experience (ideally Big 4 or equivalent, warranting credibility in deal-value disputes), CPR Part 35 expert report history, and prior court acceptance in warranty and M&A dispute contexts.

M&A Experience Requirement

Warranty claim expert witnesses must understand M&A transaction mechanics, not just accounting. Prior advisory experience in deals (due diligence, completion accounts preparation, SPA negotiation support) gives credibility that pure expert witnesses lack.

The Inspired Education v Crombie [2025] Standard

Expert witnesses in warranty claims must use instructions consistent with standard definitions of market value, approach all evidence rigorously, and maintain genuine independence. They must not adopt a partial approach to sources and analysis.
