Professional Negligence Forensic Expert Witness UK

Professional negligence claims require forensic expert evidence to establish both the standard of care applicable to the profession and the resulting financial loss. The forensic discipline engaged depends on the profession alleged to have been negligent: forensic accountants for accountant, auditor, or financial adviser negligence; digital forensics experts for IT consultant or software developer negligence; and forensic engineers for structural, civil, or technical engineering negligence.

In all professional negligence cases, the forensic expert must opine on the standard of care, what a reasonably competent professional in that field would have done, and the but-for counterfactual loss caused by the breach. The SAAMCo principle (South Australia Asset Management Corp v York Montague Ltd) limits damages to losses within the scope of the professional's duty, and forensic experts must address this limitation when quantifying loss.

Expert reports that fail to address SAAMCo are vulnerable to challenge and may result in significant reductions in recoverable damages. Forensic experts must distinguish between losses caused by the negligence and losses that would have occurred regardless of the breach. This requires careful but-for analysis and, in complex cases, scenario modelling to isolate the impact of the negligent conduct.
