We provide skilled and specialist assistance in legal disputes and financial investigations, offering expert witness support in both civil and criminal courts, arbitration as part of ADR and expert determinations. Our matters typically involve assessment of quantum of losses and valuation.

We have vast in-house experience we draw upon to provide a swift response, often in the most complex and demanding of circumstances. We have worked with law enforcement agencies and lawyers worldwide and extensively throughout the UK.
