Litigation Support and Expert Witness

We provide litigation support to solicitors and barristers throughout the country.

Our forensic litigation support services are delivered more cost effectively and efficiently than many of the larger firms.

We at D V Mannion & Co bring commercial, financial and international expertise to bear on the litigation support problems we are asked to investigate and report on.

Our clients receive more direct involvement from us at a lower cost than they might receive from a larger accountancy firm.

Litigation and other disputes have the potential to interrupt your business, and it’s not only the threat of an unsuccessful outcome that hangs in the balance. Countless hours are often required in extracting evidence from complex financial records. Unravelling the information you need and presenting a reasoned, substantiated case takes time and expertise, as well as clear, objective advice.

The successful resolution of disputes and court cases is often dependent on forensic accounting expertise to produce reliable reports on the matters in dispute. The need for forensic accounting sometimes arise in investigations required by an individual or by private companies, banks or legal advisers.

Our work in these cases is to establish the facts and key issues.

We provide:

-Clear, concise reports on relevant financial matters and taxation consequences

-Professional expert witness services

-Advice as required in commercial and other disputes

Our forensic accounting skills and our experience of working with legal advisers improve the chances of a successful conclusion to the legal process for the recovery of assets or compensation.

Our approach

We focus on the core issues, we work to establish quickly what information is relevant, we establish the facts, and we then present our report in a timely and professional manner. Not all cases go to court, but we are always conscious that an investigation or dispute may end up there. We, therefore, produce a clear and concise report which anticipates likely scrutiny by advisers for the other side.
