Our expert witness services can enable the resolution of disputes without litigation, or provide highly valuable, informed opinions in court cases. Independent and reliable, the expertise and professionalism our accountants bring to each case provide our clients with confidence even in difficult situations.
What does an expert witness do?
Where there has been a contractual dispute, our accountants act as expert determiners. They meet with both parties to gain an understanding of the case and gather information, and then provide an independent opinion on what they believe is the best solution.
During both civil and criminal court cases involving accounting issues, the judge may require an expert witness to provide information or analysis. This may include valuing a business, preparing accounts, or determining the tax consequences of selling or transferring assets.
In some cases, each party has their own expert, while in others, a single joint expert is appointed to deal with the whole case. An expert witness produces a full written report in compliance with the relevant legal frameworks, including Family Procedure Rules. Their judgments, though not legally binding, are a highly valued supporting opinion in the cases they work on.
