Our team advises on quantum and other accounting or financial issues in commercial disputes, including acting as expert witness in litigation and arbitration.

We will support you at each stage of your dispute, bringing together technical and sector specialists across different jurisdictions if required, including financial services, energy, construction and technology.

We will advise on evidence required to support the quantum of the claim or to defend against the approach taken by the other party. This analysis can help you to make informed choices at the outset as to how best to approach the dispute.

Consulting expert: we can advise on the quality of evidence supporting the quantum of loss all stages of proceedings and the impact of any new evidence arising.
