How expert accounting evidence is prepared for major global proceedings.

United Kingdom Forums | CPR Part 35 & CrimPR Part 19

Overriding Duty to the Court

Under CPR Part 35, a financial expert witness owes an overriding duty to the court that takes precedence over any obligation to the instructing party. Expert opinions must be objective, unbiased, and confined to areas of genuine expertise.

Expert Declaration & Statement of Truth

Reports must follow Practice Direction 35, including a formal expert declaration, statement of truth, and confirmation that the expert understands their primary allegiance is to the court rather than the instructing firm.

Single Joint Expert vs Adversarial Proceedings

Single joint expert (SJE) instructions require neutral joint frameworks and transparent scope. In adversarial proceedings, experts must disclose all assumptions, data limitations, ranges of opinion, and instructions received.

Daubert Validation Tests

Application of Daubert gatekeeping criteria to forensic accounting methodology: testability, peer review, known error rate, general acceptance, and reliable application to the facts of the case.

FRCP Rule 26 Disclosure Requirements

Written expert reports under Federal Rule of Civil Procedure 26 must include qualifications, compensation, prior testimony, and a complete statement of opinions with bases and data relied upon.

Methodological Defensibility

Methodologies must be documented, peer-reviewable, and clearly separated from factual findings and opinion testimony.

International Arbitral Tribunals | IBA Rules on the Taking of Evidence

Party-Appointed Expert Reports

Reports in cross-border commercial arbitration must summarize instructions, assumptions, methodology, and opinions with sufficient clarity for tribunals and opposing parties under IBA Rules.

Tribunal-Appointed & Joint Experts

Tribunal-appointed experts must maintain independence. Joint expert processes require structured disclosure and transparent handling of supplementary instructions.

Multi-Jurisdictional Asset Tracing

Many international matters involve overseas entities and banking chains. Forensic work must document chain of custody, jurisdictional limitations, and the evidential weight of third-party records obtained abroad.
