What Is Dispute Accounting?

Definition

Dispute accounting is a specialist branch of forensic accounting focused on the financial analysis, investigation, and quantification required to resolve legal disputes. It encompasses expert witness evidence, loss quantification, fraud investigation, asset tracing, business valuation in contentious contexts, and accounting advisory in litigation, arbitration, and alternative dispute resolution.

How It Differs from Regular Accounting

Regular accounting focuses on financial reporting, compliance, tax, and business advisory, the ongoing financial management of an organisation. Dispute accounting applies forensic investigative skills and accounting expertise specifically to resolve disagreements, analysing historical financial records with the rigour of a forensic investigation, producing court-admissible reports, and presenting findings under cross-examination.

What Dispute Accountants Do

• Quantify financial losses arising from breach of contract, fraud, or other commercial wrongs
• Investigate financial irregularities and suspected fraud
• Trace assets through complex transaction records
• Value businesses and shareholdings in contentious contexts
• Prepare CPR Part 35 compliant expert witness reports
• Attend court, arbitration, or tribunal to give oral evidence
• Act as Single Joint Expert (SJE) where directed
• Provide dispute advisory to assist parties in resolving disputes without litigation
• Review and rebut opposing expert accounting evidence

CPR Part 35 & Expert Duties

A dispute accountant instructed as an expert witness owes their primary duty to the court under CPR Part 35, not to the instructing solicitor or their client. This applies whether appointed jointly or by one party. Independence is the foundation of credible dispute accounting expert evidence.

Under CPR Part 35 and Practice Direction 35, the expert's overriding duty is to help the court on matters within their expertise. This duty overrides any obligation to the person instructing or paying them. The expert must provide opinions that are independent, objective, and unbiased, and must state the substance of all material instructions.

The leading authority remains *National Justice Compania Naviera SA v Prudential Assurance Co Ltd* ("The Ikarian Reefer") [1993] 2 Lloyd's Rep 68, which established that expert evidence should be independent, objective, and unbiased. Experts must not assume the role of advocate for their instructing party.

Where the court directs a Single Joint Expert (SJE) under CPR 35.7, both parties instruct the same expert jointly. The expert's duty remains to the court. Party-Appointed Experts (PAEs) are instructed by one side; their duty is identical, independence is not diminished by single-party instruction.
