Arbitrator & Mediator | Forensic Accountant & Expert Witness
Shipping, International Trade, Banking & Finance Disputes

Dmytro Tupchiienko is a London-based arbitrator and mediator (FCIArb) and a forensic accountant/expert witness with over 25 years’ international experience advising on complex disputes and investigations. His practice emphasises shipping and maritime trade disputes, cross-border commercial and regulatory matters, and banking/finance-related claims where outcomes depend on careful analysis of documentary records, operational context, and financial evidence.

He is regularly instructed on matters arising from sanctions and geopolitical disruption, including war-risk and port disruption scenarios that affect vessel operations, cargo flows, counterparties, payment channels, and insurance coverage. As an expert witness, he prepares CPR-compliant reports and supports courts and arbitral tribunals with quantum, causation, and loss attribution in multi-factor disputes.

Arbitration & ADR Practice

Dmytro accepts appointments as arbitrator and provides mediation/ADR services in commercial disputes, with particular suitability for document-heavy matters requiring structured case management, clear procedural directions, and careful handling of financial and technical evidence. He brings a calm, analytical approach, aiming to narrow issues efficiently while maintaining procedural fairness.
