International Arbitration Valuation Expert Witness UK

International arbitration valuation expert witnesses provide independent opinions on asset values in ICC, LCIA, ICSID, and other international arbitration proceedings seated in or involving UK parties. Investment treaty arbitration commonly applies fair market value for expropriation claims and DCF for operating businesses with established cash flow history.

The IBA Rules on Evidence govern expert evidence in international arbitration, typically with each party's valuation expert examined concurrently (hot-tubbing). Hot-tubbing places both parties' valuation experts before the tribunal simultaneously, with the tribunal directly comparing their methodologies and probing areas of disagreement in real time.

The Chorzow Factory standard requires full reparation for expropriation, typically measured as fair market value of the expropriated asset. Valuation experts must be thoroughly prepared for hot-tubbing format in international proceedings and able to defend their methodology under direct tribunal questioning.
