Third-party funding of international arbitration is a recent phenomenon but one that is certainly here to stay. Once the old prejudices regarding the financial participation of lawyers in the result of the proceeding have been abandoned, the increasing participation of third parties in funding litigation, whether it be arbitration or court proceedings, is a circumstance to keep in mind in our arbitration or forensic practice. Litigation has become a financial asset and, consequently, a series of relationships arise when analysing the impartiality and independence of arbitrators. As always, all proceedings must be presided over in good faith. One of its fundamental elements is the arbitrators’ and parties’ duty of disclosure of their third-party funding to avoid conflicts of interest.
