International Arbitration Funding: Investment Treaty and Commercial Disputes

How funders approach ICSID, ICC, and LCIA proceedings, annulment risk, and award enforcement.

International arbitration funding supports claims resolved through arbitration that crosses borders, including both international commercial arbitration between private parties and investor-state disputes between investors and sovereign states. These proceedings, administered under the rules of institutions such as the ICC, the LCIA, and, for investment treaty claims, ICSID, can involve very substantial sums and span many years. Their scale, duration, and complexity make them a significant, if specialized, category of litigation finance.

Investor-state arbitration presents distinctive features. These claims arise under bilateral or multilateral investment treaties that protect foreign investors against unfair treatment, expropriation, and other state conduct, and they are often administered under the ICSID Convention. The sums at stake can be enormous, but so are the risks: jurisdiction is frequently contested, proceedings can take many years, and ICSID awards are subject to a distinctive annulment process that can unwind an award on limited grounds. Funders model these risks explicitly.

Commercial arbitration between private parties is more analogous to litigation but retains arbitration's particular characteristics. Proceedings are confidential, the parties select arbitrators, and the seat of arbitration determines the supervisory court and the law governing the arbitration. The seat affects the availability of interim relief and the grounds on which an award can be challenged or set aside. Funders evaluate the strength of the claim, the governing law, the seat, and the procedural posture in assessing a commercial arbitration matter.

Enforcement is often the decisive consideration. A favorable award has value only if it can be collected, and enforcement depends on locating the respondent's assets and pursuing recognition in the relevant jurisdictions. Commercial awards benefit from the New York Convention's broad enforceability across more than 170 states, while enforcement against a sovereign raises immunity issues that can complicate collection. Funders assess the respondent's assets and the realistic enforcement path before committing capital, since an uncollectible award is worth little.

Criterica Capital funds international commercial and investment treaty arbitration where the claim is strong, the quantum substantial, and the respondent capable of satisfying an award, with underwriting informed by outcome data drawn from 106M+ court records and enforcement analysis tailored to the relevant jurisdictions.
