Third-Party Funding & Costs in International Arbitration

Third-party funding can change how an international arbitration is financed, managed and perceived without changing the underlying dispute. It can raise questions about disclosure, conflicts, party control, confidentiality, adverse-cost exposure and the practical implications of an award across the rules, seat and procedural circumstances that apply. Costs are likewise more than a final accounting exercise. Budgeting, institutional advances, security for costs, cost submissions and settlement decisions may affect the procedural path from the outset. This page provides a global orientation to those connected questions; it does not endorse a funding model, predict a tribunal decision or advise on any particular arrangement.

The starting point

Make the next decision with the commercial context in view.

A funding discussion is best treated as one part of the dispute architecture, rather than a standalone finance decision. The applicable arbitration agreement, institutional rules, seat law, any mandatory disclosure framework, proposed funding terms, party resources, likely cost exposure and the tribunal’s powers may each matter. The 2022 ICSID Arbitration Rules, for example, expressly address third-party-funding notice, security for costs and cost decisions, while the ICC Rules require prompt disclosure of the existence and identity of a qualifying funder to support arbitrator independence and impartiality processes.[1][2]

How we help

The work around the decision.

Clear legal workstreams for a defined commercial question, coordinated with the people, documents and local inputs the matter requires.

Funding-option and objective mapping.

Identify the commercial objective, likely stages, budget assumptions, capital needs and decision rights that may shape whether funding, insurance, self-funding or another arrangement merits further assessment.

Agreement review and funding-term interface.

Examine proposed funding terms alongside the arbitration agreement, institutional rules and applicable law, including control, termination, reporting, confidentiality, settlement authority and recovery provisions.

Disclosure and conflict-risk planning.

Map timing, recipients and content of any required or prudent disclosure, while considering arbitrator conflicts, changes in ownership or control, and the need to keep information current as the proceeding develops.

Security-for-costs assessment.

Frame the evidential and procedural questions that may arise where security is sought or resisted, including ability and willingness to meet a potential costs order, access to the claim and the relevance of funding arrangements.

Costs strategy and procedural budgeting.

Develop a disciplined view of institutional advances, tribunal and expert costs, legal expenditure, reporting cadence, cost submissions and the assumptions that may affect settlement or hearing decisions.

Privilege, confidentiality and information governance.

Consider how sensitive documents, legal advice, work product and data may be shared with a prospective or actual funder without assuming that confidentiality or privilege has the same treatment in every relevant forum.

Settlement, award and recovery alignment.

Test how consent rights, return structures, enforcement costs, adverse-cost liabilities, settlement mechanics and post-award priorities may interact, without presuming a particular recovery or allocation result.

Context for the decision

The facts and records that shape the route.

The appropriate route depends on the parties, markets, documents, technology or assets involved, and the legal frameworks that may apply. A structured record helps keep the commercial question, evidence, ownership and specialist inputs aligned without assuming that one jurisdictional framework supplies every answer.

What should be assessed before a funding arrangement is discussed in detail?

The arbitration agreement, rules, seat, dispute stage, estimated spend, expected evidence, decision timetable and potential adverse-cost exposure are useful starting points. So are the proposed funder’s role, termination rights, information needs and any settlement or control provisions. These questions should be tested against the specific arrangement and procedural setting, not reduced to a standard term sheet.

Must funding be disclosed in every international arbitration?

There is no single universal answer. Disclosure can turn on the agreed rules, the version in force, tribunal directions, the seat and any applicable statutory framework. ICSID and ICC each contain published disclosure provisions, but their triggers and mechanics are not interchangeable.[1][2] A party should identify the operative framework and consider changes to the funding information over the life of the arbitration.

Does third-party funding mean that security for costs will be ordered?

No. The presence of funding is not a universal rule or outcome determinant. In the ICSID framework, a tribunal considers all relevant circumstances, including a party’s ability and willingness to comply with an adverse costs decision, the effect of security on the ability to pursue the case, party conduct and evidence concerning funding.[1] Other frameworks may differ, and the facts and tribunal directions remain important.

Questions, not prescriptions

What may matter.

These questions are general information intended to help decision-makers frame an initial discussion. The applicable position depends on the facts, current law, governing documents and relevant jurisdictions.

What should be assessed before a funding arrangement is discussed in detail?

Must funding be disclosed in every international arbitration?

Does third-party funding mean that security for costs will be ordered?

Can funding costs be recovered from the other party?

That question requires a careful reading of the applicable rules, law, cost standard and tribunal discretion. Institutional rules may identify categories of arbitration costs and factors for allocating them, but they do not create an automatic right to recover every financing expense. The funding agreement, submissions, procedural history and the tribunal’s approach can all be relevant to an eventual costs decision.

Begin with context

Put the decision into focus.

For an initial conversation, share only high-level, non-confidential context about the relevant business decision, markets, parties, documents and timetable. Do not send confidential, privileged, personal or time-sensitive material through a website enquiry.
