Third-Party Funding Reshapes Post-M&A Arbitration in Spain
Third-party funding is increasingly shaping the strategic landscape of post-M&A arbitration, according to discussions at the OPEN de Arbitraje 2026 conference held in Madrid. Practitioners and arbitrators examined how external capital is altering the calculus for claimants pursuing disputes that arise from share purchase agreements, earn-out clauses, and post-closing indemnity claims.
As reported by Iberian Lawyer, panelists framed third-party funding as a viable alternative for parties navigating the often-protracted and capital-intensive nature of M&A arbitrations. The discussion emphasized that funding agreements are no longer reserved for distressed claimants but are increasingly deployed by well-capitalized parties seeking to manage risk, free up balance sheet capacity, or align outside investors with the success of a claim.
Spain has emerged as one of Europe's more receptive jurisdictions for funded arbitration, with both the Spanish Court of Arbitration and the Madrid International Arbitration Center requiring disclosure of third-party funding arrangements. That regulatory clarity has helped institutional funders deepen their involvement in the Iberian market while giving counterparties greater visibility into the financing of claims.
The panel highlighted that post-M&A arbitration presents particular structural features that make funding attractive: claims tend to be discrete, liability-driven, and supported by extensive transactional documentation, all of which improve underwriting predictability. As funders refine their models for valuing M&A disputes, the conference signaled that capital is poised to play a more visible role in shaping which claims are pursued and how they are resolved.
