Fact-finding as Strategy: How Cross-Border Investigations Strengthen Latin America Arbitration

Juan Rodriguez May 12, 2026

Legal hubs, such as Miami and Atlanta, are becoming a preferred setting for hosting Latin American related disputes. Given the nature of political instability and the lack of legal certainty throughout the region and around the world, international arbitration has become the preferred mechanism for cross-border disputes and international litigation. Legal practitioners increasingly rely on leading arbitral centers to handle complex matters spanning infrastructure, energy, mining, finance, and technology. Yet, while arbitration practice has evolved and become increasingly procedural-based, the use of investigation methodologies to uncover facts and shape the legal strategy has lagged. In high-stakes disputes, that gap is not academic, but is factual and can materially affect outcomes.

That gap matters, and in many cases, it is outcome determinative. Unlike litigation in common law jurisdictions, arbitration typically offers limited discovery, narrower document production, and the inability to apply U.S.-style depositions and cross examination. In Latin America related matters, those limitations are often compounded by local legal traditions, procedural norms, limited access to public records, lack of transparency, and practical barriers to fact finding. In that environment, cross-border investigations should not be viewed as a peripheral service; it can be a core component of an effective arbitration strategy.

How Investigations Add Value at Every Stage of Arbitration

Investigative support can add value at multiple stages of an arbitration. In the pre-arbitration phase, investigators can help navigate vast amounts of the client’s own data, identify relevant witnesses, locate key evidence, and place fragmented information in the proper factual and commercial context. That early work can strengthen the investigative strategy, sharpen pleadings, and inform document requests. It also lays the groundwork for later-stage services, such as asset-tracing and forensic accounting, which are often far more effective when built on a strong factual base.

In our experience, across multiple matters, early-stage investigative work has directly informed forum strategy, including decisions around where and how to initiate proceedings. It helps to identify potential conflicts of interests, biases and predetermined judgements. It has also helped reshape document requests by identifying where relevant evidence is likely to exist, and where it is not, allowing counsel to move more precisely and avoid wasted cycles. Perhaps most importantly, it has surfaced critical facts, relationships, and contextual elements that would not have emerged through the arbitral process alone, particularly in jurisdictions where formal records are incomplete or do not reflect how decisions were actually made.

In several instances, these early insights have materially shifted case strategy and positioning before a tribunal is even constituted.

One of the most common, and costly, mistakes in arbitration is treating investigations as a reactive tool rather than a proactive one. By the time a tribunal is constituted, and document production begins, key opportunities to shape the factual record are often already lost. Early stage investigative work not only informs case strategy, but can also influence forum decisions, settlement posture, and the framing of claims and defenses. In cross border disputes, timing is not just a tactical consideration; it is often a determining factor.

Two Structural Challenges in Latin America Cross-Border Disputes

Cross-border arbitration in Latin America presents recurring challenges that often cannot be addressed through document production alone. A strategic investigative approach, particularly one that incorporates human intelligence, socio-political awareness and regional expertise, can materially improve a party’s ability to assess risk, develop claims, and pursue enforcement. In our work on Latin America related disputes, we repeatedly see two structural challenges:

Disputes frequently involve governments or state-owned entities, where transparency may be limited and key decisions are often politically sensitive, undocumented, or communicated through intermediaries. In these environments, decision making is frequently shaped outside formal records, making it difficult to reconstruct events through document production alone. In those matters, human source inquiries can be critical, not only to understand what happened, but to clarify why decisions were made and how they evolved in practice.
Layered holding companies, offshore vehicles, and nominee arrangements can obscure issues of control, liability, and damages. Early insight into beneficial ownership, asset location, counterparty solvency, and enforcement prospects can materially affect arbitration strategy and settlement leverage. It also contributes to building a sound award valuation strategy for later stages of any dispute.

Equally important is how investigative findings are developed and presented. In arbitration, credibility carries particular weight, and tribunals are often highly attuned to the provenance and reliability of evidence. Investigative work that is carefully sourced, legally obtained, and strategically integrated into the broader case narrative can enhance not only the strength of the underlying facts, but also the overall persuasiveness of a party’s position. Done properly, it allows counsel to move beyond inference and argument, and into demonstrable fact. It also allows for the identification, when necessary, of ideal expert witnesses to convert those facts into understated, yet devastating, evidence.

Regional Expertise as a Core Component of Arbitration Strategy

Regional experience matters: As Latin America related arbitration continues to grow in complexity, so too must the approach to fact development. Investigations should not be treated as a supporting function, but as a core strategic discipline, one that shapes claims, informs leverage, and, in many cases, determines outcomes. This requires experienced practitioners and investigators who understand arbitral proceedings, jurisdictional nuances, and can handle evidence and witnesses in sensitive and contentious circumstances. Firms like Guidepost Solutions, with dedicated cross-border investigations teams and deep operational experience across Latin America, help counsel and their clients bridge the gap between limited arbitral discovery and the factual record needed to prevail. In modern cross border disputes, experienced investigative support, with substantial regional expertise, is not a peripheral consideration, but a core strategic component.
