Foreign counsel can lead and conduct arbitrations seated in Brazil without local bar admission, though court-facing steps like award enforcement require a lawyer registered with the Ordem dos Advogados do Brasil (OAB), according to guidance published by Global Law Experts.
Here is why that matters for international legal teams. While cross-border commercial contracts increasingly rely on neutral arbitral forums, matching foreign procedural strategy with domestic statutory rules defines whether an award survives judicial scrutiny.
The starting point for any foreign counsel arbitration analysis in Brazil is the Brazilian Arbitration Act (Lei nº 9.307/1996), which was subsequently amended by Lei nº 13.129/2015. This legislative framework establishes arbitration as an autonomous mechanism for resolving disputes over freely disposable patrimonial rights. Nothing in the statute conditions a party's choice of representative on membership in the local bar.
Arbitration remains a private, consensual process. The freedom of parties to organize their own proceedings extends to selecting who speaks for them before the tribunal. Leading chambers administering arbitrations seated in Brazil address representation through powers of attorney and proper mandates rather than nationality or local licensing.
Where parties select institutional rules such as those of the International Chamber of Commerce, the focus stays on whether a representative holds proper authorization. Foreign lawyers and Brazilian lawyers frequently appear side by side as co-counsel in the same proceedings.
Managing Powers of Attorney and Procedural Formalities
Even though foreign counsel may act freely within the arbitral tribunal, the authority to represent must be evidenced correctly. Defective powers of attorney or improperly legalized documents create avoidable delays.
For arbitrations seated in Brazil, the power of attorney should cover both the arbitral mandate and foreseeable court-facing steps. Essential fields include full corporate identification of the principal, explicit powers to commence and defend the arbitration, and authority to instruct local counsel.
A power of attorney executed abroad generally requires authentication before acceptance in Brazil. Because Brazil is a party to the Hague Apostille Convention, signatures notarized in member states receive a single certificate without consular steps.
Documents in a foreign language intended for Brazilian courts require translation into Portuguese by a sworn public translator. For the arbitration itself, the procedural language of the proceedings governs submissions.
When Local Counsel Becomes Mandatory
The central decision in any foreign counsel strategy is determining where arbitral advocacy ends and judicial advocacy begins. Under the Advocacy Statute (Lei nº 8.906/1994), representation before state courts is strictly reserved for lawyers registered with the OAB.
The moment a dispute requires appearing before a Brazilian state court or superior court, a hybrid counsel model is required. But there is a clear division of labor across different stages of a dispute.
| Task or Forum | Can Foreign Counsel Act Alone? | Practical Recommendation |
|---|---|---|
| Arbitral hearings before the tribunal | Yes | Ensure the power of attorney meets institutional requirements |
| Institutional filings and correspondence | Generally yes | Use Portuguese translations where required by rules |
| Interim relief before a state court | No | Retain local counsel or co-counsel empowered for court |
| Recognition and enforcement of awards | No | Retain local counsel experienced before the Superior Tribunal de Justiça |
| Annulment or setting-aside proceedings | No | Coordinate litigation strategy with OAB-registered local counsel |
| Evidence requiring judicial cooperation | No | Engage local representation to handle letters rogatory |
Enforcing a domestic award or recognizing a foreign award requires judicial proceedings before the Superior Tribunal de Justiça. Similarly, urgent injunctions and annulment applications demand local court representation.
Practitioners typically utilize three engagement models. These range from engaging foreign lead counsel with retained local co-counsel from the outset to instructing local lawyers solely for discrete court steps.
