Wald, Antunes, Vita e Blattner Advogados is a market leader when it comes to arbitration law. The firm’s reputation is in part thanks to Arnoldo Wald, who is widely considered one of the founding fathers of Brazilian arbitration law.

Led by founder Arnold Wald, the firm is often seen working on some of Brazil’s most complex disputes. Wald’s presence in the arbitration world is almighty, having helped introduce some of Brazil’s core arbitration laws that are in place today. He has also written a plethora of books on the subject and is regularly invited to address complex issues related to the practice in some of Brazil’s leading financial and business media. He maintains a busy practice and is still a hugely relevant figure. With that said, the firm has in recent years shifted its focus to present a much more modern look to remain in touch with the evolving market and younger lawyers are now earning greater visibility as he passes down his wisdom to them. The firm chose to celebrate its talent by promoting a senior associate to partner in the last year.

The firm tailors its approach to each case with careful precision. Its success rate is impressive, as sensitive cases are matched to teams that can craft thorough and creative arguments in the courtroom. Its lawyers are known for having a strategic vision, with in-depth knowledge that sweeps across a broad range of industries. Big-name clients the firm regularly advises JBS, Vale, Oi and Copel, among others.
