The Litigation & Arbitration team is a cornerstone of our Portuguese practice, working seamlessly with other MGRA divisions to tackle complex disputes across commercial, civil, tax, administrative and criminal arenas and deliver integrated solutions, thus ensuring every strategy is tailored to our clients’ objectives and risk profile.

We represent national and international clients in high-stakes tax controversies, shareholder and commercial contract disputes, competition and regulatory enforcement actions, and white-collar crime matters. From first-instance proceedings to appeals before the Supreme Court of Justice and the Supreme Administrative Court, our litigators manage the full lifecycle of each dispute, coordinating evidence collection, expert testimony and multi-jurisdictional cooperation under one roof.

Complementing our courtroom work, we design and execute bespoke alternative-dispute-resolution roadmaps. Whether in ad hoc or institutional arbitrations (CAC, ICC, ICSID) or court-annexed and private mediations, we pursue efficient, relationship-preserving outcomes, empowering clients to resolve conflicts swiftly and protect their reputations.

Beyond disputes, we pride ourselves on proactive risk-mitigation advice, running internal investigations, compliance reviews, strategic negotiations and pre-emptive settlements negotiations, that keep our clients ahead of potential claims.

As cross-border activity accelerates, our team is ideally placed to coordinate multi-jurisdictional litigation and arbitral proceedings, drawing on a global network of top-tier counsel.
