Operating across a variety of sectors, including energy, telecoms, and tourism, Pérez-Llorca‘s dispute resolution practice is adept at advising a range of blue-chip companies on the full gamut of contentious mandates. With expertise across litigation and arbitration, both domestically and internationally, and extensive experience representing clients before various commercial, civil, and arbitral courts, the team is well equipped to handle a range of high-profile cases, including post-M&A litigation, bilateral investment treaty disputes, and compensation claims. At the helm of the department is Félix J Montero, who stands out for his breadth of capabilities, which span civil and commercial litigation concerning corporate disputes and contracts, and international arbitration related to public concessions and investment disputes. Guillermina Ester is a key point of contact for post-M&A disputes and financial litigation, while Beatriz García focuses on antitrust damages.
