A member of the FERRERE Litigation and Arbitration team, Soledad Díaz focuses on cross-border investment, commercial and corporate dispute resolution, typically for international clients.

She regularly advises on arbitration matters (under ICC, ICSID, ICDR and other rules) and on matters of jurisdiction, arbitration clauses, and recognition of awards. She also regularly advises on investment disputes and on alternatives for structuring foreign investments under BITs signed by Uruguay.

She has represented clients in important construction, energy and corporate disputes, both in arbitration and litigation.

Her recent experience includes advice to the main contractor for a combined cycle power plant in ICC and related judicial proceedings and to the main contractor for a pulp plant in an ICC proceeding against the project’s owner and subcontractors, and to the main contractor for a cellulose plant in an ICC proceeding against the project owner. She has also acted as counsel in international arbitrations related to gas production and distribution against governments and government corporations, and in investment arbitrations, including one for over 3 billion dollars deriving from frustration of a mining project in Uruguay.

In recent years she represented clients in disputes related to construction of wind farms and biomass facilities, and in arbitrations and actions for provisional remedies in the hotel industry.

She also has experience in expropriation disputes, injunctions, actions for access to public information and provisional remedies, as well as in trademark and antitrust actions (such as the dispute over rebroadcast rights for the 2010 World Cup of Soccer in South Africa, and the conflict on free competition in telecommunications at the country’s main airport).

She has broad experience in bank-related disputes. Since 2005 she has been a member of the team defending international financial institutions in over 50 claims and two ICC arbitrations arising out of the 2002 banking crisis in Uruguay, for an amount in excess of 1.6 billion dollars.

She also successfully represented banks in customer claims deriving from the Bernard Madoff fraud and from the 2008 financial crisis.

She has also published numerous articles in Uruguay and abroad on procedural law, arbitration, international commercial litigation and bankruptcy. She wrote the “Evidence” Section of the Commentary on the National Procedural Code on which she worked with Professors Santiago Garderes and Gabriel Valentín (published by La Ley, Thomson Reuters, 2012).

In 2012 she was a Research Associate at Queen Mary University of London (Centre for Commercial Law Studies). In 2013 she was awarded a doctoral scholarship by The Hague Academy of International Law.
