Where Advocacy Meets Business

“I work hard at building strong ties with our clients and meeting their needs. For our clients from Latin America, I provide the essential link between cultures and languages.  At the same time, I have enjoyed working on US-based litigation matters and drafting pleadings and memoranda related to those cases.”

Lidia represents clients in a variety of industries in international and domestic arbitration in the U.S. and Brazil.  She also handles complex U.S. litigation matters, including insurance and reinsurance.


Lidia has represented foreign and national companies before U.S. courts and international arbitral tribunals. She also advised owners and contractors managing claims and disputes in ongoing mid-and-large-scale infrastructure projects.  Lidia is a native Portuguese speaker.

Lídia represents clients in international and domestic commercial arbitrations under the ICC, SCC, UNCITRAL, LCIA, and AAA rules, and in litigation before U.S. courts. Her cases focus on matters of construction, infrastructure, oil and gas, insurance and reinsurance, Foreign Sovereign Immunities Act (FSIA), complex contract disputes, and matters at the intersection of common and civil law. Prior to joining Chaffetz Lindsey, Lidia practiced for five years at a mixed law and engineering boutique firm in Brazil, working side by side with civil engineers in complex construction matters. Lidia is a native Portuguese speaker.
