Where Advocacy Meets Business

To achieve the best possible outcome for my clients, I love thinking through complex facts underlying a dispute in order to assemble the base case then collaborating with colleagues to anticipate and address all potential concerns.

Matilde has experience in international commercial arbitration and investment disputes. She has handled cases conducted under all major arbitration rules, including ICDR, ICC, UNCITRAL, ICSID and LCIA.  Her cases have involved disputes in the energy sector, construction, licensing and distribution agreements and banking and finance. Matilde has specific experience with damages modeling in the context of long-term contracts.


Prior to joining Chaffetz Lindsey in August 2019, Matilde was an associate at an international law firm, based in Paris, where her practice focused on complex commercial and investment arbitrations.
