Nadia Chiesa specializes in commercial litigation and multi-jurisdictional disputes in Canada and the Caribbean.

Nadia is Chair of the Commercial Litigation Practice Group at WeirFoulds LLP. She is part of a team that focuses on multi-jurisdictional litigation involving complex corporate and commercial disputes in various jurisdictions including the Eastern Caribbean, Central America and the US.

Nadia has advised clients on a wide variety of matters, including multi-jurisdictional corporate disputes involving shareholder rights and director’s duties, the registration and enforcement of foreign judgments, commercial disputes, and offshore trusts and estates matters. She is also a member of WeirFoulds’ Anti-Corruption, Anti-Money Laundering and Regulatory Compliance group, and advises clients in these areas, including on extra-territorial freeze orders pursuant to anti-money laundering legislation, MLAT enforcement, treaty rights and obligations in these areas, and general due diligence relating to offshore banking and trusts requirements.
