Definition

Offshore & International Structuring Law Firms are legal practices specializing in the laws of offshore or international financial jurisdictions and their use in private wealth, investment funds, finance, corporate and fiduciary structures.

Overview

The term offshore describes jurisdiction, not legality or secrecy. Structures remain subject to tax, beneficial-ownership, sanctions, anti-money-laundering, substance and reporting rules. Onshore and offshore counsel must coordinate because a valid entity under its governing law may produce different consequences where owners, managers, assets or beneficiaries reside.
