Overview
Gunster advises ultra-high-net-worth individuals, multigenerational families, family offices, fiduciaries, and closely held business owners on complex cross-border tax, estate, and succession planning matters.
Our lawyers counsel clients whose families, assets, and businesses span multiple jurisdictions, including on pre-immigration and expatriation planning, international trust and estate structures, inbound U.S. investments, cross-border business transactions, and family-office governance. We coordinate U.S. legal and tax planning with foreign counsel, accountants, fiduciaries, and investment professionals to develop and deploy integrated strategies across jurisdictions.
What Sets Gunster Apart
We approach each engagement by examining the client’s global ownership structure as a whole, including trusts, entities, operating businesses, investments, family relationships, and relevant jurisdictions.
Working with advisors worldwide, Gunster devises and coordinates integrated global legal, wealth preservation, and tax strategies. We help families assemble and coordinate their global advisory teams, identifying and working alongside foreign counsel, accountants, fiduciaries, and investment professionals.
For many families, our role continues well beyond a particular transaction or planning project. We provide ongoing counsel as ownership, family circumstances, investment structures, and jurisdictions change over time. Knowing clients seek continuity, sophistication, and trusted oversight, our team is strategically composed of next-generation counsel equipped with exceptional depth and experience to foster decades of dedicated partnership.
