Wealth structuring, private client, formation of offshore investment funds, international taxation, M&A, joint ventures, private equity transactions, and wealthtech.

Martín Litwak is a lawyer specialising in wealth structuring and preservation, offshore investment fund formation, international taxation, and wealthtech, with more than 25 years of experience.

Founder of UNTITLED SLC, a boutique firm which evolved into the first Legal Family Office in the Americas, Litwak and his team regularly advise high-net-worth families, elite athletes and artists, entrepreneurs, corporations, and financial institutions across the Americas, the US, and Spain.

Martin is a renowned speaker, author, professor, and media contributor globally recognised for his expertise in high-net-worth client advisory.

During his extensive professional career, Martín has won numerous awards and has been included in multiple rankings of lawyers in his areas of expertise.

The Global Elite Directory 2025 selected him for the fifth consecutive year as one of the world’s most respected UHNW client legal advisors.

In 2025 he was qualified by the State of Florida as Foreign Legal Consultant.

At last, in 2025, Martín did what he has always done: listened. Observing that clients were seeking deeper specialization, he responded with UNTITLED Collection®, a group of firms in consulting, fiduciary services, and wealth protection, built to serve Latin American families across different profiles and planning objectives under one shared philosophy: strategic, independent, and conflict-free advisory. Three firms, one vision. UNTITLED SLC for bespoke international tax planning and wealth structuring. UNTITLED Sherpa® for families with sophisticated structures who need ongoing, coordinated advisory. EVOLVE for professional athletes and artists seeking financial stability beyond their active careers.

Currently, Martin is part of ALM’s Private Client Global Elite.

Martin has published three books: ‘What the wealthiest do to protect their assets’, ‘Tax havens and Tax Hells’, and ‘Wealth planning for celebrities’. He regularly writes articles for news outlets such as La Nación (Argentina), Forbes, and Funds Society, among others. A complete list of his publications can be found on his website, martinlitwak.com.
