Basil Zirinis
Spear’s Review
‘If an HNW wants to invest or do business in the US, Basil is the go-to,’ one peer enthuses when asked to recommend an international private client lawyer for this index.
When Spear’s contacts the New York- and London-based Zirinis, he’s delighted to speak: ‘You have the most sophisticated English law firms, I think – I work with all of them.’
Having been a partner at Sullivan & Cromwell since 1994 – he currently leads its international private client practice – Zirinis has extensive experience in trust and estate litigation. Highlights include US-Bahamas litigation representing Chicago’s Pritzker family, the America’s Cup trust litigation in New York, and ‘a multi-billion-dollar’ trust case in Europe and the Caribbean. He is a regular attendant at major legal conferences in Europe, the Caribbean and the US.
