Chambers Review (HNW): Sean McWeeney QC, is a “well-established name” in the market. One peer says: “He is one of the best offshore lawyers across the board and certainly the go-to person for Bahamas work. He has handled some huge cases and the market unanimously sees him as the best private client lawyer in the Bahamas. He is very sophisticated, has great judgement and is very thoughtful and charismatic.” A market insider enthuses: “He is remarkable. He is hands-down still the guru. He is a champion of the industry and the island.”

Chambers Review (Global): Sean McWeeney QC remains a widely respected figure, and is particularly known for his skills in trusts and estates and private wealth matters. Industry sources praise his way of “very proficiently manoeuvring clients through bureaucratic systems.” One commentator added: “He’s in a class of his own.”
