His primary focus is on complex, corporate/commercial and banking & finance litigation. He advises regularly on domestic and multi-jurisdictional shareholder, joint venture and corporate disputes. His advice is highly sought after in cases involving financial institutions and allegations of mis-selling, misconduct, misrepresentation, deceit, fraud, and breach of duty. He has also advised clients on a range of regulatory investigations conducted by authorities in the UK and US, including the Financial Conduct Authority and the Securities and Exchange Commission, and has worked on various contentious restructurings and anti-trust/competition matters, representing clients in the Competition Appeal Tribunal, High Court and the Court of Appeal.

Alexander is referenced as a recognised practitioner for commercial and corporate litigation in the Chambers and Partners, 2020 directory.

Legal 500 notes that Alexander is “tremendously bright, has acute commercial judgement, and is a good choice for clients who want a personal service but with Magic Circle brainpower”. The directory also describes Alexander as “exceptional”, “outstanding”, “commercially focused”, “impressive”, “very hardworking and responsive” and having “a clear incisive mind” and an “acute tactical and strategic sense”. Alexander is particularly “noted for complex, high-value disputes involving financial institutions and hedge funds, including those under the ISDA Master Agreement” and is also noted for his “expertise in shareholder and joint venture disputes, and matters involving breaches of directors’ duties”.

Alexander Weinberg is first class. His business acumen and advice is excellent. He is very professional and quick in response. I would not hesitate to recommend him thoroughly.
