M&A, JV and Shareholder litigation

Allen & Overy has an active practice to handle litigation resulting from corporate transactions and related shareholder disputes.

Our experts advise clients on potential and actual claims arising from both public and private M&A and joint ventures, supporting sellers and purchasers (both public and private) across a variety of sectors on issues including purchase price adjustments, deferred consideration, warranty claims and other breaches of agreement.

Litigators in A&O’s Asian, European, and North American offices regularly handle corporate disputes, working closely with our market leading corporate teams to ensure we build on the insights gained from being the most active transactional firm in the world.

We use the full range of dispute resolution methods (litigation, arbitration, expert determination, mediation and negotiation) and frequently work with accountants and other experts on the quantification of loss. 

Our experience includes advising:

  • A global engineering and construction company in a joint venture dispute with one of the largest international concession and construction groups relating to the construction of a hospital in Doha.
  • A global private equity firm, defending a EUR350 million claim over the amount of additional consideration payable following the acquisition and subsequent disposal of a major brewing business.
  • An investment bank in English High Court proceedings against two professional services firms, claiming damages for professional negligence and/or a contribution under the Civil Liability (Contribution) Act 1978 in connection with the valuation of an M&A transaction.
