Corporate, Investment and Insolvency Disputes

Specialist representation in complex corporate and investment disputes

We represent corporates, investors, directors, shareholders, financial institutions, high-net-worth individuals and family offices in disputes going to the heart of corporate control and investment value. We have deep experience in post-M&A disputes, shareholder litigation, partnership breakdowns, fund management disputes and corporate insolvencies. We advise on disputes involving crypto assets, fund collapses, valuations and distressed exits. 

Our substantial team of specialist litigators is regularly instructed on high-stakes cases that involve significant commercial and reputational risk. We work with public and private companies, funds, investors and asset managers, as well as liquidators, administrators and receivers, and directors, partners and corporate officers. 

We regularly appear in international litigation before the English courts, and in international commercial arbitrations. We frequently act alongside leading firms in the US and other jurisdictions to deliver a seamless approach to complex international disputes involving multiple parallel proceedings. 

Our approach combines our strength in litigation with our deep understanding of the drivers affecting corporates and how investments are structured, financed and managed. We are naturally collaborative, working closely with our colleagues across the firm including in Corporate, Private Capital, Financial Regulation and Tax, to provide seamless and fully-integrated advice – whether in or out of court. 

We regularly advise on:

  • post-M&A disputes, including warranty and indemnity claims;
  • shareholder and boardroom disputes, including unfair prejudice petitions and derivative claims;
  • issues arising in joint ventures, LLPs and partnerships;
  • breach of duty and misfeasance claims against directors and officers;
  • corporate fraud, misrepresentation and rescission;
  • insolvency litigation, including wrongful trading, preferences and transactions at undervalue;
  • enforcement of security and intercreditor disputes;
  • fund-related claims, including disputes over LP and GP obligations;
