Financial and Banking Disputes

Keidan Harrison are one of a limited number of specialist disputes law firms who can credibly take on the banks in substantial financial litigation.

This is because we are free from the conflicts of interest that preclude most leading litigation lawyers in the major national and international firms from taking on such work.

Our lawyers have acted on a wide range of financial and banking disputes, including those which arose out of the 2008 banking crisis and subsequently. Our expertise includes:

  • Disputes involving the recovery of debts and assets from banks or other lenders arising out of non-performing loans, including cases where there is a dispute over the value of assets that have been seized and disposed of in part satisfaction of liabilities to the lender.
  • Claims arising out of the restructuring of companies conducted pursuant to the terms of an intercreditor agreement.
  • Claims arising out of the enforcement of security, guarantee obligations, letters of credit, guarantees, performance bonds, collective facilities, derivatives and swaps transactions and other leveraged investments.
  • Claims for negligence, breach of statutory duty, mis-selling and benchmark fixing and manipulation against banks, financial institutions and financial advisers arising out of investments and the sale of regulated financial products.
  • Claims for dishonest assistance, breach of trust or arising from breach of the Quincecare duty.
  • Claims arising from mistaken payments procured by third-party frauds and in actions where the bank itself is the fraudulent party or failed to prevent the fraud.

Our Partners are recognised by the legal directories as leading lawyers in London in this practice area, having acted successfully in several landmark cases and maintaining a consistently substantial caseload in this field. Since the banking crisis of 2008, they have acted in numerous cases against almost all the major UK banks, as well as many other leading banks and investment banks worldwide.

Our clients are drawn from a broad range of sectors and demographics. Our Partners have acted for FTSE 250 entities, hedge funds, asset managers and private equity houses, as well for other individual borrowers and investors facing issues relating to banking and lending arrangements. Several of these cases have had an international angle and we have experience of working alongside disputes lawyers in other jurisdictions – most notably in the US – to provide a seamless service to clients where trans- jurisdictional disputes arise.
