Strong across the bench in all things company and insolvency related‘, South Square has a foundation in insolvency related instructions but also real strength in shareholder litigation, as well as the recently popular area of schemes of arrangement. One of the highlights in that area was a scheme to compromise mis-selling claims against Provident Financial plc, one of the largest ever schemes of arrangement, with more than 428,000 creditors voting at the scheme meeting. Barry Isaacs KC led Adam Goodison and Ryan Perkins advising Provident, with Tom Smith KC acting for the FCA on the opposite side. Members of chambers have also been involved in some of the market-leading shareholder disputes, including Ma v Wong, where David Alexander KC led Perkins for the latter party.
