These arise from actions heard in the Companies Court of the High Court of Justice under the Companies (Winding Up) Act 1890 and subsequent legislation. The files include copies of summonses, affidavits of various kinds, court orders, petitions, judges' notes, schemes of arrangement for companies, papers concerning the appointment and retirement of liquidators and receivers, certificates of taxation, etc. From 1972 the proceedings also include debenture actions.
