Jonathan Allcock

Call 2007


Jonathan is recommended for Commercial Chancery work by Chambers UK, which describes his advocacy as “excellent”.  He has substantial experience across a broad range of commercial and chancery litigation, with a particular emphasis on the following areas:

  • General commercial and contractual disputes;
  • Civil fraud, tracing and asset recovery;
  • Corporate insolvency and bankruptcy;
  • Company and partnership disputes;
  • Trust litigation;
  • Property law;
  • Landlord & Tenant (both commercial and residential); and
  • Professional liability.

Jonathan appears regularly in the High Court (particularly the Chancery Division and the Commercial Court) both as a sole advocate and as a junior, but has also appeared in the Court of Appeal and the Privy Council, as well as the County Courts and some specialist tribunals.  He also worked on a number of very high value cases in the Grand Court of the Cayman Islands while on secondment in the litigation and insolvency practice group of Appleby.

In addition to his trial experience, which includes appearing un-led in complex and lengthy High Court trials, Jonathan has advised and appeared on a wide range of interim applications, including applications for freezing and proprietary injunctions, committal orders, security for costs, orders for cross-examination, civil restraint orders and disclosure orders.

Before being called to the Bar, Jonathan read Modern Languages at Trinity College, Oxford, where he was a scholar and was awarded a distinction in his preliminary examinations and a first in his final examinations. He subsequently completed the Diploma in Law (CPE) at City University, gaining a distinction and winning the Maitland Advocacy Prize, and was classed as outstanding at Bar School. He was also a Harmsworth Scholar and Queen Mother Scholar of the Middle Temple.
