Jonathan Muk
Jonathan Muk (麦政彦) is an advocate with significant experience in complex commercial litigation, arbitration, and asset recovery.
Jonathan was a recipient of the Lee Kong Chian Scholarship and read law at the Singapore Management University’s Yong Pung How School of Law. He graduated in 2013 with a double degree in Law and Business Management with a major in Finance (Summa cum Laude or with highest honours). He served as a Justices’ Law Clerk with the Supreme Court of Singapore before getting called to the Singapore Bar in 2016.
Jonathan has acted in some of Singapore’s most significant fraud and asset recovery matters. He was an integral part of the team representing a state-owned company in the consolidated trial of 5 interpleaders involving oil cargoes valued at more than USD 300 million. The trial was one of the largest and most complex trials in Singapore’s history running for 6 years and being heard over 74 days in the High Court. He was also an integral part of the team acting for the liquidators of BVI companies linked to the 1MDB scandal. The actions launched included a USD 2.7 billion claim against a major international bank. He also acted for a victim of a Ponzi scheme to secure judgment of over SGD 10 million against the victim’s uplines for fraudulent misrepresentation.
As lead counsel, Jonathan has led trials in the superior courts in matters involving mental capacity, minority oppression, and fraud.
Jonathan also has a strong track record in obtaining search orders against parties who have misappropriated confidential information and effecting ship arrests against vessels – remedies which require precision, speed, and a court’s trust in counsel’s candour.
Clients have commended Jonathan for being “energetic, passionate, and creative” (Legal 500 Asia Pacific, 2025), “very attentive to the case and very prompt in providing detailed feedback, as well as clear and strategic advice on the way forward” (Asialaw, 2022), and doing “good-quality research” (Legal 500, 2024).
Jonathan firmly believes in mediation as a way to resolve disputes. He is an empanelled mediator with the Borneo International Centre for Arbitration and Mediation, the Singapore International Mediation Centre, the Singapore Mediation Centre, and under the Law Society Mediation Scheme. He has been appointed a mediator for multiple cases. He is also a neutral evaluator with the Financial Industry Disputes Resolution Centre. In these capacities, Jonathan has been commended for managing expectations and emotions well and has received positive feedback for his “good control of the proceedings”, ability to build “good rapport with the parties”, and “helping explore and develop options” for the parties to resolve their dispute amicably.
Finally, Jonathan is passionate about improving the legal profession. He is presently appointed as Co-Vice Chairperson of the Law Society of Singapore’s Alternative Dispute Resolution Committee as well as a member of the CPD Committee, Advocacy Committee, and the Mentorship Scheme Working Group. He also presently teaches as an adjunct faculty at the Singapore Management University’s Yong Pung How School of Law.
