Jonathan MUK (麦政彦) is an Associate Director of the Firm. He is a Singapore-qualified lawyer with a broad-based litigation, arbitration, and mediation practice, specialising in asset recovery on commercial cases involving fraud across sectors such as private wealth, oil and gas, shipping and commodities, and technology. As a significant number of Jonathan’s cases are international in nature, Jonathan has experience working with senior local and international practitioners from Australia, New Zealand, the People’s Republic of China, Hong Kong, Japan, Malaysia, the United States of America, the United Kingdom, the British Virgin Islands (BVI), and the Cayman Islands on both contentious and non-contentious matters.
Professional experience
As a testament to Jonathan’s speciality in cases involving fraud, Jonathan is an integral part of the team representing a major Chinese state-owned oil major in multiple interpleader proceedings to assert ownership and possession over oil cargoes worth over USD 250 million. The trial of the interpleaders was one of the largest and most complex trials ever conducted in Singapore and took place over a period of 4 months before the Singapore High Court. He is also a key member of the team representing the liquidators of BVI-incorporated entities in asset recovery claims arising out of the 1MDB scandal. One of these actions involves claiming against a major international bank for USD 2.7 billion. To round off, Jonathan was part of the team which successfully sued the uplines of a victim of a Ponzi scheme for fraudulent misrepresentation. Judgment was entered against the uplines for over SGD 10 million.
In terms of lead counsel work, Jonathan has acted as lead counsel at trial for (a) 2 individuals in the Family Justice Courts in proceedings related to mental capacity issues; and (b) a prominent nephrologist in the High Court in proceedings related to minority oppression, breach of contract, and misrepresentation. In both cases, allegations of fraud were made against Jonathan’s clients.
On top of his ability to represent clients in the most complex asset recovery disputes involving fraud, Jonathan has the rare distinction of having successfully represented multiple clients in applying for and obtaining Anton Pillar orders (also known as search orders) against wrongdoers who had misappropriated confidential information from their employers.
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).
Mediator experience
Jonathan firmly believes in mediation as a way to resolve disputes. He is an empanelled mediator with the Singapore International Mediation Centre, the Singapore Mediation Centre, and under the Law Society Mediation Scheme and has been appointed a mediator on 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.
Education & Languages
Jonathan was a recipient of the prestigious Lee Kong Chian Scholarship and graduated from the Singapore Management University Yong Pung How School of Law in 2013 with a Bachelor of Laws (Summa cum Laude or with highest honours) and a Bachelor of Business Management (Finance) (Summa cum Laude) through a double degree programme. He was called to the Singapore Bar in 2016 after serving as a Deputy Public Prosecutor with the Attorney General’s Chambers and as a Justices Law Clerk with the Supreme Court of Singapore, serving judges of the High Court and Court of Appeal. He is fluent in spoken and written English and Chinese and conversant in Cantonese and Bahasa Melayu.
Jonathan is passionate about improving the legal profession. He has been appointed as co-Vice Chairperson of the Law Society of Singapore’s Alternative Dispute Resolution Committee and is a member of the Advocacy Committee and the Mentorship Scheme Working Group. He has also served as an adjunct faculty and as a member of the Practice Advisory Committee at the Singapore Management University’s Yong Pung How School of Law.
