Andrew Ong has diversified experience as an Assistant Registrar in the Supreme Court for 3 years, an active litigation partner specialising in Shipping and Commercial Litigation for the next 16 years, and a 4 year stint as a Regional Chief Operating Officer covering five countries in the Business World.

Andrew started his legal career in 1989 in the Singapore Legal Service where he held the appointment of Deputy Registrar of the Subordinate Courts and Small Claims Tribunal referee. He was gazetted as a Magistrate in 1990 and held the position of Assistant Registrar, Supreme Court from 1990 to 1992.

Since moving into private practice in late 1992, he has practised extensively in the area of Admiralty and Shipping law and has won numerous accolades and recognition in the following international publications:

  • Chambers Global – The World’s Leading Lawyers (2001 to 2008). 
    where he is described as 'able and tenacious', ‘A sedulous worker’, 'whose good sense exudes from his every pore' and ‘focused, experienced and prominent’.
  • Asia Pacific Legal 500 (2001 to 2006).
  • Euromoney Guide to the World’s Leading Shipping & Maritime Lawyers (2004).
  • International Financial Law Review (2005).
  • Chambers Asia (2008).

After practising in another leading firm from 1992 to 1998, Andrew joined Rajah & Tann as a partner in 1998 in its Admiralty and Shipping Practice. He was instrumental in contributing to the growth of that practice in the Firm to become the leading practice in Singapore before moving on to join the Firm’s Commercial Litigation Practice.

Andrew practised extensively in the area of commercial litigation and was the lead partner of the Firm’s practice in Stockbroking and Securities related litigation involving recovery of contra losses, advising on Stock Market practices and other issues pertaining to the Singapore Exchange Securities Trading Limited and its member firms. Together with fellow partner David Yeow, Andrew advised the majority of all Stockbroking firms in Singapore.

In 2008, Andrew was approached to enter the business world. He left the Firm in May 2008 to take on the appointment of Regional Chief Operating Officer of the True Group, a Fitness & Yoga, Spa and Aesthetics group spanning 30 centers in Singapore, Malaysia, Thailand, Taiwan, India and China. He has gained valuable insight into the intricacies of the business world in the four years that he was in the True Group.

In 2012, he returned to the firm to become the full time Business Development Partner of the firm.  Currently, he spearheads Business Development and Client Relations not just for Singapore but for all 10 countries in the Rajah & Tann Asia Network.  He is also concurrently the partner in charge of Regional Operations for Rajah & Tann Asia.


In presiding over cases in the Subordinate and Supreme Courts in the early years of his career, Andrew acquired a diverse and unique perspective in civil litigation practice. He had the privilege of supervising many departments in the courts, hearing cases and handling files in relation to interlocutory and pre-trial applications, probate, divorce, bankruptcies and winding–up, enforcement and execution of Judgments, admiralty proceedings, assessment of damages, appeal processes, small claims tribunal hearings, taxation and review proceedings etc.

His experience in the admiralty and shipping practice was varied and extensive in both “wet” and “dry” contentious matters covering such areas as oil and marine pollution liability, oil contamination claims and other quality/quantity disputes, charterparties , bills of lading , cargo damage, shipbuilding and repairs disputes, tug and tow matters, and other multi-modal transport issues.

His commercial litigation practice covered all aspects of general and commercial litigation, en-bloc sales and property related disputes, contractual disputes, employment disputes, personal injury claims, common law actions including defamation, nuisance, negligence and other torts, partnerships and shareholders disputes.

Since 1993, he has also specialised in Stockbroking and Securities related litigation dealing with all aspects of the stockbroking industry and SGX related issues. He has extensive experience in acting for numerous stockbroking companies in litigation involving recovery of contra losses, unauthorised trading, trading limits, trust monies, compliance with SGX Bye-laws and Regulations, disputes under letters of appointment/agency agreements and other issues pertaining to Dealers and Remisiers in the stockbroking industry. He has acted as lead counsel in many landmark decisions on stockbroking matters pertaining to unauthorised trading, compliance with SGX Bye-Laws and Regulations, indemnities provided by Dealers and Remisiers under their Letter of Appointment / Agency Agreement for cash and margin accounts, agency of a Remisier and the liability of a client involving a nominee arrangement.
