Corporate and M&A (asialaw)
Work highlights

Acting as counsel to K-NEX Corporation, one of Thailand's most prominent laundry and dry-cleaning franchise start-ups, on its $31 million acquisition by PTT Oil and Retail Business, a publicly listed company on the Stock Exchange of Thailand. The firm advised on the full transaction, including the pre-acquisition restructuring of K-NEX's corporate structure and the negotiation of key transaction documents with PTTOR. The deal represents one of the most notable exits for a Thai consumer services start-up, reflecting the growing appetite of major Thai conglomerates for acquiring high-performing, tech-enabled businesses in the sector.
Dispute resolution (asialaw)
Work highlights

Successfully defending UOB KayHian Securities (Thailand) and its directors against a criminal complaint brought by a customer under the Securities and Exchange Act, arising from the conduct of a marketing staff member who had traded securities in the customer's account without authorisation over a one-year period, with total trading volume of THB 830 million. The case attracted public attention given the scale of the alleged misconduct and the involvement of foreign directors of a prominent international securities firm, and the firm secured a successful outcome for all defendants.
Labour and employment (asialaw)
Work highlights

Advising the owners of the MV Mayuree Naree on the benefits and compensation owed to the vessel's crew under Thai maritime labour law, following a devastating attack in the Strait of Hormuz on 11 March 2026 in which the vessel was struck by two projectiles, causing a fire and forcing the crew to abandon ship. Twenty of the 23 Thai crew members survived and were rescued by the Royal Navy of Oman, while three crew members — believed to have been trapped in the engine room — were later confirmed dead. The firm advised on the full scope of compensation entitlements, covering both the surviving crew and the families of those lost, in a matter that arose from one of the most serious maritime security incidents in the region in recent years.
