Linked Reviews
Corporate and M&A (asialaw)

Work highlights 

Advised K-nex Corporation on its $31 million acquisition by PTT Oil and Retail Business Public Company, representing one of Thailand's prominent laundry and dry-cleaning franchise startups in a corporate restructuring and subsequent sale. The transaction involved an entire business transfer structure to optimise tax efficiency, with comprehensive support including negotiations of key transaction documents, due diligence coordination and regulatory compliance. The deal marks a significant exit in Thailand's consumer services sector. 

Key clients 

Larch & Laurel Co, Sam Precision (Thailand), Zhi-Ler Holding (Thailand) Co 


Dispute resolution (asialaw)

Work highlights 

Represented Racha Resort and its director in defending against the Office of the National Anti-Corruption Commission's proceedings seeking revocation of land title deeds for The Racha luxury resort in Phuket. The Bt100 million ($2.8 million) case challenged the validity of property rights involving multiple parties including senior local authorities. The Court of First Instance dismissed all claims against the resort owner, safeguarding crucial property rights and establishing an important precedent for land title legitimacy cases in Thailand's hospitality sector, with appellate proceedings ongoing. 


Labour and employment (asialaw)

Work highlights 

Representing Thai Yamaha Motor in a Bt80 million ($2.2 million) labour dispute against former management over fraudulent activities in the golf car division. The case centres on battery supply irregularities and non-compete violations that caused significant damages to the company's operations. In March 2024, the Court of First Instance ruled in favour of Thai Yamaha Motor, ordering compensation of Bt51.6 million ($1.4 million). The matter is currently under appeal.
