Direct peers

• Tilleke & Gibbins: One of the largest and longest-established independent law firms in Thailand, offering comparable full-service coverage including corporate, M&A, IP, dispute resolution, and regulatory practices. Headcount and practice breadth closely mirror Rajah & Tann Thailand, making it the most direct local competitor for both Thai and international clients.
• Siam Premier International Law Office: A well-established Thai law firm providing full-service legal coverage in corporate, M&A, banking, litigation, and regulatory matters. Comparable in positioning as a top-tier domestic firm serving both Thai corporates and inbound international clients.
• Weerawong, Chinnavat & Peangpanor: A leading Thai independent law firm with comparable full-service corporate, M&A, banking, dispute resolution, and regulatory practices. Frequently cited as one of the top domestic firms in Thailand and a direct competitor for high-end Thai-law mandates.

Broad incumbents

• Linklaters (Bangkok): Global Magic Circle firm with a Bangkok presence covering corporate, M&A, capital markets, and projects. Competes for high-end cross-border mandates with Thai-law elements, drawing on a much larger global platform.
• Clifford Chance (Bangkok): Global Magic Circle firm with a Bangkok office covering corporate, finance, capital markets, and dispute resolution work. Competes for premium cross-border mandates that include Thai-law components, particularly in banking & finance and project development.
• White & Case (Bangkok): Global firm with a Bangkok office active in M&A, project finance, capital markets, and dispute resolution. Competes for premium cross-border mandates in Southeast Asia involving Thai-law issues.
• DLA Piper (Bangkok): Global full-service law firm with a Bangkok office covering corporate, finance, technology, and regulatory work. Competes with R&T Thailand for mid-to-large corporate mandates, particularly in TMT and cross-border transactions.
• Allen & Overy / A&O Shearman (Bangkok): Global firm (post A&O / Shearman & Sterling merger) with a Bangkok office focused on banking & finance, projects, energy, and corporate transactions. Direct competitor in the Banking & Finance and project development practice areas where R&T Thailand is active.
• Baker McKenzie (Bangkok): Global Magic Circle firm with a long-standing Bangkok office offering corporate, M&A, banking, dispute resolution, and TMT practices. Competes with R&T Thailand for cross-border mandates involving Thai law, leveraging substantially larger global resources.

Others
