The call

Rajah & Tann sits behind a legal wall that keeps foreign firms and AI systems out of its core Singapore practice, with regulation rather than technology or size setting the terms of competition.

Rajah & Tann is the leading law firm in Singapore, meaning it handles complex legal cases and contracts for businesses and the government. It is hard to replace because Singapore law says only certain firms can practice local law in the courtroom and for official work, and foreign firms like Latham & Watkins are blocked from that work by rule. AI tools like Luminance can speed up reading contracts, but they cannot sign legal papers, go to court, or take responsibility if something goes wrong the way a real lawyer can. The biggest threat would be if Singapore's government changes the rules to let more foreign law firms in or to allow AI to take on more legal responsibility, which a government committee is reviewing in October 2025.

Why
01
AI pressure: Harvey, Luminance and similar generative-AI legal tools. AI speeds up document review and drafting inside the firm but cannot give licensed advice or appear in court, so it feeds the work rather than eating it. Could AI do the core job? Unlikely.
02
Bigger players: Qualifying Foreign Law Practices: Latham & Watkins, Clifford Chance, Linklaters, White & Case and other licensed foreign firms in Singapore. Nine foreign firms already compete for cross-border finance and M&A work in Singapore, but Singapore law bars them from domestic litigation and conveyancing. Could a giant copy it? No, they are blocked.
03
What protects it. Singapore law reserves domestic litigation, conveyancing and other core practice areas exclusively to Singapore-qualified lawyers, keeping foreign firms and AI tools out of that work.
What would change this call
Singapore Ministry of Law implements its Oct 2025 review on QFLP licensing thresholds. Would show whether foreign firms like Latham & Watkins or Clifford Chance gain access to reserved-practice work.
Rajah & Tann's associate-to-partner ratio or equity-partner count shifts materially over the next year. Would show whether AI tools are compressing leverage economics inside the firm.
R&T's Shenzhen or Southeast Asia offices report a partner departure or client loss to a QFLP rival. Would show early erosion of its regional leadership position.

Questions people ask
Is Rajah & Tann profitable?
As a private partnership, Rajah & Tann does not disclose profit figures. It ranked number one in the Straits Times/Statista 100 Best Law Firms survey published October 30, 2025, appearing in 19 of 22 practice areas, signaling strong commercial standing even without public financials.
Could AI replace Rajah & Tann?
Unlikely soon. Rajah & Tann has used Luminance AI for M&A due diligence since October 2017 and rolled out Microsoft Copilot firm-wide in 2025-2026, but Singapore law reserves domestic practice areas like litigation and conveyancing for licensed lawyers, blocking unsupervised AI advice.
Who is Rajah & Tann's biggest competitor?
Allen & Gledhill ranked number two behind Rajah & Tann's number one spot in the Straits Times/Statista 100 Best Law Firms survey published October 30, 2025. Nine Qualifying Foreign Law Practices, including Latham & Watkins and Clifford Chance, also compete for offshore work.
Who owns Rajah & Tann?
Rajah & Tann Singapore LLP is a private limited liability partnership owned by its partners, not a public company. Ng Kim Beng became Managing Partner in February 2025, and Lee Eng Beng serves as Senior Partner and Chairperson of the Rajah & Tann Asia network.
Can foreign law firms like Latham & Watkins take over Rajah & Tann's business in Singapore?
No, by law. Nine Qualifying Foreign Law Practices, including Latham & Watkins, Clifford Chance, and Linklaters, are barred under the Legal Profession Act from reserved Singapore domestic practice areas, confining them to offshore work worth over S$2 billion between 2021 and 2024, per Singapore's Ministry of Law, October 16, 2025.
Does Rajah & Tann use AI in its legal work?
Yes. Rajah & Tann adopted Luminance AI for M&A due diligence in October 2017, an early legaltech move, and more recently deployed Microsoft Copilot for Microsoft 365 firm-wide via partner Crayon in 2025-2026 to manage growing document and case loads.
