our expertise
Our Story

TSMP started as a humble seven lawyer team in 1998, founded by Dr. Thio Su Mien and Ms. Tan Bee Lian, both iconic law figures who honed their craft at Singapore’s largest firms. Today, we’re more than 60 lawyers-strong, with a preeminent reputation locally, as well as an enviable international clientele.

Our vision

We believe that the law is a calling, one that mandates us to go beyond the call of duty in serving the community.


Whether it’s on a sensitive transaction or in a complex courtroom battle, we’re the bannermen you want. You can count on the undivided attention of a team that prizes relationships over profits, and is dedicated to your cause, fighting hard yet fair.

Our Beliefs

every client - our only client

Don’t expect us to provide one-size-fits-all solutions. We approach every client with a clean slate, investing time in understanding their business problems and needs before creating customised solutions.

global briefing

Our in-depth knowledge of how Asia thinks and works has, time and again, proven invaluable in getting the deal done. We’re not bound by geography, however, frequently engaging on multi-jurisdictional transactions as well as with international counsel, and delivering on 24-hour turnaround demands.

excellence with integrity

The law is a noble profession. It demands uncompromising standards of excellence without sacrificing the principles of integrity. This underpins everything we do.

justice for all

We believe in fair play, and strive for truth and justice with neither fear, nor favour.

law is a calling

We have a duty to use its power for good – by helping to build the community of tomorrow, addressing injustice and speaking up for the defenceless.
