Singaporean litigator Adrian Tan has left Drew & Napier for Stamford Law Corp.

Tan will join the firm as a director, a partner-equivalent position. He had been with Drew & Napier for 21 years, specializing in defamation, intellectual property, and corporate disputes.

Tan has been involved in a number of high-profile cases. Earlier this year, he represented a father and son suing Credit Suisse for allowing the son, who was under 21, to trade on the family’s account and ultimately lose $726,000. In 2005, he successfully represented Singapore Press Holdings, owner of The Straits Times, against a defamation suit brought by the National Kidney Foundation, which the newspaper had said was squandering donations on executive perks.

To many Singaporeans, Tan is perhaps better-known for two best-selling novels he wrote when he was a university student in the late 1980s. “The Teenage Textbook” and “The Teenage Workbook” followed the lives of students studying at a fictitious junior college in the city-state.

Stamford Law Corp. now has 81 lawyers, including 20 directors.
