Adrian Tan

Adrian Tan Gim Hai (4 February 1966 – 8 July 2023) was a Singaporean lawyer and author.

Known for writing the Teenage Textbook series of books in the 1980s, he was the 27th president of the Law Society of Singapore and a partner at TSMP Law Corporation.

Tan was born in Singapore to an ethnic Chinese family of Hainanese descent.

His parents were both teachers, and he grew up in a Housing Development Board (HDB) flat.

As a child, Tan attended the Anglo-Chinese School and Hwa Chong Junior College.

Tan was later conscripted into the army as a writer for Pioneer, the MINDEF magazine.

After his A-levels, he was offered a teaching scholarship to study English at the University of East Anglia.

He turned down the scholarship to study law at the National University of Singapore (NUS).

While in university, Tan represented NUS as a debater in international competitions and televised debates in Singapore.

While an undergraduate law student at NUS, Tan wrote the novels The Teenage Textbook (1988) and The Teenage Workbook (1989), which became bestsellers that sold over 50,000 copies.

After graduating from NUS with a Bachelor of Laws degree, Tan began his legal career in 1991 at Drew and Napier, a large Singaporean firm.

He initially practiced conveyancing law, but switched over to litigation thereafter, where he worked under Davinder Singh.

The Teenage Textbook was also made into a stage play by The Necessary Stage in 1997; a film in 1998, which topped the box office in Singapore for four weeks; a 2017 musical titled The Teenage Textbook Musical; and a 2021 TV series on Channel 5.

In 1999, Tan left Drew for a two-year stint as general counsel of a technology firm, following which he returned to Drew.

He later completed a second, joint-honours degree in computer science and psychology from the Open University in 2004, while working as a lawyer.

Eventually, after 22 years at Drew, Tan left to work for Stamford Law (now Morgan Lewis Stamford) in 2013.

From 2013 to 2021, Tan was a member of the Law Society Council, serving as treasurer in 2016 and vice president in 2017.

In 2022, he was appointed president.

As president of the law society, he was known for his public outreach on legal issues, such as the HDB's ban on cats, the 2022 bar exam cheating scandal, and Richard Branson's comments on the death penalty in Singapore.

Tan gave his only Opening of the Legal Year speech as Law Society president in 2023, where he addressed attrition rates in the legal profession.

Tan was married without any children.

He was diagnosed with cancer in March 2022, and died on 8 July 2023, at age 57.

At a memorial service celebrating his life, Tan was said to be someone who "had very little ego", was a champion of the legal profession and who "cared for the less fortunate."

In 2015, The Teenage Textbook was listed by The Business Times as one of the top 10 English Singapore books from 1965 to 2015.

Tan also was a consultant for the Channel 5 television legal drama The Pupil.

Tan was invited to a National Library Board festival but later boycotted it over the board's decision to withdraw from its libraries children's books that depicted same-sex families.

In 2018, Tan resigned from Stamford to work at TSMP Law.

Tan practiced litigation, and specialised in intellectual property, information technology, real estate, and shareholder oppression disputes.

He was also the honorary counsel of the Singapore Association of the Visually Handicapped, where he advocated for voting rights for the blind.

He was also a member of the boards of the Law Society Pro Bono Services, Maxwell Chambers, and Arts House Limited, and was a member of the Speak Good English Movement committee.
