The attorney-general of Singapore is the public prosecutor of the Republic of Singapore and legal adviser to the Government of Singapore. The attorney-general is the head of the Attorney-General's Chambers (AGC), whose staff carries out the functions of the attorney-general. The attorney-general is appointed by the president, on the advice of the prime minister, under Article 35 of the Constitution of Singapore. Unlike some countries that follow the Westminster parliamentary model, the attorney-general is not a Member of Parliament.
The Office of Attorney-General was established in 1867, when the British Crown appointed the attorney-general of the Straits Settlements, based in Singapore, to serve as legal adviser to the new Crown colony's government.
The attorney-general of Singapore has two distinct roles: legal adviser to the Singapore Government and public prosecutor, assisted by legal officers in the four divisions of the Attorney-General's Chambers (AGC).
The attorney-general's role as the Government's legal adviser is performed by the AGC's Civil Division. The functions of the attorney-general include advising ministries and organs of state on legal matters; drafting and vetting contracts and legal documents; and representing the Government in international initiatives and litigation matters, among others.
The International Affairs Division advises Government agencies on international-law issues, represents Singapore in bilateral and multilateral negotiations, and negotiates and drafts multilateral and bilateral legal instruments, among other roles.
The Legislation Division comprises four groups. The Law Drafting Group drafts legislation and advises Government agencies on development of legislation. The Legislative Editorial and Revision Group undertakes law revision. The Law Publication Group maintains Singapore Statutes Online, among other duties. The Business Services and Governance Group provides administrative support to the other groups.
The attorney-general's role as the public prosecutor is performed by the AGC's Crime Division. Prosecutorial discretion grants the attorney-general the power to institute, conduct or discontinue any prosecution at the attorney-general's discretion.
Between the grant of the Second Charter of Justice in 1826 and the formation of the Crown colony of the Straits Settlements in 1867, the function of legal adviser to the government in Singapore was vested in various offices. From 1826 to 1855, it was the Recorder of the Prince of Wales Island, Malacca and Singapore; from 1855 to 1864, the Recorder of Singapore; and from 1864 to 1867, the Crown Counsel, Singapore.
The office of Attorney-General was created on 1 April 1867, when Sir Thomas Braddell was appointed as the first attorney-general of the Straits Settlements. He was based in Singapore while his solicitor-general, Daniel Logan, was based in Penang.
Following the fall of Singapore on 15 February 1942, Japanese troops arrested the attorney-general, Charles Gough Howell, , who died in Japanese captivity. Concurrently, the civilian courts ceased to function.
Subsequently, the Japanese military administration established the office of Kensatsu-kan, or Attorney-General and Public Prosecutor, presumably on 27 May 1942 when the civilian courts were re-opened by proclamation.
Following the formal surrender of Japanese forces in Southeast Asia on 12 September 1945, the responsibility of rendering legal advice to the British Military Administration of Malaya lay with its Chief Legal Officer.
When Singapore became a Crown colony on 1 April 1946, Sir Edward John Davies, was appointed as the first attorney-general of the Colony of Singapore.
After the State of Singapore gained full internal self-governance in 1959, Ahmad Mohamed Ibrahim was appointed State Advocate-General, becoming Singapore's first non-British legal adviser to the government.
Following the Republic of Singapore's independence on 9 August 1965, Ahmad Mohamed Ibrahim became the country's first attorney-general.
The appointment of Lucien Wong, , as the ninth attorney-general, was debated in Parliament. He was aged 63 at the time of his appointment. Article 35(4) of the Constitution provides that the Attorney-General shall vacate office upon attaining the age of 60, and his predecessor had retired upon reaching that age. Wong was subsequently reappointed for a three-year term from 14 January 2026 to 13 January 2029.
In 2026, during the Ministry of LawâÂÂs Committee of Supply debate, Workersâ Party MP Sylvia Lim described the constitutional process for appointing the Attorney-General as âÂÂthinâ and called for greater transparency about how candidates are selected for the role. Law Minister Edwin Tong rebutted those claims, stating that the appointment process is neither thin nor perfunctory and involves consultation with the Chief Justice, the chairman of the Public Service Commission, and the Council of Presidential Advisers before the Prime Minister advises the President, and arguing that making such deliberations public could politicise the office.
Prior to his appointment, Wong had been the personal lawyer of Prime Minister Lee Hsien Loong; in that capacity, he advised Lee on issues relating to the will of his father Lee Kuan Yew.
In September 2020, the AGC conducted a prosecutorial review for a wrongful conviction case of a domestic worker accused of a crime.
On 11 October 2024, the Court of Appeal ruled that the Singapore Prison Service and AGC had acted unlawfully by disclosing and requesting prisonersâ letters.
