The Taipei Advocates Union was established during the period Taiwan was under Japanese occupation. In 1945, the Republic of China government assumed control of Taiwan, as well as the Taiwan High Court and the Taipei District Court, from the Japanese Governor-General's Office. In the same year, lawyers practicing in Taipei merged the Taipei Advocates Union and the Law Society of Taipei to form the Taipei Bar Association (TBA). On August 15, 1947, the TBA was officially established under the Lawyers Act.
