Shahrizat was born on 15 August 1953 in Penang. She was an active student in academics and also curricular activities. She attended Northam Road Girls' School and Madrasah Tarbiah Islamiah during her primary years, and pursued her secondary education at St. George's Girls' School. She then continued her school education in the prestigious Kolej Tunku Kurshiah in Seremban, Negeri Sembilan. She attended University Malaya Law School graduated with distinction in 1976. She then served as a magistrate for three years. Shahrizat was later appointed as the Assistant Treasury Solicitor. She leaves the public service sector in 1980 to become a partner in a law firm. Shahrizat was with Soo Thein Ming & Shahrizat for 16 years before she started her own legal firm, Tetuan Shahrizat & Tan, on 1 July 1983.
Shahrizat was the Member of Parliament for the Lembah Pantai constituency in Kuala Lumpur from 1995 to 2008. Housing squatters in Lembah Pantai under her leadership has been Barisan Nasional’s trump card. To date, some 90% of squatters in Lembah Pantai have been resettled and allowed to purchase their homes, according to Shahrizat. When Shahrizat first became the area’s MP in 1995, the problem of the day was squatters as well as other concerns, such as floods, fire, garbage collection, street lamps, and children’s scholarships. Nevertheless, some have disputed her contribution to the development seen in the constituency, with most development being private sector driven initiatives, or projects under the Kuala Lumpur City Hall, which is unrelated to her position as an MP. During the 1999 general election, Shahrizat narrowly defeated Zainur Zakaria. The counting of votes was fraught with controversy, and Shahrizat won after a recount was conducted. In an upset during the 2008 general election, she lost her seat to a 27-year-old newcomer, Nurul Izzah Anwar, daughter of Parti Keadilan Rakyatde facto leader, Anwar Ibrahim.
Post 2008 general elections
Prime Minister Abdullah Ahmad Badawi appointed Shahrizat as Special Adviser to the Prime Minister for Women and Social Development Affairs on March 18, 2008, recognising that this wing was not represented in his cabinet. It was said she would be working closely with the ministry she had once served. The special adviser position carries with it ministerial status whereby she gets access to information and is provided with an office and secretaries like a full Cabinet minister. However, she cannot attend Cabinet meetings. Upon Shahrizat's victory as Wanita UMNO Chairlady on March 26, 2009, and Najib Tun Razak becoming Prime Minister, she was reappointed as Minister of Women, Family and Community Development on April 10, 2009. To qualify to be appointed as a minister, she was sworn in as a Senator in the Dewan Negara the day before.
In late 2011, the National Feedlot Corporation cattle-farming project in Gemas, Negeri Sembilan, became an issue of public interest. Shahrizat's husband, National Feedlot Corporation Sdn Bhd executive chairman Datuk Seri Dr Mohamad Salleh Ismail, was charged with two criminal breach of trust charges, allegedly for misusing a loan meant for the development of the project. However, he was found to be innocent, and the Attorney-General’s Chambers withdrew charges against him due to lack of evidence. The Malaysian Anti-Corruption Commission cleared Shahrizat of any wrongdoing in the NFC issue. MACC Chairman Tan Sri Dr Hadenan Abdul Jalil had said that the panel made the decision after studying investigation papers and reports from the Attorney General's Chambers, and closed the case against the former Women, Family and Community Development minister and cleared her name.
