Administrators of the estate of late tycoon Teddy Wang Teh-huei have launched legal action against his widow, Nina Wang Kung Yu-sum, over a property development firm formed in 1975. The administrators and two partners in the company have lodged a writ with the High Court requesting Mrs Wang - Asia's richest woman - account for $14 million the property firm has earned over the past 12 years. The plaintiffs accuse Mrs Wang of failing to share revenue from her Chinachem Agencies Limited, which was appointed to collect rental and other payments from the property firm, On Shiu Enterprises Limited. The plaintiffs are named as the administrators, Kam Ting Company Limited and Ching Wing Company Limited. Mrs Wang, Chinachem Agencies and Mrs Wang's father-in-law - Wang Din-shin - are named as the defendants. Kam Ting and Ching Wing have been controlled by Mrs Wang since her husband's disappearance in 1990, but the administrators appointed directors to the companies in 2001 and 2002. According to the writ, Kam Ting, Ching Wing, Mrs Wang, Teddy Wang, Mr Wang and legal adviser Donald Quintin Cheung were shareholders in On Shiu Enterprises Limited, which was set up to develop a high-rise property in Kwai Chung. Mr Cheung advised Teddy and Nina Wang to place the firm into liquidation for tax reasons and continue its business through a partnership, which was formed in May 1975. The directors of Kam Ting and Ching Wing, which owned more than 80 per cent of shares in the partnership, agreed income from the property development should be collected by Chinachem Agencies, which has been under the sole control of Mrs Wang since April 1992. 'To the best of the plaintiffs' knowledge, neither the said net rental income nor any part thereof has been distributed to the partners at any time,' the writ alleges. Despite repeated demands, Mrs Wang failed to attend partnership meetings called by Kam Ting and Ching Wing last year, the writ says. She had also failed to account for the property firm's profits received by Chinachem Agencies. On August 9 this year, Kam Ting and Ching Wing gave Mrs Wang notice of their intention to dissolve the property firm, the writ says. The plaintiffs are seeking an account from Chinachem detailing all payments received from the property firm.
