A law firm which last year pioneered an online legal service is being sued by a client who accuses it of breach of contract. In a High Court writ filed yesterday, estate agent Mak Sau-fong claims that Robert W. H. Wang & Co failed to offer proper legal advice when she agreed to mortgage her Taikoo Shing flat for $6 million to a friend, convicted fraudster Simon Chan Ying-ming. As security, Chan gave Ms Mak shares in Sharp Brave Holdings Ltd worth $5 million and deposited the share certificates with the law firm, the writ said. The agreement between the rogue businessman and Ms Mak was struck in February 1997. The former chairman of Billion International Holdings, Chan had an extra 23 months imposed on his six-month jail term in March 1999 by the Court of Appeal. Chan, who ran a bogus bank, had admitted soliciting and taking cash deposits from clients without authority. The court had heard $100 million owed to 364 clients is still missing. It was claimed Ms Mak was convinced to make the deal with Chan after solicitor Charles Yuen Chi-lai, of Robert W. H. Wang & Co, advised her to accept the proposal because Chan was a 'highly successful businessman'. 'Robert Wang provided an unqualified recommendation as to the merits of entering into the agreement and transactions without providing any advice or warning as to the associated risks, including, without prejudice to the generality, the risks identified,' the writ said. Ms Mak claims she suffered loss and damages, including the value of the shares.
