A high-profile Hong Kong court case surrounding a battle over the fortunes of late billionaire Nina Wang highlights the dangers surrounding such legal tussles and the need for tough estate planning, says Withers, the international law firm.

Earlier this week, the Hong Kong High Court found that Tony Chan, a former partner of Ms Wang, was not entitled to any of her fortune, stating that a will upon which he based his claims was forged. As a result, Ms Wang’s fortune will go to a charity that she founded, while the man is likely to be investigated by the Hong Kong police, Withers said in a briefing note.

Media reports said that Mr Chan had been arrested by police.

“While the Nina Wang case has hit the headlines because of the astronomical sums of money involved, the sad reality is that many vulnerable elderly individuals are subjected to pressure from unscrupulous persons aiming to get a slice of their estate. Such practices have increased around the world in recent years as property values have risen, causing an associated rise in the value of estates,” said Patrick Hamlin, counsel in the contentious trusts and succession group at the firm.

“This case highlights these issues and will make families aware that those close to vulnerable individuals could exert influence over them. It could serve as a catalyst for those who smell a rat to challenge wills,” Mr Hamlin said.

“The case also shows how bitter, complicated and expensive succession disputes can be – it is certain that each side will have spent millions in legal costs. Clear communication with family members and good, impartial advice can prevent such disputes arising in the first place,” he said.
