HONG KONG, (Reuters) – The late Hong Kong  billionaire Nina Wang wanted to have a child with the feng shui  enthusiast laying claim to her inheritance, his lawyer said yesterday in a bitter legal battle with Wang’s family for her  billions.

Wang, who died in April 2007 aged 69, was one of Asia’s  wealthiest women whose business empire, including the Chinachem  Group, the city’s largest private property developer, has been  estimated to be worth at least $4.2 billion.

The existence of two conflicting wills, however, has pitted  Tony Chan, her former lover, against her family represented by  the Chinachem Charitable Foundation in a long-awaited probate  battle that began on Monday.

“(Tony Chan) was the object of her love for the last 15  years of her life,” said Chan’s lawyer, Ian Mill, in his  opening submission on the second day of the 40-day hearing.

“She wanted to have a child with (Chan)“ Mill added.

The Foundation’s lawyers said earlier there was “very  strong evidence” that Wang’s signature on the 2006 will as she  lay dying of ovarian cancer was a forgery. Instead it lays  claim to a 2002 will in which Wang left most of her wealth to  charitable causes.
