Tony Chan lost his claim to Nina Wang’s fortune on Tuesday, after a court ruled the will was a fake.
A 2002 will was deemed to be valid, which left the estate to a charitable trust run by Mrs Wang’s family.
Mr Chan has not been charged but has been ordered to report back to police in March.
In 2007 Reuters reported that Wang was the sole beneficiary of Hong Kong tycoon Nina Wang’s multi-billion-dollar fortune. Wang’s lawyer described him as a low-key businessman and feng shui enthusiast. He played down the likelihood of a court battle with her family.
Speculation had been rife for weeks over the identity of the beneficiary of Ms. Wang’s estate, finally revealed on Friday to be Chan Chun-chuen by lawyer Jonathan Midgley.
In explaining why Ms. Wang — Asia’s richest woman with a net worth estimated at $4.2-billion (U.S.) — left everything to a complete outsider, shunning her family, Mr. Midgley said Mr. Chan had: “understood (Wang’s) philosophy, both her personal philosophy and her philosophy in running her businesses.”
Mr. Chan, a 48-year-old married businessman with mainly property interests, was believed to be Ms. Wang’s feng shui master, but Mr. Midgley told reporters that was overstated.
