High Court Justice Andrew Macrae said Peter Chan's attempt to pass himself off as the beneficiary of Nina Wang's fortune, estimated by prosecutors at 83 billion Hong Kong dollars, was "shameless, wicked and borne of unparalleled greed."
Wang, once Asia's richest woman, died in 2007 at age 69 after battling cancer.
Hong Kong police charged Chan after a 2011 court ruling that a will purportedly leaving Wang's Chinachem Group to him was forged.
Chan, a 53-year-old father of three, was convicted yesterday of forgery and using a false instrument. The judge sentenced him to 12 years on each count, to be served concurrently.
Chan is a former feng shui master who changed his name from Tony after converting recently to Christianity.
The judge said Chan was not content with the USD 387 million that Wang had given to him while she was alive and decided to claim her business empire and estate as well.
"I have no doubt you are nothing more than a clever and no doubt beguiling charlatan," Macrae said in sentencing Chan, who rocked back and forth with a pained expression while his wife wept quietly in the public gallery.
"Instead of benefiting mankind as Nina Wang wanted, the only one to benefit would have been you," the judge said. In the earlier court ruling, a judge upheld another will bestowing the fortune on Wang's Chinachem Charitable Foundation.
Wang inherited developer Chinachem after her husband was kidnapped in 1990. He was never found despite a $33 million ransom his family paid. She built the company into a huge property developer, with office towers and apartment complexes throughout Hong Kong.
