Tony Chan says Nina Wang wanted her money to go to him
Hong Kong feng shui master Tony Chan has filed an appeal after his claim to the multi-billion dollar estate of the late tycoon Nina Wang was rejected.
The High Court ruled in February that the will Mr Chan had put forward was forged and awarded her fortune to the Chinachem Charitable Foundation.
Nina Wang died in 2007, the owner of high-rise towers and companies around the world.
The fight over her estate has captivated the Hong Kong public.
Tony Chan, Nina Wang's former lover, claimed her estimated $4.2bn (£2.8bn) estate based on a will allegedly written in 2006.
But the High Court deemed it a fake and awarded her estate to the Chinachem Charitable Foundation, run by Ms Wang's family.
The battle over Nina Wang's will has captivated the Hong Kong public
Tony Chan was subsequently arrested and is out on bail until June. The 2006 will is to be tested to see if it is a fake.
On Friday Mr Chan filed an appeal. He said earlier the will was genuine and was given to him personally by Ms Wang.
During the hearings in the High Court earlier this year Tony Chan presented the pigtails of the late eccentric billionairess, who was known for her plaited hair and miniskirts and nicknamed Little Sweetie.
He also gave diary dates of their alleged sexual trysts.
The battle of the wills has eerie echoes of how Nina Wang fought with her father-in-law over her husband's fortune.
Her husband, chemical magnate Teddy Wang, was kidnapped twice, the second time in 1990, when he did not return.
Nina Wang was accused of forging her husband's will and the estate initially went to her father-in-law, but that ruling was overturned and she received his fortune in 2005.
