A man involved in an inheritance wrangle with the woman he says is his sister is not a relative, a court heard yesterday. Chan Tin-lam claims he is the 'natural and lawful son' of the family and has taken his 'sister', Chan Lai-chun, to court seeking more than $1 million. Both are in their 50s. Ms Chan, who said she was an only child, testified that her parents died in the early 1990s. She said Mr Chan was the son of a friend of her parents and came from the mainland to live with her family in 1955 as her parents promised to take care of him. But Mr Chan left the family in 1966. After her father died in June 1990, she paid Mr Chan $200,000 to play the role of 'filial son' at the Taoist funeral and to perform a ritual believed to enable the soul to enter heaven, the Court of First Instance heard. The estate in dispute involves a residential property in Chatham Road, Kowloon, that was sold by Ms Chan for $2.45 million. Mr Chan says he is entitled to just over $1 million as his share. The case continues before Deputy Judge Gerard Muttrie.
