The father of Heath Ledger's ex-girlfriend Michelle Williams has challenged the late actor's family to publicly state the value of their son's fortune.
Larry Williams, who is one of the world's best known stock market traders, said he was perplexed that documents filed in a New York court listed Ledger's assets at just $145,000.
Michelle Williams and Ledger have a daughter, 2-year-old Matilda. Larry Williams, the toddler's grandfather, issued the challenge to Ledger's father Kim Ledger through The Sunday Telegraph.
"It's real simple: just come clean with everything,'' he said. "It's so easy to resolve this. He just has to say where the income went and where the assets are.
"I'm certain that there is grieving in the Ledger family but (lawyers for) Kim have already filed papers in New York, so it seems like it's time to be transparent about it. I have no idea what Heath Ledger was worth (but) they certainly haven't stated all of the assets to the court.''
Williams conceded that he did not have a close relationship with his daughter and that he was not in constant contact with her.
Heath Ledger, 28, died in New York on Jan. 22 of an accidental overdose of prescription drugs.
