Melbourne, Oct 1 : Heath ledger’s daughter Matilda may become world’s wealthiest girl if she wins 75 million court battle over the late actor''s life insurance.

Heath’s lawyer John LaViolette has sued the American ReliaStar Life Insurance company, as the firm has refused to pay out the 12.5 million dollar policy the ‘Broke Back Mountain’ star took out last June – seven months before his death.

Washington, Mar 09: Heath Ledger's father has insisted that the late actor’s daughter will be taken care of, in spite of being left out of his will.

The will, which was revealed on Saturday March 08, had been filed in Australia in April 2003, before Heath’s relationship with Michelle Williams and the birth of their daughter Matilda Rose in 2005.
