The actor, who died at the age of 28, of an accidental prescription drug overdose in February, wrote a three-page will, while he was in his native country, Australia in 2003.

As the will was written before the actor met Michelle Williams, his ex-wife and their 2-year-old daughter, Matilda Rose, are not mentioned in the document. It seems that Ledger had around $145,000 in New York assets at the time of his death, including a $25,000 Toyota Prius, $100,000 shared in various bank accounts and about $20,000 in furniture and fixtures.

The real size of his total wealth is not known, nor is the value of his Brooklyn house, that he used to share with Michelle Williams and their child. It is also uncertain whether there will be any provisions for the actor’s former wife and his daughter.

Michelle Williams, 27, and Heath Ledger, 28, met on the set of the 2005 movie "Brokeback Mountain," fell in love and had Matilda, who is now 2 years old.

Ledger’s lawyer, Harvey Corn, asked a judge to seal the documents, in order to protect the family’s privacy, while Mara Buxbaum, Ledger’s spokesperson, refused to comment.

In an interview for Elle magazine, a few days before Ledger’s death, Michelle Williams had eventually revealed her feelings concerning the break-up with the “Brokeback Mountain” actor.

“[Heath and I] had broken up – way before it became a news story - and I didn’t know where to go. I couldn’t imagine any place in the world that was gonna feel good to me,” she said, referring to her move to Portland, for the film role in „”Train Choir.”

“Whatever I’ve suffered, I feel like the work I get to do is an absolute blessing” she added. “Because whatever I feel inside, it has a place to go. It just saves me over and over again.”

After Heath Ledger’s death, Michelle Williams issued just one statement in which she asked for privacy.

"Please respect our need to grieve privately," Williams said. "My heart is broken. I am the mother of the most tender-hearted, high-spirited, beautiful little girl who is the spitting image of her father. All that I can cling to is his presence inside her that reveals itself every day."

Also, last month it was announced that Terry Gilliam’s “The Imaginarium of Doctor Parnassus”, the movie on which Heath Ledger was working at the time of his death, will be salvaged through the participation of actors Johnny Depp, Jude Law and Colin Farrell.

Johnny Depp, Jude Law and Colin Farrell have all signed on to play Ledger's character, ‘Tony,’ in the film. This is possible because the script, penned by Terry Gilliam and Charles McKeown, has Ledger’s character travel to three magical worlds through a magical mirror; in each world, he will be incarnated by one of the three new cast members.
