Melbourne, July 15 : Having left his entire estate to his parents and three sisters, an Australian court will decided how much of a share Heath Ledger’s daughter Matilda Rose will get.

Ledger had made the will before Matilda''s birth, so its executors have now applied for probate in the West Australian Supreme Court in Perth, Daily Telegraph reported.

Even though in his will the late actor had bequeathed his immediate family, they have been advised that under WA law, that the toddler is entitled to receive the major portion of the estate.

But to do so her mother, actress Michelle Williams, will have to officially lodge a claim with the court supported by an affidavit, which according to legal experts could end up in the public domain.

The executors of Ledger''s estate, businessman Robert Collins and accountant Mark Dyson, late last week advertised in Perth''s daily newspaper for "creditors and other persons" having claims on the estate to lodge them by August 11.

This is to ensure all debts are paid before the estate is distributed, local lawyer Edwin Abdo revealed.

At the time of his death, the documents filed in a New York court after Ledger died in January, stated that he only had 145,000 dollars worth of assets in the US.

But it has now been revealed that his entire fortune, mostly held in Australian trusts, is likely to be worth up to 20 million dollars.

There were no comments from Mr Dyson on July 14 upon the matter. (ANI)
