Ledger's Uncles: Michelle Williams May Have to Fight for Daughter's Inheritance

Heath Ledger's former partner Michelle Williams has been warned she may have to fight to ensure her infant daughter receives part of her famous father's fortune.

Two of Ledger's uncles sensationally turned on the actor's father Saturday amid revelations the 28-year-old made a will leaving his wealth to his parents and sisters.

Reports have surfaced that a three-page will, lodged with a Manhattan court, was written three years before Ledger's beloved daughter Matilda Rose was born.

Ledger's uncles Mike and Haydn accused Heath's father Kim of mismanaging their grandfather's estate to the tune of $2.5 million.

They also said they had raised fears for Matilda's future with her Sydney-based grandfather Larry Williams.

The uncles estimated their nephew's estate would be worth $20 million after his earnings from the latest "Batman" movie were calculated.

Larry Williams declined Saturday to comment about the warning, but said he was astonished to learn Ledger — who died from an apparent drug overdose in his New York apartment in January — had even made a will.

"It doesn't make any sense because Heath professed many times his love for Matilda; it makes no sense that he would not leave anything for his daughter," he said. "He just wasn't that type of person."

Kim Ledger moved quickly to deny his granddaughter and Michelle Williams would be left without an inheritance and said Matilda was his family's absolute priority.

"Matilda is our absolute priority and Michelle is an integral part of our family ... They will be taken care of and that's how Heath would want it to be," Kim Ledger says in the statement.

But Kim Ledger's brothers said they were so concerned they had advised Larry Williams to tell his daughter to hire a lawyer and Haydn Ledger said his concerns had been passed on to Michelle Williams' mother in the U.S.

"I'm concerned for Matilda. I have concerns about the distribution of funds," Haydn Ledger said.

"We pointed out to Larry just to be on guard. I had to say this about my brother. I don't care anymore. If Heath was alive we would never ever do it (speak publicly), (but) when Heath died we could see what could happen."

Mike Ledger also spoke out about his conversations with Larry Williams.

"We spoke to Larry about Kim and his ability to manage Matilda's assets," he said. "Our concern is that it doesn't happen to another family.

"We said to Larry it would be worthwhile to have a lawyer look into the issues."

Haydn Ledger said the fallout from the fight over their grandfather's estate in 1994 created a terrible strain between himself and his brother.

"Kim was in position of guardianship and we had to take him to court to take that off him because a sum of $2 million went missing," he said.

Kim Ledger could not be contacted about his brothers' claims Saturday night.
