On the eve of a hearing in the Michael Jackson estate, a lawyer for the singer's father filed a 60-page motion Monday that intensifies a bid to get money from his son's estate by making accusations of fraud against the administrators of his will.

Joseph Jackson's attorney, Brian Oxman, filed a blizzard of documents in court late Monday claiming that the singer believed his old friends John Branca and John McClain had defrauded him. He also accused both of conflicts of interest and said they should be removed from administering the will.

Joseph Jackson was omitted from his son's will with all of Michael Jackson's assets going to his mother, his children and children's charities.

Howard Weitzman, one of the attorneys representing Branca and McClain, issued a statement Monday night in response to the motion. A hearing on the matter is scheduled for Tuesday morning.

"These claims filed by Joe Jackson are so outrageous that they don't deserve any response," said Weitzman.

It was unclear whether Joseph Jackson has the legal standing to challenge its provisions.

Oxman said in a phone interview that the father is allowed to challenge the executors as "an interested party who has the right to be an executor or personal representative."

Most of Oxman's accusations were aimed at Branca, the attorney who represented Jackson for more than 20 years and is seen as the architect of his financial empire. Branca parted ways with Jackson in 2006 and then returned to work with him shortly before the singer died.

Oxman claimed that Jackson believed Branca had committed "crimes" against him including embezzlement and funneling money into offshore accounts. But Oxman acknowledged in the interview Monday night that may not be true.
