The AP analysis puts a net value on Jackson's 50 percent stake in the Sony/ATV catalog — his most prized asset — at $390.6 million. The 750,000-song catalog also includes music by Bob Dylan, Neil Diamond, Lady Gaga and the Jonas Brothers.
By putting the specifics of how he wanted his estate distributed in a trust rather than in the will itself allowed Jackson's wishes to remain private, lawyers said.
"Celebrities typically establish living trusts to avoid probate, which is a very public process," said Andy Katzenstein, a Los Angeles-based estate lawyer.
"In a trust you, the odds are it will never be made public and we'll never what was in it. The will, on the other hand, has to be made public," Katzenstein said.
The will does not specify how Jackson wanted to be laid to rest, fueling speculation about where Jackson might be buried.
A family spokesman Wednesday quashed a rumor that Jackson would be laid in state and possibly buried at Neverland Ranch.
"Contrary to previous news reports, the Jackson family is officially stating that there will be no public or private viewing at Neverland. Plans are underway regarding a public memorial for Michael Jackson, and we will announce those plans shortly," the statement read.
Jackson's three children Michael Joseph Jr., 12; Paris-Michael Katherine Jackson, 11; and Prince Michael Jackson, II, 7, known as Blanket, have been staying with their grandmother Katherine at the family compound in Encino, Calif., since Jackson's death last week.
Michael's father Joe Jackson was not named as a custodian of the children, but is married to Katherine and will therefore become a de facto guardian. Jackson regularly said in interviews that his father Joe had abused him as a child. Joe and Katherine remain married but are believed to be separated, with Joe spending much of his time living in Las Vegas.
On Monday, a California judge granted Katherine Jackson temporary guardianship of her grandchildren.
Jackson and Rowe, mother of Jackson's two oldest children, were briefly married following their son's Prince's conception 12 years ago, but divorced six months after daughter Paris' birth. Rowe gave Jackson custody of the children, but sued him in 2006 for breach of contract in an attempt to regain custody. The pair settled out of court for undisclosed terms and Jackson retained custody.
Despite reports that Rowe has not been close to the family for more than a decade and may not be biological mother of any of the children, she would still have "an advantage" should she seek custody, lawyer Gloria Allred told "Good Morning America," despite the will's naming of Katherine as sole custodian.
Rowe reportedly signed away her parental rights to the children after the divorce, but in 2006 an appeals court reestablished her parental status.
"Katherine would have to show it would be detrimental [to the kids for Rowe to have custody]. That's a very heavy burden," Allred said.
