Michael Jackson may have left at least two wills, which can result in lengthy court battles for his fortune that is estimated at several million dollars, reports claim.

The ‘King of Pop’s former financial advisors claim the singer may have left at least two wills, British newspaper the Independent said quoting figures of his reported earnings and debts.

Jackson is estimated to have earned more than 400 million pounds since 1980s but saw his fortune ravaged by his own extravagant lifestyle and dozens of lawsuits. His estate reportedly includes earnings from his music estimated to be worth 30 to 60 million pounds and also his ownership rights of 251 Beatles songs, with top-selling songs such as ‘Yesterday’ and ‘Let it Be’.

Jackson bought the songs for 28.7 million pounds in 1985 in a deal widely seen as one of the greatest coups in the history of music business. Despite the sale of 50 per cent of the rights to Sony in 1995 for 60 million pounds, experts estimate the current value of the catalogue at 604 million pounds, the report said.

But what remains a mystery is the true extent of his wealth. At his death, some experts put his total debt at $400 million.
