His sister Tyka Nelson has now asked the court to rule that the vast fortune be split between herself and her five half-siblings.
The legendary singer, who died on April 21 at just 57, is said to have been paranoid about contracts after having legal wrangles earlier in his career.
As a result, sources say he jumped from lawyer to lawyer almost every year and it was almost impossible to get his signature on any legal documents.
Minnesota-based attorney Stephen Hopkins says it’s unusual for a person of Prince’s stature and wealth to die without a will. In such cases, assets are split evenly between the heirs, he says.
“This case is going to be open for some time, probably for some years,” he adds.
He says the administrator’s first job will be to ascertain all of Prince’s assets, paying any debts he owed and paying taxes.
Tyka and Prince had become closer than ever in recent years after a difficult stretch when Tyka was addicted to crack cocaine and prostituting herself to support her two young sons, say reports.
Meanwhile, Tyka’s husband Maurice Phillips, is hoping Prince’s former Minneapolis home, Paisley Park (below), will eventually be opened to the public as a museum.
“We will turn Paisley Park into a museum in Prince’s memory,” he tells the Sun.
“It would be for the fans. He was all about the fans – this would remember his music, which is his legacy.”
