Prince’s family has begun the process of dividing up the singer’s sizeable assets.

The iconic musician left no known will and his assets are estimated to be worth about $100 million.

Prince died at his Paisley Park compound outside Minneapolis, Minnesota, on April 21.

The singer’s sister, Tyka Nelson, and half-siblings are the apparent heirs to his estate, authorities have said.

Tyka Nelson and Prince’s half-sibling Alfred Jackson attended a hearing on May 2 at the Carver County courthouse in Minnesota, where lawyers began surveying the singer’s estate.

If no will is found, the state will determine how the money is divided up.

During the short hearing, Judge Kevin Eide formally appointed Bremer Trust National Association as the special administration to oversee Prince’s probate case.

One attorney said there was an “ongoing search” for a will.

Investigators are still determining how Prince died at the age of 57.

Prescription painkillers were in Prince’s possession when he died. However, it is unclear what role, if any, those drugs may have played.

A law enforcement official confirmed to the Associated Press that investigators were looking into whether Prince died from a drug overdose and whether a doctor was prescribing him drugs in the weeks before his death.

According to ABC News, a vault containing unreleased Prince’s songs was found at his estate and will be drilled open by the company with temporary authority over his estate.

Prince told The View about his unreleased music in 2012.

Enough music was apparently left behind to release an album a year for the next century.
