Prince's sister says musician had no known will

MINNEAPOLIS (AP) — Prince's sister says the superstar musician had no known will and filed paperwork today asking a Minnesota court to appoint a special administrator to oversee his estate, though the size of his fortune is unclear.

Tyka Nelson, Prince's only surviving full sibling, said in her filing that immediate action was necessary to manage Prince's business interests following his death last week. Prince made hundreds of millions of dollars for record companies, concert venues and others, and he owned about $27 million in property in Minnesota.

Nelson asked that Bremer Trust, a corporate trust company, be named administrator of the estate. The court documents say Bremer Bank provided financial services to Prince for many years. Nelson's filing said both Prince's assets and debts are unknown, but said he had "substantial assets" that require protection.

The filing comes less than a week after the pop star died Thursday at his home in suburban Minneapolis. The outpouring of grief and nostalgia prompted fans to buy 2.3 million of his songs in three days.

Prince owned a dozen properties in and around his famous Paisley Park complex in suburban Minneapolis: mostly rural pieces of land and some houses for family members. Public records show those properties were worth about $27 million in 2016.

Estimates of how much licensing his personal brand will bring in after death reach to the purple clouds.

"He was as big as they get," said Mark Roesler, chief executive of CMG Worldwide, which handles licensing for the estates of Marilyn Monroe, James Dean and other late stars.
