Prince's sister says the superstar musician had no known will and she's filed paperwork asking to be appointed executor of his estate.
Tyka Nelson filed the paperwork Tuesday in Carver County probate court in Minneapolis. Prince died at age 57 on Thursday at his estate in suburban Minneapolis. No cause of death has yet been released.
Nelson is his only surviving full sibling.
Nelson says in her filing that an emergency exists because immediate action is necessary to manage Prince's business interests.
With some $27 million in property and an outpouring of nostalgia over the pop star's death, Prince's heirs could stand to inherit a small fortune. The size of the fortune isn't clear, and recent disputes suggest money was tight.
