The star has one full sibling and five half siblings
Prince did not leave a will, his sister revealed in court documents.
Tyka Nelson, the only surviving full sibling of the musical icon, filed papers at a Minnesota state court petitioning for a special administrator to oversee her brother’s estate.
In her filing, Nelson said that immediate action is needed to run Prince’s business affairs, the AP reports. She asked that Bremer Trust, a corporate trust company, be named administrator.
Prince also leaves behind five half siblings who stand to share in his estate. The size of the late musician’s fortune isn’t known, but he is reported to have had about $27m (£18m) in property alone.
Prince died at Paisley Park on Thursday aged 57. He was found collapsed in a lift at his home, which doubled as a studio. He was pronounced dead at 10:07am on Thursday. A postmortem has been carried out but no cause of death has yet been confirmed.
The star’s remains were cremated after a private memorial service held at Paisley Park on Saturday.
Tributes to Prince have ranged far and wide with President Barack Obama stating “Today, the world lost a creative icon” and musicians including Madonna, Paul McCartney, Mick Jagger, Frank Ocean, The Weeknd and Katy Perry leading the tributes.
