Before Prince's millions are divvied up among his heirs, a Minnesota judge is holding a second hearing to determine the procedures for deciding who is an actual blood relative — possibly even a child — of the late musician.

Prince died in April of a drug overdose, and no will has been found. He had no known children, but left behind a sister, Tyka Nelson, and five half-siblings, who now stand to inherit an estate worth up to $300m (£223m; 272m euros).

Carver County District Judge Kevin Eide will hear arguments in his suburban Minneapolis courtroom on Monday (27 June) to discuss protocols for determining who is an heir, including procedures for DNA testing. The determination of specifically who has a claim on the estate will be made at future hearings.

Several people have claimed to be related to Prince since his death.

"There will be many coming forward claiming that they are siblings. There will be some that will be claiming they are children. That's where the DNA comes into play," local estate planning attorney Jeff Molever told KARE-TV.

Two claim to be a niece and grandniece, claiming that they are descendants of the late Duane Nelson Sr, who is widely considered to be Prince's half brother. The two may not have been related by blood, but Nelson was raised by Prince's father, which lawyers may argue could be enough to grant his descendants some kind of standing.

In addition, a number of people say they are Prince's children, Eide will have to determine how DNA tests will be conducted. Without a will, children are first to inherit. A DNA test has already ruled out a Colorado prison inmate who claimed to be his son.
