A Minnesota judge on Friday allowed Prince's blood to be DNA tested by the administrator of his estate in case anyone steps forward claiming to be related to the late music legend.
Carver County District Court Judge Kevin Eide said that Bremer Trust can obtain the blood being kept by Midwest Medical Examiner for genetic testing because "parentage issues might arise."
Prince, whose full name was Prince Rogers Nelson, died on April 21 at 57, but his only sister said he left behind no known will.
Prince's sister, Tyka Nelson, and his five half-siblings decided during a short court hearing last week that they would continue allowing wealth management firm Bremer Trust to serve as special administrator of the iconic musician's fortune.
Prince's estate is estimated to be worth about $300 million. The rights to Prince's brand are also unassigned, and it is rumored that he left behind thousands of unreleased songs.
In addition to his siblings, Prince is survived by two ex-wives. His only known child, a son named Boy Gregory, was just a week old when he died in October 1996.
