Things are heating up in the battle for Prince’s estate. After a judge confirmed that the “Purple Rain” singer did, in fact, die without a will in place, questions have emerged about who may inherit his assets. His sister Tyka Nelson is reportedly vying to be put in charge of the estate — but does she stand a chance?

TMZ reports that Tyka and Prince’s five half-siblings met on Thursday to discuss the division of his money, among other things. The Grammy award winner’s sister reportedly stormed out of the meeting after butting heads with others in attendance. Sources claim the tense meeting took nearly two hours. During the sit-down, Prince’s half-brother Alfred is said to have confronted Tyka about her decision to exclude him from the memorial service held at Paisley Park on April 23. This confrontation was reportedly the tipping point of the meeting, sending Tyka into a rage. TMZ’s sources also report that a decision was made during that meeting regarding who will be administrator of Prince’s estate — and it’s not Tyka. A bank representative is thought to be currently in charge.

While Prince’s family reportedly feuds over his belongings, investigators are said to be diving deeper into what may have caused his death. On Thursday, police issued a search warrant for the “When Doves Cry” singer’s Minnesota home. TMZ reported that authorities in Carver County are being careful not to disclose too much information about their reason for issuing the search warrant to avoid tainting the investigation. Rumors have been swirling that Prince’s death is being investigated as a drug overdose.

Prince’s lawyer, L. Londell McMillan, has addressed stories claiming the singer had abused Percocet at times during his life. On Wednesday, he told the Associated Press that his client lived a clear lifestyle, was known for being vegan and avoided foul language. McMillan maintained that the world-renowned artist may have been taking medications during his lifetime but was in no way abusing them.

No decision has been made about who will get Prince’s money — and other belongings — following his shocking and sudden death on April 21. Tyka is said to have submitted legal paperwork to the courts in the hopes of being named administrator to her brother’s estate, though if there is truth to TMZ’s reports, that request has been denied.
