While it’s still not clear who will inherit Prince’s Paisley Park estate and net worth, new reports suggest that his younger sister, Tyka Nelson, could be first in line. However, Nelson will likely get her late brother’s fortune only in the event that Prince did not have a will at the time of his death.

Minnesota law states that the first person to inherit someone’s fortune after one's death, in the absence of a will, is a spouse, followed by children. Prince, who died at the age of 57 Thursday in his compound, was not married at the time of his death. It’s also believed that he didn’t have any living children. The iconic singer did have one child, a son named Boy Gregory, but the baby died one week after his birth from a rare genetic disorder called Pfeiffer syndrome.

Based on the law, the deceased person’s net worth would then go to grandchildren, parents, siblings or “more distant relatives if there are no closer ones.” Prince’s parents died more than a decade ago, which means Nelson could be given Prince’s fortune, estimated to worth more than $300 million.

According to the Sun, Nelson and Prince grew closer over the past few years, but they did have a rocky relationship at first. In a 2003 interview, Nelson opened up about her strained relationship with her famous brother and admitted that she struggled with addiction and prostitution.

“I was a single mother, and my boys were babies,” she said. “I sold my body for food, money and Pampers. I pawned the car Prince had given me and sold the kids’ TV for drugs.”

As far as her bond with Prince, Nelson offered: “I love my brother. But I’m not a yo-yo. He can’t just keep spinning me in and out of his life.”

Nelson was pictured at Prince’s Paisley Park on Friday wearing purple hair in honor of her brother. Even though it hasn’t been revealed whether the “Purple Rain” singer had drafted a will, celebrity attorney Dan Streisand told Reuters it’s highly likely  Prince did indeed have one, given his massive wealth and fame.

“Hopefully, Prince executed a trust and indicated his intentions, both with respect to who his trustee would be and how he would want the estate to be disposed of,” Streisand said (via Page Six). “Prince was an incredibly smart person, he had great legal representation … so I would suspect that somebody along the way said, ‘Look, we’ve got to get you to execute some documents.’”
