Several family-members of the late music icon Prince are expected to attend a probate hearing Monday in Minnesota, where a court will begin determining disposition of the star’s estate.

Because the seven-time Grammy Award-winner left no known will or trust, Minnesota law specifies the estate be divided among his five half-siblings and his sister, Tyka Nelson, barring complications. Prince, who died April 21 at age 57, had no wife or known children.

ABC News said Sunday that Heir Hunters International, a Los Angeles company that searches for possible heirs to estates, has located a grandniece, the teenage granddaughter of Prince’s deceased half brother Duane Nelson. She would be entitled to her grandfather’s share, Minnesota attorney Chris Burns, who has no involvement in the estate, told ABC. The teen’s grandmother had no comment for the network when asked about the potential windfall.

Because Prince was generous with family, some siblings have experienced cash-flow issues due to the estate’s assets being frozen until probate is completed, TMZ.com said Sunday. The site said comedian-actor George Lopez, a friend of the late star, has anonymously advanced family members $20,000 to help cover living and travel expenses. Neither Lopez nor his representatives have commented on TMZ’s claim.

Also Sunday, Prince’s personal chef for nearly three years, Ray Roberts, told The Associated Press he felt the star “wasn’t himself probably the last month or two,” explaining that, “I think he was just struggling with being sick a lot.” Roberts said Prince was eating less and drinking less water than usual, and appeared to be losing weight.

Roberts said he last saw Prince the evening before the star’s death, when he prepared a roasted red-pepper bisque with a kale and spring-vegetable salad that Prince did not eat. Describing Prince as a “caring, thoughtful person” who treated employees like family, Roberts wiped away a tear, the AP reported, as he said, “I wish he was still here. That’s what it boils down to.”

Prince, born Prince Rogers Nelson, was found unresponsive in an elevator at his estate, Paisley Park, in the Minneapolis suburb of Chanhassen. While the Carver County Sheriff’s Office said it does not suspect foul play or suicide, it released a report Thursday indicating a criminal investigation has begun. The Star Tribune, of Minneapolis, said police were examining whether an overdose of opioids contributed to the star’s death.
