Attorneys are tackling the complicated job of dividing up Prince's estate.

The superstar musician was found dead on April 21 at Paisley Park, his famous home and recording studio in suburban Minneapolis. The first hearing concerning his estate is scheduled Monday in probate court.

Prince's full sister, Tyka Nelson, filed paperwork last week saying Prince had no known will. That means under Minnesota law, his estate would be divided among his surviving siblings.

Prince made hundreds of millions of dollars for record companies, concert venues and others, and he owned about $27 million in property in Minnesota.

A law enforcement official has told The Associated Press that investigators are looking into whether Prince died from an overdose and whether a doctor was prescribing him drugs in the weeks beforehand.
