When Walt Disney passed away on December 15, 1966, he left behind an estate valued at several hundred million dollars, which was meticulously divided among his family and various charitable trusts. The primary heirs were his wife, Lillian Disney, and his two daughters, Diane Disney Miller and Sharon Disney Lund. A significant portion of Walt’s personal assets and his 10% share of The Walt Disney Company went into a family trust, with half dedicated to his daughters and the other half for the benefit of his grandchildren. While his brother Roy O. Disney took over the leadership of the company to ensure the completion of Walt Disney World, the financial inheritance became a complex legal matter for the subsequent generations. Upon Sharon’s death in 1993, the trusts established for her children became a source of high-profile legal disputes over staggered payments and "maturity" clauses. While the family's direct voting control over the company has diminished over the decades, the Disney heirs in 2026 remain some of the most influential philanthropic figures in the United States through foundations like the Walt Disney Family Museum.
