"George was very close to his sisters, and the understanding is that they’re going to inherit most of his wealth, par­ticularly Melanie who he was incredibly close to," a source told The Sun. "She was there at many of the big milestones in his life, and was there by his side until the very end. George was very family-orientated and even in his death he’s shown that. He was keen to see them well looked after for the future."

Michael worth between $125 million and $200 million at the time of his death. Sources think he may also have left part of his estate to his father, his boyfriend Fadi Fawaz, and his godchildren. The generous Michael may also have designated some of his money for charity.
