Days after the boxing icon's death, attention has turned to his will, and how it will divide his estimated $80 million fortune.
Muhammad Ali’s widow, Lonnie, and his nine children may become locked in a bitter legal battle over The Champ’s estate, believed to be worth $80 million.
The boxing icon has been married four times.
His first marriage to Sonji Roy in 1964 lasted just a year-and-a-half and produced no children.
He married his second wife, Belinda, when she was just 17 in 1967. They had three daughters – Maryam (born 1968) and twins Jamillah and Rasheda (born 1970) and a son, Muhammad Ali, Jr. (born 1972).
Two years ago, Inside Edition found Muhammad Jr. in Chicago and doing odd jobs for a living.
In 2014, he spoke of his bitterness toward his stepmother: “I asked my stepmother why don't you let him come out to see me? She says I don't want him to see how you live. I said why not? Maybe he could help me?”
In 1975, he had an affair with Veronica Porsche, whom he married in 1977.
He had two more daughters with his third wife: Hana, who was born at the time of her parents' wedding and Laila, born in 1977. Laila would go on to carry her father's name in the ring as a professional fighter.
He married his fourth wife and widow, Lonnie, in 1986 as Parkinson’s disease began to take hold. They adopted a boy, Asaad.
Much of Ali's fortune comes from the sale of the commercial rights to his name for $50 million.

His friend Tim Shanahan, who wrote Running With The Champ about his friendship with the former boxer, says he wanted to share that money.
“He always loved money, he also had disregard for money. He always wanted to make it but he always wanted to give it away. His goal was to make money so he could give it away. He was always concerned about poor people and starving children," he told Inside Edition.
Estate law expert Herb Nass says Ali's children may have few options if they aren't happy with their inheritance.
“Legally they have limited rights,” he said. “They really don't have a lot of rights as children, to his estate.”
