A source told Contact Music that after Johnny passed away on Sept. 12, 2003, his estate was divided up among his children, though not equally. Apparently, Johnny's four daughters from his first marriage: Rosanne, Kathy, Cindy, and Tara, were left $1 million each which is no small potatoes, until you consider how much the singer's estate was worth. "At the time of his death, Johnny had an estimated wealth of between $60 and $100 million," via Express UK.

The royalties for Johnny's songs, most notably Ring of Fire, all went to his son John Carter Cash who is responsible for all the decisions made regarding his father's estate. "My dad started something in motion within his lifetime, with integrity, heart, purpose, and morality in his decision-making in the way he ran his business," John told The Nashville Ledger in 2012. Since his father's death, it has been John's job to keep the business of Johnny Cash alive.
