On October 13, 2021, Cher filed a lawsuit in Los Angeles federal court claiming that when they divorced, she and ex-husband Sonny Bono agreed to share any royalties earned from songs they recorded together. Cher is suing former Representative Mary Bono, Sonny's fourth wife whom he was married to when he died, claiming she "has undone" the singer and actress' ownership to the songs and right to the royalties, according to ABC7. Cher is seeking at least $1 million in her lawsuit.

At the time of his death in 1998, Sonny was serving in the United States House of Representatives as a California congressman. His wife, Mary, ran for his seat after he passed and served in the House from 1998-2013.

In 1998, Cher was also much closer to the Bonos, and when she delivered his eulogy it was clear how much she would miss her first husband when she said, "When I was a young there was this section in Reader's Digest called 'The Most Unforgettable Character I Ever Met.' No matter how old I get, no matter how many people I meet, that person will always be Son for me" (via Biography)
