Cher and Sonny had marital problems since late 1972, but appearances were maintained until 1974. "The public still thinks we are married," Sonny wrote in his diary at the time, " that's the way it has to be." In February 1974, Sonny filed for a separation, citing "irreconcilable differences". A week later, Cher countered with a divorce suit and charged Sonny with "involuntary servitude", claiming that he withheld money from her and deprived her of her rightful share of their earnings. The couple battled in court over finances and the custody of Chaz, which was eventually granted to Cher. Their divorce was finalized on June 26, 1975.
