The "Big Bang Theory" actress filed for divorce late Friday in Los Angeles Superior Court citing irreconcilable differences, and her petition was released Monday afternoon.
Cuoco and tennis pro Ryan Sweeting married in a New Year's Eve ceremony in 2013. They have no children together.
The divorce petition states the pair signed a prenuptial agreement in November 2013 that will dictate Cuoco's spousal support payments to Sweeting and how they will divide their assets.
The filing states Cuoco and Sweeting separated earlier this month, but it provides no further details about the breakup.
Cuoco's publicist said Friday that the couple had mutually agreed to end their marriage.
"Kaley Cuoco and Ryan Sweeting have mutually decided to end their marriage," Cuoco's rep said. "They ask for privacy at this time. No further statement will be issued regarding this matter."
More than 18 million people tuned in Sept. 21 when "Big Bang Theory" returned for its ninth season.
