News outlets report Sweeting filed court documents last week requesting spousal support and for Cuoco to pay his attorney's fees. The 28-year-old tennis player also wants to terminate the court's ability to award the 29-year-old actress support.
Cuoco, who stars on the CBS sitcom The Big Bang Theory, is worth an estimated $45 million, while Sweeting, a professional tennis player, is worth $2 million. The pair were expected to honor their prenup, which dictates the terms of spousal support.
Sweeting claimed the couple's date of separation was Sept. 25, 2015, the day word of their impending divorce broke, but Cuoco listed Sept. 3 when she filed the papers. The former couple got engaged after three months of dating, and married in December 2013.
Cuoco shot down dating rumors last week amid speculation she and ex-boyfriend Johnny Galecki had reconciled. She and the 40-year-old actor play Penny and Leonard on The Big Bang Theory, respectively, which airs Mondays at 8 p.m. ET.
