The former 'Frasier' star is said to have filed the papers in Los Angeles Superior Court in a bid to block the former Playboy model having access to his assets from the Screen Actors Guild, the Directors Guild of America, Equity League, AFTR Health & Retirement Funds, Producers Pension Plan, and Gramnet Inc, the couple's production company.
According to website RadarOnline.com, the documents claim Kelsey is seeking "an order determining the nature and extent of both employee and non-employee spouse's interest in employee benefits under the plan, an order restraining claimant from making benefit payments to employee spouse pending the determination and disposition of non-employees spouse's interest if any, in employee's benefits under the plan".
Although Kelsey recently got engaged to flight attendant Kayte Walsh he is still legally married to Camille, although their marriage is set to officially end next year.
Although Camille - who has daughter Mason, nine, and son Jude, six, with Kelsey - recently hit out at the star for the way he ended their 14-year union, but said she hopes they can be friends again one day.
She said: "Kelsey's made some very selfish choices that broke up our home. He didn't destroy us, but he broke up our family.
"I'm so blessed to have these children in my life, and I thank Kelsey for that.
"I want him to be happy. At some point, when the hurt goes away, I hope we can be friends again."
