Life appears to be imitating art for actor Jon Cryer.

On "Two and a Half Men," he plays a divorced, check-writing dad, and now his real-life courtroom battle reads like a scene straight out of his hit TV show.

According to court documents obtained by ABC News, Cryer's ex-wife, Sarah Trigger, claims that since her custody of their 13-year-old son Charlie has jumped from 4 percent to 50 percent, her child support should go up too - from $8,000 a month to nearly $90,000 a month.

"This is the tale of two separate lifestyles that which Charlie experiences," the petition reads. "Currently Charlie experiences two different lifestyles depending on which parent he's with. Fifty percent of the time Charlie is able to compete with his peers on a level playing field and the other 50 percent of the time Charlie is not able to compete on a level playing field."

Trigger said an increase in child support will allow her to "maintain continuity of lifestyle" and provide their son with suits, a cell phone, a cello, summer camp and more. The out-of-work actress is asking that her son have what classmates at his prestigious school have: birthday parties with trampolines and exotic vacations to Europe and Thailand.

"Her arguments is, 'Oh, when they go to the mother, they're with a poor relative and when they go to the father, he's rich," celebrity divorce attorney Raoul Felder told ABC News. "But that's not a valid argument under the law."

Cryer and Trigger split in 2004 after five years of marriage. She claims in court documents that while her acting career has stalled, Cryer earns $2 million a month on the long-running sitcom.

"Currently, I am unemployed. Petitioner is highly successful actor who I believe earns approximately $2,000,000 per month," Trigger writes in the petition, in which she also asks Cryer to pay for her attorney's fees.

Neither is speaking publicly about their court fight. Cryer did not respond to ABC News' request for comment and Trigger declined to comment.
