Jon Cryer's Ex Demands More Child Support

"Two and a Half Men" star's ex-wife argues child support should be increased with increased custody.

High stakes child support demands from the actor John Cryer's ex-wife. She's asking for nearly $90,000 a month for their 13-year-old son; that's more than 10 times what he usually pays. ABC Cecilia Vega with the story.

He plays the divorced check-writing dad on 'Two and a half men'. But this morning, John Cryer's real life courtroom battle reads like a scene-straight hour of hit TV show.

'Well, um, I, I figured as long as I was here that I would give you your last, and final out-of-money check.”

According to court documents, Cryer's ex-wife Sarah Trigger says that since her custody of their 13-year-old son jumped from 4% to 50%, her child support should go up too, from $8,000 to nearly $90,000 a month. The out-of-work actress says she needs the money, so the boy can keep up with the rich kids in their Los Angeles neighborhood. So what does a son of Hollywood star need? Suits, a cell phone, a cello, summer camp, and it doesn't end there. Trigger says in those court documents. She wants her son to have what classmates at his prestigious school have: birthday parties with trampolines, exotic vacations to Europe and Thailand.

Her argument is:"Oh when they go to the mother, they’re visiting a poor relative, wonder when the father is rich. But that's not a valid argument under the law.

The couple split in 2004. Cryer did not respond to our request for comment, and Trigger said no comment. While neither is speaking publicly about this court fight, Trigger claims in court documents that while her acting career has stalled, Cryer earns $2 million a month.
