The Lost Boys actor’s spouse of seven years, Susannah, cited irreconcilable differences in the papers filed in Los Angeles Superior Court on October 22.
Susannah has requested legal and physical custody of their five-year-old son Zen, with Corey paying spousal and child support, while having visitation rights.
Corey and Susannah married in 2002 - nine months after meeting in a nightclub - on the final episode of reality show The Surreal Life.
In 2007, Corey revealed how Susannah and his son had helped him overcome his depression and drug abuse problem.
He said: "Six years together and we're still in love. Whereas I used to get depressed or neurotic or dwell on things, I see my son's bright eyes and smile in the morning, and suddenly, I don't feel like I'm depressed anymore. There's nothing to be depressed about when you've got that."
Corey, 38, was previously married to actress Vanessa Marcil, from 1989 to 1993.
