The report states "Overeem is claiming [Golden Glory] duped him into signing the worst MMA contract ever and then tried to book him into high profile fights when he wasn't healthy enough to perform."
The lawsuit was filed in the L.A. County Superior Court. The suit states Overeem agreed to give his management 35 percent of his pre-tax income in exchange for services that were never rendered. TMZ's report also states Overeem claims "the managers have refused to pay him more than $151,000 in earnings -- including a bigtime bonus he was supposed to rake in when he signed with the UFC."
Overeem is allegedly suing for unspecified damages and is seeking a court order to break his contract with Golden Glory.
Overeem is set to face former UFC heavyweight champion Brock Lesnar on December 30th at UFC 141.
In a video episode as part his 'The Reem' series released on Monday, Overeem alluded to the problems he experienced with Golden Glory management that ultimately forced the split, but would not be any more specific than the discovery of discrepancies that resulted from having a lawyer look over his UFC contract.
