O'Neal split from his spouse in September 2007 and accused Shaunie of being secretive about her assets.
In his divorce petition, he said, "The marriage... is irretrievably broken."
The couple reunited in August 2008 and vowed to work through its problems, but the star's attempts have failed to impress Shaunie and she filed new papers in Los Angeles County Superior Court on Monday (09Nov09).
According to TMZ.com, Shaunie has moved her and their four young kids out of their shared home in Florida and relocated to California.
She is seeking spousal and child support as well as legal and physical custody of their children. They also have a kid each from previous relationships.
The couple would have celebrated its seventh wedding anniversary next month (Dec09).
