The couple has been married 10 years. They have three children, including twins Tatum and Drew. Tatum was treated for a form of eye cancer in 2007 while Fisher was playing for Utah. Fisher played 18 seasons in the NBA, winning five titles with the Lakers.
Fisher, who filed papers in Los Angeles Wednesday, issued a statement. "This is a difficult time for me personally. For the sake of our children, I ask that everyone respects our privacy during this process."
