Former Alaska Gov. Sarah Palin's husband Todd Palin has filed for divorce in Anchorage Superior Court.
Citing "incompatibility of temperament between the parties such that they find it impossible to live together as husband and wife," the court document, filed on Friday, uses initials instead of full names, but lists the date of the Palin marriage and the birth date of their child, Trig, 11, who had Down Syndrome, for whom they filed joint custody.
Anchorage attorney Kimberloo Colbo is representing Todd, 55, and has asked the court to keep the case confidential. As well as Trig, the couple has four adult children, Track, 30, Bristol, 28, Willow, 25, and Piper, 18.
Sarah Palin, also 55, rose to prominence during the 2008 presidential election, when the former mayor of Wasilla was chosen by John McCain as his vice presidential candidate, a decision for which the Arizona senator expressed regret last year. The photogenic couple - he was known in Alaska as the "First Dude" and was a champion snowmobile racer - were an immediate media sensation.
