The filing was made by the 55-year-old Todd, who cited "incompatibility of temperament." It adds that the Palins were unable to live together as a married couple. News of the divorce comes just over a week after Sarah and Todd's 31st wedding anniversary. Sarah, who served as Governor of Alaska from 2006 to 2009, has not commented on the divorce. Neither has Todd, who was once referred to as the "first dude of Alaska." The Palins have five children together, including an 11-year-old named Trig. The divorce filing from Todd asks for shared custody of the child. It also requests that the family's assets be separated equally.
