Sarah Palin's oldest son, Track, is filing for divorce from his wife. Track Palin and his wife, Britta, jointly filed divorce documents in an Alaskan court, which required they watch a 48-minute video about the impact of a failed marriage on a child.

Under Alaska law, by filing together, they signal that they have settled all property and custody issues, including child support. They have a one-year-old daughter, Kyla.

Track Palin and Britta married in 2011. He is an Army reservist and served time in Iraq. He works as a commercial fisherman and plans to go back to college.

Sarah has five kids: Trig, Track, Willow, Piper and Bristol Palin.
