The couple, who married in 2011, filed joint divorce papers in a court in Alaska, TMZ reported.
The joint filing by Track and Britta Palin indicates that the couple agreed on property and custody issues, according to TMZ.
The couple met in high school and have a 1-year-old daughter, Kayla.
Before filing for divorce, Track and Britta Palin were forced to watch a 48-minute video detailing how a split affects children, the gossip website reported.
Track Palin is a U.S. Army reservist who served in Iraq. He’s also a commercial fisherman and said he wants to go back to college, according to TMZ.
Track Palin said the Sept. 11, 2001, attacks spurred him to enlist in the Army, the Associated Press reported.
While supporting his mother on the 2004 presidential ticket, Track Palin spoke at his deployment ceremony in Fairbanks, Alaska, according to the AP.
Track and Britta Palin’s divorce filing comes three years after Sarah Palin and husband Todd Palin dealt with divorce rumors.
Levi Johnston, who fathered a child with Track’s sister, Bristol Palin, claimed at the time that Todd and Sarah Palin didn’t sleep together.
“I’ve never seen them sleep in the same bedroom,” Johnston said at the time, according to the Boston Herald. “There was a lot of talk of divorce in that house, and there were times when Sarah and Todd would mention it and sound pretty serious.”
The rumors proved to be false, as Sarah and Todd, whom the former governor often referred to as the “First Dude” of Alaska, are still married.
