ANCHORAGE, Alaska — Sarah Palin’s oldest daughter, Bristol, is seeking child support from the young man who fathered her 1-year-old son.

Documents filed Thursday in Superior Court in Palmer shows Bristol Palin is seeking $1,750 a month from 19-year-old Levi Johnston, her former fiancee. Their son, Tripp, was born in December 2008.

Palin attorney Thomas Van Flein said Alaska law makes clear that a parent of a child is obligated to provide support.

“It is unfortunate Bristol has to seek court intervention in this regard,” Van Flein said.
