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

A court document filed Thursday says Bristol Palin is seeking $1,750 a month from Levi Johnston. It says Bristol is providing nearly 100 percent of Tripp's care, and that Johnston has paid only $4,400 in more than a year.

Johnston lawyer Rex Butler says on several occasions his client wanted to give Bristol money for the baby's care, requesting that she bring Tripp with her, but she was a no-show.

Palin was the Republican candidate for vice president when it was revealed her daughter was pregnant. Palin said the teenage couple would marry and they both appeared at the nominating convention, but later separated.
