Unborn Child Support Act

This bill amends the Social Security Act to require states to establish child support obligations for the biological father of an unborn child when the mother requests it. Key provisions include allowing support to begin from the month of conception (as determined by a physician), permitting retroactive payments even if paternity is established after birth, and requiring court determination of payment amounts based on the mother's and child's best interests. It prohibits forced paternity testing for unborn children if it risks harm and explicitly bans any experimental programs from modifying these provisions. The bill directly affects mothers of unborn children and biological fathers, expanding child support enforcement to cover pregnancy.
