A party incurs an expense even if a third party pays the expense on the party’s behalf, as long as the party would otherwise be legally obligated to pay the expense. Thus, costs and reasonable attorney fees that a third party paid on behalf of a litigant can be recovered under NRS 17.115(4) and NRCP 68(f)(2). In addition, a party can recover expert witness fees even if the expert did not testify at trial and was not deposed.
