An act is done willfully if it is done voluntarily and intentionally with the purpose of avoiding a known duty under a state court order to pay a child support obligation. In determining whether the defendant acted willfully in failing to pay, you must consider whether the defendant had the ability to pay some portion of the past due child support obligation. Ability to pay means that the defendant had the ability, after meeting his basic subsistence needs, to pay some portion of the past due child support obligation.
