(a) A person commits the offense of failure to support when he or she:
        (1) willfully, without any lawful excuse, refuses to
    
provide for the support or maintenance of his or her spouse, with the knowledge that the spouse is in need of such support or maintenance, or, without lawful excuse, deserts or willfully refuses to provide for the support or maintenance of his or her child or children in need of support or maintenance and the person has the ability to provide the support; or
        (2) willfully fails to pay a support obligation
    
required under a court or administrative order for support, if the obligation has remained unpaid for a period longer than 6 months, or is in arrears in an amount greater than $5,000, and the person has the ability to provide the support; or
        (3) leaves the State with the intent to evade a
    
support obligation required under a court or administrative order for support, if the obligation, regardless of when it accrued, has remained unpaid for a period longer than 6 months, or is in arrears in an amount greater than $10,000; or
        (4) willfully fails to pay a support obligation
    
required under a court or administrative order for support, if the obligation has remained unpaid for a period longer than one year, or is in arrears in an amount greater than $20,000, and the person has the ability to provide the support.
    (a-5) Presumption of ability to pay support. The existence of a court or administrative order of support that was not based on a default judgment and was in effect for the time period charged in the indictment or information creates a rebuttable presumption that the obligor has the ability to pay the support obligation for that time period.
