If (i) the non-custodial parent was properly served with a request for discovery of financial information relating to the non-custodial parent's ability to provide child support, (ii) the non-custodial parent failed to comply with the request, despite having been ordered to do so by the court, and (iii) the non-custodial parent is not present at the hearing to determine support despite having received proper notice, then any relevant financial information concerning the non-custodial parent's ability to provide support that was obtained pursuant to subpoena and proper notice shall be admitted into evidence without the need to establish any further foundation for its admission.
Failure to report new employment or the termination of current employment, if coupled with nonpayment of support for a period in excess of 60 days, is indirect criminal contempt. For any obligor arrested for failure to report new employment, bond shall be set in the amount of the child support that should have been paid during the period of unreported employment.
An order for support entered under this Section shall also include a provision requiring the obligor and obligee parents to advise each other of a change in residence within 5 days of the change except when the court finds that the physical, mental, or emotional health of a party or of a minor child, or both, would be seriously endangered by disclosure of the party's address.
