The court may assess filing fees, reasonable attorney's fees, fees for genetic testing, other costs, necessary travel expenses, and other reasonable expenses incurred in a proceeding under this Act. The court may award attorney's fees, which may be paid directly to the attorney, who may enforce the order in the attorney's own name. The court may not assess fees, costs, or expenses against the support-enforcement agency of this State or another state, except as provided by other law.
The judgment shall contain or explicitly reserve provisions concerning any duty and amount of child support and may contain or explicitly reserve provisions concerning the allocation of parental responsibilities or guardianship of the child, parenting time privileges with the child, and the furnishing of bond or other security for the payment of the judgment, which the court shall determine in accordance with the relevant factors set forth in the Illinois Marriage and Dissolution of Marriage Act and any other applicable law of this State, to guide the court in a finding in the best interests of the child. In determining the allocation of parental responsibilities, relocation, parenting time, parenting time interference, support for a non-minor disabled child, educational expenses for a non-minor child, and related post-judgment issues, the court shall apply the relevant standards of the Illinois Marriage and Dissolution of Marriage Act. Specifically, in determining the amount of a child support award, the court shall use the guidelines and standards set forth in subsection (a) of Section 505 and in Section 505.2 of the Illinois Marriage and Dissolution of Marriage Act. The court shall order all child support payments, determined in accordance with such guidelines, to commence with the date summons is served. The level of current periodic support payments shall not be reduced because of payments set for the period prior to the date of entry of the support order.
For purposes of determining the amount of child support to be paid for the period before the date the order for current child support is entered, there is a rebuttable presumption that the net income of the person obligated to pay support for the prior period was the same as the net income of the person obligated to pay support at the time the order for current child support is entered.
If (i) the person obligated to pay support was properly served with a request for discovery of financial information relating to the ability to provide child support of the person obligated to pay support; (ii) the person obligated to pay support failed to comply with the request, despite having been ordered to do so by the court; and (iii) the person obligated to pay support is not present at the hearing to determine support despite having received proper notice, then any relevant financial information concerning the ability to provide child support of the person obligated to pay 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.
