12-819.Limitations on Part 8 of Article XII.

Section 12-819 marks the outer boundary of Part 8. Its wage deduction machinery -- the affidavits, interrogatories, the Section 12-803 formula, the employer's duties, the trial and hearing procedures -- does not apply to orders for withholding of income that a court enters under a separate list of family-support statutes: the Illinois Public Aid Code, the Illinois Marriage and Dissolution of Marriage Act, the Non-Support of Spouse and Children Act, the Non-Support Punishment Act, the Revised Uniform Reciprocal Enforcement of Support Act, the Illinois Parentage Act of 1984, and the Illinois Parentage Act of 2015, when those orders provide for the support of a child or maintenance of a spouse.

The effect is that a support or maintenance withholding order entered under any of those statutes runs on its own track, governed by the withholding rules built into that particular support statute, rather than by Section 12-803's 15%-or-45-times-minimum-wage cap or the rest of Part 8's procedure. Part 8 remains the general wage deduction framework for ordinary money judgments; the support-related statutes listed here handle income withholding for child support and spousal maintenance in their own right.
