(750 ILCS 28/20)
    Sec. 20. Entry of order for support containing income withholding provisions; income withholding notice.
    (a) In addition to any content required under other laws, every order for support entered on or after July 1, 1997, shall:
        (1) Require an income withholding notice to be
    
prepared and served immediately upon any payor of the obligor by the obligee or public office, unless a written agreement is reached between and signed by both parties providing for an alternative arrangement, approved and entered into the record by the court, which ensures payment of support. In that case, the order for support shall provide that an income withholding notice is to be prepared and served only if the obligor becomes delinquent in paying the order for support; and
        (2) Contain a dollar amount to be paid until payment
    
in full of any delinquency that accrues after entry of the order for support. The amount for payment of delinquency shall not be less than 20% of the total of the current support amount and the amount to be paid periodically for payment of any arrearage stated in the order for support; and
        (3) Include the obligor's Social Security Number,
    
which the obligor shall disclose to the court. If the obligor is not a United States citizen, the obligor shall disclose to the court, and the court shall include in the order for support, the obligor's alien registration number, passport number, and home country's social security or national health number, if applicable.
    (b) At the time the order for support is entered, the Clerk of the Circuit Court shall provide a copy of the order to the obligor and shall make copies available to the obligee and public office.
    (c) The income withholding notice shall:
        (1) be in the standard format prescribed by the
    
federal Department of Health and Human Services; and
        (1.1) state the date of entry of the order for
    
support upon which the income withholding notice is based; and
        (2) direct any payor to withhold the dollar amount
    
required for current support under the order for support; and
        (3) direct any payor to withhold the dollar amount
    
required to be paid periodically under the order for support for payment of the amount of any arrearage stated in the order for support; and
        (4) direct any payor or labor union or trade union to
    
enroll a child as a beneficiary of a health insurance plan and withhold or cause to be withheld, if applicable, any required premiums; and
        (5) state the amount of the payor income withholding
    
fee specified under this Section; and
        (6) state that the amount actually withheld from the
    
obligor's income for support and other purposes, including the payor withholding fee specified under this Section, may not be in excess of the maximum amount permitted under the federal Consumer Credit Protection Act; and
        (7) in bold face type, the size of which equals the
    
largest type on the notice, state the duties of the payor and the fines and penalties for failure to withhold and pay over income and for discharging, disciplining, refusing to hire, or otherwise penalizing the obligor because of the duty to withhold and pay over income under this Section; and
        (8) state the rights, remedies, and duties of the
    
obligor under this Section; and
        (9) include the Social Security number of the
    
obligor; and
        (10) (blank); and
        (11) contain the signature of the obligee or the
    
printed name and telephone number of the authorized representative of the public office, except that the failure to contain the signature of the obligee or the printed name and telephone number of the authorized representative of the public office shall not affect the validity of the income withholding notice; and
        (12) direct any payor to pay over amounts withheld
    
for payment of support to the State Disbursement Unit.
    (d) The accrual of a delinquency as a condition for service of an income withholding notice, under the exception to immediate withholding in subsection (a) of this Section, shall apply only to the initial service of an income withholding notice on a payor of the obligor.
    (e) Notwithstanding the exception to immediate withholding contained in subsection (a) of this Section, if the court finds at the time of any hearing that an arrearage has accrued, the court shall order immediate service of an income withholding notice upon the payor.
    (f) If the order for support, under the exception to immediate withholding contained in subsection (a) of this Section, provides that an income withholding notice is to be prepared and served only if the obligor becomes delinquent in paying the order for support, the obligor may execute a written waiver of that condition and request immediate service on the payor.
    (g) The obligee or public office may serve the income withholding notice on the payor or its superintendent, manager, or other agent by ordinary mail or certified mail return receipt requested, by facsimile transmission or other electronic means, by personal delivery, or by any method provided by law for service of a summons. At the time of service on the payor and as notice that withholding has commenced, the obligee or public office shall serve a copy of the income withholding notice on the obligor by ordinary mail addressed to his or her last known address. A copy of an income withholding notice and proof of service shall be filed with the Clerk of the Circuit Court only when necessary in connection with a petition to contest, modify, suspend, terminate, or correct an income withholding notice, an action to enforce income withholding against a payor, or the resolution of other disputes involving an income withholding notice. The changes made to this subsection by this amendatory Act of the 96th General Assembly apply on and after September 1, 2009.
    (h) At any time after the initial service of an income withholding notice, any other payor of the obligor may be served with the same income withholding notice without further notice to the obligor. A copy of the income withholding notice together with a proof of service on the other payor shall be filed with the Clerk of the Circuit Court.
    (i) New service of an income withholding notice is not required in order to resume withholding of income in the case of an obligor with respect to whom an income withholding notice was previously served on the payor if withholding of income was terminated because of an interruption in the obligor's employment of less than 180 days.
