740 ILCS 170/4.1: Revocation of wage assignment.

If the wage assignment is revocable under federal law, the employee may revoke the wage assignment at any time by submitting the Revocation Notice Form as provided in subsection (c) of Section 2.2 of this Act or otherwise providing written notice of revocation to the creditor. Revocation is effective regardless of how the creditor receives it. Failure to use the sample language provided in the notice described in Section 2.2 does not affect the validity of the written notice of revocation. The employee may submit a copy of the notice to his or her employer. If the written notice of revocation is served upon the creditor prior to the creditor's service of demand upon the employer, the demand shall not be served.
