Ala. Code § 30-3-64
Within 14 days of the service of an income withholding order upon an employer, the employer shall file an answer with the court which issued the order. The answer shall state whether or not the obligor is employed by the employer and whether the employer has in his or its possession income, as such term is defined in this article, due or due to become due to the obligor. The answer shall also indicate the amount of the obligor's disposable income, as such term is defined in the Federal Consumer Credit Act, and whether the obligor's disposable income is currently subject to any writ of garnishment, previous income withholding order or other legal process and the nature and extent of such previous judgment and process. If the employer answers that the obligor has income which is subject to the order for income withholding the order entered pursuant to any of the provisions of this article shall become binding upon any such employer, including successive employers, 14 days after service pursuant to the Alabama Rules of Civil Procedure, and shall remain effective until further order of the court. Provided, any order for income withholding may be modified or terminated by the court at any time upon a finding by the court of a material and substantial variance in the facts as originally established by the court or due to a change in circumstances which is substantial and continuing and which is otherwise sufficient grounds, under existing and future case law and statutory law, for such modification or termination.
