Arizona Income Withholding For Support is a procedure required by the Arizona Department of Child Support Services when an individual is ordered to pay child support. This procedure involves the employer of the individual required to pay child support to deduct a certain amount of money from the individual’s paycheck, which is then sent to the Arizona Department of Child Support Services. This money is then distributed to the custodial parent or legal guardian on behalf of the child or children. There are two types of Arizona Income Withholding For Support: Non-IV-D and IV-D. Non-IV-D Income Withholding for Support is used for individuals who are not involved in a court-ordered child support case. IV-D Income Withholding for Support is used for individuals who are involved in a court-ordered child support case.
