License suspension is an enforcement remedy that can restrict a delinquent support obligor's professional licenses, recreational licenses, and driver's license for failure to pay child support arrears above specified thresholds.

In Arizona license suspension for child support arrears is administered through the child support enforcement system. When arrears reach the threshold the support enforcement agency can certify the obligor to the relevant licensing authority for suspension.

License suspension is a powerful motivator for payment because it affects a person's ability to work and to drive.
