If a noncustodial parent falls behind on child support payments, you do have options for enforcing it, but they must be carried out through the court. The court can use various methods to collect any back child support payments. These methods can include income withholding, wage garnishment, interception of tax refunds, liens or attachments to property. Additionally, a court can take punitive actions if these methods are unsuccessful which include license suspension, passport denial, and even possible jail time.
