A child support obligation owed to an obligee who is a judgment debtor may not be subject to execution, garnishment, attachment, or other process except to satisfy that child support obligation. This section does not prohibit the child support agency from authorizing the state disbursement unit to apply a payment of past-due support owed to an obligee to a child support obligation owed by the same obligee or to another debt being enforced by the North Dakota department of health and human services that arises out of a public assistance program.
