Why the model tagged it this way: The bill amends Family Code provisions on child support orders to automatically apply Title IV-D enforcement services (including earnings assignments and payment processing through the State Disbursement Unit) to all orders unless the obligee opts out in non-mandatory cases. This increases obligations and enforcement mechanisms for the paying parent (obligor), consistent with the custody-support axis measuring the paying/less-custodial parent's rights versus obligations. No other listed topics are substantively addressed.
