The issue is whether an Title IV-D child-support enforcement judge has authority to modify conservatorship.

The issues challenging the trial court's order to withhold wages and split retirement benefits to enforce contractual alimony are (1) whether wages may be withheld under the Texas Family Code chapter 8 to satisfy the alimony agreement and (2) whether Texas Property Code section 42.0021 exempts retirement money from seizure in this case nor whether federal retirement law (ERISA) preempts Texas law.
