In In re Dickinson, 829 S.W.2d 919, 921 (Tex. App.--Amarillo 1992, orig. proceeding), because the appellant failed to file her enforcement motion within the statutorily prescribed period, that is, within six months of the child becoming an adult, as provided in former family code section 14.40(b) (currently section 157.005(a)), the court of appeals concluded that the trial court lacked jurisdiction to enforce the child support order by contempt. See id. at 922. The court expressed concern that a court should not be able to extend contempt jurisdiction beyond six months after the child becomes an adult by ordering periodic payments beyond that time. See Dickinson, 829 S.W.2d at 921-22.
