(a) If the department has reason to believe that a person responsible for the care, custody, or welfare of the child may remove the child from the state before the investigation is completed, the department may file an application for a temporary restraining order in a district court without regard to continuing jurisdiction of the child as provided in Chapter 155.
(b) The court may render a temporary restraining order prohibiting the person from removing the child from the state pending completion of the investigation if the court:
(1) finds that the department has probable cause to conduct the investigation; and
(2) has reason to believe that the person may remove the child from the state.
