Texas Family Code - FAM § 65.061. Guardian Ad Litem

(a) If a child appears before the truancy court without a parent or guardian, or it appears to the court that the child's parent or guardian is incapable or unwilling to make decisions in the best interest of the child with respect to proceedings under this chapter, the court may appoint a guardian ad litem to protect the interests of the child in the proceedings.

(b) An attorney for a child may also be the child's guardian ad litem. A law enforcement officer, probation officer, or other employee of the truancy court may not be appointed as a guardian ad litem.

(c) The court may order a child's parent or other person responsible to support the child to reimburse the county or municipality for the cost of the guardian ad litem. The court may issue the order only after determining that the parent or other responsible person has sufficient financial resources to offset the cost of the child's guardian ad litem wholly or partly.
