When an unemancipated minor above the age of fifteen possesses less than two-thirds of the intellectual or adaptive functioning of a person of the same age with average intellectual or adaptive functioning, evidenced by standard testing procedures administered by competent persons or other relevant evidence acceptable to the court, the parents of the minor, or the person entitled to custody or tutorship of the minor if one or both parents are dead, incapacitated, or absent persons or if the parents are judicially separated or divorced or have never been married to each other, may, with the written concurrence of the coroner of the parish of the minor's domicile, petition the court of that district to place the minor under a full or limited continuing tutorship that shall not automatically end at any age but shall continue until revoked by the court of domicile. The petitioner shall not bear the coroner's costs or fees associated with securing the coroner's concurrence.
