(2) The parent or other person awarded custody of the minor is domiciled, if the parents are divorced or judicially separated; or

(3) The minor resides.

(1) They shall petition jointly for appointment as cotutors in the district court of the parish in which the proceedings for divorce or judicial separation were instituted, or if the award of joint custody has specified the legal domicile of the minor, in the district court of the parish of the legal domicile of the minor, or in the district court of the parish where the child resides.
