A court exercising juvenile jurisdiction shall have exclusive original jurisdiction as set forth in La. Child. Code art. 302, et seq.
Juvenile courts have concurrent subject matter jurisdiction with courts of general jurisdiction over certain issues, including child custody, child support, and certain enumerated adult crimes. The nature of the proceeding involving that subject matter, not the subject matter itself, is determinative of which court properly exercises jurisdiction in accordance with Title III of the Louisiana Children's Code.
La. Dist. Ct. 40.2
Comment
Matters over which courts may have concurrent jurisdiction include the commission of certain criminal acts by minors [(La. Child. Code art. 303(1)), domestic abuse assistance proceedings (La. Child. Code art. 303(9)), custody matters (La. Child. Code arts. 309, 310), child support (La. Child. Code art. 311), and certain criminal proceedings involving children (La. Child. Code art. 312)].
