825.9. No application relating to child support may be heard unless it is accompanied by the form prescribed for the determination of child support payments, duly completed by the plaintiff, and by the prescribed documents.
Likewise, no contestation of the application may be heard unless the prescribed form has been produced with the prescribed documents by the defendant. The court may, however, relieve the defendant from his default on the conditions it determines.
The rules provided in this article do not apply to a plaintiff or defendant who is not a parent of the child.
