Section 388 petition (request to change court order): hearing within 30 calendar days of filing

If there is no such stipulation and the petition has not been denied ex parte under section (d), the court must either: (1) order that a hearing on the petition be held within 30 calendar days after the petition is filed; or (2) order a hearing for the parties to argue whether an evidentiary hearing on the petition should be granted or denied. If the court then grants an evidentiary hearing on the petition, that hearing must be held within 30 calendar days after the petition is filed.
