Before a party files a motion to continue, the party should try to obtain the consent of all other parties in interest. If the parties stipulate to a continuance, they must immediately notify the courtroom department. If all parties do not stipulate, a party may file a motion to continue, which must be served on all previously noticed parties before the day set for the hearing. The motion must state the reason for the continuance, whether a continuance was previously granted, and whether any other party opposes it. If a continuance is granted, the movant must immediately inform all parties expected to appear at the hearing. No continuance, even if stipulated, is effective unless the court announces it in open court or approves it in an order, or the courtroom department informs the parties the judge authorized it.
