The complaint in a collections case must be served on all named defendants, and proofs of service on those defendants must be filed, or the plaintiff must obtain an order for publication of the summons, within 180 days after the filing of the complaint.
If proofs of service on all defendants are not filed or the plaintiff has not obtained an order for publication of the summons within 180 days after the filing of the complaint, the court may issue an order to show cause why reasonable monetary sanctions should not be imposed. If proofs of service on all defendants are filed or an order for publication of the summons is filed at least 10 court days before the order to show cause hearing, the court must continue the hearing to 360 days after the filing of the complaint.
If proofs of service of the complaint are filed or service by publication is made and defendants do not file responsive pleadings, the plaintiff must obtain a default judgment within 360 days after the filing of the complaint. If the plaintiff has not obtained a default judgment by that time, the court must issue an order to show cause why reasonable monetary sanctions should not be imposed. The order to show cause must be vacated if the plaintiff obtains a default judgment at least 10 court days before the order to show cause hearing.
