In any action, irrespective of the amount in controversy, other than an action governed by R. 4:4-5 (affecting specific property or a res), if the defendant's true name is unknown to the plaintiff, process may issue against the defendant under a fictitious name, stating it to be fictitious and adding an appropriate description sufficient for identification. Plaintiff shall on motion, prior to judgment, amend the complaint to state defendant's true name, such motion to be accompanied by an affidavit stating the manner in which that information was obtained. If, however, defendant acknowledges his or her true name by written appearance or orally in open court, the complaint may be amended without notice and affidavit. No final judgment shall be entered against a person designated by a fictitious name.
