(a) Real party in interest. Every action shall be prosecuted in the name of the real party in interest. No action shall be dismissed on the ground that it is not prosecuted in the name of the real party in interest until a reasonable time has been allowed after objection for ratification of commencement of the action by, or joinder or substitution of, the real party in interest; and such ratification, joinder, or substitution shall have the same effect as if the action had been commenced in the name of the real party in interest. (b) Reserved. (c) Minors or incompetent persons. The court may appoint a guardian ad litem for a minor or incompetent person not otherwise represented in an action or shall make such other order as it deems proper for the protection of the minor or incompetent person. (d) Unidentified defendant. (1) When it shall be necessary or proper to make a person a party defendant and the party desiring the inclusion of the person as a party defendant has been unable to ascertain the entire name of the defendant or a part of the defendant’s name to ascertain the defendant’s identity, the party desiring the inclusion of the person as a party defendant shall in accordance with the criteria of Rule 11 of these rules set forth in a pleading the person’s interest in the action, so much of the defendant’s name as is known (and if unknown, a fictitious name shall be used), and shall set forth with specificity all actions already undertaken in a diligent and good-faith effort to ascertain the person’s full name and identity. (2) Subject to HRS section 657-22, the person intended shall thereupon be considered a party defendant to the action, as having notice of the institution of the action against that person, and as sufficiently described for all purposes, including services of process, and the action shall proceed against that person. (3) Any party may, by motion for certification, make the name or identity of the party defendant known to the court within a reasonable time after the moving party knew or should have known the name or identity of the party defendant. The motion shall be supported by affidavit or declaration setting forth all facts substantiating the movant’s claim that the naming or identification has been made with due diligence. When the naming or identification is made by a plaintiff, it shall be made prior to the filing of the position statement by that plaintiff, or within such additional time as the court may allow. The court shall freely grant reasonable extensions of the time in which to name or identify the party defendant to any party exercising due diligence in attempting to ascertain the party defendant’s name or identity.(4) When a party defendant has been named or identified in accordance with this rule, the court shall so certify and may make any order that justice requires to protect any party from undue burden and expense in any further proceedings involving the party defendant. (5) A party defendant who has been named or identified in accordance with this rule may have dismissal of one or more claims against the party defendant if the party defendant shows in a timely manner that the delay in naming or identifying the party defendant has caused the party defendant substantial prejudice and if the interests of justice so require.
