If after the death of a claimant or defendant in any claim the cause of action survives, but no order F2... is made substituting as claimant any person in whom the cause of claim vests or, as the case may be, the personal representatives of the deceased defendant, the defendant or, as the case may be, those representatives may apply to the Court for an order that unless the claim is proceeded with within such time as may be specified in the order the claim shall be struck out as against the claimant or defendant, as the case may be, who has died; but where it is the claimant who has died, the Court shall not make an order under this rule unless satisfied that due notice of the application has been given to the personal representatives (if any) of the deceased claimant and to any other interested persons who, in the opinion of the Court, should be notified.

At any stage in a claim to which this rule applies, the Court may, on the application of any party or of its own motion, direct that notice of the claim be served on any person who is not a party thereto but who will or may be affected by any judgment given therein.

An application under this rule may be made without notice being served on any other party and shall be supported by a witness statement or affidavit stating the grounds of the application.

Every notice of a claim under this rule shall be in Form No. 52 in the relevant Practice Direction and shall be issued out of the appropriate office, and the copy to be served shall be a sealed copy accompanied by a copy of the claim form and of all other statements of case served in the claim and by a form of acknowledgment of service with such modifications as may be appropriate.

A person may, within 14 days of service on him of a notice under this rule, acknowledge service of the claim form and shall thereupon become a party to the claim, but in default of such acknowledgment and subject to paragraph (5) he shall be bound by any judgment given in the claim as if he was a party thereto.

If at any time after service of such notice on any person the claim form is amended so as substantially to alter the relief claimed, the Court may direct that the judgment shall not bind such person unless a further notice together with a copy of the amended claim form is issued and served upon him under this rule.

CPR rule 7.2(2) shall apply in relation to a notice of a claim under this rule as if the notice were a claim form and the person by whom the notice is issued were the claimant.

Any proceedings, including proceedings to enforce a security by foreclosure or otherwise, may be brought by or against trustees, executors or administrators in their capacity as such without joining any of the persons having a beneficial interest in the trust or estate, as the case may be; and any judgment or order given or made in those proceedings shall be binding on those persons unless the Court in the same or other proceedings otherwise orders on the ground that the trustees, executors or administrators, as the case may be, could not or did not in fact represent the interests of those persons in the first—mentioned proceedings.

Paragraph (1) is without prejudice to the power of the Court to order any person having such an interest as aforesaid to be made a party to the proceedings or to make an order under rule 13.
