6.5.—(1) If P becomes a party to the proceedings, all documents to be served on P must be served on P's litigation friend or as directed by the court on P's behalf.
(2) The court may make an order for service on P by permitting the document to be served on some person other than the person specified in paragraph (1) (which may include service on P).
(3) An application for an order under paragraph (2) may be made without notice.
(4) The court may order that, although a document has been served on someone other than a person specified in paragraph (1), the document is to be treated as if it had been properly served.
(5) This rule does not apply in relation to the service of documents on P in any case where the court has made an order under rule 17.5(1)(b) (power of court to bring to an end the appointment of a litigation friend).
(Rule 7.3 requires P to be notified where a direction has been made under rule 1.2, and of the appointment of a litigation friend, accredited legal representative or representative.)
