Duration and renewal of originating summons for purpose of service
13.—(1)  Subject to the other provisions of these Rules, for the purpose of service, an originating summons is valid in the first instance —
(a)where leave to serve the originating summons out of jurisdiction is required — for 12 months starting on the date of its issue; or
(b)in any other case — for 6 months starting on the date of its issue.
(2)  Subject to paragraph (3), where an originating summons has not been served on a party against whom the application in question is made, the Court may by order extend the validity of the originating summons from time to time for any period (not exceeding 6 months at any one time) that the Court specifies in the order, starting on the day immediately following that on which the originating summons would have expired (called the expiry date), if any application for extension is made to the Court before the expiry date.
(3)  Where the Court is satisfied on an application under paragraph (2) that, despite the making of reasonable efforts, it may not be possible to serve an originating summons within 6 months, the Court may, if it thinks fit, extend the validity of the originating summons for any period (not exceeding 12 months at any one time) that the Court specifies in the order.
(4)  Before an originating summons, the validity of which has been extended under this rule, is served, it must be marked with an official stamp in Form PIR‑1 showing the period from which the validity of the originating summons has been extended.
