A writ of fi fa or warrant of execution is valid for execution for a period of 12 months from the date of issue (CPR Sched 1 RSC Ord 46, r 8(1); CPR Sched 2 CCR Ord 26, r 6(1)).

If the writ or warrant is not wholly executed it may be renewed for further periods of up to 12 months by application to the court. An application to renew the writ or warrant should be made before the expiration of the original 12-month period of validity or any renewed period (if a further extension is required). However, the court does have the power to grant an extension of its validity even outside that period (CPR Sched 1 RSC Ord 46, r 8(2); CPR Sched 2 CCR Ord 26, r 6(1)).
