The defendant’s name should be set out in full on the acknowledgment of service.


Where the defendant’s name has been incorrectly set out in the claim form, it should be correctly set out on the acknowledgment of service followed by the words ‘described as’ and the incorrect name.


If two or more defendants to a claim acknowledge service of a claim through the same legal representative at the same time, only one acknowledgment of service need be used.


An acknowledgment of service may be amended or withdrawn only with the permission of the court.


An application for permission under paragraph 5.4 must be made in accordance with Part 23 and supported by evidence.
