Unless the court directs otherwise, the receiving party must file with the court the papers in support of the bill not less than seven days before the date of a detailed assessment hearing and not more than 14 days before that date.
The Part 47 Practice Direction (para 13.12) gives further details about “the papers in support of the bill”. In respect of each item of costs claimed in the bill the papers in support include all of the papers relevant to that item, whether they are favourable to the receiving party’s case or unfavourable, or whether or not they are confidential or privileged. The lodging of documents as required by the Practice Direction does not amount to a waiver of any privilege in those documents.
