NLJ this week: WhatsApp messages are part of ‘the file’

Digital informality meets hard-edged costs law. In this week's NLJ, David Bailey-Vella, chair of the Association of Costs Lawyers and legal director at Pogust Goodhead, examines MacInnes v DWF Law LLP, in which the Senior Courts Costs Office held that if a firm bills for WhatsApp work, those messages form part of the ‘file’—even if stored on personal devices
