The cost of a signature: The fallout from Mazur v Charles Russell Speechlys

Episode #4913 November 2025

A single court case has redrawn the line between supporting and conducting litigation. In Mazur v Charles Russell Speechlys, the High Court confirmed that only authorised individuals can conduct litigation, a term that stretches from issuing proceedings to managing related tasks and crucially, supervision by a solicitor does not create authorisation.

Beginner summary

The Legal Services Act 2007 reserves conducting litigation to authorised professionals such as solicitors, barristers, and legal executives. Paralegals and non-authorised staff may support cases but cannot issue claims, file documents, or take key procedural steps. Supervision by a solicitor does not make an unauthorised person authorised. Firms must now review delegation practices to avoid breaching the Act and ensure that only qualified individuals perform reserved tasks.
