Mazur – its impact on litigation and costs

On 16 September 2025, Mr Justice Sheldon handed down his judgment in Mazur which has since sent shockwaves through the legal profession. The judgment considers whether and to what extent non-authorised fee earners (and their employers) are permitted to carry out legal work within the constraints of The Legal Services Act 2007 (LSA). The Judge’s conclusions seem to indicate that many non-authorised fee earners, and their employers, may be ‘conducting litigation’ without the appropriate LSA authority; an act that can be considered a criminal offence.

Nick McDonnell, Director and Costs Lawyer with Kain Knight, will consider the impact of Mazur on law firms and legal practitioners and specifically its potential impact on costs recovery in litigation.
