In Mazur v Charles Russell Speechlys LLP [2025] EWHC 2341 (KB) (Mazur), the High Court considered whether a ‘non-authorised person’ is entitled to conduct litigation. It ultimately decided that they couldn’t by virtue of the provisions in the Legal Services Act 2007 (LSA) which reserves this activity for solicitors and a limited number of other authorised professions.
It’s important to note that Mazur hasn’t changed the legal position which remains governed by statute. It has, however, brought several questions to light and the implications for registered providers of social housing (RPs) are potentially significant as many have non-authorised persons (such as paralegals) within their legal teams.
Here, housing litigation expert Josephine Morton explores the implications of Mazur, its unanswered questions and what to watch out for as the appeal progresses.
There are still some unanswered questions for RPs.
In particular:
Permission has been granted for CILEX — the representative body for CILEX Lawyers, Chartered Legal Executives, paralegals and other members of the legal profession — to appeal Mazur, with the Court of Appeal listing a hearing for 24 February 2026 for submissions. Judgment will likely follow at some point after that. It’s also of note that the Law Society has intervened to be part of the appeal. CILEX will argue that Mazur was wrongly decided and has created too much uncertainty in the legal services sector.
Those affected may wish to review their processes now and keep an eye on the upcoming judgment.
With uncertainty likely to continue until the appeal is resolved, many providers will be taking the opportunity to review their internal processes. Our housing and communities team has extensive experience advising RPs on litigation, governance and compliance and can help you to prepare for the potential outcomes.
