Lauren Mackenzie

Senior Solicitor specialising in Dispute Resolution and Mediation

Lauren is an experienced commercial and civil litigator, having trained in the City and worked in London for 8 years. She is an accredited mediator with strong expertise in resolving legal disputes outside of a courtroom.

Lauren moved to Longmores in March 2016 where she handles a range of business and personal legal disputes for clients of all sizes, from multinational corporations to individuals.

She brings to the firm a real breadth of knowledge across many different areas of law, with a lot of experience handling financial services, litigation, energy litigation and banking litigation, as well as dealing with contentious probate matters and general civil litigation.

Lauren takes great satisfaction from getting to know her clients on a deep level, being able to assist them in a way that makes a real impact on their business and personal affairs. She often finds herself acting as a sounding board for her clients, offering sensible, pragmatic solutions that work.

She loves building relationships with clients, developing a mutual respect which allows them to work together effectively. A key part of her job is to offer a reality check about the risks, costs and likely outcomes involved in a particular course of action a client wants to take. Where appropriate, she is frequently able to suggest alternatives that clients haven’t considered which have the potential to save them a lot of time, money and stress.


Having studied English and French at the University of Leeds, Lauren completed the Legal Practice Course in 2005 and started a training contract with a leading London law firm in 2006.

Lauren qualified as a Solicitor in 2008 and has worked at a range of firms and organisations, including the Royal Bank of Scotland Group. She has spent many years working in London, including for a large City law firm and a boutique West End firm. She has also spent time working in Brussels.

  • Breach of contract claims
  • Debt recovery matters
  • Shareholder disputes
