Sarah Marshall

Legal Costs Negotiator

My career in law began over 19 years ago as a PA in an Insolvency Team. I undertook CiLex Level 3 and became a Paralegal within a Credit Control Team.


I started my costs journey in 2019, dealing with Personal Injury and Clinical Negligence Claims. I deal with high value Bill of Costs and budgeted Bill of Costs. I also have experience of conducting JSMs. I am able to argue the Claimant’s point in a calm but effective manner.


I joined TLS in September 2025.


I have two young boys who keep me active. We enjoy walks, bike rides and football.
