When Should You Instruct a Costs Lawyer?
Contact Us Today
In many law firms, legal costs are still treated as something to be addressed at the end of a case. A Bill of Costs is prepared, Points of Dispute are dealt with, and, if necessary, the matter proceeds to detailed assessment. While that approach may once have been sufficient, it is increasingly difficult to justify in modern litigation.
Costs are now central to risk, strategy, and overall profitability. Against that background, the question is not simply whether to instruct a costs lawyer, but at what stage their involvement will make the greatest difference.
What does a costs lawyer do?
A costs lawyer is a regulated legal professional specialising in all matters relating to costs. Their role extends well beyond preparing a Bill of Costs and includes advising on recoverability, proportionality, and the presentation of costs claims throughout the life of a case.
In practice, this involves analysing the costs claimed, drafting Points of Dispute and Replies, and assisting with negotiations between the receiving and paying party. In more complex matters, a costs lawyer may also advise on litigation strategy where costs exposure is a significant factor.
Costs lawyers are regulated by the Costs Lawyer Standards Board (CLSB). The CLSB regulates costs lawyers in England and Wales under the Legal Services Act 2007. As a result, they are subject to a formal code of conduct and must undertake continuous professional development. Many are also members of the Association of Costs Lawyers (costs lawyers ACL), reflecting a recognised standard of expertise within the profession.
Why timing matters in costs recovery
The timing of when a costs lawyer is brought into a matter can have a direct impact on the level of costs ultimately recovered.
In many cases, a costs draftsman is only instructed once the litigation has concluded. By that stage, the structure of the costs has already been determined. Time has been recorded in a particular way, work has been carried out at a certain level of seniority, and the overall shape of the claim is fixed.
At that point, the focus is often on defending what has already been done, rather than shaping the outcome. Earlier involvement allows for a more proactive approach, ensuring that the way work is undertaken aligns with how costs will later be assessed.
At the outset: retainers and funding arrangements
One of the most effective stages to involve a costs lawyer is at the beginning of a matter. This is particularly important where funding arrangements are complex or where the financial exposure is significant.
Advice at this stage often centres on advising on retainers and fee arrangements between clients and their legal advisors. The structure of the retainer can have a direct impact on recoverability, particularly if it is later scrutinised.
This is especially relevant in cases involving conditional fee agreements or public funding legal aid. Legal aid costs operate within a specific framework, and errors made at the outset can be difficult to correct later.
A properly structured retainer provides a solid foundation for costs recovery. Without that clarity, issues are more likely to arise at a later stage.
Managing costs during the life of a case
Costs develop alongside the litigation. They are shaped by the decisions made by fee earners, the complexity of the issues, and the conduct of the parties.
Involving a costs lawyer during the course of a case allows those factors to be managed more effectively. This may include advising on proportionality, identifying areas where costs may be vulnerable to challenge, and ensuring that work is carried out at an appropriate level.
In high-value or complex matters, these considerations become particularly important. Small decisions, such as who undertakes a task or how work is recorded, can have a significant impact when costs are assessed.
Preparing a Bill of Costs
The preparation of a Bill of Costs remains a key stage in the process and is often the point at which firms first consider specialist input.
A Bill of Costs is not simply a record of work undertaken. It must present the case in a structured and defensible way, explaining how the litigation progressed and why the costs claimed are justified.
Where this is not done effectively, the claim becomes more vulnerable. This can lead to prolonged disputes, reduced recovery, and increased pressure at detailed assessment.
Specialist input at this stage can make a material difference, both in terms of how the costs are presented and how they are ultimately received.
Responding to Points of Dispute
Once Points of Dispute are served, the matter moves into a more technical phase.
Drafting effective Replies requires a clear understanding of how a costs judge is likely to approach the issues. It is not enough to simply reject the points raised. The response must engage with the substance of the challenge and address it in a structured and reasoned way.
This is often the stage at which the strength of a costs claim becomes clear. Poorly drafted Replies can undermine the position and make resolution more difficult.
Preparing for detailed assessment
Where a dispute cannot be resolved through negotiation, the matter may proceed to detailed assessment.
This is a specialist process where the court will consider the costs claimed in detail. Preparation is critical. The claim must be presented in a way that is clear, consistent, and supported by the evidence.
Issues such as proportionality, the level of fee earner involvement, and the necessity of the work undertaken will all be examined. The approach taken at this stage can have a direct impact on the level of recovery achieved.
Experience across different areas of costs
Costs issues arise across a wide range of practice areas. While personal injury is often associated with costs disputes, similar issues arise in clinical negligence, commercial litigation, Court of Protection work, and matters involving public funding.
A costs lawyer’s experience across these different areas of costs allows them to identify common patterns in how costs are challenged and assessed. This insight can then be applied to individual cases, providing a more informed and strategic approach.
