Regulation summary

Costs Lawyers are qualified experts in legal costs. They can advise clients on issues like litigation costs, the cost of legal services (such as solicitors’ or barristers’ fees), and legal aid costs. They have a right to appear in court on behalf of their clients on matters relating to costs.

The Costs Lawyer Standards Board, or CLSB, is the regulator of Costs Lawyers in England and Wales. It serves the public interest by setting and maintaining the standards of professional conduct by which Costs Lawyers must abide.

The CLSB is a wholly owned subsidiary of the Association of Costs Lawyers (ACL). ACL is the profession’s representative body and it is named in the Legal Services Act 2007 as the approved regulator of the Costs Lawyer profession. However, as a representative body, it must delegate its regulatory functions to another organisation. It has therefore delegated its regulatory functions to the CLSB.

You might be eligible for exemptions from certain aspects of the Costs Lawyer Qualification if you have completed relevant prior learning, such as a law degree or a professional training course.

In addition to the academic element of your training, you will need to complete a period of supervised practice. This can be carried out before, during or after studying for the Costs Lawyer Qualification.

Summary of routes

Certain qualifications and experience gained outside the UK may be recognised by application under the Recognition of European Professional Qualification Rules. Those Rules govern the process by which the CLSB will consider an application for recognition of an overseas professional qualification as being equivalent to the domestic Costs Lawyer Qualification. If you make a successful application under the Rules, despite not having completed the Costs Lawyer Qualification, you will be entitled to apply for a practising certificate to practise as a Costs Lawyer in England and Wales.
