Every UK solicitor is required by the Solicitors Regulation Authority's Code of Conduct to provide a client care letter (sometimes called an engagement or retainer letter) at the outset of a matter. This is a binding contract for legal services, and it is the single most important document governing the solicitor-client relationship — yet it is routinely signed without scrutiny. The SRA Standards and Regulations require specific disclosures: the basis on which fees are charged, an estimate of overall costs, who will work on the matter and their seniority, the firm's complaints procedure, and details of the firm's regulator. What the letter does not have to disclose, and what causes most problems later, is the scope of the work — what is and is not included. Disputes about whether a piece of work was 'inside' or 'outside' the retainer are among the most common causes of fee complaints to the Legal Ombudsman.
What is a Client Care Letter?
A solicitor's client care letter (or retainer letter) is a written agreement between a solicitor and client that establishes the scope of legal services, the basis of charging, the people performing the work, the firm's complaints process, and the firm's regulatory status. It is required by SRA Code of Conduct for Solicitors, RELs and RFLs, paragraphs 8.6–8.11, and SRA Code of Conduct for Firms, paragraphs 7.1(c). The letter incorporates the firm's terms of business by reference and, once signed, forms a legally binding services contract enforceable in court.
Red flags to watch for
SRA Code paragraph 8.7 requires the solicitor to give the client the best possible information about the likely overall cost of the matter, both at the outset and as the matter progresses. A client care letter that quotes hourly rates without any costs estimate is non-compliant — and Legal Ombudsman decisions have ordered fee reductions for this failure.
If the scope is described as 'general advice on the matter' without specifying inclusions and exclusions, the solicitor can later argue that work you assumed was included was actually 'additional' and chargeable extra. Specific scope language — what is included, what is excluded, what triggers an extension — protects both parties.
Paragraph 8.10 of the SRA Code requires identification of the person dealing with the matter and the person responsible for supervision. If a junior fee earner is doing most of the work but you are charged a partner rate, this is challengeable.
Paragraph 8.3 of the SRA Code requires firms to inform clients of their right to complain, the procedure, and the right to escalate to the Legal Ombudsman. A letter that omits these is non-compliant and gives the client grounds to challenge any subsequent fee dispute.
Solicitors have a common-law and statutory lien (e.g., under the Solicitors Act 1974) over client documents for unpaid fees. The retainer letter often expands this — e.g., to include the right to apply client account funds against bills. The scope of any lien should be specifically reviewed.
Solicitors must give clients reasonable notice before terminating a retainer (Solicitors Act 1974 s 65 and SRA Code para 1.4). A letter giving the firm an unfettered right to terminate at any moment is contrary to professional obligations and may leave the client in difficulty in litigation timeline matters.
Your legal rights
UK solicitor clients are protected by: the Legal Services Act 2007; the Solicitors Act 1974 (particularly s 64–74 on costs and bills); the SRA Standards and Regulations (Code of Conduct for Solicitors, RELs and RFLs, and Code of Conduct for Firms); the Consumer Rights Act 2015 (where the client is a consumer, services must be performed with reasonable care and skill and within a reasonable time); and the right to refer fee disputes to the Legal Ombudsman within six years of the act or omission, or three years of awareness. Bills can be challenged by application for a detailed assessment under Solicitors Act 1974 s 70 within one month of delivery. Misconduct complaints go to the SRA. Negligence claims are pursued in the High Court or County Court.
Questions to ask before you sign
- 1What is your best estimate of the overall costs of this matter, and how often will you update me on costs as the matter progresses?
- 2Precisely what work is included in this retainer — and what is excluded that I might assume is included?
- 3Who will be doing the work day-to-day, what is their rate, and who supervises them?
- 4What is your complaints process, and how do I escalate to the Legal Ombudsman if needed?
- 5What is your termination policy — both yours and mine — and what happens to fees and documents on termination?
- 6Do you take a lien over my documents or money for unpaid fees, and on what specific terms?
