Claim Against a Solicitor UK: Negligence Claims Guide

Overview

A claim against a solicitor is a legal action alleging that the firm or individual solicitor failed to meet the standard of care expected of a reasonably competent professional, and that this failure caused you loss. It sits under the umbrella of professional negligence and is usually pursued in the civil courts if it cannot be resolved through the firm's complaints process or the Legal Ombudsman.

The legal test generally comes down to three things. First, that the solicitor owed you a duty of care (this is almost always straightforward where you were the client). Second, that they breached that duty by doing something a competent solicitor would not have done, or failing to do something they should have done.

Third, that the breach caused you a measurable loss. Without loss, there is no claim worth bringing, even if the work was poor. Claims can also be brought for breach of contract (the retainer you signed), breach of fiduciary duty, or misconduct reportable to the Solicitors Regulation Authority. These routes can run in parallel or separately, depending on what actually went wrong.

Key steps

1. Gather every document tied to the matter. Pull together your retainer letter, engagement terms, correspondence, invoices, court papers, attendance notes you were sent, and anything else that shows what the solicitor was instructed to do and what actually happened. A clear paper trail is the backbone of any negligence claim, so do this before memories fade. 2. Use the firm's internal complaints procedure first. Every regulated firm must have a written complaints process and must tell you about it. Put your complaint in writing, set out what went wrong, explain the loss you have suffered, and ask for a specific outcome. The firm has up to eight weeks to respond under the rules, and many disputes get resolved at this stage without needing to go further. 3. Escalate to the Legal Ombudsman if the response is unsatisfactory. If the firm rejects your complaint or does not reply within the timeframe, you can refer the matter to the Legal Ombudsman. The Ombudsman deals with service complaints and can order compensation up to a set limit. There are strict time limits for referral, so do not delay once the firm's response lands. 4. Consider a professional negligence claim for larger losses. Where your losses exceed what the Ombudsman can award, or the issue is clearly negligence rather than poor service, a civil claim is the right route. This usually starts with a formal Letter of Claim following the Professional Negligence Pre-Action Protocol, giving the solicitor and their insurer a chance to respond before court proceedings are issued. 5. Watch the limitation period carefully. Most professional negligence claims must be brought within six years of the negligent act, with a possible extension where the damage was not reasonably discoverable at the time. Miss the deadline and your claim will almost certainly be struck out, regardless of how strong the underlying case is. Get specialist input early if time is tight.
