Legal Ombudsman or a negligence claim: which route when your solicitor gets it wrong?

If your solicitor’s mistake has cost you less than £50,000 and the real problem is poor service, the Legal Ombudsman is usually the quicker and cheaper route. If the loss is larger, or may grow, a professional negligence claim in the courts is the better choice, because once you accept an ombudsman’s decision, section 140(11) of the Legal Services Act 2007 stops you suing over the same matter. Neither route pauses the court time limits.

Most people asking this question have just received a firm’s final response to a complaint, often ending with a paragraph explaining how to contact the Legal Ombudsman. Many read that as the next step on the way to court. It is a separate route with its own rules, and choosing it without weighing the size of the loss can close the door on a claim worth far more.

Two routes built for different problems

The Legal Ombudsman exists under Part 6 of the Legal Services Act 2007 to resolve complaints about the service clients receive from lawyers. Section 137(1) requires each complaint to be decided by reference to what is, in the ombudsman’s opinion, “fair and reasonable in all the circumstances of the case”. There is no need to prove negligence: section 137(5) says the power to give directions “is not confined to cases where the complainant may have a cause of action against the respondent for negligence”. Delay and poor communication are its everyday work, and our page on solicitor negligence and challenging your solicitor’s bill looks at the same problems from the claimant’s side.

A negligence claim asks a narrower and harder question. Did the lawyer fall below the standard of a reasonably competent practitioner, and did that failure cause you a loss the law will compensate? A judge decides it, with expert evidence where needed, and there is no ceiling on damages. Our overview of legal negligence claims against solicitors and barristers sets out what has to be proved.

What the Ombudsman can order a firm to do

Section 137(2) gives the ombudsman five kinds of direction. It can require an apology; limit the fees the firm is entitled to and order them refunded or waived; order compensation “in respect of any loss which has been suffered by, or any inconvenience or distress which has been caused to, the complainant”; require the firm to put an error right at its own expense; or direct it to take other action in your interests. Where the firm has already owned up to an error, our guidance on whether your solicitor has to tell you they made a mistake explains what the solicitors’ code requires of it.

An accepted decision has teeth. Section 141(2) makes compensation and fee refunds “recoverable, if a court so orders on the application of the complainant or an ombudsman, as if it were payable under an order of that court”. If the firm has since closed, the Ombudsman’s own guidance says a compensation award would have to be claimed from the firm’s indemnity insurer, and warns that insurers are not obliged to pay a fee refund. Our article on what happens when a solicitor’s firm has closed or collapsed explains how run-off cover responds.

The £50,000 ceiling, and what sits outside it

Section 138(1) provides that the total value of directions under section 137(2)(c) to (e) “must not exceed £50,000”. That figure was substituted with effect from 1 February 2013 by the Legal Services Act 2007 (Alteration of Limit) Order 2012, SI 2012/3091. Many guides date the increase to April 2023, which is when the Ombudsman’s Scheme Rules were last overhauled, but the statutory cap did not move then. A court applies no cap at all, assessing damages on the principles in our guide to how compensation is calculated in a professional negligence claim.

Two things fall outside the ceiling. Section 138(2) counts only compensation and the cost of remedial work, so a direction under section 137(2)(b) limiting your fees and ordering a refund is added on top of the £50,000, and section 138(3) says interest is “to be ignored”. On an overcharged modest matter, that makes the Ombudsman worth more than the headline figure suggests. Where the loss runs to six figures, as it often does in conveyancing negligence claims, the cap decides the question.

Who can complain, and about whom?

Section 128 defines the parties. The lawyer or firm must, at the time of the act complained of, have been “an authorised person in relation to an activity which was a reserved legal activity”, and the words that follow, “whether or not the act or omission relates to a reserved legal activity”, bring a solicitor’s will drafting or general advice within the scheme even though those tasks are not reserved. Barristers are authorised persons too, so the same scheme handles complaints about counsel alongside the court route described in our page on negligent barrister claims. A will writer who is not an authorised lawyer falls outside it altogether, which is why our guide to negligent will writing claims concentrates on the courts.

On the complainant’s side, section 128(3) admits individuals and any other person “of a description prescribed by order”, which reaches some smaller organisations; larger companies will generally need to go to court. Section 128(4)(c) also lets a beneficiary complain about services a lawyer provided as, or to, a personal representative or trustee. That matters where an estate has been mishandled, as our article on probate solicitor errors and delays explains. Public bodies are excluded by section 128(5)(b).

The Ombudsman’s own deadlines

Section 126(1) excludes a complaint unless you have “first used the respondent’s complaints procedures”. The firm then has up to eight weeks to respond. The Ombudsman’s published guidance says you can generally bring a complaint within one year of the problem happening, or one year from when you found out about it, and that you must bring it within six months of the firm’s final response. Those limits come from the Scheme Rules made under the Act, currently the April 2023 version, and outside them the Ombudsman may refuse to investigate. If you go to court instead, a different pre-action process applies, set out in our guide on how to start a professional negligence claim.

The process is slow. The Ombudsman currently says its initial checks can take up to 12 weeks and that most cases take 9 to 12 months to be accepted and for an investigation to begin, with most investigations then completed in 3 to 6 months. A client who complains a year after the mistake may be two years further on before a decision arrives, and that delay counts against any court claim, a point we develop in our page on time-barred compensation in professional negligence claims.

Accepting a decision closes the court route

Under section 140(4), if you tell the ombudsman you accept the determination, “it is binding on the respondent and the complainant and is final”. Section 140(11) then provides that neither side “may institute or continue legal proceedings in respect of a matter which was the subject of a complaint” once the determination has become binding and final. Accept £20,000 for a mistake that later proves to have cost £200,000 and the balance is gone. If you are unsure how large the loss really is, take advice before the acceptance date passes; we look at exactly that question in a fixed fee second opinion.

Rejecting the decision has the opposite effect, and so does staying silent, because section 140(5) treats a complainant who does not respond by the specified time as having rejected it. The determination then binds nobody and the right to sue survives, subject to the Limitation Act. A claim would proceed under the professional negligence pre-action protocol, beginning with a letter of claim of the kind described in our guide to what should be in a letter before claim for professional negligence.

When a negligence claim is the better choice

Court is usually the right route where the financial loss is above, or close to, £50,000. It is also the better forum where the dispute turns on legal analysis and expert evidence rather than on how the file was handled. Lost litigation is the clearest example, because valuing the chance you lost requires the approach explained in our note on Supreme Court guidance on valuing the loss of a litigation chance. The same is true where a solicitor failed to warn you of an obvious risk, a duty examined in our article on solicitors’ duty to warn clients of risks.

A claim also brings tools the Ombudsman does without, such as disclosure of the firm’s internal documents and expert evidence on what a competent solicitor would have done. A judgment is met by the firm’s insurer. Funding needs thought, and if a previous firm’s no win no fee terms are part of the dispute, our article on challenging unclear no win no fee agreements covers that ground.

Disputing the bill: assessment, complaint or claim?

Where the grievance is the size of the bill, there is a third route. Under section 70(1) of the Solicitors Act 1974, if you apply within one month of delivery of the bill, the High Court “shall” order it to be assessed. After that, assessment is discretionary; section 70(3) requires special circumstances once 12 months have passed from delivery or the bill has been paid, and section 70(4) removes the power altogether 12 months after payment. Our guide to solicitor and client costs disputes and detailed assessment explains the procedure.

The Ombudsman’s own guidance says it cannot stop a firm suing you for outstanding fees while your complaint is waiting or under investigation, and cannot insist the firm releases your file while costs are unpaid. If a firm serves a statutory demand for its fees, a genuine dispute about the debt, including a substantial cross-claim in negligence, can be a reason for the court to intervene, and our guidance on setting aside a statutory demand explains the grounds.

Ombudsman, regulator or financial watchdog?

Three bodies are regularly confused in searches. The Legal Ombudsman deals with service. The Solicitors Regulation Authority deals with professional conduct and does not compensate the client for a solicitor’s error. The Financial Ombudsman Service covers financial advisers and brokers, with a different award limit and its own rules, and our page on negligence claims against financial advisers compares it with a court claim.

The other confusion is about who made the mistake. If an accountant or tax adviser let you down, the Legal Ombudsman will usually have no jurisdiction, because section 128(1) reaches only authorised persons and most accountancy practices hold no authorisation for reserved legal activities. The tax position may need rescuing first: our guidance on late appeals against HMRC covers the case where an adviser caused the delay, and our page on negligent tax advice claims deals with suing the adviser. Insolvency practitioners answer to their own regulators, and our page on professional negligence claims against insolvency practitioners and lawyers explains the court route against them.

The court clock keeps running during a complaint

Nothing in the Limitation Act 1980 suspends time while a complaint sits with the firm or the Ombudsman. The primary period is six years from the breach of contract under section 5, or from the date damage occurred in tort under section 2. Where the damage was hidden, section 14A(4)(b) allows three years from the date you had the knowledge required, but section 14B imposes a 15-year longstop from the negligent act. Our guide to the limitation period for a professional negligence claim works through these dates, and our analysis of section 14A and the date of knowledge explains the test.

A complaint can also be used against you on limitation. Section 14A(5) starts the three years from the earliest date you had “both the knowledge required for bringing an action for damages in respect of the relevant damage and a right to bring such an action”, and a detailed complaint letter listing the firm’s errors is good evidence that the date had arrived. If you are in the Ombudsman’s queue and a deadline is within reach, a standstill agreement or protective proceedings may be needed, as our page on limitation periods and standstill agreements explains.
