Overview
Few professional relationships generate stronger expectations than the relationship between a lawyer and a client.
When a dispute arises, clients often turn to lawyers at moments of considerable financial, commercial, or personal importance. It is therefore understandable that many clients measure the quality of legal services by a simple question: did we win or lose?
The law, however, approaches the matter differently.
A lawyer is generally not engaged to guarantee success. Litigation involves variables that are often beyond the lawyer’s control, including disputed facts, witness credibility, documentary evidence, expert findings, judicial discretion, and the conduct of the opposing party. For that reason, the lawyer’s professional obligation is ordinarily one of care, competence, diligence and sound professional judgment, rather than a guarantee of a particular outcome.
A significant judgment of the Dubai Court of Cassation provides a useful illustration of this distinction. The Court, in Civil Appeal No. 477 of 2025 dated 16 October 2025, examined a professional negligence claim brought against lawyers by a former client and, in doing so, revisited an important question: when does an unsuccessful legal strategy remain within the boundaries of professional judgment, and when does it become actionable professional negligence?
The judgment offers valuable guidance not only for lawyers but also for clients seeking to understand what they are entitled to expect from their legal advisers.
What does a lawyer actually owe a client?
One of the most persistent misconceptions in legal practice is the assumption that a lawyer implicitly promises success.
That assumption is neither commercially realistic nor legally sustainable.
A lawyer is retained to provide legal expertise, professional judgment and diligent representation. The lawyer must understand the facts, identify the relevant legal issues, advise on available options, assess risks, prepare the case properly and take the procedural steps necessary to advance the client’s interests.
What the lawyer cannot promise, however, is the outcome.
A competent lawyer may lose a strong case. Equally, a weak case may occasionally succeed. Courts determine disputes on the basis of evidence and law, not optimism or effort alone.
This principle lies at the center of the Cassation Court’s reasoning. The Court reaffirmed that the lawyer’s role is not to guarantee victory. Professional liability arises not because the client loses, but because the lawyer fails to exercise the level of care expected from a reasonably competent member of the profession.
That distinction is critical. If lawyers were judged solely by outcomes, professional liability would become virtually unlimited. Every unsuccessful litigant would have a potential claim against their former counsel.
The law has wisely rejected such an approach.
Professional judgment deserves protection
The administration of justice requires lawyers to exercise judgment.
Every litigation matter involves strategic decisions. Lawyers decide which claims to pursue, which arguments to advance, which witnesses to call, what evidence to emphasize and how best to present the case.
Reasonable lawyers may disagree on many of those questions.
The fact that a court ultimately rejects a legal argument does not mean that it was unreasonable to advance it. Nor does it mean that the lawyer was negligent.
Professional negligence should not become a vehicle for challenging every strategic decision that, with the benefit of hindsight, could have been made differently.
The Court of Cassation’s judgment reflects this reality. The Court did not examine whether the lawyers’ strategy ultimately succeeded. Instead, it focused on whether the lawyers had discharged their professional responsibilities to the standard of care required by law – which constitutes a sound approach of the Court.
That is the correct approach.
Courts should be cautious before substituting hindsight for professional judgment. Otherwise, lawyers would be incentivized to avoid difficult or innovative arguments and instead adopt only the safest and most conservative positions.
Such an outcome would serve neither clients nor the development of the law.
Where does professional negligence begin?
The fact that lawyers are not guarantors of success does not diminish their responsibilities.
The lawyer’s obligation may be one of care rather than result, but the required standard of care remains a demanding one.
Clients are entitled to expect that their lawyers will understand the applicable law, identify procedural requirements, preserve rights, meet deadlines, present claims properly, and avoid mistakes that a reasonably competent practitioner should not make.
The distinction is often easier to describe than to apply.
The judgment provides a useful example.
The courts found that the issue was not simply that the underlying claim had failed. Rather, the criticism centered on the manner in which the proceedings had been commenced and pursued. The courts concluded that procedural and professional errors had deprived the client of the opportunity to obtain the relief sought.
Whether one agrees with the factual findings is less important than the broader legal proposition emerging from the judgment: liability arises not because the client failed, but because the lawyer’s conduct itself fell below the required professional standard.
This distinction deserves emphasis.
There is a substantial difference between a lawyer advancing a reasonable argument that is ultimately rejected and a lawyer failing to take steps that should have been taken in the first place.
The former is part of legal practice. The latter may amount to negligence.
The importance of causation
Causation is perhaps the most overlooked aspect of professional negligence claims.
Even where an error is established, liability does not automatically follow.
The claimant must still demonstrate that the error caused the loss complained of.
This requirement serves an important function. Not every mistake has consequences. Some errors are ultimately immaterial. Others occur in cases that would have failed regardless of the lawyer’s conduct.
The Court’s reasoning reinforces this principle. Liability depended not merely on identifying professional fault but on establishing a connection (causation link) between that fault and the damage allegedly suffered.
For practitioners, this remains one of the most important safeguards against speculative professional negligence claims.
For clients, it serves as a reminder that dissatisfaction with the outcome is not enough. The question is whether the outcome would likely have been materially different absent the alleged error.
What clients should reasonably expect
The judgment also invites a broader discussion about client expectations.
Clients are entitled to expect diligence preparation, honesty, candid opinion concerning the risks, competent advice, and careful handling of procedural requirements.
On the other hand, clients should not expect certainty. Lawyers present their legal opinion and advice. However, the ultimate decision is brought forward by the Courts. Similarly, a lawyer may recommend a certain course of action that appears to be conducted correctly in its entirety yet still face an adverse judgment. That is an unavoidable feature of litigation.
The legal profession should not be judged by whether every case succeeds. It should be judged by whether lawyers discharge their responsibilities competently, diligently, and in accordance with the standards expected of the profession.
Closing observations
The Dubai Court of Cassation’s judgment provides a timely reminder of a principle that is sometimes forgotten by both lawyers and clients: A lawyer’s is to exercise professional skill, care, and judgment in the service of the client’s interests.
Where that standard is met, an adverse judgment should not, by itself, generate liability. In the circumstances where such standard is not met, professional accountability should follow.
The distinction may appear simple, but it sits at the heart of every professional negligence claim against a lawyer. The Court’s judgment reinforces that the law continues to recognize and preserve that balance.
