What Counts as Professional Negligence in Victoria? The Line Between a Poor Outcome and a Claim

What professional negligence is

Professional negligence arises when a person engaged for their skill and judgement does work that falls below the standard a careful professional in their field would have met, and a client suffers loss as a result. The relationship at the centre of it is one of reliance. The client lacks the technical knowledge the professional holds, engages the professional precisely for that reason, and acts on the advice or the work. When that reliance is misplaced because the professional was careless, the law allows the client to recover the loss that flows from the carelessness.

That reliance is what separates these claims from ordinary commercial disappointment. A client who instructs an accountant to structure a transaction, or a valuer to certify the worth of a property, is not in a position to check the work themselves. They take it on trust. The professional, in accepting the engagement, accepts a duty to bring reasonable care and competence to it. Negligence is the breach of that duty, not the existence of a bad outcome.

The principle reaches across the professions. Legal practitioners, accountants and tax advisers, financial advisers and planners, valuers and surveyors, engineers, conveyancers and insurance brokers all hold themselves out as having skill the client does not. The way carelessness shows up differs from one field to the next, but the underlying idea is constant. The question is always whether the professional did what a reasonably competent practitioner in their position should have done with the same information at the same time.

The four elements of a claim

A professional negligence claim sits in the law of negligence, and frequently also in contract where the work was done under a retainer or engagement. To succeed, a claimant generally has to establish four things. They are proved separately, and a claim can fail on any one of them even where the others are made out.

Duty of care

The first element is a duty of care. A professional who accepts an engagement owes a duty to take reasonable care in carrying it out. In most adviser relationships the duty is uncontroversial, because the professional has agreed to provide a service and the client has relied on it. The harder questions usually concern the reach of the duty rather than its existence: who exactly was owed the duty, and how far it extended. A duty owed to the client who engaged the professional may, in some circumstances, also be owed to a third party who the professional knew would rely on the work.

Breach of the required standard

The second element is breach. The duty is breached where the professional fails to meet the standard their field required. The standard is not perfection, and it is not measured against the ideal practitioner. It is the standard of a reasonably competent professional exercising ordinary skill in that field, assessed against responsible practice among peers. Establishing breach is where most professional negligence claims are won or lost, and it almost always calls for independent expert evidence from a practitioner in the same field.

Causation

The third element is causation. It is not enough that the professional was careless. The breach must have caused the loss, in the sense that the loss would not have been suffered but for the failure, and the loss must not be too remote a consequence of it. Causation is a frequent battleground, because a defendant will often argue that the loss would have occurred anyway, or that some later event broke the chain between the breach and the harm. The claimant has to show that the careless conduct made the difference.

Recognised loss

The fourth element is loss the law will compensate. Breach without loss recovers nothing. Most professional negligence claims concern financial loss, and the measure is generally the difference between the position the client is in and the position they would have held had the work been done with reasonable care, together with consequential losses that are not too remote. The loss has to be a kind the law recognises, and it has to be proved, usually with its own evidence rather than assertion.

The standard of care

The standard a professional had to meet is the heart of most of these claims, and in Victoria it is framed by section 59 of the Wrongs Act 1958 (Vic). Under that section, a professional is not negligent if they acted in a way that, at the time, was widely accepted in Australia by a significant number of respected practitioners in the field as competent professional practice, unless the court considers that opinion unreasonable. This is the peer professional opinion standard, and it has a practical consequence that shapes how a claim is built.

The consequence is that expert evidence usually decides the case. Where a respected body of opinion in the field would have done what the professional did, the claim is difficult, because the conduct sat within accepted practice. Where no careful practitioner would have done so, the breach is established. The contest is therefore less about the facts, which the file records, than about whether the professional's conduct fell within the range a careful professional could reasonably have adopted.

It follows that an honest difference of professional opinion is not negligence. Many decisions a professional makes involve a reasonable choice between accepted approaches, and choosing one over another, even with hindsight an unfortunate one, does not breach the standard. The law does not penalise a careful practitioner for a judgement that a respected body of opinion would also have made. This is why a poor outcome, standing alone, tells you very little about whether a claim exists.

One limit on the peer professional opinion standard is worth understanding. It governs the assessment of whether a professional met the standard of competent practice in carrying out the work. It does not extend to a professional's duty to warn of risk, which the Act treats separately. In other words, the protection that responsible peer practice gives a professional on questions of competent conduct does not automatically answer a complaint that the professional failed to warn the client of a risk they should have been told about.

A poor outcome is not the same as negligence

The clearest way to see the line is through the difference between the result and the conduct that produced it. Consider, without identifying anyone, how this plays out across the fields we act in. The point of each is the same: the outcome alone does not tell you which side of the line you are on.

A lawyer. A litigation strategy that was reasonable on the information available can still lose at trial. A case can turn on a witness who gives evidence no one could have predicted. That is a poor outcome, not negligence. By contrast, a solicitor who lets a clear limitation deadline pass without issuing proceedings, extinguishing an otherwise sound claim, has fallen below the standard regardless of how the case might have gone.

An accountant. A structure that was sensible when it was advised can be undone by a later change in circumstances or in the law that no careful practitioner foresaw. That is commercial risk. An accountant who misreads a plain provision and exposes a client to a liability that competent advice would have avoided has breached the standard, and the loss is often quantifiable to the dollar.

A valuer. A valuation that sat within the range a careful valuer could reasonably have reached at the time is not negligent merely because the market later moved against it. The standard is tested against the range a competent valuer could have reached on the day, not against hindsight. A figure that no competent valuer could have arrived at, which a lender then relied on, is a different matter.

A financial adviser. An investment that performs badly is not, without more, evidence of negligence, because risk is inherent in the engagement. An adviser who recommends a product plainly unsuited to the client's circumstances, or who fails to warn of a risk the client should have understood, has fallen below the standard. Where the advice was also misleading, the conduct may engage the prohibition on misleading or deceptive conduct in section 18 of the Australian Consumer Law, in addition to the law of negligence.

Concurrent duties and the scope of the duty

Two further points shape how a claim is framed, and both can affect whether a claim succeeds. The first concerns where the duty comes from. A professional engaged under a retainer or engagement generally owes duties in both contract and tort at the same time (Astley v Austrust Ltd [1999] HCA 6; (1999) 197 CLR 1). The two sets of duties can run in parallel, and the existence of a contract does not displace the duty of care in negligence. Which cause of action is relied on, or whether both are, can matter to questions such as when the cause of action accrued and how any contributory conduct is treated.

The second point concerns how far the duty reaches. The engagement letter, the terms of business and any scope document define what the professional agreed to do, and they mark the boundary of the duty. A great deal of a negligence matter is decided by what the professional was actually engaged to address, and what fell outside it. That said, the scope of a professional's duty is not always confined to the strict letter of the instructions. It can extend further where a real and foreseeable risk of loss arises that the professional ought to have addressed (Hawkins v Clayton (1988) 164 CLR 539).

The practical lesson is that the scope of the duty is rarely as narrow as a defendant would like, nor as wide as a disappointed client might hope. It is read against the engagement, the surrounding circumstances, and what a careful professional in that position should have recognised. Establishing the reach of the duty is part of building the claim, and it is one of the questions an early review is designed to answer.

How to tell if you may have a claim

Because the four elements are proved separately, the question of whether you have a claim is really four questions, and they are answered from the record rather than from recollection. Was a duty owed, and how far did it reach. Did the work fall below what a careful professional should have done. Did that failure cause the loss, or would the loss have happened anyway. Is the loss one the law will compensate, and can it be measured. A strong claim answers all four. A weak one usually founders on causation or on the standard.

The material that answers these questions is the engagement, the advice or work actually provided, and the file and correspondence, including any attendance notes and any warnings given or not given. Contemporaneous records made close to the events carry more weight than later reconstruction, which is one reason preserving the file early matters. On top of the documents sits independent expert evidence on what a careful professional should have done. These claims are assessed on the file and the expert view, not on assertion.

There is one further reason not to wait. Time limits are strict, and the limitation clock can start before the loss is obvious. The detail of how the period runs, and when it begins, is the subject of our companion insight on time limits, but the practical message is simple. An early and honest assessment protects your position while the options are still open, and it tells you plainly whether a poor outcome is a claim worth bringing or a commercial loss that has to be borne.

This article provides general information about the law in Victoria as at the date of publication. It is not legal advice. Whether a particular professional was negligent, the standard that applied to them, when any limitation period began, and how responsibility should be divided, all turn on the facts of the matter and the evidence available.
