Professional Negligence Lawyers in Melbourne

A professional cost you money. Your clock started the day they got it wrong.

You paid a professional for advice or work, and you relied on it. The advice was wrong, or the work was botched, and now you are out of pocket. Before anything else, pin down the date the mistake was made. Under the Limitation of Actions Act 1958 (Vic) you generally have 6 years from the date of the breach to file, and a strong professional negligence claim becomes worthless the day that window closes.

Call MK Law on 1800 130 120 for a free first conversation. Bring the file number, the date you signed the retainer, and the date you spotted the problem.

A professional negligence claim is won or lost on evidence, not outrage. The professional indemnity insurer behind the other side does not care that you feel let down. It responds to an expert report that proves a competent peer would have done better, and to a number that shows what the failure cost you. Get those two things right and most files settle long before a courtroom.

What professional negligence actually means

Professional negligence occurs when someone who holds themselves out as skilled, a lawyer, an accountant, a financial advisor, a conveyancer, falls below the standard expected of a competent member of their profession, and that failure causes you a measurable financial loss. The law expects a professional to exercise reasonable care and skill in the work they are paid to do. A poor result on its own is not enough. Markets fall, deals collapse, and not every disappointing outcome is someone’s fault. What turns a bad outcome into a claim is a breach of the duty of care that a competent peer would not have made.

That distinction is the whole game. A negligence lawyer spends the first review separating the part of your loss the professional caused from the part the world would have delivered anyway.

The four elements of a professional negligence claim

Every professional negligence claim turns on the same four questions. A weakness on any one of them sinks the file.

Duty of care

The professional accepted you as a client and agreed, expressly or by conduct, to do the work. Duty is rarely the fight. A retainer letter, a tax invoice, or a paper trail of instructions will usually settle it.

Breach of the standard

The professional fell below the standard expected of a competent peer in the same field. That standard of care is set by expert evidence from another practitioner in the same area, not by the judge’s own view. A lawyer is judged against a competent lawyer, an accountant against a competent accountant. The Wrongs Act 1958 (Vic) codifies the test for professionals, and the question is always whether a competent peer acting with reasonable care would have done the same thing.

Causation

The breach actually caused your loss. If the deal would have collapsed anyway, or the tax bill would have arrived regardless, causation falls over. The court asks what would have happened if the professional had done their job properly, and the burden is on you to prove it. This is where many otherwise-strong files come apart, so we test causation hard before we ever issue.

Loss

A real, measurable financial loss in dollars. Out-of-pocket costs, lost opportunity, tax penalties, the difference between what an asset was worth and what you paid for it. If you have suffered loss you cannot put a figure on, there is nothing for a court to award. We quantify the loss with a forensic accountant where the numbers are not obvious.

How we test negligent advice on the first call

Most matters start with one document: the advice letter, the contract, the tax return, the settlement statement that turned out to be wrong. We read it on the first call and work through the four elements with you, duty, breach of duty of care, causation and the loss suffered. By the end of the conversation you have a plain view of whether a competent peer would have acted differently, roughly what the failure cost you, and how much time is left on the 6-year clock. If there is a claim, you also have a clear next step.

Who we act against

We act against the full range of professionals who get paid for advice or work that other people rely on. The legal test does not change between them. What changes is the profession the expert evidence has to come from.

Negligent solicitors and barristers. Missed limitation dates, botched conveyances, dud advice on a settlement, undisclosed conflicts, drafting that fails to do what the client asked for.

Accountants and tax agents. Missed deductions, late lodgements that trigger penalties, structures that collapse under ATO scrutiny, audit failures that let a fraud run for years.

Financial advisors and stockbrokers. Unsuitable product advice, churning, failure to consider your risk profile, breach of the best-interests duty under the Corporations Act. Claims against financial advisors are some of the most common we run, because the loss is usually easy to count.

Conveyancers. Settling without the right searches, missing easements or encumbrances, errors on the transfer that cost the buyer or seller after settlement.

Other professionals. Auditors, insolvency practitioners, valuers, mortgage brokers and real estate agents giving rental forecasts that did not survive contact with reality. The expert opinion comes from the matching profession.

Suing a lawyer takes extra care

Lawyer-on-lawyer claims have one feature the others do not. The legal profession is small, the experts know each other, and the defendant’s insurer fights hard because every paid claim sits on a future premium. You need an independent expert solicitor or barrister to give evidence on what a competent practitioner would have done. Without that expert report, the claim does not get past a strike-out application.

We brief experts from a different state when the Melbourne pool is too close to the defendant. We have run claims against firms of every size, from sole practitioners to the top tier. Ask about the ones like yours on the first call. The full process is set out in our professional negligence claims guide.

How the claim runs, from review to resolution

A professional negligence claim follows a settled path, and knowing it removes a lot of the worry.

Merits review. We read the file, work through the four elements, and give you an honest view of the strengths and weaknesses. If it does not stack up, you hear that at the review, not three months into a file.

Expert evidence. We brief an independent practitioner in the same profession to report on the standard of care and where the defendant breached their duty. This report is the spine of the file, and nothing serious moves without it.

Quantifying the loss. A forensic accountant puts a defensible figure on what the negligence cost you, separating it from losses the market or events would have caused regardless.

The letter of demand and negotiation. We set out the claim to the professional and, in practice, to the professional indemnity insurer standing behind them. Insurers prefer a negotiated outcome to a public judgment, so a well-evidenced demand often opens settlement talks straight away.

Filing and mediation. If negotiation stalls, we issue proceedings in the right court and push the matter to mediation. Most professional negligence matters resolve here, often within months of filing, because both sides can see what a trial would cost and risk.

Trial, if it comes to it. A small share of files run all the way. When they do, the expert report and the loss calculation built at the start are what win them.

The Wrongs Act and proportionate liability

Part IVAA of the Wrongs Act 1958 (Vic) introduces proportionate liability for claims involving economic loss or property damage arising from a failure to take reasonable care. In plain language, if more than one professional contributed to your loss, say a solicitor and a conveyancer, or an accountant and a financial advisor, each pays only their share. Joint and several liability no longer applies to most pure economic loss claims.

That matters for two reasons. You may need to join every concurrent wrongdoer to recover the full loss, and the defendant will try to point the finger at anyone who is now bankrupt, deregistered or out of reach. We pre-empt the apportionment fight at the pleading stage so the gaps do not land on you.

Where we run these matters

The right court depends on the size of the claim.

The County Court of Victoria handles most professional negligence files. It is faster than the Supreme Court, the case management is tight, and the costs scale is workable for claims up to and beyond the million-dollar mark.

The Supreme Court of Victoria is the right venue for high-value or complex matters, particularly where injunctive relief, multiple defendants, or hard points of law are in play. The Commercial Court list inside the Supreme Court moves negligence files quickly.

We sometimes file in the Federal Court of Australia where the negligent conduct also amounts to misleading or deceptive conduct under section 18 of the Australian Consumer Law, which often gives a parallel cause of action on the same evidence. For broader commercial disputes that overlap with a negligence claim, see our commercial litigation page.

We run your claim with the insurer in our sights

Behind the polished lobby of most professional firms sits a professional indemnity insurer whose job is to limit what gets paid out. We act for clients who have suffered loss because a trusted advisor failed in their duty of care, and we run the claim with that insurer in mind from day one. A precise letter of demand, an expert report the insurer cannot dismiss, and a clear figure for the loss are what move a matter to a settlement that actually reflects the harm done to you.

What it costs

The first call is free and the first review is honest. If the claim does not stack up you hear that on the call, not after you have spent money finding out.

What it costs from there is driven by the merits review, the expert evidence, and how far the insurer makes you go. The expert report is the item most clients have not budgeted for, so we agree that spend with you before anyone is briefed. Disbursements and court fees have to be funded as the file moves too, and we work that plan out with you early rather than springing it on you later. We scope your matter in the free first call. Timelines, who we act for and what that call involves are answered in our frequently asked questions.
