Litigation Process

What happens at trial in a professional
negligence case

Reaching the trial stage is not a sign that something has gone wrong. For many claimants, it reflects the opposite — the seriousness of what happened to them, and a refusal to accept an outcome that doesn’t reflect the true extent of the harm.

The reality is that most professional negligence claims settle before they ever reach a courtroom. But that doesn’t mean trial is something to be feared or avoided at all costs. When the other side won’t negotiate in good faith, or when the gap between what’s being offered and what’s fair is simply too wide, a trial is how justice gets done.

Understanding how the process works — what actually happens, in what order, and who decides the outcome — takes much of the uncertainty out of it.

When does a professional negligence claim go to trial?

Most claims don’t get there. Settlement negotiations resolve the majority of professional negligence matters before any court hearing takes place. That’s not just a statistic — it reflects the fact that once the evidence is assembled and a credible claim is on the table, the defendant’s insurer generally has a financial incentive to settle rather than run the risk of a judgment.

Trial typically becomes necessary when:

  • Settlement negotiations have genuinely broken down and the defendant refuses to move to a reasonable figure
  • The defendant denies liability outright — not just disputes quantum
  • The case turns on genuinely contested expert evidence that can only be resolved by a judge
  • The defendant is using delay and intransigence as a strategy, and the only way to force the issue is to proceed

There’s also a less-discussed dynamic worth naming plainly: being credibly trial-ready is often what produces a settlement. A defendant who believes you’ll back down rarely offers their best number. A defendant who knows your legal team is prepared to run the matter tends to negotiate differently.

Which court hears the trial?

The court depends on the size of the claim, the state or territory where the negligence occurred, and in some cases the type of professional involved.

  • Supreme Courts of the relevant state handle high-value or legally complex professional negligence claims. These are where the most serious matters are typically heard.
  • District or County Courts handle mid-range claims where the quantum doesn’t meet the Supreme Court threshold.
  • Federal Court of Australia has jurisdiction over certain claims involving financial services, statutory breaches under Commonwealth legislation, or where the defendant is a federally regulated entity.

Procedural rules differ between courts — case management, timetabling, expert evidence requirements, and hearing formats are all governed by the rules of the specific jurisdiction. Your legal team navigates this; it’s part of what you’re engaging them for.

The key stages of a professional negligence trial

A trial doesn’t begin on day one of the hearing. By the time the parties walk into the courtroom, months of preparation have already taken place. Here’s what the process actually looks like from end to end.

Before the hearing, the court issues formal directions. Pleadings are finalised — meaning each party’s legal case is locked in and no new arguments can be introduced without leave. Witness lists are exchanged, expert reports are served on the other side, and any outstanding procedural disputes are resolved. This is the last meaningful opportunity to negotiate before the costs of trial begin accumulating in earnest.

When the hearing begins, each party’s barrister delivers an opening address to the judge. Unlike what most people picture from television, the overwhelming majority of professional negligence trials in Australia are heard by a judge sitting alone — there is no jury in civil professional negligence proceedings. The opening address frames the case — what the evidence will show, what the standard of care was, how it was breached, and what harm followed.

The claimant and their witnesses give evidence. Each witness is examined in chief by their own barrister, then cross-examined by the other side. In professional negligence cases, the claimant’s own account of events — what they were told, what they understood, what they relied on — is often central to the claim. Witness credibility matters here. How a witness holds up under cross-examination can shape how the judge weighs everything else they’ve heard.

This is frequently the most decisive phase. Because the question at the heart of these claims is what a competent professional would have done in the same circumstances, the court relies on qualified experts in the relevant field. Australian superior courts increasingly use concurrent evidence — sometimes called “hot-tubbing” — where opposing experts are questioned at the same time. It tends to expose weak or partisan expert evidence fairly quickly.

After all the evidence is heard, each barrister delivers closing submissions — written, oral, or both, depending on the court and the complexity of the matter. This is where the competing interpretations of the evidence are put directly to the judge. A strong set of closing submissions is often what converts a complicated factual record into a clear legal conclusion.

In most contested professional negligence trials, the judge reserves judgment — meaning they take time after the hearing to write their decision. In complex matters, that can take weeks or occasionally months. The judgment addresses liability, causation, and quantum as separate questions. It’s detailed, it’s reasoned, and it’s binding.

The role of expert witnesses at trial

Expert evidence isn’t window dressing in a professional negligence trial — it’s often determinative. The judge can’t decide whether a surgeon’s technique fell below an acceptable standard without expert guidance. The same applies to legal advice, financial recommendations, engineering designs, and accounting work.

What the court is looking for is independence. An expert who comes across as a hired advocate for one side will have their evidence discounted or rejected. An expert who gives genuinely balanced, well-reasoned evidence — and who can hold their position under cross-examination — carries real weight.

Selecting the right expert, briefing them properly, and making sure their report is properly structured for court purposes is a significant part of what specialist professional negligence lawyers do in the lead-up to trial.

How long does a professional negligence trial take?

Hearing length varies considerably. A straightforward claim against a single defendant might be heard over two to five days. A complex multi-defendant matter — a construction defect claim involving an architect, engineer, and certifier, for example — can run for several weeks.

  • Simple single-defendant claims: 2–5 hearing days
  • Complex multi-defendant claims: potentially several weeks
  • From filing to final judgment in busy state Supreme Courts: typically 18 months to 3 years

Australian courts actively manage civil cases to reduce delay, and directions hearings are used to keep matters moving. But complex professional negligence cases are resource-intensive, and the backlog in superior courts is a real factor in planning your litigation strategy.

What does going to trial cost?

It’s a reasonable question and it deserves an honest answer. Trial costs in professional negligence matters include barrister fees, expert report fees, court filing and transcript costs, and the ongoing work of your instructing solicitor. For a multi-day Supreme Court trial, those costs are significant.

Most claimants who proceed to trial do so under a conditional fee agreement (CFA) — commonly known as no-win, no-fee. Under a CFA, your legal team’s fees are contingent on success. Disbursements — out-of-pocket costs like court fees and expert reports — are a separate question and should be discussed with your lawyer at the outset.

The other consideration is the risk of an adverse costs order if the claim fails. Australian civil courts apply a general costs-follow-the-event rule — meaning the unsuccessful party may be ordered to pay a contribution toward the other side’s legal costs. This risk is real and shouldn’t be glossed over. A good specialist lawyer will give you a realistic assessment of both costs exposure and prospects of success before recommending you proceed.

Can you settle during a trial?

Yes — and it’s more common than people assume. Settlement can occur at any point in the litigation, including during the hearing itself.

One mechanism worth understanding is the Calderbank offer — a formal written offer made by one party to the other that carries costs consequences if it’s unreasonably refused. If a defendant makes a Calderbank offer during trial and the claimant proceeds to judgment but recovers less than the offer, the court may order the claimant to pay the defendant’s costs from the date the offer was made. The reverse applies equally.

These tactical dynamics run throughout the trial. A good legal team stays alive to settlement possibilities even in the middle of a hearing — because sometimes the right outcome is getting a fair resolution rather than waiting for a judge’s verdict.

Act before time runs out

In most Australian states, professional negligence claims must be commenced within three years of the date you became aware — or should reasonably have become aware — of the negligence. Some states apply different periods depending on the type of claim. Missing this deadline can permanently extinguish your right to have your case heard at all.

Frequently asked questions about the trial process

No — the majority settle before reaching a courtroom. Settlement can occur at any stage of the litigation process, from the pre-filing letter of demand through to the eve of trial. That said, being prepared to run a trial to completion is often what produces a reasonable settlement offer in the first place.

In most states, no. Civil professional negligence claims in Australian superior courts are heard by a judge sitting alone. There is no jury. The judge determines both the facts and the law, and delivers written reasons for their decision.

In straightforward matters, a judge may deliver judgment on the day or within a few days. In complex professional negligence cases, judgment is usually reserved. Depending on the court and the complexity of the matter, this can take anywhere from a few weeks to several months.

This is a genuine risk. Australian civil courts apply a general costs-follow-the-event rule, meaning the unsuccessful party is typically ordered to pay a contribution toward the successful party’s legal costs. The amount is usually assessed on a party-party basis — not the full amount — but it can be substantial in a complex trial. This risk should be weighed carefully with your lawyer before proceeding.

An appeal is possible, but it’s not an automatic right to a full rehearing. Appeals in Australian civil matters are generally limited to questions of law or where the trial judge made an identifiable error. Prospects of appeal and the costs involved are something to discuss with your legal team if you receive an unfavourable judgment.
