Limitation Act NSW
Finding out that a professional you trusted—a solicitor, an accountant, or a financial advisor—has made a mess of your affairs is a heavy realization. Beyond the immediate financial or personal stress, there is a legal clock that starts ticking the moment you suffer harm or discover a mistake.
In New South Wales, that clock is governed by the Limitation Act 1969 (NSW).
At Fair Go Australia, we believe that if a professional fails to meet their duty of care, they should be held accountable. However, the law is very firm: if you wait too long to start your claim, you lose the right to seek compensation entirely. Understanding these time limits isn’t just a legal technicality; it’s the difference between getting a fair go and being locked out of the justice system.
The Limitation Act 1969 (NSW) is the rulebook that tells us how long a person has to bring a case to court. Its primary goal is “finality.” The NSW legal system decides that it isn’t fair to have a threat of a lawsuit hanging over someone’s head forever, and it’s also harder to have a fair trial when evidence goes missing or people’s memories fade after a decade.
For anyone who has been harmed by professional negligence, this Act is the most important document to understand. It dictates the window of time you have to file your case in the District Court or Supreme Court of NSW.
In New South Wales, the timeframe for a professional negligence claim isn’t always a straight line. It depends on what went wrong and when you found out about it.
For most claims involving personal injury or specific losses, you generally have 3 years from the date the harm became “discoverable.” This means the date you knew (or a reasonable person in your shoes should have known) that:
In many cases involving “pure economic loss”—for example, an accountant giving you negligent tax advice that results in a massive ATO penalty—the limit is usually 6 years from the date the loss actually occurred.
Regardless of when you discovered the mistake, there is an absolute limit of 12 years from the date the professional actually committed the act of negligence. Once this 12-year window shuts, the law almost never allows a claim to proceed.
One of the most common reasons professional negligence cases get complicated is a disagreement over when the clock actually started. A negligent professional’s insurer will often argue that you “should have known” about the mistake much earlier than you actually did.
Because this “start date” is often a matter of interpretation, it is vital to get an expert legal opinion the moment you suspect something is wrong.
Under Section 60G of the Limitation Act 1969 (NSW), the court does have a small amount of “wiggle room” to extend a deadline, but it is incredibly rare. You would have to prove that it is “just and reasonable” to allow the case to go ahead late.
Relying on a court’s sympathy is a massive gamble. It is far safer to act while you are clearly within the statutory limits.
In NSW, professional negligence claims must generally be commenced within 3 years of the date you became aware (or should reasonably have become aware) of the negligence. Missing this deadline can permanently extinguish your right to claim. If you are unsure whether your limitation period is still open, contact our team for a free assessment as soon as possible.

If a professional intentionally concealed their negligence, the Limitation Act may allow the clock to be “paused” until the fraud or concealment was discovered.
Generally, no. Simply talking to the professional or waiting for them to “fix it” does not stop the legal limitation period. You often need a formal “standstill agreement.”
