One of the most important things anyone with a potential personal injury claim needs to understand is this: your right to claim is time-limited by law. If you miss the applicable deadline, you may lose your right to any compensation at all — regardless of how serious your injuries are, how clearly someone else was at fault, or how strong your evidence is. Different types of personal injury claims in NSW carry different time limits, and understanding which limit applies to your circumstances is essential. This article covers every limitation period relevant to personal injury law in NSW and explains what you should do if you are concerned you may be running out of time.
Limitation periods exist to ensure that legal disputes are resolved while evidence remains available, witnesses’ memories are fresh, and both parties can respond fairly to the issues in question. From a practical standpoint, these limits mean that injured people must act within a defined legal window — or risk losing their entitlements permanently. While courts have a discretionary power to extend time limits in limited circumstances, extensions are not guaranteed. Defendants will actively oppose them, arguing that the delay has caused them prejudice. Relying on a court granting an extension is always a risk. The safest and most sensible approach is to seek legal advice as early as possible.
If you were injured in a public place, on someone else’s premises, or at a business due to another party’s negligence, you generally have three years from the date of the accident to commence legal proceedings in NSW. This is the limitation period under the Limitation Act 1969 (NSW), and it applies to the vast majority of public liability claims — including slip and fall accidents, injuries at sporting venues, and incidents on council land.
The three-year period runs from the date of “discoverability” — not automatically from the date of the accident itself. A claim is discoverable from the date you knew (or ought reasonably to have known) that your injury occurred, that it was caused by the fault of another person, and that it was serious enough to justify bringing legal action.
For workers compensation claims, the initial claim for weekly payments and medical expenses must be lodged with the insurer within six months of the date of injury. However, claims lodged after six months and within three years may still be accepted if there is a reasonable excuse for the delay. Common reasonable excuses include:
Lump sum permanent impairment claims must be lodged within two years of receiving the permanent impairment assessment. Work Injury Damages claims (modified common law for lost earning capacity) must be commenced within three years of the date of injury.
CTP claims have a layered set of time limits:
Missing the 28-day window does not prevent a valid claim, but results in income support payments starting from the date of lodgement rather than the accident date — potentially losing weeks of income support. Missing the 3-month window is far more serious.
Medical negligence claims are governed by the same three-year discoverability limitation period as public liability claims. However, the “discovery” date in medical negligence cases is frequently later than the date of the treatment or procedure itself — sometimes significantly so. Where a misdiagnosis only becomes apparent months or years later, or where an injury from a procedure was not immediately apparent, the limitation period may run from the later date of discoverability. An absolute longstop of 12 years from the date of the alleged negligent act or omission applies, regardless of when it was discovered.
Where the injured person was under 18 at the time of the accident, the three-year limitation period does not begin until they turn 18. This means that a child injured at age 12 would generally have until they turn 21 to commence proceedings. However, it is strongly advisable to investigate and document the claim as early as possible after the injury — evidence is harder to gather with the passage of time, and early action provides far more options. Parents and guardians should seek legal advice on behalf of injured children without delay.
Claims related to asbestos-related diseases (including mesothelioma), silicosis, and other dust-related conditions operate under special rules in NSW due to the extremely long latency periods of these diseases. The Dust Diseases Tribunal of NSW handles these claims under a distinct legislative regime. If you or a family member has been diagnosed with an asbestos-related or dust-related disease, specialist legal advice is essential and should be sought immediately.
The concept of discoverability is one of the most important — and most misunderstood — aspects of NSW limitation law. A personal injury claim becomes “discoverable” on the first date that the claimant knew or ought reasonably to have known:
In many cases, all three of these facts are known immediately — you slip in a supermarket, you are injured, and you know the supermarket failed to address the wet floor. In other cases — particularly latent diseases, psychological injuries, misdiagnoses, and delayed onset conditions — one or more of these facts may not become apparent until much later. In those cases, the limitation period starts later. Identifying the correct discoverability date requires careful legal analysis.
Under the Limitation Act 1969 (NSW), a court may extend the limitation period where the claimant was not aware, and could not reasonably have been aware, of the facts necessary to make a claim. Courts consider the conduct of both parties, the reason for the delay, whether the defendant is prejudiced by the extension, and the overall balance of justice. Extensions are granted — but they are not guaranteed, and defendants who can show material prejudice from the delay will often succeed in opposing an application.
Seeking a court extension of a limitation period should never be a strategy. It is a last resort. If you are aware that your limitation period may have expired — or is close to expiring — contact a personal injury lawyer immediately. A lawyer may be able to identify grounds for an extension, but they cannot promise one will succeed. The far safer approach is always to seek advice and act early.
You should seek urgent legal advice if any of the following apply to you:
Even well within the limitation period, delay causes serious practical problems for personal injury claims. CCTV footage is typically overwritten within 14 to 30 days. Witnesses move away, forget details, or become unable to be located. Physical evidence changes. Medical records become harder to obtain and interpret. The injury’s impact on your daily life and earning capacity is harder to document years after the event than it is in the immediate aftermath.
The right time to consult a personal injury lawyer is always immediately after you suspect you may have a claim — not after you have waited to “see how things go.” A consultation costs you nothing. Missing a deadline can cost you everything.
