Why Personal Injury Claims Are Rejected In WA: 7 Reasons

Most rejected personal injury claims in WA fail for reasons that were in the injured person’s control. Since 1991 I’ve run these claims in Perth, and the same avoidable gaps come up again and again: thin evidence, a missed step with ICWA or WorkCover, a first doctor’s visit that came weeks too late. A few claims meet a barrier that’s hard to move, such as no duty of care, no way to prove the other side caused the harm, or an injury the law treats as too minor to clear the pain and suffering threshold. Most rejections aren’t like that. Here are seven reasons a personal injury claim gets rejected in WA, what sits behind each one, and the deadline rule that catches people who assume a late claim is already gone.

Why do personal injury claims get rejected in WA?

Personal injury claims are rejected in WA when you can’t prove another party caused your injury, when you miss a deadline that applies to your type of claim, or when you give the insurer room to dispute the injury itself. The usual triggers are weak evidence, shared fault, a delayed medical record, a pre-existing condition, or lodging outside the limits set by WA law.

Each of those has a response. What matters is knowing which one applies to you, because fixing a missed WorkCover step looks nothing like closing a gap in your medical file.

WA personal injury claim deadlines in 2026

Deadlines cause more rejections than any argument about fault. WA runs different clocks for different claims, and the first step is often not the one people worry about. That’s part of why a claim can take time to resolve, and why the early moves matter.

Claim type	First step	Court deadline	If you are late
Motor vehicle (ICWA)	Report the crash and give ICWA written notice as soon as practicable	3 years to start court action	A late notice is not automatically fatal; a court can allow it if ICWA is not materially prejudiced
Workers compensation (WorkCover WA)	Report to your employer and lodge a claim form	3 years for a common law damages action	Delay lets the insurer dispute the work link, so lodge early
Public liability (slip, fall, dog attack)	Written notice to the occupier or their insurer	3 years	Extensions are limited and at the court’s discretion
Criminal injuries compensation	Application to the assessor	3 years from the offence	A late application needs a written request explaining the delay
Medical negligence	Notice to the provider or insurer	3 years from when you knew of the injury	The date you reasonably knew can move when the clock starts

The three-year court limits sit in the Limitation Act 2005 (WA). Save this table, or send it to whoever is helping you. Missing the wrong line on it is the most common avoidable mistake I see.

Reason 1: The evidence does not prove what happened

Claims fail on evidence more than on law. An insurer rejects what it cannot verify, and the burden sits with you to show who was at fault and how badly you were hurt.

The claims that move quickly are the ones where the injured person photographed the scene, saved the other driver’s details, and noted a witness on the day. The ones that stall are built from memory months later. Collect the medical records, the incident or crash report, the photos, and the witness contacts while they still exist. If you are not sure what carries weight, that is one of the first things a lawyer sorts out, and it is why it helps to document your injuries from the start.

Does being partly at fault ruin your claim in WA?

No. Being partly at fault reduces what you can recover, it rarely ends the claim. A WA court works out each side’s share of responsibility and reduces your damages by your share, so being 30 per cent at fault means roughly a 30 per cent reduction, not a rejection.

You may read elsewhere that being “more than 50 per cent at fault” ends a claim outright. That is not how shared fault works in WA, and treating it as a rule talks people out of claims worth looking at. What does lift your share of the blame is your own conduct, such as not wearing an available seatbelt, or travelling with a driver you knew had been drinking. Those facts reduce your compensation rather than bar you from claiming. Tell your lawyer the unflattering details first. Surprises later cost far more than the truth up front.

What happens if you miss a claim deadline in WA?

It depends which deadline. The three-year court limit is strict, and once it passes most claims are gone. The earlier ICWA notice step for a motor vehicle claim is treated differently, and this is where the common assumption is wrong.

Under the Motor Vehicle (Third Party Insurance) Act 1943 (WA), you must give ICWA written notice of a motor vehicle injury claim as soon as practicable. But section 29A lets a court excuse a late or defective notice where ICWA “is not materially prejudiced” by the delay. In plain terms, a missed notice date does not automatically end a motor vehicle claim if the insurer has not lost anything because of the delay. In my experience a late notice is often not the end of a claim, because the real question is whether ICWA has actually been disadvantaged. That is not a reason to sit on a claim, though. Delay it on purpose and you end up arguing about prejudice instead of your injuries.

Reason 4: A pre-existing condition the insurer can point to

A pre-existing condition can sink a claim, but usually only if you let the insurer blur the line. A prior back problem does not bar you from claiming. It hands the other side an argument that your pain was already there and the accident changed nothing.

The counter is medical, not clever wording. Give your lawyer your full history, including the parts you would rather leave out, so a doctor can separate the old condition from the new injury. WA law recognises the aggravation of a pre-existing condition, so an old injury made worse in the accident can still be a claim. Hidden history is what gets used against you, not the history itself.

Reason 5: You waited too long to see a doctor

A gap between the accident and your first medical visit is one of the easiest rejections an insurer can run. No record on the day reads as no injury on the day, whatever you were actually feeling.

Get seen straight away, even when the injury seems small. Some injuries, whiplash and mild concussion in particular, show up days later, and an unrecorded injury is one an insurer will question. Then follow the treatment plan and turn up to your appointments. A file that shows you tried to recover carries more weight than one that shows you pushed through, which is the opposite of what many people expect. If you are wondering how soon to see a doctor, the answer is the same day where you can.

Why do WorkCover claims get rejected in WA?

WorkCover claims in WA are usually rejected when the insurer disputes that work caused the injury, or that the injury is as serious as claimed. The Workers Compensation and Injury Management Act 2023 (WA), which replaced the previous scheme on 1 July 2024, kept that dispute in place.

Report the injury to your employer and lodge a claim form through WorkCover WA; your employer then has seven days to pass it to their insurer. Late reporting and thin medical evidence are what get disputed. If the injury is serious, you may also have a common law claim on top of your standard WorkCover entitlements, and that path carries the three-year court deadline from the table above. The two run on different rules, so it’s worth getting advice on a workers compensation claim before you settle.

Reason 7: The wrong lawyer, or no lawyer at all

You do not need a lawyer to make a claim. The reason representation matters is what a lawyer actually does: test the insurer’s decision, gather the evidence that supports causation, and put your case at its strongest. That is harder to do on your own, because insurers make first offers and liability calls that suit the insurer.

Choose someone who runs WA personal injury claims day to day, and ask who will actually handle your file. At our firm you work directly with a qualified lawyer, and we act on a no win, no fee basis, which means no legal fees are payable unless your claim succeeds. When it does, we pursue party-and-party costs from the insurer, and that covers most of the legal costs. Experience on hard cases is the part you cannot shortcut. I was the instructing solicitor in the 2002 High Court case De Sales v Ingrilli, which removed the old discount for a widow’s chance of remarriage in dependency claims, and I was counsel in the Full Federal Court matter Westrupp v BIS Industries, which confirmed workers compensation cover for fly-in fly-out workers.

How to give your WA claim its best chance

Do a handful of things and most of the common rejections never take hold. See a doctor the same day and keep every injury on the record. Photograph the scene and collect witness details before people scatter. Tell your lawyer the full story, including your own fault and your history. Watch the deadline that applies to your claim type. Get advice early, while the evidence is fresh and your options are open.

If your personal injury claim has been rejected in WA, or you are worried it might be, a rejection is often a starting point rather than the finish. A lawyer can review whether the insurer’s reasons hold up and what options remain. A first consultation with our personal injury lawyers in Perth is free and confidential, and if you cannot travel, we offer home and hospital visits. You can call us on (08) 6558 1786, or after hours on 0411 896 133.

Frequently asked questions

Why do personal injury claims get rejected in WA?

Most rejections come down to proof, timing, or the injury itself. You need to show another party caused your injury, lodge within the deadline for your claim type, and give the insurer no room to argue the injury was pre-existing or overstated. Weak evidence and a delayed first medical visit are the two most common triggers.

How long do I have to make a personal injury claim in WA?

For most claims you have three years to start court action under the Limitation Act 2005 (WA), running from the injury or from when you first knew of it. Motor vehicle claims also need an early written notice to ICWA, and criminal injuries compensation runs three years from the offence. The clocks differ by claim type, so check yours early.

Can I still claim if I was partly at fault?

Yes. In WA, being partly at fault reduces your compensation by your share of responsibility rather than barring the claim. If you are found 25 per cent responsible, you generally recover about 75 per cent. The idea that being over half at fault ends every claim is not how shared fault works in WA.

What if I missed the ICWA notice deadline after a car accident?

A late notice is not automatically fatal. Section 29A of the Motor Vehicle (Third Party Insurance) Act 1943 (WA) lets a court excuse a late or defective notice when ICWA has not been materially prejudiced by the delay. You will need to explain the delay, so it is worth getting advice quickly rather than assuming the claim is gone.

Why was my WorkCover claim rejected in WA?

WorkCover claims are usually rejected because the insurer disputes that work caused the injury, or that it is as serious as claimed. Late reporting to your employer and gaps in your medical evidence make both arguments easier. A rejection can be disputed, and serious injuries may also support a separate common law claim.

Does a pre-existing condition stop a personal injury claim in WA?

No, but it complicates one. WA law recognises the aggravation of a pre-existing condition, so an old injury made worse by the accident can still be claimed. The risk is letting the insurer treat all your symptoms as pre-existing, which is why full disclosure and a clear medical opinion on causation matter.

How much does it cost to challenge a rejected claim?

Under a no win, no fee arrangement, no legal fees are payable unless the claim succeeds. On a successful claim, the firm pursues party-and-party costs from the insurer, which covers most of the legal costs. A first consultation at Soul Legal is free, so getting an opinion on a rejected personal injury claim in WA costs you nothing.
