You discover the policy won’t respond. The insurer declines. The broker says “we placed what you asked for.” Your business is staring down an uninsured loss.
Can you sue your broker?
The short answer: yes, if the broker genuinely failed in their duty and that failure caused your loss. The longer answer: proving it is harder than most people expect. Not every placement mistake is a viable negligence claim. Not every declined claim means the broker got it wrong.
The real question is not whether you can sue. It’s whether you can prove the elements that matter: duty, breach, causation, and loss.
And causation is where most claims live or die.
Key Takeaways
- Duty of care: Insurance brokers owe clients a duty to arrange suitable cover and advise on policy gaps, but the scope depends on instructions and the relationship.
- Breach is only half the battle: Proving the broker made a mistake does not guarantee success, you must show the mistake caused the loss.
- Causation requires evidence: You need to prove better cover was available, the broker should have recommended it, and it would likely have responded to the claim.
- Client conduct matters: Poor instructions, incomplete disclosure, or failure to check documents can weaken or destroy your claim.
- Compensation is not automatic: Recovery depends on proving the loss flowed from the broker’s breach, not just from the policy’s failure.
- Act quickly: Preserve emails, policy schedules, proposal forms, and claim correspondence, and get advice before the limitation clock runs out.
What an Insurance Broker Is Expected to Do
An insurance broker is not just a policy placer. They are an adviser.
When you engage a broker, you are paying for more than administrative work. You are paying for expertise: someone who understands your business, identifies your risks, and arranges cover that actually protects you when things go wrong.
That brings obligations.
A broker must understand what you need, recommend suitable products, explain gaps and exclusions, and ensure the policy reflects what you reasonably expected. If the broker knows you need business interruption cover for a pandemic, or cyber cover for a data breach, or public liability that includes contractual liability, they cannot place a policy that silently excludes those risks and walk away.
They also have to warn you when your instructions won’t deliver the cover you think you’re getting. If you ask for “full cover” but the market won’t provide it, the broker must tell you. If a particular risk is excluded or limited, the broker must explain it in plain terms. If a condition precedent could void the policy, you need to know before the claim.
The law calls this a duty of care. The practical reality: a broker who takes your money and leaves you materially underinsured may be liable if things fall apart.
Keep every email, every renewal document, and every policy schedule. If a dispute arises, the first thing your lawyer will ask for is a paper trail showing what you asked for, what the broker promised, and what you actually received.
When a Mistake May Amount to Negligence
Not every placement error is negligence.
A broker arranges a policy that later proves inadequate. Does that automatically mean they breached their duty? No. The question is whether they failed to meet the standard expected of a reasonably competent broker in the circumstances.
Here’s what that looks like in practice.
You tell the broker you need cover for a specific risk, and they place a policy that excludes it without warning you. That’s likely negligence. The broker should have either secured the cover or told you it wasn’t available.
You ask for professional indemnity cover, and the broker places a policy with a claims-made trigger without explaining what that means or how retroactive dates work. Years later, a claim arises from an earlier period, and the policy doesn’t respond. The broker may be liable if they failed to advise on the structure and its limitations.
A broker renews your policy year after year without reassessing whether it still suits your business. Your operations have changed. You’ve taken on new risks. The broker never asked. When the claim hits, you’re underinsured. That could be negligence too.
The common thread: the broker either failed to act on clear instructions, failed to give adequate advice, or failed to warn about a material gap.
But here’s what does not automatically equal negligence: the insurer declines a claim. That’s a separate question. The insurer’s decision may be correct under the policy terms. The broker’s job was to place a policy that would respond if you met the conditions. If you didn’t meet the conditions, non-disclosure, late notification, breach of warranty, the broker may not be at fault.
And no, a broker is not expected to be psychic. If you gave incomplete instructions, withheld information, or failed to disclose material facts, the broker cannot be blamed for a policy that doesn’t fit perfectly.
The real test: did the broker do what a competent broker should have done, given what they knew and what you asked for?
A declined claim is not proof of broker negligence. The question is whether the broker placed suitable cover based on your needs and instructions, not whether the insurer ultimately paid.
Why Missing Cover Is Not Enough on Its Own
You discover a gap in your policy. You’re upset. The broker placed a policy that doesn’t cover the loss. Surely that’s enough to sue?
Not quite.
Proving the broker was negligent is only the first step. You also have to prove that breach caused your loss. And that’s where most claims stumble.
Here’s the problem. Even if the broker got it wrong, you still need to show that if they had done their job properly, you would have had cover that responded. That requires evidence. Real evidence, not assumptions.
Can you show that better cover was available in the market at the time? Can you prove the broker should have recommended it? Can you demonstrate that you would have taken that cover if advised? And critically, can you prove the insurer would likely have paid the claim under that alternative policy?
If the answer to any of those questions is no, your claim may fail.
Here’s an example. A broker fails to secure cyber cover. A data breach occurs. You sue the broker. But if no insurer in the Australian market was willing to provide that cover for your industry at the time, or if the premium was so high you wouldn’t have paid it, the claim collapses. The broker’s failure didn’t cause the loss. The unavailability of cover did.
Or consider this: the broker places a policy with a specific exclusion. You later suffer a loss that falls within that exclusion. You argue the broker should have warned you. Fair enough. But if you can’t prove an alternative policy existed without that exclusion, or that you would have paid more for it, what did the broker’s silence actually cost you?
Nothing. Because you would have ended up in the same position anyway.
This is the causation hurdle. It’s not enough to say “the broker got it wrong.” You have to prove the broker’s mistake made a material difference to the outcome.
Before you commit to a claim, gather evidence of what cover was available at the time, what it cost, and whether it would have responded. Without that, the negligence claim is theoretical, not actionable.
How Causation Works in Broker Claims
Causation is where broker negligence claims succeed or fail. And it’s more complex than most people expect.
The law does not just ask “did the broker make a mistake?” It asks “did that mistake cause the loss you’re claiming?”
To prove causation, you need to construct a counterfactual: what would have happened if the broker had acted properly? Would you have had cover? Would the insurer have accepted the risk? Would the policy have responded to this claim?
Let’s break that down.
First, you need to show that if the broker had given proper advice or arranged proper cover, you would have acted on it. If the broker failed to recommend cyber insurance, you need to prove you would have bought it. If the evidence shows you repeatedly declined optional covers to save on premiums, that’s a problem. Your claim weakens.
Second, you need to prove that the cover the broker should have arranged was actually available. This means identifying specific policies, insurers, or products that were in the market at the relevant time. It’s not enough to say “a better policy must have existed.” You need evidence: quotes, underwriting terms, policy wordings.
Third, you need to show the insurer would likely have issued that cover on terms that would have responded to the claim. If the alternative policy would have required disclosure you didn’t make, or imposed a condition you wouldn’t have met, the claim still fails. The broker’s breach didn’t cause the loss. Your own conduct did.
And here’s the complication: even if all of the above is satisfied, you may still need to prove the insurer would have paid the claim. Some broker negligence claims founder because the client cannot prove the hypothetical claim would have succeeded. If the insurer would have declined for reasons unrelated to the broker’s advice, late notification, policy breach, excluded peril, causation breaks down.
This is sometimes called the “loss of a chance” analysis. You’re not claiming the broker caused the insured event. You’re claiming the broker caused you to lose the chance of a successful insurance claim. The court then assesses whether that chance was real and what it was worth.
Can you see why this is difficult? You’re essentially running a hypothetical insurance claim inside your negligence claim. You need evidence, expert opinion, and a solid understanding of what the market looked like at the time.
Proving a broker’s mistake is only half the job. Proving that mistake caused the uninsured loss requires reconstructing what should have happened and showing it would likely have led to cover that responded.
What Evidence You Need Before You Sue
If you’re serious about a broker negligence claim, you need a file. A comprehensive, well-organised file that proves every element.
Start with the broker relationship. Gather every piece of correspondence: the initial instructions you gave, the emails where you explained your risks, the renewal documents, the policy schedules, the endorsements. If the broker sent you a proposal form, keep it. If they sent summaries or advice notes, keep those too.
You need evidence of what you asked for. “I told them I needed full cover” is not enough. You need the email where you said it, the meeting notes, the terms of engagement. If your instructions were verbal, document them now while your memory is fresh.
Next, gather the policy documents. The full wording, not just the schedule. The key-facts document if there is one. Any mid-term adjustments or endorsements. The claims notification requirements. The exclusions and conditions. You need to understand what you actually bought, not what you thought you bought.
Then collect the claim documents. The insurer’s decline letter. The claim form. Any correspondence about why the policy didn’t respond. If the insurer is pointing to a specific exclusion, condition, or non-disclosure, you need that in writing.
Now the harder part: evidence of the alternative. What cover was available in the market at the time? What would it have cost? What terms would it have been offered on? This usually requires expert evidence: another broker, an underwriter, or an insurance expert who can say “yes, this cover was available, and here’s what it looked like.”
You also need evidence of the broker’s advice, or lack of it. If the broker never warned you about a gap, that needs to be clear from the file. If they did warn you but you chose not to take the cover, that’s a problem for your claim. If they recommended something inadequate and you relied on their expertise, that strengthens it.
Finally, evidence of loss. What did the uninsured event cost you? Can you quantify it? Can you show it’s the kind of loss the missing cover would have addressed?
Without this evidence, the claim is speculative. With it, you have something a court can assess.
Do not wait until you’ve instructed a lawyer to start gathering evidence. Emails get deleted, memories fade, and policy documents go missing. Build the file now, while the trail is still warm.
What the Broker May Argue in Response
A broker facing a negligence claim has defences. Strong ones. And you need to know what they are before you commit to litigation.
The first line of defence: you didn’t give clear instructions. The broker will say “we placed what you asked for.” If your instructions were vague, incomplete, or contradictory, that’s a real problem. A broker is not expected to read your mind. If you said “arrange the usual cover” without specifying what risks mattered most, the broker may argue they met the standard.
The second: you failed to disclose material facts. Insurance is a contract of utmost good faith. If you withheld information, misrepresented your business, or answered proposal questions incorrectly, the broker may say “we placed the policy based on what you told us.” If the insurer would have declined or restricted cover had the true facts been known, the broker’s alleged failure becomes irrelevant. The policy would never have responded anyway.
The third: you signed the documents without reading them. Proposal forms, policy schedules, renewal summaries. If the broker sent you a document that disclosed the gap or exclusion, and you signed it or acknowledged it without objection, the broker will argue you accepted the risk. You cannot now claim you weren’t warned.
The fourth: the cover you claim you needed was not available, or not available at a price you would have paid. The broker may produce evidence that the market would not insure the risk, or that the premium was prohibitive, or that the terms would have been so restrictive you would have rejected them anyway.
The fifth: even with better advice, you would have made the same decision. This is the “it wouldn’t have mattered” defence. If the broker can show you had a pattern of declining optional covers, or prioritising cost over comprehensiveness, they may argue you wouldn’t have bought the missing cover even if recommended.
And finally: the loss would have occurred regardless. If the claim would have been declined for reasons unrelated to the broker’s advice, late notification, breach of warranty, excluded peril under any available policy, the broker argues their breach caused no loss.
These are not trivial defences. They require you to prove not just that the broker got it wrong, but that you did everything right, that better cover existed, and that you would have taken it.
A broker negligence claim is not one-sided. The broker will scrutinise your instructions, your disclosure, your conduct, and the availability of alternatives. Be ready to defend your own role in the relationship.
What Compensation Might Look Like
If you succeed, what do you actually recover?
The goal of a negligence claim is to put you in the position you would have been in if the broker had performed their duty properly. That means compensating you for the loss you suffered because you didn’t have the right cover.
Usually, that’s the amount the insurer would have paid under the policy the broker should have arranged. If the broker failed to secure business interruption cover, and you lost income during a shutdown, the measure of loss is the amount the insurer would likely have paid under a proper policy, less any excess or deductible.
But it’s not automatic. You still need to prove what the insurer would have paid. That might require expert evidence on how the hypothetical claim would have been assessed, whether any policy limits or sub-limits would have applied, and what the likely settlement figure would have been.
You can also recover defence costs if you were sued and had to defend without insurance. Legal fees, expert costs, settlement payments. But again, only to the extent those costs would have been covered under the policy the broker should have placed.
Some claims include consequential losses: business interruption beyond the insured period, loss of profit, damage to reputation. The test is whether those losses were a reasonably foreseeable consequence of the broker’s breach. That’s a harder argument, and it depends heavily on what the broker knew about your business and the importance of the cover.
You cannot recover for losses that would have occurred anyway. If the insurer would have declined for reasons unrelated to the broker’s failure, or if the policy would have capped the payout below your actual loss, your damages are limited accordingly.
And you have a duty to mitigate. If you discovered the gap before the loss occurred and failed to take steps to fix it, that may reduce your recovery.
Interest and costs may also be available, depending on the nature of the claim and how the litigation proceeds.
The bottom line: compensation is tied to what you lost because the broker failed, not what you lost generally. Proving that figure requires reconstructing the hypothetical insurance claim and showing what it would probably have delivered.
Quantifying damages in a broker negligence claim often requires expert evidence from insurance professionals who can say “this is what the claim would likely have settled for.” Budget for that cost early.
What to Do Next If You Think the Broker Got It Wrong
You’ve read the decline letter. You’ve checked the policy. You think the broker failed. Now what?
First, do not assume the worst. Not every declined claim means the broker was negligent. The insurer may be wrong. The policy may respond after all. Get a second opinion on the coverage question before you pivot to suing the broker.
Second, preserve everything. Emails, policy documents, claim correspondence, renewal records, proposal forms, meeting notes. If you delete an email or throw out a document, you may lose the evidence you need to prove the claim.
Third, review the timeline. When did the broker relationship begin? When was the policy placed? When did the loss occur? When did you discover the problem? Limitation periods matter. In most Australian jurisdictions, you have six years from the date of loss to bring a negligence claim, but there are exceptions and complexities. Do not assume you have unlimited time.
Fourth, assess the strength of your position honestly. Can you prove what you asked for? Can you show the broker failed to deliver it or warn you? Can you demonstrate that better cover existed and would have responded? If the answer to any of those questions is uncertain, the claim may not be viable.
Fifth, engage a lawyer who understands both insurance and professional negligence. This is not a straightforward dispute. You need someone who can assess coverage, causation, and the economics of the claim. A lawyer who only does insurance may miss the negligence elements. A lawyer who only does negligence may miss the coverage issues.
Sixth, consider alternatives to litigation. Some broker negligence claims can be resolved through negotiation, mediation, or complaints processes. If the broker’s insurer is willing to settle, that may be faster and cheaper than a contested hearing. If the broker is uninsured or underinsured, litigation may be uneconomic even if you’re right.
And finally, be realistic about what you’re seeking. If your goal is to recover the uninsured loss, the claim needs to be strong on causation and quantum. If your goal is to punish the broker or make a point, litigation is an expensive and uncertain way to do it.
The right lawyer will not just tell you whether you have a claim. They will tell you whether it is worth running, what evidence you need, what the likely recovery is, and what the risks are if it fails.
Do not wait until the limitation period is almost up to seek advice. The evidence-gathering and expert assessment process takes time, and you need a clear view of the claim’s strength before you commit.
The Real Test: Was the Broker’s Failure the Reason You’re Uninsured?
Litigation should not feel like wandering through fog, stumbling from one procedural step to another. Yet for many clients considering a broker negligence claim, that is exactly what it is.
The pathway to a successful claim is not built on outrage or disappointment. It is built on evidence, causation, and proof that the broker’s failure made a material difference.
Can you sue your insurance broker for negligence? Yes. But the real question is whether you can prove the elements that matter: that the broker owed you a duty, breached it, and that breach caused a loss you can quantify.
And the hardest part is not proving the broker got it wrong. It is proving that if they had got it right, you would have had cover that responded.
The right lawyer will not just handle your case. They will give you clarity. And clarity is the most powerful tool you can take into any dispute.
