Vehicle write-off valuation disputes are one of the most common car insurance complaints lodged with the Australian Financial Complaints Authority (AFCA). When an insurer totals your car, the market value assessment they use to calculate the payout is not always accurate — and you have a formal right to dispute it.
Here is how write-off valuations work, where they go wrong, and the step-by-step process for getting a better outcome.
A car is written off when the estimated repair cost exceeds the vehicle's pre-loss market value, or in some states, when it exceeds a statutory threshold percentage of the vehicle's value. Once written off, most insurers pay out the "market value" or "agreed value" specified in the policy.
Agreed value policies nominate a specific payout amount at the time you purchase the policy. The insurer pays that agreed amount regardless of actual market value at claim time. There is little room for dispute on the payout itself, though agreed value policies cost slightly more in premiums.
Market value policies pay out what the car was worth on the open market immediately before the incident. This is where disputes arise. The insurer's assessor uses a valuation methodology — typically referencing Glass's Guide, RedBook, or similar industry databases — and may not account for the specific condition, service history, recent modifications, or local market pricing of your particular vehicle.
Insurer valuation methodologies are systematic but not always accurate for individual vehicles. Common reasons for undervaluation include: using average condition pricing rather than accounting for a well-maintained, low-kilometre car; not reflecting regional market demand where certain vehicles trade above guide prices; failing to account for aftermarket additions that added genuine value; using pricing data that lags a fast-moving used car market (particularly relevant after 2021 when used car prices rose sharply); and applying depreciation assumptions that do not match current market demand for the specific model.
The insurer's first offer is a starting point, not a final position. If you believe your car was worth more, you can and should push back with evidence.
Before you accept the payout or lodge a formal dispute, ask the insurer in writing (email is fine) to provide the valuation methodology they used. Specifically request: which database or guide was referenced, the date the valuation was run, any comparable vehicles used in the assessment, and how vehicle condition was assessed. Under the General Insurance Code of Practice and AFCA rules, insurers are required to explain their decisions.
This step is worth doing because it tells you where their number came from and whether there is a reasonable basis to challenge it. It also creates a written record if you need to escalate.
The most effective disputes are supported by market evidence showing what comparable vehicles were actually selling for at the time of the incident. Gather: three to five current listings for the same make, model, year, and comparable condition on Carsales, CarGurus, or similar Australian platforms; any recent private sale evidence for the same vehicle; dealer quotes or trade-in valuations obtained before the incident; and service records showing above-average maintenance that would support a condition premium.
If you made aftermarket modifications, provide receipts. If the vehicle had specialist features (tow package, sound system, custom wheels), document their value with receipts or current market listings.
Send your counter-evidence to the insurer's internal dispute resolution (IDR) team, not the claims assessor. Every Australian insurer is required to have an IDR process under ASIC's RG 271 requirements. Write a short, factual cover letter: you disagree with the valuation of $(amount), you believe a fair market value is $(your figure), and you are attaching comparable market evidence in support. Request a written response within 30 days.
IDR decisions go to a different assessor and often produce a revised offer, particularly when market comparables clearly support a higher figure.
If the internal dispute resolution process does not produce a satisfactory outcome, you can lodge a complaint with the Australian Financial Complaints Authority (AFCA) at no cost. AFCA is a free, independent service and its decisions are binding on insurers.
AFCA handles vehicle valuation disputes regularly and is willing to look at market comparable evidence. Their process takes 30 to 90 days on average. You do not need a lawyer or advocate to use AFCA — the process is designed for individuals to navigate without professional help.
Before lodging with AFCA, you must have completed the internal dispute resolution process with the insurer. Keep your IDR rejection letter as evidence of having gone through that step.
AFCA can direct the insurer to revise the valuation and pay a higher amount. For personal motor vehicles, AFCA can award up to $500,000 in compensation. In practice, write-off disputes typically involve amounts of $5,000 to $50,000 and are resolved within the standard AFCA process without requiring a full determination hearing.
For high-value vehicles or where the gap between the insurer's offer and your estimate is large, an independent vehicle valuation from a licenced assessor ($200 to $500) provides professional evidence for an AFCA submission. For a vehicle dispute involving $10,000 or more, this is a worthwhile investment.
Arguing about what you paid for the car originally is not relevant to market value at the time of the incident — depreciation is real. Similarly, what it will cost to replace the vehicle with a comparable one is relevant but only if you support it with current market listings, not a general assertion. Emotional arguments about sentimental value are not part of AFCA's assessment framework.
