Disputing a total loss valuation

How the insurer's number is built

Most insurers price a totaled car with a valuation report from an outside vendor. The report finds cars for sale or recently sold near you, adjusts each one to look like yours, and averages the result. Then come taxes, fees, and any deductions for prior damage or condition. The NAIC model regulation sets the method for a cash settlement:

• Comparable car: same make, the same or a newer model year, a similar body style, options and mileage.
• Local market: based on two or more comparable cars in your local area, sold or offered in the last 90 days.
• Taxes and fees: applicable taxes and transfer fees on buying that car are included, and only the deductible comes off.
• Deductions: each one, including salvage value if you keep the car, must be itemized and explained.

States adopt the model in their own words, and some go further. Background on the settlement itself is in our guide to total loss claims.

Check the report line by line

Ask the adjuster in writing for the complete valuation report, not a one-page summary. Then check:

• Your car's description. The right trim level, engine, drive type and factory packages. A base trim listed in place of a higher one lowers every comparable the report picks.
• Mileage. Your odometer reading at the time of the loss, and how the report adjusts for comparables with more or fewer miles.
• Each comparable. Is it the same model and trim, is it near you, and is it dated within the window? California requires each comparable to be identified by VIN, stock number or license plate, so you can look it up.
• Condition adjustments. A deduction for wear, rust or prior damage should say what was found and what it cost. Vermont lets an insurer take deductions only if they are justified and detailed after an actual inspection.
• Taxes, title and registration fees. Check that they appear, at your local rate.
• Salvage value, if you keep the car, and who would pay that price.

Build your own evidence

1. Find real comparables. Save dealer listings for the same make, model, year range, trim and similar mileage in your area, with the VIN, the asking price and the date you saw them.
2. Collect your car's records: the window sticker or build sheet, receipts for recent tires, brakes or major repairs, and photos from before the crash.
3. Get dealer quotes in writing for a comparable car, if dealers will give them.
4. Consider an independent appraisal by a licensed appraiser, especially for a rare, modified or high-value car. Ask the fee first and keep the report.
5. Send a written rebuttal that lists each error in the report, attaches your evidence and gives the figure you think is right, with a date for a written reply.

Dealers' asking prices often run above what cars sell for, and insurers may adjust for that. Your case is stronger when your comparables are as close to your car as the insurer's are, and nearer.

Using the 35-day reopen rule

The reopen rule is for the case where the number looked fine on paper but the market says otherwise. Under the NAIC model, if within 35 days of getting the check you show the insurer that you can't buy a comparable car for that amount, it must reopen the claim. California and Washington have their own 35-day versions, with conditions.

1. Note the date the payment or final offer arrived, and count 35 days on a calendar.
2. Shop for a real replacement of the same make, model, trim and similar mileage, and keep the listings and any dealer quotes that come in higher than the settlement.
3. Write to the adjuster before the 35 days end: say you can't buy a comparable car for the amount paid, attach the evidence and ask the insurer to reopen the claim.
4. Ask what it will do next, such as pay more, name a specific car at that price, or explain in writing why it won't.

If the insurer points you to a specific car at its price, go and look at it. A car with a different trim, a branded title or far more miles is not a comparable car, and you can say so in writing.

State rules that can help

The details matter. Washington's reopener doesn't apply if the insurer gave you written notice of a specific comparable car that you didn't buy within five business days. Look up your state's rule in claim rules by state.

If you still disagree

When the only dispute is the amount, check your policy's physical damage section for an appraisal clause. Each side picks an appraiser, and an umpire settles what they can't agree on. Washington has required the clause in auto policies with physical damage coverage issued or renewed since January 1, 2026. Texas requires appraisal terms in personal auto policies delivered, issued or renewed on or after March 1, 2027, and Illinois in auto policies with physical damage coverage issued, renewed or delivered on or after July 1, 2027; see the appraisal clause.

If the insurer won't explain its deductions or ignores the state rule, a complaint to your state insurance department asks it to justify the figure in writing. For a claim against the other driver's insurer, small claims court is another route.

The appraisal clause is a term of your own policy, so it applies when you claim under your own collision or comprehensive coverage. When the other driver's insurer totals your car, you usually have no contract with that company, and the routes are a written rebuttal, a complaint, or a claim in court against the driver. Claiming under your own coverage instead can bring the appraisal clause and your state's first-party rules into play.
