Liberty Mutual Diminished Value Claim
Liberty Mutual is one of the country's largest auto insurers — and like the rest, it won't volunteer diminished value. Here's how to file and how to counter a low offer.
Even a flawless repair leaves your car worth less on resale, because the accident is permanent on its history report. That loss is diminished value. If a Liberty Mutual policyholder caused your accident, Liberty Mutual is who you claim it from.
A big national insurer treats this as a negotiation
Liberty Mutual handles claims at national scale, and diminished value sits outside the standard repair workflow. The first figure you hear is an opening position, not a verdict. What changes it is a documented file: a defensible pre-accident value, a repair invoice that shows real severity, a 17c estimate, and comparable listings.
Third-party vs. first-party with Liberty Mutual
Third-party (Liberty Mutual's insured hit you): You claim against their liability coverage, which generally owes diminished value in most states — the stronger position.
First-party (your own Liberty Mutual policy): Depends on your state and policy; many exclude first-party diminished value, while states like Georgia require it. Check your property-damage terms and your state Department of Insurance.

Does Liberty Mutual pay diminished value claims?
If a Liberty Mutual policyholder was at fault, Liberty Mutual generally owes diminished value on your third-party property-damage claim, and most states recognize it. First-party (on your own policy) depends on your state and policy; many exclude it outside states like Georgia that require it.
How do I file a diminished value claim with Liberty Mutual?
Reference your accident claim, state clearly you're claiming diminished value, and submit your pre-accident value, the repair invoice, a 17c estimate, and comparable listings or a licensed appraisal. Keep everything in writing and treat the first offer as a starting point.
How much will Liberty Mutual pay for diminished value?
There's no fixed amount. Insurers often anchor to the 17c formula, which caps at 10% of pre-accident value and reduces for damage and mileage — a conservative floor an independent appraisal often exceeds.
What if Liberty Mutual lowballs my claim?
Counter in writing with your 17c estimate, an appraisal, and comparable listings; then invoke the appraisal clause, your state Department of Insurance, or small-claims court if needed.
