Diminished value

Who pays diminished value — my insurer or theirs?

The main path: their insurer

When another driver is at fault, your diminished value claim sits inside your property damage claim against that driver. Their liability coverage exists to pay for damage their driver caused to other people and their property. A car that is worth less after a proper repair because it now has an accident history has suffered a real loss, and that loss belongs in that claim.

That framing matters in the conversation with the adjuster. You are not asking the other insurer for a courtesy or an add-on. You are identifying an element of loss their driver caused, separate from the repair bill itself. Keep it labeled that way in writing, with its own evidence, rather than folding it into a general request for more money.

No deductible applies to this third-party claim. A deductible is a feature of claiming under your own policy. Claiming against the at-fault driver's liability coverage does not carry one. If an adjuster applies a deductible to a third-party diminished value payment, ask for the basis for that in writing.

If that insurer is slow, unresponsive, or disputes fault, the practical options for dealing with that side are covered in the guide to the other driver's insurer.

The hard path: your own insurer

A first-party claim — claiming diminished value from your own collision coverage — runs into the policy wording. Most collision policies promise, in substance, to repair your car or pay its value if it is a total loss. Insurers read that promise as complete once the car has been properly repaired. The remaining drop in value caused by the accident history is, on that reading, not a separate covered loss.

Courts in most states have upheld that reading of standard collision wording. That does not mean every policy everywhere is identical, and it does not mean you should not read yours. It means you should expect a first-party diminished value demand to be declined on the wording, and should not build your plan around your own insurer paying it when another driver was at fault.

If the at-fault driver is uninsured

When the driver who caused the damage has no insurance, the path changes. Uninsured-motorist property-damage coverage, if you bought it, may respond in some states and under some policies. How that coverage treats diminished value varies — some policies and states treat the claim much like a claim against the at-fault driver, others are narrower.

Read that section of your own policy closely, and ask your insurer for its position on diminished value under that coverage in writing. The broader picture for this situation is in the guide to uninsured motorist claims. Do not assume the coverage is present, or absent, without checking the declarations and the coverage wording itself.

If fault is shared

Many crashes are not all one driver's fault. Under comparative-fault rules, which most states use in some form, what you can recover from the other side is reduced when you share fault. Diminished value is not separate from that math — it is reduced along with the rest of your property damage claim.

Because the reduction rule varies by state, and because a fault dispute can change the value of the whole claim, get the other insurer's fault position in writing early. If you disagree with it, say so in writing and keep the evidence that supports your version — photos, the police report if one exists, and witness details if you have them. The full picture is in What happens if I was partially at fault in the accident?

A practical sequence

1. Identify which claim you have. Third party against the at-fault driver, first party against your own collision coverage, or an uninsured-motorist claim. The answer decides where the demand goes and what wording controls it.
2. Demand in writing, to the correct insurer. Put the diminished value demand in writing to the insurer that actually owes it. A demand sent to the wrong company wastes weeks and can confuse the record.
3. Keep the claims clearly separate. Identify the repair claim and the diminished value demand as separate elements of loss in your letter. State plainly that the repair payment, if already made, covered repairs only.
4. Keep every reply. If an insurer declines, ask for the policy or legal basis in writing. A written denial you can read is more useful than a phone explanation you cannot check.

Frequently asked questions

Who usually pays diminished value?

The at-fault driver liability insurer usually pays it as part of a third party claim, because that coverage owes the loss its driver caused. No deductible applies to that third party claim. Your own collision coverage is a much harder path and usually does not pay first party diminished value.

Does my own insurer have to pay diminished value?

In most states, no, under standard collision wording. Most policies promise to repair the car or pay its value, and courts in most states have upheld that this does not include a separate first party diminished value payment. Georgia is the notable exception, where insurers must assess diminished value on first party claims.

What if the at-fault driver has no insurance?

Uninsured motorist property damage coverage may respond in some states and under some policies, and how it treats diminished value varies. Read that section of your policy closely and ask your insurer for its position in writing. If that coverage is not in your policy, your options against the other driver become much more limited.

What if fault is shared between both drivers?

Comparative fault rules in most states reduce what you can recover from the other side when fault is shared. The diminished value claim is reduced along with the rest of the property damage claim. The exact rule varies by state, so confirm how your state treats shared fault before you settle.
