What a diminished value claim is and when you can file one

A diminished value claim is a request for money to cover the drop in your car's resale price after it has been in an accident and repaired. Even when repairs are done well, a car with accident history typically sells for less than an identical car with no damage record. A diminished value claim asks the at-fault driver's insurance company to pay you the difference.

You can file a diminished value claim only if another driver caused the accident. If you were at fault, your own insurance company will not pay for diminished value — that is a rule in most states. The claim is separate from paying for the actual repair work; it covers only the lost value.

Not every state allows diminished value claims. Some states recognize them fully, some recognize them only in limited situations, and some do not recognize them at all. Your state's rules determine whether you can pursue this claim and how much you can recover.

Key Takeaways

  • Diminished value claims pay for the loss in resale price after an accident, separate from repair costs, and only when another driver was at fault.
  • Your state must allow diminished value claims for you to file one; about 30 states recognize them in some form, while others do not.
  • You will need repair estimates, your car's pre-accident value, and documentation of the accident to support your claim.
  • The at-fault driver's insurance company must agree to pay, or you can pursue the claim in small claims court or through your own insurance if you have collision coverage.

Which states allow diminished value claims

Roughly 30 states allow diminished value claims in at least some situations. The rules vary widely. Some states allow you to claim diminished value against the at-fault driver's insurance company. Others allow it only if you have collision coverage on your own policy and file against your own insurer. A few states allow both routes.

States that generally recognize diminished value claims include Georgia, South Carolina, Alabama, Mississippi, Connecticut, Delaware, Florida, Illinois, Indiana, Iowa, Louisiana, Michigan, Minnesota, Missouri, New Hampshire, New York, North Carolina, Ohio, Pennsylvania, Tennessee, Texas, Virginia, West Virginia, and Wisconsin. Even within these states, the rules about how much you can recover and what proof you need may differ.

States that do not recognize diminished value claims include California, New Jersey, and New York (though New York does allow it in limited cases). If you live in a state that does not recognize diminished value, you cannot recover this loss through an insurance claim, though you may be able to pursue it in court against the at-fault driver directly.

Before filing a claim, check your state's specific rules. Your state insurance commissioner's office or your state bar association can tell you whether diminished value claims are allowed where you live.

How to calculate the value your car lost

Diminished value is not a fixed percentage. It depends on your car's age, mileage, the severity of the damage, and the quality of the repairs. A newer car with low mileage typically loses more value than an older car. A car that was hit hard and required major repairs loses more value than one with minor damage.

Three common methods exist for calculating diminished value. The sales comparison method looks at what similar cars with accident history sold for compared to identical cars with no history. The formula method applies a percentage to your car's pre-accident value based on damage severity — typically 10 to 20 percent of repair costs, though this varies by state and insurer. The informed appraisal method brings in a professional appraiser who inspects your car and provides a written estimate of value loss.

You do not need to use all three methods. Start by gathering your car's pre-accident value (use Kelley Blue Book, NADA Guides, or Edmunds), your repair estimate, and photos of the damage. If the at-fault driver's insurer disputes your claim, you may need to hire an appraiser to defend your number, which typically costs $300 to $600.

Documents you will need to file a claim

Gather these documents before contacting the at-fault driver's insurance company. First, you need proof of the accident: the police report number, the date and location, and the other driver's insurance information. Second, collect your car's pre-accident value using a valuation tool like Kelley Blue Book or NADA Guides — print or screenshot the result with today's date.

Third, get repair estimates from at least one repair shop, preferably two. The estimate should itemize the damage and list parts and labor separately. Fourth, take photos of the damage before repairs begin and keep them organized by date. Fifth, keep all repair invoices and receipts once the work is done.

Finally, document your car's condition before the accident if you can — maintenance records, service history, or photos showing the car in good condition help show that the damage was the sole cause of value loss. If you have already sold the car, gather any documentation showing the sale price was lower than comparable cars without accident history.

How to file a diminished value claim with the at-fault driver's insurance

Contact the at-fault driver's insurance company and ask to file a diminished value claim. You will need the claim number from the original accident claim. Provide your documents: the police report, your pre-accident valuation, repair estimates, and photos. Write a brief letter explaining that you are claiming the difference between your car's value before the accident and its value after repair.

The insurer will review your claim and either approve it, deny it, or offer a lower amount than you requested. If they approve it, payment typically arrives within two to four weeks. If they deny it or offer too little, you have options: you can negotiate further with the insurer, file a complaint with your state insurance commissioner, or pursue the claim in small claims court.

Small claims court is an option if your state allows diminished value claims and the amount in dispute is within your state's small claims limit (usually $5,000 to $10,000). You will need to file paperwork with the court, pay a filing fee (typically $50 to $200), and appear before a judge. Bring your documents and be prepared to explain how you calculated the value loss.

Using your own insurance if the at-fault driver's insurer refuses

If you have collision coverage on your own auto insurance policy, some states allow you to file a diminished value claim with your own insurer instead of the at-fault driver's company. This route can be faster because your own insurer already has your claim information. However, you will still need to pay your collision deductible, and your insurer may deny the claim if your state does not recognize diminished value or limits it in certain ways.

Contact your own insurance agent and ask whether your policy and state allow diminished value claims. If they do, file the claim with your insurer using the same documents you would send to the at-fault driver's company. Your insurer may then pursue the at-fault driver's insurer for reimbursement in a process called subrogation.

One drawback: filing a claim with your own insurer may affect your rates, even though you were not at fault. Ask your agent whether a diminished value claim will trigger a rate increase before you file.

What happens if your state does not allow diminished value claims

If your state does not recognize diminished value claims through insurance, you still have one option: sue the at-fault driver directly in civil court for the value loss. This is different from an insurance claim. You are asking a judge or jury to order the at-fault driver to pay you out of their own pocket.

To pursue this route, you will need to file a lawsuit in your state's civil court, typically in small claims court if the amount is small enough. You will need the same documents: proof of the accident, your car's pre-accident value, repair estimates, and evidence of the value loss. The at-fault driver's insurance company will likely defend them, but the claim is against the driver personally, not the insurer.

This process takes longer than an insurance claim — often several months — and requires you to appear in court. Many people find it not worth the time and expense unless the value loss is substantial. Consult a local attorney to understand your options in your state.

Frequently Asked Questions

Can I claim diminished value if I was partially at fault for the accident?

No. Diminished value claims require that the other driver be fully at fault. If you share any fault, most states do not allow you to file a diminished value claim against the other driver's insurer. Some states use comparative fault rules that reduce your recovery by your percentage of fault, but diminished value claims typically require zero fault on your part.

How long do I have to file a diminished value claim?

Most states have a statute of limitations of two to four years from the date of the accident, but insurance companies often expect claims within one to two years. File as soon as you have your repair estimate and pre-accident valuation. Waiting longer makes it harder to prove the damage caused the value loss.

Will filing a diminished value claim raise my insurance rates?

Filing against the at-fault driver's insurance company should not raise your rates because you were not at fault. Filing against your own insurance company may raise your rates even though you were not at fault, depending on your insurer's policy. Ask your agent before filing with your own company.

What if the repair shop says the car is a total loss?

If your car is declared a total loss, you cannot file a diminished value claim because the car no longer exists to lose value. Instead, your insurance will pay you the car's pre-accident value minus your deductible. If you disagree with that valuation, you can dispute it with the insurer.

Do I need a lawyer to file a diminished value claim?

For small claims court, you do not need a lawyer and typically cannot bring one. For civil court, a lawyer can help, but many people handle small diminished value claims on their own. If the amount is large or the insurer is difficult, consulting a personal injury attorney may be worth the cost.
