When a car is involved in an accident, its market value often drops—even after repairs. This loss in value is called diminished value. If someone else caused the accident, you might be able to file a diminished value claim to recover the difference. In Washington State, insurance companies must compensate vehicle owners for this loss, but getting a fair payout isn’t always easy.

What Is a Diminished Value Claim?

Diminished value refers to the reduced resale value of a vehicle after an accident. Even if repairs restore the car to full working condition, its accident history can still lower its worth. Buyers and dealerships often pay less for cars with past damage, even if the repairs are high quality.

Washington State law allows vehicle owners to seek compensation for this loss if another driver was at fault. Unlike repair costs, which cover the physical damage, diminished value claims focus on the financial loss caused by the accident’s impact on the car’s market price.

Types of Diminished Value in Washington

There are three types of diminished value claims:

• Inherent Diminished Value: The most common type, this is the loss in value simply because the car was in an accident, even if repairs were perfect.

• Repair-Related Diminished Value: This happens when the repairs lower the vehicle’s value, such as when non-OEM (original equipment manufacturer) parts are used or improper fixes leave visible defects.

• Immediate Diminished Value: This is the difference between what the car was worth before the accident and what it is worth immediately after, before any repairs are done.

Most claims focus on inherent diminished value since even well-repaired cars lose resale value.

How to File a Diminished Value Claim in Washington

To file a successful diminished value claim, you need to follow several steps:

1. Gather Evidence – Document everything about the accident and your car’s condition before and after the crash. This includes repair invoices, accident reports, and a professional appraisal of your vehicle’s pre-accident value.

2. Contact the At-Fault Driver’s Insurance – Washington follows an at-fault insurance system, meaning the responsible driver’s insurer should pay for diminished value. You’ll need to submit a formal claim along with supporting evidence.

3. Get a Professional Appraisal – A certified auto appraiser can provide an estimate of how much value your car lost. Some insurers try to undercut claims, so having a third-party valuation helps strengthen your case.

4. Negotiate with the Insurance Company – Insurers often dispute diminished value claims or offer low settlements. Be prepared to counter their offer with your appraiser’s report and market research showing similar cars with and without accident history.

5. File a Lawsuit if Needed – If the insurance company refuses a fair settlement, you may need to take legal action. Washington’s statute of limitations for property damage claims, including diminished value, is three years from the accident date.

How Is Diminished Value Calculated?

One common method insurance companies use is the 17c Diminished Value Formula, which considers:

• The car’s pre-accident value

• A damage multiplier based on severity

• A mileage deduction (higher mileage reduces the claim amount)

However, this formula often undervalues claims. Independent appraisers usually provide a more accurate estimate based on real-world sales data.

Challenges in Diminished Value Claims

Insurance companies don’t always pay diminished value claims without a fight. Common challenges include:

• Denial of Claims – Some insurers argue that modern repair techniques eliminate value loss.

• Lowball Offers – Companies may offer less than the car’s actual diminished value.

• Disputes Over Damage Severity – The insurer might claim the accident wasn’t severe enough to impact value.

Having a lawyer can help counter these tactics and increase your chances of getting fair compensation.
