Most drivers think the financial loss ends once the body shop repairs the car. That is not always true.
Even after quality repairs, a vehicle can be worth less simply because it now has an accident history. That loss is called diminished value. It often shows up when you try to sell, trade, or refinance the vehicle.
In Louisiana, you may be able to recover diminished value when another driver caused the crash. Knowing how this claim works can help you avoid accepting less than the vehicle is actually worth. A New Orleans car accident law firm can also review the insurer’s offer if the number seems too low.
Here is what Louisiana drivers should know.
What Diminished Value Means
Diminished value is the difference between your car’s market value before the crash and its value after repairs.
A car may look fully repaired, drive normally, and still lose resale value because the accident appears on a vehicle history report. Buyers and dealers often pay less for a car with a reported crash, even when the repairs were done correctly.
For example, a 2022 SUV may have been worth $35,000 before the crash. After repairs, it may only sell for $30,000 because of its accident history. That $5,000 difference is diminished value.
This is separate from the repair bill. Repairs fix the visible damage. Diminished value is the loss remaining after repairs are complete.
The Three Types of Diminished Value
There are three common types of diminished value. The one that matters most in most claims is inherent diminished value.
Immediate Diminished Value
Immediate diminished value is the drop in value right after the crash, before repairs are made. At that point, the vehicle is damaged and may not be safe to drive.
Insurers rarely pay this as a separate claim because repairs usually address part of that loss.
Inherent Diminished Value
Inherent diminished value is the most common type. It is the permanent loss in resale value that remains after proper repairs.
This happens because many buyers avoid vehicles with accident history, even when the work was done well.
Repair-Related Diminished Value
Repair-related diminished value happens when the quality of the repairs lowers the car’s value.
Examples include:
- Mismatched paint
- Poor panel alignment
- Aftermarket parts instead of original manufacturer parts
- Ongoing steering, suspension, or alignment issues
- Visible signs that the vehicle was repaired
How Insurers May Calculate Diminished Value
Many insurance companies use a method called the 17c Formula. It is common, but it often yields a lower figure than the vehicle’s actual market loss.
The formula usually works like this:
- The insurer starts with the vehicle’s pre-accident value, often using Kelley Blue Book, NADA, or another valuation source.
- It applies a 10% cap as the maximum possible diminished value.
- It adjusts that number based on damage severity.
- It reduces the amount again based on mileage.
For example, a $30,000 vehicle may start with a $3,000 base loss. If the damage is considered moderate, it may be reduced to $1,500. A mileage adjustment may reduce it again to $1,200.
That number may not reflect what the vehicle actually lost in the market.
Louisiana law does not require the 17c Formula. If the insurer’s number seems too low, an independent appraisal can give you stronger evidence of the vehicle’s real loss in value.
Louisiana Law on Diminished Value Claims
You may be able to pursue diminished value if another driver caused the crash. A few rules can affect the claim.
Comparative Fault
Louisiana uses comparative fault under La. Civ. Code art. 2323.
For crashes on or after January 1, 2026, Louisiana applies modified comparative fault. Your recovery is reduced by your share of fault. If you are 51% or more at fault, you recover nothing.
For crashes before that date, the older pure comparative fault rule may apply.
Filing Deadline
Property damage claims, including diminished value claims, are subject to Louisiana’s filing deadline.
For crashes on or after July 1, 2024, you generally have two years from the date injury or damage is sustained to file a lawsuit under La. Civ. Code art. 3493.1. Older crashes may fall under the prior one-year deadline.
Waiting too long can weaken the claim or prevent recovery.
Who Can File?
In most cases, diminished value is claimed against the at-fault driver’s insurance company.
Your own insurance policy usually does not pay diminished value unless your policy includes specific coverage for that loss. Policy language matters, so it is worth checking before assuming the loss is excluded or covered.
How to Estimate and File a Diminished Value Claim
A diminished value claim needs proof. A phone call to the insurer is usually not enough.
| Step | What It Involves | Why It Matters |
| Appraisal | Hire an independent vehicle appraiser | Helps show the real market loss |
| Documentation | Collect repair invoices, photos, and value reports | Gives objective support for the claim |
| Demand letter | Send the claim to the at-fault insurer | Starts the formal review process |
| Negotiation | Compare the insurer’s number with your appraisal | Helps challenge a low offer |
| Legal review | Get advice if the dispute continues | Helps protect your rights before the deadline |
Insurers often start low. A clear appraisal, repair records, photos, and market comparisons can make the claim much harder to dismiss.
Common Mistakes to Avoid
Many drivers lose out on diminished value because they do not realize it is separate from repairs.
- Assuming repair costs are the only recoverable property loss
- Believing the insurer will automatically include diminished value
- Accepting the first offer without checking the car’s market loss
- Waiting until the filing deadline is close
- Failing to take photos before and after repairs
- Skipping an independent appraisal when the loss is significant
The stronger your records are, the easier it is to show what the crash actually cost you.
Frequently Asked Questions
What qualifies as diminished value after a crash?
Diminished value is the drop in your vehicle’s resale or trade-in value after an accident. It can persist even after the car is professionally repaired and appears normal.
Can I file a diminished value claim if I was partially at fault?
Yes, in some cases. Louisiana’s comparative fault rule may still allow a reduced recovery based on your percentage of fault. For crashes on or after January 1, 2026, recovery is barred if you are 51% or more at fault.
Does my own insurance cover diminished value?
Usually not under a standard policy. Most diminished value claims are made against the at-fault driver’s insurer. Your own policy may only help if it includes specific diminished value coverage.
How do I prove diminished value?
You can use an independent appraisal, repair invoices, photos, vehicle history records, and market comparisons showing the car’s value before and after the crash.
What if the insurer’s offer is too low?
You can push back with an independent appraisal and market evidence. If the insurer still refuses to offer a reasonable amount, get legal advice before the filing deadline passes.
