Louisiana generally rejects first-party inherent diminished value after adequate repairs. State statute expressly authorizes qualifying third-party diminution claims. A label such as “recognized” does not make payment automatic. You still have to prove a real market loss and preserve the right claim against the right party.
The authority to start with
La. R.S. 9:2800.17; Campbell v. Markel American Insurance Co., 822 So. 2d 617 (La. Ct. App. 2001)
Why this is cautious: Some authorities are old, unpublished, or address policy wording rather than every possible claim. “Unclear” means we did not find controlling automobile authority—not that a claim is forbidden.
First-party versus third-party
A first-party claim uses your own collision or comprehensive coverage. The policy controls, and many policies limit payment to repair cost or expressly exclude reduced market value. A third-party claim seeks property damages from the person who caused the collision. Their insurer usually negotiates the claim, but the legal claim ordinarily belongs against the at-fault person.
Uninsured or underinsured motorist property-damage coverage can sit between those categories: you make the claim with your insurer, but the coverage may promise the damages you could legally recover from the uninsured driver.
Evidence that moves the claim
- The final repair invoice and every supplement, not only the first estimate.
- Photos showing structural, welded, replaced, refinished, or calibrated areas.
- The exact trim, options, mileage, pre-loss condition, and prior history.
- Comparable clean-history and accident-history vehicles from the same market.
- A written appraisal that explains its data and adjustments instead of only stating a number.
- The police report, fault decision, claim number, denial, and offer calculation.
Common reasons claims fail
Weak claims often rely only on a percentage of repair cost, a generic online valuation, or an appraisal with no comparable-market support. Prior accidents, high mileage, light cosmetic damage, incomplete repairs, a total loss, disputed fault, and a signed broad release can also change the result.
If the offer is low or the claim is denied
- Ask for the decision and calculation in writing.
- Separate a coverage denial from a disagreement about the amount. They require different responses.
- Correct factual errors in the vehicle, mileage, options, prior history, or repair record.
- Respond with market evidence tied to your actual vehicle.
- Check the policy’s appraisal clause and the state insurance department’s complaint process.
- Do not let negotiation run past a filing deadline. A complaint to a regulator usually does not pause the limitations period.
