Louisiana Diminished Value Claims — The Complete Guide.

Louisiana's Explicit DV Statute + 2024 SOL Extension.

Louisiana is one of the few states with an explicit statutory provision for diminished value. La. R.S. 9:2800.17, enacted in 2010, addresses "Liability for the diminution in the value of a damaged vehicle." Combined with the foundational case Orillac v. Solomon, 765 So. 2d 1185 (La. App. 4 Cir. 2000), Louisiana's substantive DV framework is statutorily codified rather than purely case-law-based.

Critical 2024 update: Louisiana historically had the shortest tort prescriptive period in the country at 1 year. Act 423 of 2024 (House Bill 315), effective July 1, 2024, replaced Civil Code Articles 3492 and 3493 with Articles 3493.11 and 3493.12, extending the prescriptive period to 2 years for delictual actions arising on or after July 1, 2024. This includes vehicle damage and diminished value claims. Pre-July 2024 accidents remain subject to the 1-year prescription. The change brings Louisiana into closer alignment with national norms.

Louisiana Authority: Statute + Case Law + Bad-Faith Penalties

Louisiana DV law combines statutory recognition (LA R.S. 9:2800.17), foundational case law (Orillac), and a strong bad-faith statute (LA R.S. 22:1973).

Louisiana Insurers Use 17c — Orillac Doesn't.

Louisiana's controlling standard from Orillac and codified in LA R.S. 9:2800.17 is market-based. The 17c formula's mechanical multipliers don't match this. Major Louisiana insurers default to 17c. A demand letter quoting Orillac, citing LA R.S. 9:2800.17, and referencing LA R.S. 22:1973 (if the insurer is delaying without cause) puts the claim on solid Louisiana authority.

Run 17c first to anticipate the insurer's initial offer, then quantify the gap to Orillac's market-based standard:

Filing a Diminished Value Claim in Louisiana.

Louisiana's framework rests on explicit statutory recognition plus case law plus a bad-faith statute. Verify the prescriptive period based on accident date — 2 years post-July 2024, 1 year before.

1. Verify accident date for prescriptive period. Critical first step in Louisiana. Accidents on or after July 1, 2024 → 2-year prescription. Accidents before July 1, 2024 → 1-year prescription. The shorter window for pre-July 2024 accidents requires immediate action.
2. Document liability. Louisiana applies pure comparative fault under Civil Code Article 2323 — recovery reduced by fault percentage but never barred. Police report, witnesses, dashcam, traffic cameras.
3. Determine recovery path. Three options: third-party against at-fault driver's liability insurer (most common), UMPD against your own policy if the at-fault driver was uninsured (only if you don't have collision coverage; UMPD is alternative to collision in LA), or UIMPD if at-fault liability coverage is inadequate.
4. Complete repairs. Louisiana DV is calculated post-repair under Orillac and LA R.S. 9:2800.17.
5. Establish pre-accident market value. Louisiana-market comparables — New Orleans, Baton Rouge, Shreveport, Lafayette, Metairie, Lake Charles. LA's hurricane-exposed market produces unique comparable considerations (flood-history vehicles).
6. Document post-repair value. Two written dealer trade-in offers post-repair plus comparable sales of similar Louisiana vehicles with accident-history Carfax. Discount typically runs 12-22%.
7. Prepare a USPAP-compliant appraisal. The appraisal cites Orillac v. Solomon, references LA R.S. 9:2800.17 and LA R.S. 22:1973, addresses the prescriptive period applicable to your accident date, and uses Louisiana-market comparables.
8. Send a demand letter. Quote Orillac's framework. Cite LA R.S. 9:2800.17 for explicit statutory recognition. If the insurer is delaying without cause, reference LA R.S. 22:1973's bad-faith penalties. Send certified mail.
9. Allow 30 days for response. Louisiana insurers familiar with the framework typically respond within 14-30 days. Bad-faith penalties create incentive to respond promptly.
10. Small claims (City Court) for $5,000 or less; District Court above. Louisiana City Courts handle small claims up to $5,000. District Courts handle larger claims with full procedure. Be mindful of the prescriptive period.
