Before relying on a collision estimate in Louisiana, check which crash parts are intended and where the written non-OEM disclosure appears. An unexplained abbreviation beside a part is not the same thing as the notice attached to the insured’s estimate copy. A later invoice answers a different question: what the shop says it supplied.
For Monroe and Ouachita Parish readers, the relevant requirements come from Louisiana law. They do not establish that a particular replacement part is equivalent, covered by a policy or appropriate for a private vehicle.
First, identify what the crash-part rule covers
R.S. 51:2422 defines aftermarket crash parts around replacement nonmechanical exterior sheet-metal or plastic parts, including inner and outer panels. Its non-OEM definition concerns parts not made for or by the vehicle manufacturer.
Do not expand that definition to every mechanical or safety component on a repair estimate. Ask the estimator to explain the actual part, its stated origin and condition, and the rule being applied. If the classification remains unclear, record that uncertainty rather than assigning it yourself.
Written advice and the estimate attachment do different jobs
R.S. 51:2424 first requires written advice to the insured for the insurer’s specified non-OEM use or the repair facility/installer’s use described in subsection A. When an insurer intends non-OEM aftermarket crash parts, subsection B additionally requires:
- the written estimate to identify each such part clearly;
- the prescribed disclosure, in 10-point type or larger, on or attached to the insured’s copy of the estimate.
The statutory notice identifies the non-vehicle-manufacturer source and the replacement-part manufacturer or distributor as the source of applicable warranties. Read the exact required wording in the linked law; this article does not supply a substitute legal form. A notice is not a finding about the part’s quality, and these provisions are not described here as a signed-consent requirement.
The LDI accident brochure, marked Rev. 02/2025, also advises asking for a written estimate and a contact provision for costs exceeding it. That is consumer guidance; do not turn the brochure into proof of the terms agreed for a particular repair.
Three paperwork situations worth distinguishing
These are hypothetical document descriptions, not findings about an actual shop:
| What the reader has | What remains unanswered | A precise request |
|---|---|---|
| An estimate with an unexplained part abbreviation | What does the label mean, and which intended part does it identify? | Ask the estimator to explain the line and provide the complete estimate and disclosure attachment. |
| A disclosure page but no identifiable estimate version | Which intended parts and estimate does the notice accompany? | Request the matching dated/versioned estimate rather than attaching the notice to a different proposal. |
| An invoice whose part description differs from the last estimate | Was the planned part changed, and what record explains that change? | Ask for the revised part line and associated communications; do not assume the earlier notice describes the supplied part. |
Keep the original wording and version of each document. LSL’s comparison identifies questions; it is not a compliance verdict or permission to use a part.
Shop choice does not settle the parts or payment question
The current shop-choice subsection, R.S. 22:1892(D), restricts an insurer from requiring a particular repair shop when making claim-related payment. It also addresses recommendations without notice that the service is optional, and coercion.
That distinction matters when a recommendation sounds mandatory. Ask the insurer to clarify its recommendation and keep the response. Choosing a shop does not, on its own, establish coverage, a particular part’s price or a warranty result; those are separate questions. This guide does not evaluate a private insurer’s conduct.
Compare intended parts with supplied parts
The later invoice required by R.S. 32:535.1 identifies supplied parts and their stated origin/condition along with work and vehicle information. Compare those descriptions with the estimate and any changes. The invoice does not replace the pre-repair disclosure, and neither document proves installation or vehicle safety.
For estimate changes and invoice fields, use the separate Louisiana repair-bill comparison. If an unanswered issue leads to a complaint, the agency-preparation guide distinguishes submission records from a finding or remedy.
Review note
LSL read both pages of the LDI brochure as text and rendered images on September 12, compared the complete crash-part definition/disclosure and invoice sections, and checked the complete shop-choice subsection. We did not review every provision of the lengthy insurance statute or determine a private claim. The brochure supplies a month-only revision label, so its former exact February 1 publication date has been removed. No shop, insurer, manufacturer or vehicle was investigated or contacted.
