Every fact below is quoted from the regulation or statute it cites. Where the primary sources do not settle a point, it is marked and left open rather than filled in — which is itself worth knowing before you argue it.
What is not yet confirmed here
- What the insurer must show you partly verifiedRecorded as an absence after reading the section for a delivery duty.
- Sales tax partly verifiedTwo facts pull in opposite directions here.
The audit leaves what the insurer must show you and sales tax out of the headline range rather than guessing.
When a car counts as a total loss
“Was damaged during a year that is no more than six years after the manufacturer's model year designation for such vehicle to the extent that the total cost of repairs to rebuild or reconstruct the vehicle to its condition immediately before it was damaged for legal operation on the roads or highways exceeds eighty percent of the fair market value of the vehicle immediately preceding the time it was damaged”
The six-year limit is the part usually left out when Missouri is described as an '80 percent state'. For an older car the salvage definition does not bite at all, so the 80 percent figure is not a general Missouri total-loss threshold. This is a TITLING definition; Missouri's insurance regulation sets no threshold compelling an insurer to declare a total loss, so the decision remains the insurer's under the policy.

How the settlement must be valued
“The insurer shall not use as a basis for cash settlement with a first-party claimant an amount which is less than the amount which the insurer would pay if repairs were made, other than in total loss situations, unless the amount is agreed to by the insured.”
Read the exception carefully, because it cuts against the claimant: the repair-cost floor expressly does NOT apply in total loss situations. So the provision that looks protective on first reading is the one that leaves a Missouri total loss without a methodology. The absence is the verified finding — 20 CSR 100-1.050 was read for a comparable-vehicle method, a market area and a fee rule and has none of them.

How comparables must be chosen
“When the amount claimed is reduced because of betterment or depreciation, all information for the reduction shall be contained in the claim file. These reductions shall be itemized and appropriate in amount.”
The quoted provision, 20 CSR 100-1.050(2)(E), is the nearest thing Missouri has to a comparables constraint and it is the practical lever here: a betterment or depreciation reduction must be itemized, appropriate in amount, and fully documented in the claim file. Missouri's regulator has publicly cautioned that relying on valuation software alone does not discharge an insurer's duty under § 375.1007, as that guidance was not retrieved.

What the insurer must show you
partly verified“all information for the reduction shall be contained in the claim file. These reductions shall be itemized and appropriate in amount.”
Recorded as an absence after reading the section for a delivery duty. The material therefore exists in the file by regulation but is not owed to you automatically — so ask for it in writing and date the request, relying on the prompt-fair-and-equitable duty in § 375.1007 rather than on a valuation-disclosure rule, because Missouri has none.

Sales tax
partly verified“the director shall permit the amount of the insurance proceeds plus any owner's deductible obligation, as certified by the insurance company, to be a credit against the purchase price of another motor vehicle”
Two facts pull in opposite directions here. No Missouri statute or regulation makes the insurer pay sales tax; the Revised Statutes were searched and the only matches were the salvage-title statute and the tax code. But § 144.027 means a Missouri owner who replaces the car within 180 days of the insurance payment owes sales tax only on the amount above the proceeds plus deductible, so the insurer will say the tax is not a loss at all. The reply is that the credit runs only to a replacement bought in time, and an owner who cannot replace within 180 days, or replaces for more, still bears it. Ask the insurer for the certified proceeds statement the statute requires.

Title and registration fees
confirmed: no ruleThe settlement regulation is silent on fees, and the Revised Statutes of Missouri was searched for a total-loss fee requirement; the only matches were the salvage-title statute (§ 301.213) and the tax code's replacement credit (§ 144.027). Some policy forms include these fees as a matter of contract, which is a policy question rather than a state requirement.

Appraisal clause
confirmed: no rule20 CSR 100-1.050 was retrieved and read and contains no mention of appraisal or an umpire. The remainder of 20 CSR 100 chapter 1 and Mo. Rev. Stat. ch. 375 were not retrieved section by section.

Claim-handling deadlines
“Within fifteen (15) working days after the submission of all forms necessary to establish the nature and extent of any claim, the first-party claimant shall be advised of the acceptance or denial.”
The clock runs in WORKING days, and — importantly — it starts only once ALL necessary forms have been submitted, which is a start point the insurer has considerable influence over. Pin down in writing the date the last requested item was sent. No acknowledgement clock or payment clock was located in this section, and the wider chapter 20 CSR 100-1 was not read section by section, so those are recorded as absent from this rule rather than absent from Missouri law.

Unfair claims practices law
“Within fifteen (15) working days after the submission of all forms necessary to establish the nature and extent of any claim, the first-party claimant shall be advised of the acceptance or denial.”
The quote is from the regulation; § 375.1007 itself was not read directly, so the statutory citation is recorded without a quote. The regulation's own framing is that it interprets § 375.1007(3) and (4), which is why an argument in Missouri is usually pitched at the statutory duty of prompt, fair and equitable settlement with the regulation supplying the specifics.

Time limit to sue your own insurer
“An action upon any writing, whether sealed or unsealed, for”
TEN years on an action upon a writing for the payment of money — the longest period in the ledger alongside Illinois, and more than three times Maryland's or North Carolina's. The quoted fragment is the opening of subdivision (1) as retrieved. Check the policy for a shorter suit-limitation clause: a ten-year statutory period is exactly the situation in which a contractual clause makes the most difference.

Where to file a complaint
“The Division provides consumer information and investigates consumer complaints against insurance companies and producers for most types of insurance.”
The Division forwards the complaint to the insurer and requires a response, then reviews it for compliance with Missouri insurance law. It states it cannot establish the value of a claim, so the packet should lead with the specific rule or policy term at issue. Online form (English/Spanish) linked from this page; fax 573-526-4898; hotline 800-726-7390.

Open questions on this row (4)
These are the things we could not settle from primary sources. They are published rather than hidden, because a reader arguing this rule should know where it thins out.
- Not yet read: the remainder of 20 CSR 100 chapter 1 for an acknowledgement clock and a payment clock. 20 CSR 100-1.050 supplies only the 15-working-day decision rule, and it would be wrong to conclude from that alone that Missouri has no other deadlines.
- Not yet read at the source: Mo. Rev. Stat. § 375.1007 to capture a verbatim quote for the statute the regulation interprets, in particular subsections (3) and (4).
- Not yet read at the source: the Missouri DCI guidance reported to warn insurers that valuation software alone does not discharge the duty under § 375.1007. If it exists as a bulletin, it is directly on point for a software-generated valuation and belongs in “how comparables must be chosen”.
- Confirm whether Missouri enforces contractual suit-limitation clauses shorter than the ten years in § 516.110(1).
