UM vs. UIM Status
Select one:
☐ Uninsured Motorist (UM) Claim:
- The at-fault motorist was uninsured at the time of the accident within the meaning of Mo. Rev. Stat. § 379.203, in that [☐ the at-fault motorist had no bodily injury liability insurance in effect / ☐ the at-fault motorist is unknown (hit-and-run) / ☐ the at-fault motorist's insurer is insolvent / ☐ the at-fault motorist's insurer has denied coverage].

Count I
Breach of Contract (UM/UIM Benefits)

Plaintiff incorporates by reference all preceding paragraphs.
-
The Policy constitutes a valid and enforceable contract between Plaintiff and Defendant Insurer.
-
Plaintiff has performed all conditions, covenants, and obligations required under the Policy, or has been excused from performance.
-
Defendant Insurer has breached the Policy by failing and refusing to pay UM/UIM benefits owed to Plaintiff, despite Plaintiff's timely demand and proof of loss.
-
As a direct and proximate result of Defendant Insurer's breach, Plaintiff has suffered damages in a fair and reasonable amount to be proven at trial.
Count II
Vexatious Refusal to Pay (Mo. Rev. Stat. § 375.420)
-
Plaintiff incorporates by reference all preceding paragraphs.
-
Plaintiff made a claim for UM/UIM benefits under the Policy and provided all requested documentation and proof of loss.
-
Defendant Insurer's refusal to pay the claim was vexatious and without reasonable cause, in violation of Mo. Rev. Stat. § 375.420.
-
Defendant Insurer's vexatious conduct includes:
☐ Unreasonably delaying investigation of the claim
☐ Refusing to pay benefits without a reasonable basis
☐ Failing to make a reasonable settlement offer when liability is clear

☐ Future medical expenses
☐ Past lost wages/earnings
☐ Future lost wages/earning capacity

☐ Disability and disfigurement
☐ Loss of consortium (if applicable)
☐ Vexatious refusal penalty under § 375.420
☐ Reasonable attorney's fees under § 375.420
☐ Prejudgment interest
☐ Costs of suit
Stacking Allegations
-
☐ Stacking Claimed (UM): Plaintiff is insured under separate UM coverages for [IDENTIFY VEHICLES/POLICIES AND EACH UM LIMIT], with separate premiums of $[AMOUNT(S)] where applicable. Plaintiff seeks to combine the UM limits for the available coverages, for a total of $[CLAIMED LIMIT], under Mo. Rev. Stat. § 379.203. Identify the policy terms and Plaintiff's insured status; an anti-stacking clause does not by itself defeat a claim to stack separately purchased UM coverages.
-
☐ UIM Limits (Separate Analysis): For an underinsured motorist claim, the applicable UIM limit is $[APPLICABLE LIMIT] under [IDENTIFY POLICY AND TERMS]. Determine any UIM stacking question from the policy and the coverages available to Plaintiff; do not use this UIM provision to limit statutory UM coverage.
Prayer for Relief
WHEREFORE, Plaintiff respectfully prays that this Court enter judgment in favor of Plaintiff and against Defendant Insurer as follows:
- For compensatory damages in a fair and reasonable amount according to proof at trial;
- For UM/UIM policy benefits in the full amount owed under the Policy;
- For the vexatious refusal penalty under Mo. Rev. Stat. § 375.420;
- For reasonable attorney's fees under Mo. Rev. Stat. § 375.420;
- For prejudgment interest as permitted by law;
- For costs of suit incurred herein; and
- For such other and further relief as this Court deems just and proper.
DEMAND FOR JURY TRIAL
Plaintiff hereby demands a trial by jury on all issues triable of right.

State-Specific Notes — Missouri
| Topic | Detail |
|---|---|
| UM Mandatory? | Yes; required on all policies (§ 379.203) |
| UIM Mandatory? | No; optional coverage |
| Minimum UM Limits | $25,000 per person / $50,000 per accident (bodily injury only) |
| Property Damage UM | Not required by statute |
| Stacking (UM) | Separately purchased UM coverages may be combined despite an anti-stacking clause; identify the insured and each available coverage. Employer fleet coverage calls for separate review under the § 379.203 annotations to Cameron and Linderer. |
| Stacking (UIM) | Anti-stacking provisions generally upheld |
| Comparative Fault | Pure comparative fault — recovery reduced by % of fault (Gustafson v. Benda, 661 S.W.2d 11 (Mo. banc 1983); § 537.765 codifies this only for products-liability claims) |
| Statute of Limitations | UM/UIM breach-of-contract claims against the insurer are governed by the 10-year written-contract limitations period (§ 516.110), not the 5-year general/tort period in § 516.120. Edwards v. State Farm Ins. Co., 574 S.W.2d 505, 506 (Mo. App. W.D. 1978); reaffirmed in Welch v. Auto. Club Inter-Ins. Exch., No. 71668 (Mo. App. E.D. July 29, 1997). Any separate tort claim against the uninsured/underinsured motorist remains subject to the 5-year period under § 516.120. |
| Bad Faith Remedy | Vexatious refusal penalty + attorney's fees (§ 375.420) |
| Arbitration | Not mandated by statute; depends on policy terms |
| Hit-and-Run UM | Section 379.203.1 expressly provides that legal entitlement exists when the unidentified vehicle departed before identification and "whether or not physical contact was made between the uninsured motor vehicle and the insured or the insured's motor vehicle." Establish that the unidentified vehicle caused the injury; review the policy and current controlling decisions for any other applicable conditions. |
| Exhaustion (UIM) | Tortfeasor's limits must be exhausted; offset applies (§ 379.204) |
| Insurer as Stand-In | UM insurer stands in shoes of tortfeasor; insured cannot recover more than would be recovered from tortfeasor |

Legal authority

- Mo. Rev. Stat. § 379.204 (UIM construction)
- Mo. Rev. Stat. § 375.420 (vexatious refusal to pay)

Personal injury cases are brought by people who were hurt because of someone else's carelessness: car crashes, slip and falls, defective products, and more. Demand letters, settlement agreements, and court filings in these cases have to document the injuries, the medical treatment, the lost income, and the exact legal basis for holding the other side responsible. Well-prepared paperwork is what drives higher settlements and forces insurers to take the claim seriously.
