Dear [ADJUSTER_NAME]:
I. INTRODUCTION AND NATURE OF DEMAND
This firm represents [CLIENT_NAME] ("our client") in connection with a claim for [UNINSURED/UNDERINSURED] motorist benefits arising from a motor vehicle collision that occurred on [DATE_OF_LOSS]. This letter constitutes a formal demand for payment of the full UM/UIM policy limits of [UM_UIM_LIMITS].
Our client's damages far exceed the available UM/UIM coverage. The tortfeasor [WAS UNINSURED / HAD INADEQUATE LIABILITY COVERAGE OF ONLY [TORTFEASOR_LIMITS]], leaving our client with no adequate remedy against the at-fault driver. This is precisely the scenario for which UM/UIM coverage exists - to protect your insured when the negligent party lacks sufficient coverage.
After [NUMBER] years of practicing personal injury and insurance law, I am confident in stating that liability in this matter is clear, our client's injuries are well-documented and severe, and the full policy limits represent fair compensation for a claim worth substantially more.
II. POLICY INFORMATION AND COVERAGE

| Item | Information |
|---|---|
| Named Insured | [NAMED_INSURED] |
| Policy Number | [POLICY_NUMBER] |
| Policy Period | [POLICY_PERIOD_START] to [POLICY_PERIOD_END] |

B. Coverage Trigger Analysis
For Uninsured Motorist (UM) Claims:
The tortfeasor qualifies as an "uninsured motorist" under the policy because:
☐ The tortfeasor had no liability insurance at the time of the collision
☐ The tortfeasor's insurer has denied coverage
☐ The tortfeasor's insurer is insolvent
☐ The tortfeasor was a hit-and-run driver who cannot be identified
☐ The tortfeasor's insurance limits are less than the state minimum requirements
For Underinsured Motorist (UIM) Claims:
The tortfeasor qualifies as an "underinsured motorist" under the policy because:
☐ The tortfeasor's liability limits of [TORTFEASOR_LIMITS] are insufficient to compensate our client for damages sustained
☐ Our client has exhausted the tortfeasor's policy limits
☐ Our client's damages exceed the total of the tortfeasor's limits plus our client's UIM limits
C. Stacking Analysis (If Applicable)
[STATE] [PERMITS/PROHIBITS/LIMITS] the stacking of UM/UIM coverages. [IF STACKING APPLIES]:
Under [STATE] law and the terms of the policy, our client is entitled to stack UM/UIM coverage as follows:
| Vehicle | UM/UIM Limit | Stacking Permitted |

| Total Stacked Limit | [TOTAL_STACKED] |

VI. SETTLEMENT WITH TORTFEASOR'S INSURER
A. Settlement Reached
We have reached a settlement with the tortfeasor's liability carrier, [TORTFEASOR_CARRIER], for the tortfeasor's policy limits of $[TORTFEASOR_LIMITS].
B. Consent to Settle / Preservation of Subrogation Rights
IMPORTANT: Pursuant to [STATE] law and the terms of the UM/UIM policy, we hereby request your consent to settle with the tortfeasor's carrier before finalizing that settlement.
Under [CITE_STATE_LAW_OR_POLICY_PROVISION], the UM/UIM carrier is entitled to:
☐ Subrogate against the tortfeasor for amounts paid
☐ Receive notice before insured settles with tortfeasor
☐ Approve or reject proposed settlement with tortfeasor
☐ Substitute its payment for tortfeasor's limits and pursue tortfeasor directly
We request that you provide written consent to the proposed settlement within [NUMBER] days. Your failure to respond will be deemed consent under [CITE_AUTHORITY].
Alternatively, if [CARRIER_SHORT_NAME] wishes to preserve subrogation rights, please advise immediately and [ADVANCE_THE_TORTFEASOR'S_LIMITS/SUBSTITUTE_PAYMENT].
VII. DEMAND FOR UM/UIM BENEFITS
A. Calculation of UIM Benefits Due
| Item | Amount |
|---|---|
| Total Damages | $[TOTAL_DAMAGES] |
| Less: Tortfeasor's Limits | ($[TORTFEASOR_LIMITS]) |
| Underinsured Damages | $[UNDERINSURED_DAMAGES] |
| Available UIM Limits | $[UIM_LIMITS] |
| UIM BENEFITS DEMANDED | $[UIM_DEMAND] |
B. Policy Limits Demand
We hereby demand payment of the full UM/UIM policy limits of $[UM_UIM_LIMITS].
Our client's damages of $[TOTAL_DAMAGES] vastly exceed the combined coverage available from both the tortfeasor's carrier ($[TORTFEASOR_LIMITS]) and your UM/UIM policy ($[UM_UIM_LIMITS]). Accordingly, this is a clear policy limits case.
C. Terms of Settlement
Upon receipt of payment, we will provide:
☐ Full release of [CARRIER_SHORT_NAME] from all UM/UIM claims arising from this loss
☐ Preservation of [CARRIER_SHORT_NAME]'s subrogation rights against the tortfeasor
☐ Cooperation in any subrogation action
☐ [ADDITIONAL_TERMS]
VIII. RESPONSE DEADLINE
This demand expires at 5:00 p.m. [TIME_ZONE] on [RESPONSE_DEADLINE].
This deadline provides [CARRIER_SHORT_NAME] [NUMBER] days to evaluate this demand. We have provided complete documentation of liability, injuries, treatment, and damages. No additional information should be required.
A. Consequences of Non-Response
If [CARRIER_SHORT_NAME] fails to accept this demand by the deadline, we will:
-
Invoke arbitration (if required by policy) or file suit seeking:
- Full UM/UIM policy limits
- Bad faith damages (if applicable under [STATE] law)
- Statutory penalties and interest
- Attorney's fees and costs -
Report the claim handling to the [STATE] Department of Insurance for investigation of potential unfair claims practices.
-
Seek discovery into [CARRIER_SHORT_NAME]'s claims handling practices, including:
- Similar UM/UIM claims files
- Training materials
- Adjuster performance metrics
- Reserve and settlement authority documentation
B. Bad Faith Warning
[CARRIER_SHORT_NAME] owes our client, its own insured, the same duties of good faith and fair dealing that apply to any first-party insurance claim. Under [STATE] law, [CITE_FIRST_PARTY_BAD_FAITH_AUTHORITY], an insurer acts in bad faith when it [STATE_BAD_FAITH_STANDARD].
The liability in this matter is clear. The damages far exceed the available coverage. Any attempt to deny, delay, or lowball this claim will be met with a bad faith action seeking compensatory damages, punitive damages, and attorney's fees.
IX. ARBITRATION CONSIDERATIONS
A. Policy Arbitration Clause
The policy [CONTAINS/DOES_NOT_CONTAIN] an arbitration clause for UM/UIM disputes. [IF APPLICABLE]:
The arbitration clause provides: "[QUOTE_ARBITRATION_CLAUSE]"
B. Arbitration Demand (Alternative)
If [CARRIER_SHORT_NAME] fails to accept this demand, consider this letter as notice of our intent to invoke arbitration. We will:
☐ Select [ARBITRATOR_NAME/TO_BE_DETERMINED] as our party-appointed arbitrator
☐ Request that the arbitrators be selected pursuant to [POLICY_PROVISION/STATE_LAW]
☐ Seek an award of the full policy limits plus [ADDITIONAL_RELIEF_IF_PERMITTED]
C. Waiver of Arbitration
Alternatively, if both parties agree, we are willing to waive arbitration and proceed directly to [LITIGATION/MEDIATION] to resolve this matter.
X. ENCLOSED DOCUMENTATION
The following documents are enclosed to support this demand:
Liability Documentation:
☐ Police Traffic Crash Report
☐ Witness statements
☐ Photographs of accident scene
☐ Photographs of vehicle damage
☐ Accident reconstruction report
☐ [OTHER_LIABILITY_DOCUMENTS]
Medical Documentation:

☐ UM/UIM coverage provisions
☐ Consent to settle correspondence
☐ Tortfeasor's policy information
☐ [OTHER_INSURANCE_DOCUMENTS]
XI. CONCLUSION
This claim presents clear liability, severe and well-documented injuries, and damages far exceeding the available coverage. [CARRIER_SHORT_NAME] has an opportunity to resolve this matter fairly by paying the policy limits to its own insured.
Our client purchased UM/UIM coverage precisely for situations like this - to provide protection when a negligent driver lacks adequate coverage. [CARRIER_SHORT_NAME] should honor that coverage promptly and in good faith.
We look forward to your prompt response.
Respectfully submitted,

About This Template
A demand letter is a formal written request to fix a problem or pay what is owed, sent before anyone files a lawsuit. It gives the other side a real chance to settle, creates a record of your attempt to resolve things, and in many cases (unpaid debts, insurance claims, broken contracts) starts a legally required response window. A well-written demand letter lays out what happened, what you want, and a deadline to act, which is often enough to get results without ever going to court.
Important Notice
