Dear [________________________________]:
I. INTRODUCTION AND NATURE OF DEMAND
This firm represents [________________________________] ("our client") in connection with a claim for [uninsured/underinsured] motorist benefits under South Dakota law and the above-referenced policy arising from a motor vehicle collision on [__/__/____]. This letter constitutes a formal demand for payment of the full UM/UIM policy limits of $[________________________________].
Our client's total damages substantially exceed all available coverage. Under S.D. Codified Laws § 58-11-9, every motor vehicle policy issued in South Dakota must provide uninsured motorist coverage at minimum limits of $25,000 per person / $50,000 per accident, and your policy provides limits of $[________________________________]. This coverage exists precisely to protect insureds like our client when the negligent party lacks sufficient liability insurance.
You are hereby on notice that failure to timely and fairly evaluate and pay this claim will constitute bad faith under South Dakota common law as established in Isaac v. State Farm Mut. Auto. Ins. Co., 522 N.W.2d 752 (S.D. 1994), exposing [________________________________] ("the Company") to liability for compensatory damages, consequential damages, and punitive damages under S.D. Codified Laws § 21-3-2.
II. SOUTH DAKOTA UM/UIM LEGAL FRAMEWORK
A. Mandatory UM/UIM Coverage — S.D.C.L. § 58-11-9
South Dakota requires every motor vehicle liability policy issued in this state to include uninsured motorist coverage at not less than $25,000 per person and $50,000 per accident for bodily injury. Coverage applies to the named insured, resident family members, and occupants of the insured vehicle. Hit-and-run vehicles are treated as uninsured motorists under South Dakota law. Note that UM/UIM coverage under § 58-11-9 provides bodily injury protection only — no vehicle damage component is mandated by statute.
B. UIM Offset Calculation — S.D.C.L. § 58-11-9.5
South Dakota's UIM statute employs a limits-to-limits offset approach: the available UIM benefit is calculated as the difference between the UIM policy limit and the amount actually recovered from the tortfeasor's liability carrier. The offset is applied per person, not in the aggregate. Pursuant to Gloe v. Union Insurance Co., 2005 SD 37, the carrier may not aggregate payments made to multiple claimants to reduce the per-person UIM payment owed to our client.
| Item | Amount |
|---|---|
| Client's UIM Policy Limit (per person) | $[________________________________] |
| Less: Tortfeasor's Liability Limits Paid | ($[________________________________]) |
| Maximum UIM Benefits Available | $[________________________________] |
C. Anti-Stacking Rule — S.D.C.L. § 58-11-9.9
South Dakota prohibits inter-policy stacking: UIM limits from multiple vehicles on the same policy may not be added together to increase the maximum benefit available for a single accident, regardless of the number of vehicles insured, policies in force, or persons covered. Intra-policy stacking is similarly restricted. Any policy language attempting to permit stacking beyond statutory authorization is superseded by § 58-11-9.9.
D. Comparative Fault — S.D.C.L. § 20-9-2
South Dakota applies a modified comparative fault standard with a 50% bar: a claimant whose fault equals or exceeds 50% of the total fault is barred from recovery. Where a claimant is less than 50% at fault, damages are reduced proportionally. Our client bears no comparative fault for this collision, as the evidence demonstrates.
E. Statute of Limitations
The applicable statute of limitations for this UM/UIM contract claim is six (6) years under S.D. Codified Laws § 15-2-13. The date of loss was [__/__/____], making the deadline for filing suit approximately [__/__/____]. This demand does not toll the statutory period.
III. COVERAGE ANALYSIS
A. Policy Information
| Item | Information |
|---|---|
| Named Insured | [________________________________] |
| Policy Number | [________________________________] |
| Policy Period | [__/__/____] to [__/__/____] |
| UM Coverage Limit | $[____] per person / $[____] per accident |
| UIM Coverage Limit | $[____] per person / $[____] per accident |
| Number of Vehicles on Policy | [____] |
| Stacking Status | Non-Stacked (S.D.C.L. § 58-11-9.9) |
B. Coverage Trigger
Uninsured Motorist Claim (if applicable):
The tortfeasor qualifies as an "uninsured motorist" under S.D.C.L. § 58-11-9 because:
☐ The tortfeasor carried no liability insurance at the time of the collision
☐ The tortfeasor's liability insurer has denied coverage for this collision
☐ The tortfeasor's liability insurer is insolvent
☐ The tortfeasor fled the scene and cannot be identified (hit-and-run)
☐ The tortfeasor's liability limits are below South Dakota's statutory minimum of $25,000/$50,000
Supporting documentation attached: ☐ Police report confirming no insurance ☐ Denial letter from tortfeasor's carrier ☐ NAIC insolvency notice ☐ Hit-and-run report
Underinsured Motorist Claim (if applicable):
The tortfeasor qualifies as an "underinsured motorist" under S.D.C.L. § 58-11-9.5 because:
☐ The tortfeasor's liability limits of $[________________________________] are insufficient to fully compensate our client's damages of $[________________________________]
☐ Our client has exhausted (or will exhaust upon settlement) the tortfeasor's policy limits
☐ Our client's damages exceed all available liability coverage by $[________________________________]
IV. THE COLLISION AND LIABILITY
A. Facts of the Collision
On [__/__/____], at approximately [____] a.m./p.m. Central Time, our client was [________________________________] at or near [________________________________], [________________________________] County, South Dakota.
[________________________________]
[________________________________]
[________________________________]
B. The Tortfeasor's Negligence
[________________________________] ("Tortfeasor") was negligent under South Dakota law in the following respects:
☐ Failed to maintain proper lookout as required by S.D.C.L. § 32-25-1 et seq.
☐ Failed to yield right-of-way
☐ Following too closely (S.D.C.L. § 32-26-40)
☐ Excessive speed for road and weather conditions
☐ Distracted driving (cell phone use, inattention)
☐ Failure to obey traffic control device
☐ Improper lane change
☐ Driving under the influence of alcohol or drugs (S.D.C.L. § 32-23-1)
☐ [________________________________]
C. Evidence of Liability
Police Report: [________________________________] Traffic Crash Report No. [________________________________], dated [__/__/____], prepared by Officer [________________________________] of [________________________________] law enforcement. ☐ Tortfeasor cited ☐ Tortfeasor at fault per narrative
Witness Statements: [____] independent witnesses confirmed the Tortfeasor's negligence. Names and contact information available upon request.
Physical Evidence: ☐ Skid marks ☐ Vehicle damage consistent with described impact ☐ Debris field ☐ Traffic camera footage ☐ Dashcam video
Expert Analysis: [________________________________] (accident reconstruction specialist) has concluded: [________________________________]
D. Our Client's Comparative Fault
Under S.D.C.L. § 20-9-2, our client's fault is zero percent (0%). The physical evidence, eyewitness accounts, and police report uniformly establish that the Tortfeasor was solely responsible for this collision. There are no facts supporting a comparative fault argument against our client, and any attempt to assert one would be pretextual and in bad faith.

Please provide written consent or denial within [____] calendar days of this letter.

| UIM BENEFITS DEMANDED | $[________________________________] |
Our client's uncompensated damages of $[________________________________] vastly exceed the available UIM limits. This is a clear policy limits case under South Dakota law.
B. Formal Demand
We hereby demand payment of the full UIM/UM policy limits of $[________________________________] within [____] calendar days of the date of this letter.
IX. SOUTH DAKOTA BAD FAITH WARNING
The Company owes our client — its own insured — the duty of good faith and fair dealing. Under South Dakota law, bad faith is an intentional tort requiring proof that: (1) there was no reasonable basis to deny, delay, or underpay the claim; and (2) the insurer knew of, or recklessly disregarded, the lack of a reasonable basis for its conduct. Isaac v. State Farm Mut. Auto. Ins. Co., 522 N.W.2d 752, 759 (S.D. 1994). An insurer's unreasonable delay in investigating, evaluating, or paying a valid claim independently constitutes bad faith. Champion v. United States Fidelity & Guaranty Co., 399 N.W.2d 320, 322 (S.D. 1987).
A. Prohibited Conduct Under S.D.C.L. § 58-33-67
The Company must not engage in the following unfair claims practices, each of which independently triggers regulatory and civil liability:
☐ Failing to acknowledge and begin investigation within 30 days of receiving notice of this claim
☐ Misrepresenting policy provisions relating to UM/UIM coverage
☐ Refusing to pay a valid claim without conducting a reasonable investigation
☐ Failing to provide a written explanation for any denial or compromise offer
☐ Compelling litigation by offering substantially less than the claim's documented value
☐ Attempting to settle for less than a reasonable person would expect to be entitled to receive
B. Attorney's Fees Under S.D.C.L. § 58-12-3
If the Company refuses to pay the full UM/UIM benefits owed and that refusal is vexatious or without reasonable cause, South Dakota courts will award our client a reasonable attorney's fee as part of costs. Brooks v. Milbank Ins. Co., 2000 SD 80. Given the clarity of coverage and liability here, any refusal to pay policy limits would be vexatious.
C. Punitive Damages Under S.D.C.L. § 21-3-2
South Dakota imposes no statutory cap on punitive damages. Where an insurer acts with malice, oppression, or fraud in denying a legitimate claim, punitive damages may be awarded by the jury in addition to compensatory damages. Isaac, 522 N.W.2d at 761 (affirming $20,000 punitive award against State Farm). The Company's exposure in this regard is significant and uncapped.
X. ARBITRATION
A. Policy Arbitration Clause
The policy ☐ contains / ☐ does not contain a binding arbitration clause for UM/UIM disputes.
[If applicable: The policy provides for arbitration of UM/UIM disputes at: [________________________________]. Applicable arbitration rules: [________________________________].]
B. Notice of Intent to Arbitrate
If the Company declines this demand, consider this letter formal notice of our client's intent to invoke arbitration (if applicable under the policy) or to file suit in [________________________________] County, South Dakota.
XI. RESPONSE DEADLINE AND CONSEQUENCES
THIS DEMAND EXPIRES AT 5:00 P.M. CENTRAL TIME ON [__/__/____].
If the Company fails to tender the full UM/UIM policy limits by the deadline:
-
We will file suit in South Dakota [Circuit/Federal District] Court seeking all available damages, including bad faith tort damages, punitive damages under S.D.C.L. § 21-3-2, and attorney's fees under S.D.C.L. § 58-12-3.
-
We will file a formal complaint with the South Dakota Division of Insurance, 124 S. Euclid Avenue, 2nd Floor, Pierre, SD 57501 | Phone: (605) 773-3563 | dlr.sd.gov/insurance, documenting the Company's violations of S.D.C.L. § 58-33-67.
-
We will invoke the policy arbitration process (if applicable).
-
This demand will be withdrawn as a settlement offer, and no further settlement offer will be made at or near policy limits.
XII. DOCUMENT PRESERVATION NOTICE
This letter constitutes formal notice that the Company must immediately preserve and not destroy, overwrite, or otherwise alter any documents, electronically stored information, or tangible materials related to this claim, including:
- Complete claim file in all versions and drafts
- All adjuster notes, activity logs, and reserve documentation
- All internal communications and emails regarding this claim
- Claim handling guidelines and training materials
- All photographs, inspection reports, and expert evaluations

XIII. CONCLUSION
This claim presents clear UM/UIM coverage, unambiguous liability, documented severe injuries, and total damages far exceeding policy limits.

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
