RE: SETTLEMENT DEMAND - MOTOR VEHICLE COLLISION
Our Client: [________________________________] (hereinafter "Claimant")
Date of Loss: [__/__/____]
Location of Accident: [________________________________]
Your Insured: [________________________________] (hereinafter "Tortfeasor")

Dear [________________________________]:

This firm represents [________________________________] (hereinafter "Claimant") in connection with personal injuries and damages sustained in a motor vehicle collision that occurred on [__/__/____] in [________________________________] County, Wyoming. This letter constitutes a formal demand for settlement of our client's claims arising from the negligence of your insured, [________________________________].

If and to the extent this demand constitutes compromise negotiations concerning a claim disputed as to validity or amount, W.R.E. 408 may limit specified uses of the negotiations. It does not itself create confidentiality or privilege and may permit use for another purpose. We remind you that Wyoming recognizes a tort cause of action for the breach of the duty of good faith and fair dealing owed by an insurer, McCullough v. Golden Rule Ins. Co., 789 P.2d 855 (Wyo. 1990), and that the conduct proscribed by Wyoming's Unfair Claims Settlement Practices statute, Wyo. Stat. Ann. § 26-13-124, may support such a claim. Failure to evaluate and respond to this demand in good faith may expose your company to extracontractual liability.


I. WYOMING LEGAL FRAMEWORK

A. Modified Comparative Fault (50% Bar) - Wyo. Stat. Ann. § 1-1-109

Wyoming follows a modified comparative fault system under Wyo. Stat. Ann. § 1-1-109(b), which provides:

"Contributory fault shall not bar a recovery in an action by any claimant or the claimant's legal representative to recover damages for wrongful death or injury to person or property, if the contributory fault of the claimant is not more than fifty percent (50%) of the total fault of all actors. Any damages allowed shall be diminished in proportion to the amount of fault attributed to the claimant."

Under this statute, a claimant is barred from recovery if the claimant's contributory fault is more than 50% of the total fault of all actors. If the claimant's fault is 50% or less, the claimant may recover, with damages reduced in proportion to the claimant's percentage of fault. The trier of fact apportions fault among all "actors," defined to include any person whose fault was a proximate cause of the injury, whether or not a party to the litigation. Wyo. Stat. Ann. § 1-1-109(a)(i).

In the present case, your insured bears 100% of the fault for this collision. Our client was free of all contributory fault.

B. Several Liability - Wyo. Stat. Ann. § 1-1-109(e)

Under Wyo. Stat. Ann. § 1-1-109(e), each defendant is liable for that defendant's proportion of the total fault determined under subsection (c). Evaluate any separately supported vicarious or other liability theory before making a categorical statement about allocation.

C. Statute of Limitations - Wyo. Stat. Ann. § 1-3-105

Wyo. Stat. Ann. § 1-3-105(a)(iv)(C) gives four years after accrual only for a noncontract injury to rights not otherwise enumerated. The section does not make the collision date the accrual date. Classify every claim and determine accrual under current controlling authority before stating a deadline: [__/__/____].

D. Mandatory Liability Insurance - Wyo. Stat. Ann. § 31-9-405

Wyoming requires every motor vehicle operated on its highways to be covered by liability insurance meeting the following minimum limits under Wyo. Stat. Ann. § 31-9-405(b)(ii):

Coverage Type Minimum Limit
Bodily Injury - Per Person $25,000
Bodily Injury - Per Accident $50,000
Property Damage - Per Accident $20,000

Under Wyo. Stat. Ann. § 31-9-405(f)(i), the liability of the insurer becomes absolute when injury or damage covered by the policy occurs, and the policy may not thereafter be cancelled or annulled as to that liability by any agreement between the insurer and the insured.

E. Uninsured/Underinsured Motorist Coverage - Wyo. Stat. Ann. § 31-10-101 et seq.

Under Wyo. Stat. Ann. § 31-10-101, uninsured-motorist bodily-injury coverage must be provided in qualifying motor vehicle liability policies, subject to rejection, at no less than the statutory financial-responsibility limits. Wyoming does not statutorily mandate UIM coverage; any UIM protection and trigger arise from the policy.

F. Bad Faith and Unfair Claims Settlement Practices

Wyoming recognizes a tort cause of action for an insurer's breach of the implied duty of good faith and fair dealing. McCullough v. Golden Rule Ins. Co., 789 P.2d 855 (Wyo. 1990). Under McCullough, an insurer that denies or fails to settle a claim without a reasonable basis—where the claim is not "fairly debatable"—may be liable in tort for extracontractual damages.

Wyoming's Unfair Claims Settlement Practices statute, Wyo. Stat. Ann. § 26-13-124, prohibits, among other things, "[n]ot attempting in good faith to effectuate prompt, fair and equitable settlements of claims in which liability has become reasonably clear" and "[c]ompelling insureds to institute litigation to recover amounts due under an insurance policy by offering substantially less than the amounts ultimately recovered." While § 26-13-124 itself does not create a private right of action (Herrig v. Herrig, 844 P.2d 487 (Wyo. 1992)), the conduct it proscribes is regularly offered as evidence supporting a common-law bad faith claim. We expressly reserve all such rights and remedies.

G. Collateral Source Rule

Identify the medical bills, amounts paid, reimbursement obligations, and any asserted offsets. Do not state an admissibility or recovery rule based solely on the existence of insurance; confirm the controlling Wyoming authority for the particular evidence and claim before using this demand in litigation.

III. LIABILITY ANALYSIS

A. Negligence of Your Insured

Under Wyoming law, the elements of a negligence claim are: (1) a duty of care, (2) a breach of that duty, (3) the breach proximately caused injury, and (4) damages. See Andersen v. Two Dot Ranch, Inc., 2002 WY 105, 49 P.3d 1011 (Wyo. 2002).

Your insured breached the duty of care by:

☐ Failing to maintain control of the vehicle
☐ Operating a vehicle in a careless or reckless manner (Wyo. Stat. Ann. § 31-5-229)
☐ Failing to maintain a proper lookout
☐ Following too closely (Wyo. Stat. Ann. § 31-5-210)
☐ Failing to yield the right of way (Wyo. Stat. Ann. § 31-5-201 et seq.)
☐ Operating a motor vehicle while distracted / texting (Wyo. Stat. Ann. § 31-5-237)
☐ Driving while under the influence (Wyo. Stat. Ann. § 31-5-233)
☐ Exceeding the posted speed limit / driving too fast for conditions (Wyo. Stat. Ann. § 31-5-301)
☐ Failing to obey a traffic control device (Wyo. Stat. Ann. § 31-5-205)
☐ [________________________________] [other negligent conduct]

B. Negligence Per Se / Safety-Statute Violation

A violation of a Wyoming traffic statute enacted for the safety of the public is evidence of negligence and may establish a breach of the standard of care.

C. Proximate Causation

Your insured's negligence was the direct and proximate cause of our client's injuries. But for the negligent conduct, this collision would not have occurred.

D. Allocation of Fault

Your insured bears 100% of the fault for this collision. Our client bears 0% contributory fault. Accordingly, no reduction under Wyo. Stat. Ann. § 1-1-109 applies.

Pain and Suffering Valuation: Based on the severity, duration, and permanence of our client's injuries, we value pain and suffering at $[________].

VI. DEMAND FOR SETTLEMENT

Based upon the foregoing, we demand settlement in the total amount of:

$[________________________________]

This demand is open for thirty (30) days, expiring on [__/__/____]. If we do not receive a meaningful response or acceptable offer by that date, we will file a civil complaint in the appropriate Wyoming District Court without further notice.

This demand covers all claims including:

☐ Personal injury claims
☐ Property damage claims
☐ Loss of consortium (if applicable)
☐ All past, present, and future damages

[OPTIONAL - POLICY LIMITS DEMAND] The damages set forth above substantially exceed the available liability coverage. We therefore demand tender of the full applicable policy limits of $[________]. This is a time-limited demand to settle within policy limits, open for [____] days. We request immediate written confirmation of all applicable liability, umbrella, and excess coverage. An insurer that, without a reasonable basis, fails to settle within policy limits where liability is reasonably clear and the claim is not fairly debatable exposes itself to extracontractual (bad faith) liability under McCullough v. Golden Rule Ins. Co., and all such rights are expressly reserved.


VII. SETTLEMENT NEGOTIATION PROVISIONS

A. Good Faith Claims Handling

Wyoming imposes a duty of good faith and fair dealing on insurers. The unreasonable failure to evaluate and pay a legitimate claim that is not fairly debatable may give rise to bad faith liability under McCullough. Wyoming also requires property and casualty insurers to accept or reject claims and pay within 45 days of receipt of the claim and supporting bills. Wyo. Stat. Ann. § 26-15-124(b).

B. Policy Limits Disclosure

We request immediate written confirmation of:

☐ The liability coverage limits
☐ Any umbrella or excess policies
☐ Whether coverage is disputed
☐ UM/UIM coverage limits on all applicable policies

C. Reservation of Rights

This demand is without prejudice to all rights, including bad faith claims under McCullough, and all other available remedies.


VIII. LITIGATION WARNING

Should settlement fail, we will file suit in the District Court for [________________________________] County, Wyoming. We will pursue full compensatory damages, prejudgment interest where allowable, court costs, and all available relief.


IX. MEDICAL RECORDS AUTHORIZATION

Enclosed is a HIPAA-compliant authorization (45 C.F.R. § 164.508).

I, [________________________________], authorize the following providers to release records related to the collision on [__/__/____] to [________________________________] [Insurance Company]:

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.
