RE: PROFESSIONAL MALPRACTICE CLAIM - SETTLEMENT DEMAND
Claimant: [Client Full Name]
Date(s) of Negligent Services: [Date or Date Range]
Professional(s): [Professional Name(s)]
Type of Professional: [Attorney/CPA/Architect/Engineer]
Claim Number: [If assigned]
Dear [Recipient Name]:
This firm represents [Client Name] in connection with the professional malpractice committed by [Professional Name] during the provision of [legal/accounting/architectural/engineering] services. This letter constitutes formal notice of our client's claim and our demand for settlement.
I. WYOMING-SPECIFIC LEGAL FRAMEWORK
A. Governing Law
This claim is governed by Wyoming common law principles of professional negligence. In Wyoming, professional malpractice requires proof of: (1) the existence of a professional-client relationship creating a duty of care; (2) breach of that duty by failing to meet the applicable standard of care; (3) a causal connection between the breach and injury; and (4) actual damages. Meyer v. Mulligan, 889 P.2d 509 (Wyo. 1995).
B. Statute of Limitations
Licensed or Certified Professional Services: Wyo. Stat. § 1-3-107 is not limited to lawyers. It generally applies to a cause of action arising from an act, error, or omission in rendering licensed or certified professional or health-care services and uses a two-year period with the statute's specified discovery and second-year extension rules.
Other Claims: Do not automatically assign four years to every nonlegal professional claim. Determine whether the defendant and services are licensed or certified and whether § 1-3-107 applies. Only then classify any genuinely noncovered claim under § 1-3-105 or another controlling statute.
Timing under § 1-3-107(a): For covered licensed or certified professional services, the ordinary two-year period runs from the alleged act, error, or omission. A claim may be brought within two years after discovery only if the claimant establishes that the act was not reasonably discoverable during the ordinary period or was missed despite due diligence. Discovery during the second year of the ordinary period extends the filing period by six months under subsection (a)(iv). Record the act date, discovery date, and facts supporting any exception.
Representation dates: Do not extend the filing period merely because the professional relationship continued. For a covered claim, identify the alleged act, error, or omission and apply the dates and discovery conditions in Wyo. Stat. § 1-3-107(a).
Relevant Dates in This Matter:
- Date(s) of negligent services: [Date(s)]
- Date of discovery: [Date]
- Limitations period expires: [Date]
C. Comparative Negligence
Wyoming follows a modified comparative fault system under Wyo. Stat. Section 1-1-109. A claimant may recover damages if their fault is not more than 50% of the total fault of all actors. If the claimant's fault exceeds 50%, recovery is barred entirely. If fault is 50% or less, damages are reduced proportionally.
D. Standard of Care Under Wyoming Law
Under Wyoming law, a professional must exercise that degree of care, skill, and proficiency commonly exercised by ordinarily skillful, careful, and prudent professionals engaged in similar practice under similar circumstances. Kobos v. Everts, 768 P.2d 534 (Wyo. 1989).
Attorney Standard: An attorney must exercise "that degree of care, skill, diligence and knowledge commonly possessed and exercised by a reasonable, careful and prudent lawyer in the practice of law in Wyoming." Meyer v. Mulligan, 889 P.2d 509 (Wyo. 1995).
Accountant Standard: Identify the CPA's engagement and the standards applicable to it. Wyo. Stat. § 33-3-102(a)(vi)(A)-(B) distinguishes audits under the statements on auditing standards from financial-statement reviews under the statements on standards for accounting and review services. Do not assume both GAAP and auditing standards govern every CPA engagement; state the particular departure and resulting loss.
Architect/Engineer Review: Identify the design engagement, the specific work at issue, and the asserted departure from the applicable contract and professional obligations. For engineering work, check the professional's license status under Wyo. Stat. § 33-29-401 and obtain a qualified expert's assessment before asserting a negligence claim.
E. Expert Witness Requirements
Expert testimony is generally required in Wyoming professional malpractice cases to establish the standard of care, breach, and causation. Kobos v. Everts, 768 P.2d 534 (Wyo. 1989).
Exception: Expert testimony may not be required when the negligence is so grossly apparent that a layperson could determine it without expert assistance (the "common knowledge" exception).
Certification: We certify that we have retained a qualified expert who has reviewed the relevant materials and has concluded that the applicable standard of care was breached and that such breach proximately caused our client's damages.
F. Damage Caps
Wyoming does not impose statutory caps on compensatory damages in professional malpractice cases.
Punitive Damages: Wyoming allows punitive damages only in a proper case involving sufficiently outrageous, malicious, or willful-and-wanton conduct. Entitlement uses the preponderance standard. Lompe v. Sunridge Partners, LLC, 818 F.3d 1041, 1068-72 (10th Cir. 2016) (applying Wyoming law).

- Demand Letters
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.
