RE: PROFESSIONAL MALPRACTICE CLAIM - SETTLEMENT DEMAND
Claimant: [Client Full Name]
Date(s) of Negligent Service: [Date or Date Range]
Professional(s): [Professional Name(s) and License Type]
Matter/Project: [Description]
Claim Number: [If assigned]
Dear [Recipient Name]:
This firm represents [Client Name] in connection with the professional malpractice committed by [Professional/Firm Name] in [his/her/their] provision of [type of professional services] services. This letter constitutes formal notice of our client's claim and our demand for settlement.
I. MISSOURI-SPECIFIC LEGAL FRAMEWORK
A. Governing Law
Professional malpractice claims in Missouri require attention to the profession involved, the claimed breach, and the resulting harm. Identify any governing statute or profession-specific rule before stating the legal standard.
B. Statute of Limitations
Claim-specific period and accrual: For a claim governed by Mo. Rev. Stat. § 516.120, the period is five (5) years. Section 516.100 measures accrual from when resulting damage is sustained and capable of ascertainment, rather than automatically from the act or omission. Identify the particular cause of action and any different applicable period before calculating a deadline. The statute does not state a general actual-discovery trigger.
Relevant Dates in This Matter:
- Date(s) of negligent services: [Date(s)]
- Date resulting damage was sustained and capable of ascertainment: [Date and supporting facts]
- Applicable limitations period and calculated deadline: [Period, date, and authority]
C. Comparative Negligence
Mo. Rev. Stat. § 537.765 addresses comparative fault in products liability claims; it is not the authority for this professional-malpractice demand. Assess any comparative-fault defense under the law governing the particular claim before asserting a reduction or recovery amount.
D. Standard of Care Under Missouri Law
Identify the standard applicable to the defendant's profession and the particular services at issue. For technical matters outside ordinary experience, obtain qualified expert support. See Eisenmann v. Podhorn, No. ED103171 (Mo. Ct. App. May 9, 2017).
Key Case Law:
- Attorneys: Must exercise "that degree of skill and diligence which lawyers of ordinary skill and capacity commonly possess and exercise." Williams v. Preman, 911 S.W.2d 288 (Mo. Ct. App. 1995).
- Accountants: Identify the services the accountant actually undertook and the standards applicable to that engagement. Mo. Rev. Stat. § 326.256.1(2) distinguishes audits, reviews, and other attest services governed by different professional standards; do not apply one GAAP/GAAS formula to every service.
- Engineers/Architects: Must exercise the same degree of care and skill as ordinarily employed by members of the profession. Cori v. Burroughs Mach., Ltd., 10 S.W.3d 503 (Mo. Ct. App. 1999).
E. Expert Witness Requirements
Expert testimony is generally required in professional malpractice cases to establish:
- The applicable standard of care;
- That the defendant breached that standard; and
- That the breach proximately caused the plaintiff's damages.
Eisenmann v. Podhorn, No. ED103171 (Mo. Ct. App. May 9, 2017), explains that expert testimony is required where professional-negligence issues fall outside ordinary lay knowledge.
Exception: Expert testimony is not required when the alleged negligence is so obvious that laypeople can determine it without expert guidance.
Certification: We have retained a qualified expert who has reviewed the relevant documents and has concluded that the applicable standard of care was breached and that such breach proximately caused our client's damages.
F. Damage Caps
Missouri does not impose statutory caps on damages in non-medical professional malpractice cases.
G. Privity and Third-Party Claims
Legal Malpractice: Generally requires an attorney-client relationship. Kurtz v. Heimark, 919 S.W.2d 293 (Mo. Ct. App. 1996). Missouri recognizes limited exceptions for intended third-party beneficiaries.
Accountant Malpractice: Third parties may recover under the Restatement approach where the accountant knew the work would be relied upon. Aluma Kraft Mfg. Co. v. Elmer Fox & Co., 493 S.W.2d 378 (Mo. Ct. App. 1973).
H. Breach of Fiduciary Duty
If asserting a fiduciary-duty theory, identify the relationship, the specific duty, the conduct said to breach it, and the resulting harm. Analyze that theory separately from professional negligence.
II. PRESERVATION OF EVIDENCE - LITIGATION HOLD
YOU ARE HEREBY DIRECTED TO PRESERVE ALL EVIDENCE relating to services provided to [Client Name], including but not limited to:
- Complete client file (paper and electronic)
- All correspondence and communications
- Work product, drafts, and notes

- Emails and electronic communications
- Calendar entries and scheduling records
- Internal memoranda and analysis
- Research materials
- Any recorded statements
- Professional liability insurance policies
- Quality control and review documentation
If relevant records are altered, destroyed, or concealed, we may ask the court to consider an appropriate evidentiary remedy or sanction based on the facts. No separate spoliation claim or adverse inference is presumed. Taylor v. Caesars Entertainment Operating Co., No. 4:23CV758 (E.D. Mo. Feb. 16, 2024) (discussing Missouri appellate decisions), https://www.govinfo.gov/content/pkg/USCOURTS-moed-4_23-cv-00758/pdf/USCOURTS-moed-4_23-cv-00758-0.pdf.

MISSOURI PROFESSIONAL MALPRACTICE PRACTICE NOTES
-
Five-Year Limitations Period: One of the longer limitations periods for professional malpractice.
-
Accrual under § 516.100: Determine when resulting damage was sustained and objectively capable of ascertainment; do not use a general actual-discovery trigger.
-
Real-Property Improvement Repose: For a covered designer or builder, § 516.097 generally requires suit within ten years after completion of a defective or unsafe improvement, subject to its exceptions and occupancy-permit rule.
-
Pure Comparative Fault: Plaintiff may recover regardless of percentage of fault (damages reduced proportionally).
-
Expert Testimony Required: Expert witness is generally necessary except for obvious negligence.
-
No General Damage Caps: No statutory limits on compensatory damages in non-medical professional malpractice.
-
Punitive Damages: Under § 510.261(1), except as otherwise provided by statute, the claimant must prove by clear and convincing evidence intentional harm without just cause or deliberate and flagrant disregard for others' safety. Subsection (5) bars a punitive claim in the initial pleading and requires leave of court for a later pleading.
-
Prejudgment Interest: Section 408.040's tort-demand procedure requires certified mail, specified supporting materials, a 90-day open period, timely suit, and a judgment exceeding the demand; the applicable rate is not a flat 9%.
-
Venue: If a tort count alleges injury first sustained in Missouri, § 508.010 generally places venue in the county where the plaintiff was first injured by the alleged conduct; out-of-state first injuries use the statute's separate subsection 5 rules.
-
Damage Rule: For legal malpractice, damages may accrue when they are "ascertainable" rather than when act occurred.
-
Third-Party Beneficiaries: Limited recognition for estate planning malpractice claims.

- 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.
