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. OKLAHOMA-SPECIFIC LEGAL FRAMEWORK
A. Governing Law
Professional malpractice claims in Oklahoma are governed by common law negligence principles. Key precedents include Bays v. State Farm Mutual Automobile Insurance Co., 2006 OK 22, 137 P.3d 1233 and Cosper v. Stiller, 1988 OK 33, 755 P.2d 102.
B. Statute of Limitations
Professional Malpractice: Under 12 Okla. Stat. Section 95(A)(3), actions for professional malpractice must be commenced within two (2) years from the date the cause of action accrues.
Accrual: Accrual and any tolling issue are claim- and fact-specific. In Marshall v. Fenton, Fenton, Smith, Reneau & Moon, P.C., 1995 OK 66, ¶¶ 7–10, 899 P.2d 621, the Oklahoma Supreme Court held that a legal-negligence claim does not accrue merely upon the negligent act; the claimant must also have sustained non-speculative injury or damages so that the action could be maintained to a successful conclusion. Counsel must separately analyze discovery, concealment, continuing representation, contract theories, and any other tolling or accrual issue supported by current law and the facts.
Relevant Dates in This Matter:
- Date(s) of negligent services: [Date(s)]
- Date of discovery: [Date]
- Two-year limitations period expires: [Date]
C. Comparative Negligence
Oklahoma follows a modified comparative negligence system under 23 Okla. Stat. Section 13. Recovery is barred only if the plaintiff's negligence is of a greater degree than the negligence identified by the statute; equal fault does not bar recovery.
D. Standard of Care Under Oklahoma Law
Under Oklahoma law, a professional must exercise the knowledge, skill, and ability ordinarily possessed and exercised by members of that profession in similar circumstances. Cosper v. Stiller, 1988 OK 33, 755 P.2d 102.
Key Case Law:
- Attorneys: Must exercise ordinary care, skill, and diligence that attorneys in good standing ordinarily exercise. Stroud v. Arthur Andersen & Co., 2001 OK 76, 37 P.3d 783.
- Accountants: Must perform services in accordance with GAAP and GAAS standards and exercise reasonable professional care. Stroud v. Arthur Andersen & Co., 2001 OK 76.
- Engineers/Architects: Must exercise the skill and care customarily used by practitioners in the profession.
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.
Bays v. State Farm Mutual Automobile Insurance Co., 2006 OK 22.
Exception: Expert testimony is not required when the professional's negligence is within the common knowledge of laypersons.
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
If the claim arises from bodily injury occurring on or after September 1, 2025, 23 O.S. § 61.3 generally caps noneconomic damages at $500,000, subject to statutory physical-injury, mental-injury, and misconduct exceptions. Economic damages remain uncapped. Confirm whether the pleaded professional-malpractice loss is a bodily-injury claim within the statute.
G. Privity and Third-Party Claims
Legal Malpractice: Generally requires an attorney-client relationship. Oklahoma may recognize claims by intended third-party beneficiaries in limited circumstances.
Accountant Malpractice: Third parties may recover under certain circumstances. Stroud v. Arthur Andersen & Co., 2001 OK 76.
H. Breach of Fiduciary Duty
Oklahoma recognizes breach of fiduciary duty as a separate cause of action. Professionals who occupy positions of trust owe fiduciary duties to their clients.

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.
