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. CALIFORNIA-SPECIFIC LEGAL FRAMEWORK

A. Governing Law

This claim is governed by California common law principles of professional negligence and the California Code of Civil Procedure.

B. Statute of Limitations

Legal Malpractice: For a covered claim other than actual fraud, CCP Section 340.6(a) generally sets the earlier of:

• One (1) year after the plaintiff discovers, or through reasonable diligence should have discovered, the facts constituting the wrongful act; but
• Four (4) years after the wrongful act or omission, subject to the statute's tolling and exceptions.

Tolling Events for Legal Malpractice: Under CCP Section 340.6(a), the applicable period is tolled while:

1. The plaintiff has not sustained actual injury.
2. The attorney continues to represent the plaintiff on the specific matter.
3. The attorney willfully conceals the wrongful act or omission, but this tolls only the four-year limit.
4. A legal or physical disability restricts the plaintiff's ability to commence the action.
5. A lawyer-client fee or cost dispute is pending under the State Bar fee-arbitration procedures. The statute defines that interval from the arbitration request through 30 days after notice of the award or termination.

The statute has a separate two-year period after final postconviction exoneration when factual innocence of an underlying criminal charge is an element of the claim. Calculate the deadline for the actual claim and tolling facts.

Other Professional Malpractice: Generally, two (2) years from accrual under CCP Section 339 (negligence based on oral representations) or four (4) years under CCP Section 337 (written contract basis).

Design Professionals - Statute of Repose: Under CCP Section 337.15, actions for latent defects against design professionals must be brought within 10 years of substantial completion.

Relevant Dates in This Matter:

• Date(s) of negligent services: [Date(s)]
• Date of discovery: [Date]
• Limitations period expires: [Date]

C. Comparative Fault

California follows pure comparative fault under Li v. Yellow Cab Co., 13 Cal.3d 804 (1975). A plaintiff's recovery is reduced by their percentage of fault but is not barred regardless of the percentage.

Our investigation establishes that our client bears no fault for the damages caused by the defendant's professional negligence.

D. Standard of Care Under California Law

Under California law, a professional must exercise that degree of skill, prudence, and diligence that members of the profession commonly possess and exercise.

Attorney Standard: An attorney must possess the degree of learning, skill, and ability ordinarily possessed by attorneys practicing in California. The attorney must apply that learning, skill, and ability with reasonable diligence and care. Kirsch v. Duryea, 21 Cal.3d 303 (1978).

Accountant Standard: An accountant must exercise the care and skill ordinarily used by reputable accountants. Bily v. Arthur Young & Co., 3 Cal.4th 370 (1992).

Architect/Engineer Standard: Design professionals must exercise ordinary skill and competence of members of their profession. Huber, Hunt & Nichols, Inc. v. Moore, 67 Cal.App.3d 278 (1977).

E. Certificate of Merit - Design Professionals

Under CCP Section 411.35, the plaintiff's attorney in an action for professional negligence against a licensed architect, engineer, or land surveyor generally must file and serve the required certificate on or before the date the complaint or cross-complaint is served on a defendant or cross-defendant. The certificate must state one of these bases:

• File a certificate declaring that the attorney has reviewed the facts, consulted with a design professional, and concluded there is reasonable and meritorious cause for filing; OR
• If the limitations period would impair the action before the consultation certificate can be obtained, file a certificate stating that basis and file the consultation certificate within 60 days after filing the complaint; OR
• Certify that three separate good-faith attempts to consult three separate qualifying design professionals were unsuccessful because none agreed to consult.

F. Expert Witness Requirements

Expert testimony ordinarily establishes the professional standard of care and breach. The 2026 Judicial Council civil instructions recognize an exception when the conduct required by the circumstances is within a layperson's common knowledge. Assess the exception for the profession and alleged error; Unigard Ins. Group v. O'Flaherty & Belgum, 38 Cal.App.4th 1229 (1995), does not make expert testimony essential in every claim.

Exception: Expert testimony is not required where the negligence is within the common knowledge of laypersons.

Proof status: ☐ A qualified expert has reviewed the relevant materials. ☐ Counsel has identified a claim-specific common-knowledge basis for proceeding without expert proof: [________________________________]. ☐ Expert review remains pending.

G. Damage Caps

California does not impose statutory caps on compensatory damages in professional malpractice cases (unlike medical malpractice under MICRA).

Punitive Damages: Available upon clear and convincing evidence of malice, oppression, or fraud under Civil Code Section 3294.

II. PRESERVATION OF EVIDENCE - LITIGATION HOLD

YOU ARE HEREBY DIRECTED TO PRESERVE ALL EVIDENCE relating to the professional services provided to [Client Name], including but not limited to:

• Complete client files (paper and electronic)
• All drafts and working papers
• Correspondence (including emails, texts, and messages)

• Conflict check documentation
• Professional liability insurance policies
• [For Attorneys:] Case files, pleadings, research memoranda
• [For Accountants:] Work papers, tax returns, financial statements
• [For Architects/Engineers:] Drawings, specifications, calculations, project files

If relevant evidence is willfully suppressed, the trier of fact may consider that conduct when drawing inferences under Evidence Code Section 413. Discovery sanctions may be sought for misuse of the discovery process when authorized by the applicable discovery provisions and ordered after notice and an opportunity to be heard (CCP Section 2023.030).

• Legal Malpractice Limitations: One year from discovery but no more than four years from the act (CCP Section 340.6).

• Tolling for Continued Representation: The limitations period is tolled during continued attorney representation on the specific matter.

• Certificate of Merit for Design Professionals: CCP Section 411.35 generally requires the attorney to file and serve the certificate on or before service of the complaint or cross-complaint.

• Trial Within a Trial: Legal malpractice plaintiffs must prove they would have won the underlying case.

• Transactional Malpractice: Must prove "but for" causation per Viner v. Sweet.

• Expert proof: It is generally used to establish professional care, subject to the common-knowledge exception discussed in CACI No. 518 (2026 edition). Identify the claim-specific basis before omitting an expert.

• No MICRA Caps: Professional malpractice is not subject to medical malpractice damages caps.

• Accountant Third-Party Liability Limited: Bily v. Arthur Young limits accountant liability to third parties.

• Venue: Proper where defendant resides or where the claim arose.
