Professional liability claims arise when clients or third parties allege that a professional service provider — an accounting firm, law firm, financial advisor, broker-dealer, or consulting organization — failed to meet the applicable standard of care in the course of a professional engagement. These claims may sound in negligence, breach of fiduciary duty, breach of contract, or statutory violations, and frequently seek substantial damages tied to financial losses attributed to the alleged professional failure. In the accounting context, claims often center on audit failures, tax advisory errors, or financial reporting deficiencies; in the legal context, on missed deadlines, conflicts of interest, or flawed transactional advice.

A distinguishing feature of professional liability defense is the role of insurance coverage. Professional service firms typically maintain errors and omissions policies that govern the terms of the defense, the selection or approval of defense counsel, and the conditions under which indemnification is available. Coverage disputes — including reservation-of-rights letters, policy exclusions, and disputes over the allocation of defense costs — frequently arise alongside the underlying malpractice litigation and must be managed concurrently. The interplay between the insurer’s interests, the insured’s defense strategy, and potential excess exposure creates a layer of complexity not present in ordinary commercial litigation.
