Professional Liability


Baker Botts regularly defends professional service firms – including Am Law 150 law firms, large accounting firms, and consulting firms – against professional liability claims nationwide. In addition to traditional malpractice, professional negligence, and breach of duty suits filed by their clients, these firms are regularly targeted by non-clients who assert fraud, securities, and other claims. Our professional liability lawyers are adept at defending professional service providers in individual and class action lawsuits in federal and state courts, as well as navigating through substantive and procedural issues in a variety of arbitration forums, administrative proceedings, and regulatory settings.

Law Firms

We regularly represent other lawyers and law firms in the defense of malpractice, fraud, and other claims arising from a myriad of engagements – brought by firms’ clients, parties claiming to be clients, or third parties. Our professional liability lawyers are proud to earn the trust of other lawyers in cases challenging their legal services.

With our full-service offering, our professional liability lawyers regularly work with our colleagues across other departments, including intellectual property, corporate, tax, and real estate lawyers, to ensure a breadth and depth of experience in defending the underlying work-at-issue in legal malpractice cases. Law firms also turn to us when they need outside counsel for other types of disputes, including defending clients against disqualification attempts, employment matters, and internal disputes.

Accounting Firms

We pride ourselves in understanding the complex nature of the accounting profession and the unique regulatory and litigation challenges accounting firms face. We are a leading national firm in the defense of accountants’ liability claims. Our professional liability lawyers regularly represent the largest accounting firms and their professionals in disputes related to audit services, tax compliance, and consulting work.

Our lawyers also advise accountants and accounting firms in administrative proceedings and investigations initiated by state and federal regulators. We have routinely represented accounting professionals and firms in connection with inquiries and enforcement matters conducted by the Public Company Accounting Oversight Board and the Securities and Exchange Commission, and state accountancy boards.

Consulting and Other Professional Firms

We also defend large business consulting firms and other professional firms against malpractice and other professional liability cases. These claims often stem from work performed by these firms for their clients, but they can also be brought by non-clients, including beneficiaries of trusts.
