Professional Liability

For decades, Steptoe has represented major law firms and accounting firms on challenging and sensitive issues of professional liability. The firm is regularly selected to defend law firms and accounting firms facing claims alleging that they violated professional or ethical standards or engaged in criminal conduct. We have also represented other major US firms in connection with internal investigations and collateral ethical and client-related obligations, including those arising from alleged billing improprieties. A significant number of AmLaw 100 firms have turned to Steptoe to handle these important matters.

Legal Malpractice

Legal malpractice claims typically present unique and complex legal, ethical, and reputational issues. Understanding the intersection between ethical standards, conflict of interest and disciplinary rules, and professional negligence is essential. Though mastery of the law of legal malpractice is a prerequisite to practice in this area, malpractice attorneys must also understand the substantive law of the practice area at issue in the particular claim. Thus, Steptoe attorneys regularly draw on the experience and judgment of colleagues in intellectual property, class actions, products liability, corporate, international law, tax, ERISA, and other subject matter areas.

This work often extends beyond civil litigation to congressional, administrative, and grand jury investigations. Our cases have included claims arising from a wide array of fields, including patent prosecution and litigation, tax shelter opinions and litigation, political corruption, corporate advice and deal structuring, financial fraud, and regulatory advice and compliance. Steptoe also represents law firms in disputes with departed partners, frequently resolved in binding arbitration.

Accounting Malpractice

Steptoe has handled individual, multiparty, and class action cases and license proceedings alleging accounting malpractice arising from auditing work, tax advice, and IT consulting. These cases are often shareholder class actions alleging securities fraud as well as common law fraud, negligent misrepresentation, and breach of fiduciary duty claims. The firm has represented accounting firms and their partners and employees in litigation brought by corporations or bankruptcy trustees involving securities or common law claims, as well as in Section 2(e) proceedings at the US Securities and Exchange Commission (involving their continued right to practice at the SEC) and in license suspension and revocation proceedings at State Boards of Accountancy.
