Law Firm Practice

For several decades, the nation’s top law firms and attorneys have turned to us for their most sensitive matters—when there is risk of reputational damage as a result of claims against the firm or the financial risks are significant. Clients rely on us to obtain favorable results and know us as the “lawyers’ lawyers.”

Clients seek our advice in legal malpractice actions, sanctions motions, investigations and related matters. We have litigated in state and federal court and have successfully handled matters at trial and appeal, including arguing numerous cases before the New York Court of Appeals and the U.S. Court of Appeals for the Second Circuit. In addition, law firms trust us to provide advice in connection with internal issues and disputes with other law firms.

Simpson Thacher has a sterling reputation across a wide spectrum of legal practice areas, including banking and credit, capital markets, securities, mergers and acquisitions, real estate, tax, intellectual property and ERISA. Lawyers and law firms facing issues in these areas know that our depth of knowledge and skills in those practice areas will be critical to resolving disputes.

“A ‘first-rate law firm,’ with ‘attorneys of the highest caliber.’”
