Law firms across the United States provide the predominant method by which lawyers organize themselves professionally. A law firm provides each individual lawyer with greater resources than any individual lawyer would be able to attain if acting independently of the law firm. Law firms provide their constituent lawyers with service including professional office space, professional support staff, and legal research teams. Law firms allow each lawyer to worry less about the infrastructure needed to successfully practice law, and lets the lawyer instead worry about the actual practice of law, whether the arguments in the courtroom itself, filing legal briefs and memorandums, or research into the case law, depending on the individual preference of the particular lawyer.
