Definition of Law firm

A law firm is a business entity formed by one or more lawyers to engage in the practice of law. The primary service provided by a law firm is to advise clients (individuals or corporations) about their legal rights and responsibilities, and to represent their clients in civil or criminal cases, business transactions and other matters in which legal assistance is sought. Smaller firms tend to focus on particular specialties of the law (e.g. patent law, labor law, tax law, criminal defense, personal injury); larger firms may be composed of several specialized practice groups, allowing the firm to diversify their client base and market, and to offer a variety of services to their clients.
