A law firm is a business made up of lawyers who provide legal services to clients. These firms can range in size from a single attorney to large organizations with hundreds of lawyers. They help individuals, businesses, and government entities with various legal matters, including contracts, litigation, and criminal defense. Law firms typically specialize in specific areas of law, such as family law, corporate law, or intellectual property. They may charge clients by the hour, through flat fees, or on a contingency basis, depending on the services provided. The goal of a law firm is to represent and advise clients effectively within the legal system.
