Legal service typically refers to professional advice or representation offered by lawyers or law firms to individuals, businesses, or organizations. It encompasses a broad spectrum of activities including legal consultation, document drafting, litigation, and regulatory compliance. A "law firm" refers to a business entity formed by one or more lawyers to engage in the practice of law. These firms vary widely in size, scope of practice, and specialization, catering to diverse client needs from personal injury cases to corporate mergers. Both legal services and law firms play crucial roles in upholding justice and providing legal solutions in society.
