Comparative Review of Legal and Ethical Issues in AI-based Legal Services

This paper explores the rapid development of AI-based legal services and the resulting legal and ethical issues. As AI technology is introduced into legal advisory and related services, significant changes are occurring in the way legal work is performed and service delivery models are structured. While these changes offer benefits such as cost reduction, increased efficiency, and improved accessibility to legal services, they also raise concerns about unauthorized practice of law, personal information protection, transparency and fairness of algorithms, and changes in lawyer-client relationships. Through literature review and case analysis, this research comparatively analyzes the current status of AI legal services and regulatory approaches in the United States and Korea. Major legal issues include the legal status of legal advice provided by AI systems and the responsibility for AI-generated legal documents, while ethical issues encompass AI algorithmic bias, explainability, and personal information protection. This study comprehensively analyzes these issues and forecasts the future of AI legal services. Furthermore, it presents implications and policy suggestions for finding a balance between AI technology development and existing legal systems, and for establishing appropriate regulations and ethical standards. Through this, it seeks ways to maximize the benefits of AI technology while maintaining the intrinsic value of legal services and social trust.
