■ Background: Limitations of Library Research and the Need for Efficiency in a Solo Practice
P&M Law Office handles a wide range of cases, from general civil matters to corporate legal affairs, focusing on divorce and traffic accidents. While Representative Attorney Yuki Hayashimoto maintained a one-stop service system for all cases, research tasks had become a bottleneck.
Investigating books and precedents required trips to the Osaka Bar Association library, forcing the firm to conduct research in bulk once every few weeks. This led to delays in cases waiting for research results and concerns about missing information while manually checking documents one by one.
Although the firm tried e-book services and generative AI tools, they could not be used practically due to concerns about content comprehensiveness and information reliability, making the establishment of a trustworthy research foundation an urgent issue.
■ Main Results from the Introduction
Significant Reduction in Research Time: Including travel time to the library, research time was reduced by an estimated 90%. In the inheritance case that triggered the introduction, research that previously took 3 hours was completed in just 30 minutes. The ability to instantly look up questions as they arise has made managing multiple cases simultaneously much smoother.
Improved Output Quality: The ability to conduct comprehensive research has improved the accuracy of literature cited in documents. In a case involving power harassment, the firm pinpointed a court ruling that recognized compensation far exceeding the usual standard and used it in document preparation.
Realization of Strategic Litigation and Negotiation: By utilizing the AI research function 'Watson & Holmes,' the firm can now identify not only precedents supporting their own arguments but also precedents that could support the opposing party's counterarguments. Being able to assess the 'strength of an argument' in advance aids in strategic planning to maximize client interests.
Peace of Mind through Verification: The ability to immediately access the original sources underlying AI-generated summaries allows the firm to verify the accuracy of the summaries firsthand before using them in practice, providing peace of mind.
■ Comment
Yuki Hayashimoto, Representative Attorney, P&M Law Office
'I think many lawyers feel anxious about whether they have truly exhausted their research, especially in a solo practice like ours. Legalscape completely alleviates that anxiety. It allows immediate access to reliable books and precedents, and you can verify the sources with your own eyes. I am also very satisfied with the breadth of the content covered; I was surprised that even detailed administrative notices are included. It has become an indispensable tool not just for research but for strategic planning to maximize client interests.'
