How law firms can use Codex in legal work

Hello, this is Legal Agent.

This English page is prepared together with the Japanese article for readers who prefer English. LegalAgent is an AI Native Law Firm focused on corporate legal work, startup legal support, M&A support and practical legal outsourcing for modern companies.

Overview

This article explains practical ways to use Codex in legal work, including document organization, comparison, drafting support, issue extraction and knowledge reuse.

Key points

• Codex can support legal work where files, context and instructions are structured
• Useful use cases include contract comparison, issue lists, chronology building and draft preparation
• Attorney review remains necessary for legal conclusions and client-facing advice
• The workflow should define what AI may do and where human approval is required

Practical perspective

In practice, this topic should be reviewed together with the transaction structure, internal approval flow, counterparty relationship, business priority and risk tolerance. Generative AI can support initial organization, comparison and drafting, but attorneys or the legal team should remain responsible for final legal judgment.
