Ethical Considerations
Important: Every bar association is issuing guidance on AI use. General principles:
- Verify everything — AI makes confident mistakes
- Don’t upload confidential data to consumer AI tools
- Disclose AI assistance where required
- Maintain competence in reviewing AI output
- Check local rules — they’re evolving rapidly
Enterprise legal AI tools typically offer better confidentiality protections than consumer tools.
The Bottom Line
AI won’t replace lawyers, but lawyers using AI will replace lawyers who don’t.
Start with one tool that addresses your biggest bottleneck. For most:
- High document volume → Contract review AI
- Research-heavy practice → Legal research AI
- Client acquisition → Intake automation
- Administrative overload → Practice management
The ROI is measured in hours saved per case. Even modest time savings compound significantly across a practice.
