Frequently Asked Questions

Is it ethical to use AI in legal practice?

Yes, when used properly. The ABA and state bars recognize AI as a tool that can enhance legal services. The key is maintaining competence, confidentiality, supervision, and candor. Use enterprise AI tools with proper security, always verify AI outputs, and disclose AI use appropriately.

What about AI citing fake cases?

This is a real risk with general AI tools. Always verify that cases exist, check citations, and confirm holdings. Use legal-specific AI platforms that cite to verified databases when possible. Never submit AI-generated work product without thorough verification.

How do I protect client confidentiality with AI?

Use only enterprise AI platforms with proper confidentiality agreements. Ensure the vendor doesn't train on your data. Get client consent for AI use when appropriate. Never input client data into free or consumer AI tools.

Will AI replace lawyers?

AI will not replace lawyers, but lawyers using AI will outcompete those who don't. AI excels at document review, research assistance, and drafting—tasks that consume time but don't require human judgment. Lawyers remain essential for strategy, advocacy, judgment, and client relationships.

Where should a law firm start with AI?

Start with client intake and document drafting—high impact, lower risk applications. Once comfortable, expand to contract review and research assistance. Build policies and training before enterprise-wide deployment.

Conclusion

AI automation is transforming legal practice, enabling lawyers to deliver better service more efficiently while focusing on the high-value work that truly requires legal judgment. The firms implementing AI thoughtfully today are building sustainable competitive advantages.
