⚠️ Challenges and Limitations of Using AI in Law
AI tools are powerful.
But they’re not perfect.
Before you rely fully on AI in your legal work, you should know the risks.
1. Data Privacy & Confidentiality
Lawyers handle sensitive data.
Uploading legal documents to cloud-based AI tools can be risky if not encrypted.
Always check where your data is stored and how it’s protected.

AI can sometimes give wrong or outdated legal answers.
It’s especially true with generative models like ChatGPT or Harvey.
Always review AI-generated outputs carefully.
3. Ethical Concerns
Some jurisdictions may restrict how AI is used in legal work.
You must follow your local rules of professional conduct.
For example, don’t rely on AI to replace legal advice without review.
4. Tool Dependency
Overuse of AI might reduce critical thinking.
Lawyers still need to analyze cases, think strategically, and argue in court.
5. Cost Barriers
Many AI tools charge subscription fees.
For small firms, the price may be too high without a clear ROI.
