How to Disclose AI Use to Clients Under NJ Ethics Rules

The question comes up frequently in conversations with solo attorneys: "Do I have to tell my client I used AI?"

The answer is: sometimes, yes. And figuring out when is trickier than it seems.

New Jersey's ethics framework is evolving, but the principle is clear: you disclose AI use when it affects the service the client is paying for or the client's ability to make informed decisions. The challenge is recognizing when that threshold is crossed.

The Ethical Framework

Start with the New Jersey Rules of Professional Conduct. Rule 1.4 requires you to keep clients reasonably informed about matters affecting their representation. Rule 1.6 requires you to maintain client confidentiality and treat client information carefully.

These rules don't explicitly say "disclose AI use." But they establish principles that apply: transparency, informed consent, and competent handling of client information.

New Jersey's developing guidance on AI pushes in one direction: if AI use is substantial or affects the client's interests materially, disclose it.

When Disclosure Is Required

Let's be concrete. Disclosure is required when:

AI substantially affects the advice you're giving: You used AI to research a client's legal issue, and the research shaped your strategy. The client should know the research was AI-assisted. Not because it's worse than human research (it isn't, if verified properly), but because it's different in a specific way—it was machine-generated.

AI affects the service delivery timeline or methodology: You used AI-powered contract review instead of manual review. The client is paying for legal review. If the methodology is substantially different from what the client expects, disclosure is appropriate.

AI use creates a potential conflict or limitation: You're using an AI tool that has access to certain data or that involves third-party processing of client information. The client needs to know that.

The client has specific concerns about AI: Some clients don't want AI involved in their matters. If you know that, you disclose upfront.

Disclosure is not required for:

Routine efficiency uses: You used AI to organize a client's documents for your own efficiency. You're not disclosing that because it doesn't affect the client's experience or the service they receive.

Internal process improvements: You use an AI-powered calendar tool. You use AI-assisted grammar checking for your written work. These are behind-the-scenes efficiency tools that don't materially affect the client.

Trivial or supporting uses: You used ChatGPT to brainstorm email subject lines. You used an AI tool to format a document. These don't rise to the level of disclosure.

The principle: if the client would want to know, disclose. If it's purely internal efficiency that doesn't affect the client experience, it's probably not necessary.

How to Have the Conversation

This is the part that intimidates solo attorneys. The good news: clients are generally fine with AI use when you're transparent about it.

The bad reaction comes from finding out after the fact, or discovering that you were sloppy about it. Disclosure prevents both.

Here's how to frame it, depending on the context:

In initial consultation or engagement letter: "For legal research, I use a combination of traditional database research and AI-assisted research tools. These tools help me identify relevant cases more efficiently. I verify all cases and citations I rely on before providing advice."

That's it. One sentence. It's transparent without being alarming. It indicates you have a process.

When starting a specific AI-assisted task: "Your contract is going to be reviewed using an AI-assisted contract review tool that flags variations from standard terms. I'll personally review all flagged issues and provide my analysis. This speeds up the review while maintaining the quality of my work."

Again, straightforward. It explains what's happening and why.

For AI-assisted writing or drafting: "I'll draft sections of this brief using AI-assisted writing tools, then substantially revise and verify all citations. My final work product is my work product—verified and personally reviewed."

This is actually a moment where disclosure builds confidence. It shows you have a process. It shows you're not just blindly using AI.

For client intake processing: "Your intake information will be processed through an AI system to organize it and flag key issues. I review all of this personally before our meeting."

Clients understand that organizing information is mechanical work. They're fine with AI doing the organizing.

The Conversation You Avoid

There's one conversation you want to prevent: the client finding out you used AI from someone other than you.

This happens when:

• An opposing counsel spots AI characteristics in your work and questions it
• The client asks directly and you haven't mentioned it
• Something goes wrong and the client discovers AI was involved

In these scenarios, disclosure comes too late. It looks like you were hiding it. Trust erodes.

The solution: disclose proactively on anything that matters. It's a 30-second conversation that prevents a much harder one later.

NJ-Specific Considerations

New Jersey's guidance is still evolving, but the state has signaled certain expectations:

Competency demonstrations: If you disclose AI use, be ready to explain that you understand the tool and have a verification process. This is implicit in good disclosure.

Confidentiality care: If you're using cloud-based AI tools, New Jersey expects you to understand the data handling involved. This is especially important for IOLTA matters.

Documentation: Have records showing you disclosed AI use appropriately. This is your protection if an ethics question comes up.

The NJSBA task force has been thoughtful about AI guidance. The expectation isn't perfection. It's reasonableness. A solo attorney with documented policies and transparent disclosure is in a strong position.

Practical Implementation

Build disclosure into your systems:

Update your engagement letter: Add a paragraph about AI use in your legal work. Make it standard, not special. This normalizes it.

Create a disclosure script: For routine AI uses, have standard language ready. You don't need a long explanation. You need clear, brief language.

Document disclosures: When you disclose AI use to a client, note it in the file. Not for paranoia—for your own protection and record-keeping.

Ask about client preferences: Some clients have preferences about AI. Ask in your engagement letter: "Do you have any preferences or concerns about the use of technology in your matter?" If they do, honor that.

Handle sensitive matters carefully: For criminal matters, IOLTA cases, or cases involving vulnerable clients, be more conservative. Disclose more readily. The principle is: if there's any doubt, disclose.

The Bigger Principle

Disclosure isn't just an ethics requirement. It's actually a business advantage.

Clients trust attorneys who are transparent about how they work. They understand that AI, when used properly, doesn't lower the quality of their work—it improves efficiency.

The attorneys who position themselves as "I use AI thoughtfully and I'll tell you exactly how" are the ones building stronger client relationships.

The ones who hide AI use are the ones who end up in ethics complaints.

Pick the first approach. It's better practice and better business.
