Telling Clients You Used AI: What a Client Communication Policy for NJ Law Firms Actually Needs to Say

Most conversations about AI and professional responsibility in New Jersey have centered on competence, candor, and supervision. Those are real concerns. But there's a quieter obligation sitting underneath all of them that small-firm attorneys tend to treat as an afterthought: the duty to communicate.

RPC 1.4 requires that attorneys keep clients reasonably informed about the status of their matters and promptly respond to reasonable requests for information. What does that have to do with AI? More than most NJ practitioners realize.

If an AI tool is generating the first draft of a client's contract, summarizing deposition transcripts, or flagging issues in a lease review, that's a material fact about how the work is being done. Whether the client has a right to know, and in what form, isn't a hypothetical ethics question anymore. It's a practice management decision that every NJ solo and small firm should be making deliberately, not on the fly.

What RPC 1.4 Actually Covers Here

The rule has two operative pieces that matter for this discussion. First, an attorney must "keep the client reasonably informed about the status of the matter." Second, an attorney must "explain a matter to the extent reasonably necessary to permit the client to make informed decisions regarding the representation."

That second clause is the one that creates real exposure in an AI context. If a client is paying for legal analysis and a significant portion of the analytical scaffolding was generated by an AI tool the client doesn't know about, there's a reasonable argument that the client lacks information needed to evaluate the representation. Not every client will care. Some will prefer efficiency. But the choice to tell them, or not, shouldn't be made by default.

The NJ Supreme Court hasn't issued a formal opinion specifically on AI disclosure obligations yet, but the broader framework is already there. The question isn't whether RPC 1.4 applies. It's how to satisfy it practically.

What a Client Communication Policy on AI Use Should Actually Cover

A one-sentence disclaimer buried in your engagement letter isn't a policy. Here's what a functioning policy actually needs to address:

Which tasks trigger disclosure. Not every AI touchpoint requires a conversation. Using AI to draft a time entry or proofread a cover letter is different from using it to analyze a client's damages exposure or draft a legal memorandum the client will rely on. Your policy should draw a clear internal line between administrative AI use and substantive AI use, and require disclosure only when the AI is contributing to client-facing legal work product.

How and when you disclose. The engagement letter is the right place to set baseline expectations. Something plain and honest works well: a short paragraph explaining that the firm may use AI-assisted tools to improve efficiency, that all AI-generated work is reviewed and verified by the supervising attorney, and that the client can ask questions about this at any time. That's not boilerplate, it's a genuine representation you need to be able to back up.

Client opt-out rights. Some clients, particularly those with heightened data sensitivity (think healthcare providers, executives in M&A transactions, or anyone with trade secret exposure), may not want their information processed through AI tools at all. Your policy should identify whether you'll honor opt-out requests and what happens to the engagement if a client exercises that right.

How you document AI use internally. This one's mostly for your own protection. If a dispute arises about the quality of your work, you want a record of which tasks involved AI assistance and what review steps you took. A simple notation in your matter management system works fine. You don't need elaborate logging software.

A Practical Drafting Note

When you update your engagement letter to add an AI disclosure, avoid vague language like "cutting-edge tools" or "advanced technology." Write it the way you'd explain it to a client sitting across from you. Something like: "We sometimes use AI-assisted software to help draft documents or analyze materials more efficiently. An attorney always reviews and takes responsibility for the final work product."

Clients read plain language. They also notice when it sounds evasive.

One Thing Firms Tend to Skip

The engagement letter gets the attention, but the harder scenario is a mid-matter conversation, a client who asks directly, "Did you use AI on this?" Your staff needs a consistent, honest answer ready. That means whoever interacts with clients (including paralegals and legal assistants) should know your firm's policy, understand which tools you use, and not be caught off guard by the question.

Train your team on this before the question comes up in a deposition or a bar complaint. The NJ Rules of Professional Conduct don't just bind the supervising attorney, they shape what that attorney is responsible for when a non-lawyer says something inaccurate to a client about how the work was done.

Start with your engagement letter template this week. Add two or three plain sentences about AI use. Then decide, in writing, where your firm draws the line between administrative and substantive AI tasks. That decision, documented, is the core of a defensible client communication policy.
