Your engagement letter needs AI clauses — and most firms haven't added them.

Your engagement letter needs AI clauses — and most firms haven't added them. Clients are asking whether you use AI. Courts are requiring disclosure. Ethics opinions are recommending transparency. But the average law firm engagement letter still reads like it was written in 2019, with zero mention of the AI tools that now touch every matter.

Adding AI clauses to your engagement letter isn't just best practice — it's risk management. Clear disclosure protects you from ethics complaints, manages client expectations, and preempts the increasingly common question: "Are you using AI on my case?" Here are the specific clauses you need.

Clause 1: General AI Use Disclosure

Every engagement letter should include a baseline AI use disclosure. This clause informs clients that your firm uses AI tools as part of its practice and establishes the framework for how AI is deployed.

Sample language:

*"Our firm utilizes artificial intelligence tools as part of our legal practice, including AI-powered research platforms, document analysis tools, and drafting assistance technology. These tools are used to enhance the efficiency and thoroughness of our legal services. All AI-generated work product is reviewed, verified, and approved by licensed attorneys before being relied upon or delivered to clients. Our use of AI tools does not change our professional obligations to you, including our duties of competence, confidentiality, and diligence."*

Why this works: It's transparent without being alarming. It establishes that AI is a tool used by attorneys, not a replacement for attorney judgment. It explicitly connects AI use to your professional obligations, reassuring clients that the ethical framework remains intact.

Clause 2: Confidentiality and Data Protection

Clients' number one concern about AI is confidentiality. This clause addresses data protection directly and specifically.

Sample language:

*"When using AI tools in connection with your matter, we take the following data protection measures: (a) We use only enterprise-grade AI platforms that contractually prohibit the use of client data for model training or improvement; (b) We do not input privileged communications, trade secrets, or highly sensitive information into AI tools without your prior written consent; (c) All AI tools used by our firm comply with industry-standard security protocols, including data encryption and access controls; (d) Our AI use practices comply with our obligations under [applicable state] Rules of Professional Conduct regarding client confidentiality."*

Key considerations: This clause makes specific commitments you must actually follow. Don't include language about enterprise-grade tools if your associates are using free ChatGPT. The clause should reflect your actual practices, not aspirational ones.

Clause 3: Scope of AI Use and Client Opt-Out

Some clients — particularly those in litigation with trade secrets, pending M&A transactions, or government investigations — may want to restrict or prohibit AI use on their matters. This clause gives them that option.

Sample language:

*"If you prefer that we limit or refrain from using AI tools in connection with your matter, please notify us in writing. We will accommodate your preferences regarding AI use, though this may affect the timeline and cost of our services. Absent written instruction to the contrary, we will use AI tools at our professional discretion in accordance with our firm's AI Use Policy, a copy of which is available upon request."*

The practical reality: Very few clients opt out. But offering the option demonstrates respect for client autonomy and protects you from claims that you used AI without consent. The clause also manages expectations about cost — clients who restrict AI use should understand that matters may take longer and cost more.

Clause 4: AI-Specific Billing Practices

The thorniest AI engagement letter issue is billing. If AI cuts a 6-hour research task to 90 minutes, do you bill for 6 hours (the value delivered) or 90 minutes (the time spent)? This clause addresses billing transparency.

Sample language:

*"Our use of AI tools may reduce the time required to complete certain tasks, and our billing reflects actual time spent by our attorneys and staff. We do not bill for AI tool processing time. The cost of AI tools and technology is included in our firm's overhead and is not charged separately to clients. If AI-assisted work allows us to complete tasks more efficiently, those efficiencies are reflected in reduced billing for those tasks."*

Alternative for value-based billing firms:

*"Our fees reflect the value of legal services delivered, not solely the time expended. Our use of AI tools enables us to deliver higher-quality work product more efficiently. Our fee arrangements account for the investment we make in AI technology and the enhanced capabilities it provides."*

Choose the version that matches your billing model. Hourly firms should commit to billing actual time. Value-based firms have more flexibility but should still be transparent about how AI affects pricing.

Clause 5: Court Disclosure and Compliance

With 300+ federal judges requiring AI disclosure, your engagement letter should address court compliance obligations.

Sample language:

*"Many federal and state courts now require attorneys to disclose the use of AI tools in court filings. Where such disclosure is required, we will comply with all applicable court rules, standing orders, and local requirements regarding AI disclosure. We will include appropriate AI use certifications in our court filings as required. Our compliance with court AI disclosure requirements does not constitute an admission that AI-generated work product is less reliable than traditionally produced work product — rather, it reflects our commitment to transparency and compliance with evolving court procedures."*

Why this matters: Clients seeing AI disclosure language in court filings for the first time may be alarmed if they weren't warned. This clause prepares them for the disclosure and frames it positively — as compliance and transparency, not as a warning about AI reliability.

The Bottom Line: Five clauses, five minutes to add to your engagement letter template. General AI disclosure, confidentiality protections, client opt-out rights, billing transparency, and court compliance. These clauses protect you from ethics complaints, manage client expectations, and position your firm as transparent and professionally responsible about AI adoption. Update your template today — every new engagement without these clauses is an unnecessary risk.
