AI receptionist for law firms: intake, confidentiality and the ethics rules to check
What calls a firm gets, how much an AI should take down at intake, where legal advice starts and what ABA Model Rules 5.3, 1.6 and 1.18 mean for a phone assistant.

What should an AI receptionist for a law firm do?
An AI receptionist for a law firm answers calls the firm would otherwise miss, takes the minimum facts needed for a conflict check, books consultations and routes urgent matters to a lawyer. It must never give legal advice or promise representation, and the firm stays responsible for supervising it and for protecting what callers tell it.

A firm’s phone mixes potential clients, existing clients, other lawyers and the occasional crisis. An AI receptionist can sort and schedule most of them, but its real value is not losing the potential client who calls once, gets voicemail and calls the next firm on the list.
| Call type | What the AI should do | When to hand to a person |
|---|---|---|
| Potential new client | Ask your intake questions, collect party names for the conflict check, book a consultation | Caller is facing an imminent deadline or hearing |
| Existing client asking about their matter | Take a message for the responsible lawyer or paralegal | Always for case details: the AI should not discuss the matter |
| Opposing counsel, court or another firm | Take the name, matter and callback number | Mark urgent if a court or deadline is mentioned |
| Someone just arrested, served or in danger | Follow the firm’s urgent script and transfer | Always, immediately; if someone is in danger, the script should direct them to 911 |
| “Do I have a case?” or “What should I do?” | Explain it cannot give legal advice and offer a consultation | If the caller insists, take a message for a lawyer |
| Fee questions | Give only the fee information the firm has approved, such as whether consultations are free | Any quote for a specific matter |
| Vendors and sales calls | Take a message or decline politely | Rarely |
How much should an AI receptionist take down from a potential client?
Less than you might think. ABA Model Rule 1.18 says a person who consults a lawyer about possibly forming a client-lawyer relationship is a prospective client, and that information learned from them generally cannot be used or revealed even if the firm never takes the matter. If the information could be significantly harmful to the caller, the firm can be barred from representing someone with materially adverse interests in the same or a substantially related matter. One way the rule lets a firm limit that risk is by taking reasonable measures to avoid exposure to more disqualifying information than is reasonably necessary to decide whether to represent the person (ABA Model Rule 1.18).
For an AI receptionist, that suggests a deliberate order:
- Caller’s name and contact details.
- Names of the other parties, for the conflict check.
- The type of matter in a sentence, such as a car accident or a lease dispute.
- Urgency: any court date, deadline or hearing.
- Book a consultation; the detailed story waits until the conflict check clears.
Your intake questions will differ by practice area, but the principle holds: collect what the check needs first.
How does an AI receptionist avoid giving legal advice?
By having nothing to say on the merits. Callers will ask whether they have a case, what a deadline is or whether they should sign something. The script should answer each the same way: the assistant is not a lawyer, cannot advise, and can book time with one. It should also avoid any wording that sounds like the firm has agreed to represent the caller.
Test this before buying. Call as a frustrated potential client and push for an answer to a legal question three times. A system that eventually improvises one is not fit for a law firm.
What do ABA Model Rules 5.3 and 1.6 mean for an AI receptionist?
Model Rule 5.3 covers nonlawyers employed or retained by a lawyer. Partners and lawyers with managerial authority must make reasonable efforts to ensure the firm has measures giving reasonable assurance that such a person’s conduct is compatible with the lawyer’s professional obligations, and supervising lawyers carry the same duty. A phone-answering vendor is retained by the firm, so the prudent course is to supervise it like any outside assistant: approve its scripts, review its calls and correct it when it gets something wrong.
Model Rule 1.6(c) requires a lawyer to make reasonable efforts to prevent the inadvertent or unauthorized disclosure of, or unauthorized access to, information relating to the representation of a client. In Formal Opinion 512 (July 29, 2024), the ABA’s ethics committee said lawyers using generative AI must keep that duty in mind, that other rules extend similar protection to former and prospective clients, and that state and local bar ethics committees are likely to keep issuing guidance on specific tools. The Model Rules are a template; your state’s adopted rules and bar opinions are what bind you.
| What to check before you buy | Why it matters |
|---|---|
| Who at the vendor can access recordings and transcripts? | Rule 1.6(c) reasonable efforts against unauthorized access |
| Is caller data used to train models shared with other customers? | Information could leave the firm’s control |
| Can you set retention and delete calls? | Prospective-client information you should not keep |
| Can you approve every script and intake question? | Rule 5.3 supervision of nonlawyer assistance |
| Does the greeting say it is an AI and not a lawyer? | Reduces risk of callers relying on it as advice |
| How are urgent matters escalated, and to whom? | Missed deadlines and emergencies |
| What does your state bar say about AI tools? | State rules and opinions can differ from the Model Rules |
Perimattic AI Receptionist’s terms on data access, retention and model training will be published before launch. It makes no claim to meet any bar’s rules; that assessment belongs to the firm.
AI receptionist, legal answering service or in-house receptionist?
The Bureau of Labor Statistics puts the median wage for receptionists in professional, scientific and technical services, which includes law firms, at $18.56 an hour in May 2025 (BLS Occupational Outlook Handbook). Cost aside, the options differ most in after-hours coverage and judgment:
| Factor | AI receptionist | Answering service | In-house receptionist |
|---|---|---|---|
| Evening and weekend potential clients | Answered and booked | Answered; often message only | Voicemail unless staffed |
| Intake questions | Your script, every time | Your script, varies by agent | Your script plus experience |
| Conflict-check data | Collected in a set order | Collected if scripted | Collected and often run |
| Spotting an unusual or sensitive caller | Limited; relies on escalation rules | Varies | Strongest |
| Supervision burden on the firm | Review scripts and transcripts | Review scripts and messages | Ordinary staff supervision |
Potential clients who call after hours are the ones most likely to be lost. Estimate what that costs with the missed-call revenue calculator, and compare pricing models in the AI receptionist cost guide.

AI receptionists for law firms, answered
Is it ethical for a law firm to use an AI receptionist?
The ABA Model Rules do not ban it, but they put the responsibility on the firm. Rule 5.3 asks lawyers to make reasonable efforts to ensure nonlawyer assistance is compatible with their professional obligations, Rule 1.6(c) asks for reasonable efforts to protect client information, and ABA Formal Opinion 512 applies these duties to generative AI. Check your own state’s rules and bar guidance too.
Can an AI receptionist run a conflict check?
It can collect what your conflict check needs, usually the caller’s name and the names of the other parties, and pass it to whoever runs the check. The check itself, and the decision to take the matter, should stay with the firm. Collecting party names before the story also helps limit exposure to information from a prospective client the firm may not be able to represent.
Should callers be told they are speaking to an AI?
It is good practice to say so in the greeting, along with the fact that the assistant is not a lawyer and cannot give legal advice. That reduces the chance a caller treats anything said as advice or believes the firm has agreed to represent them. Some state bars may set their own expectations, so check yours.
