Legal Answering Service: Costs, Models and What to Ask

A legal answering service is worth buying when the calls it catches turn into signed cases for less than the cases are worth, and the same month of calls can cost very different amounts depending on whether the service bills by the minute, the call or the appointment. Work out your own cost per signed case under each bill before you compare vendors.

Quick answer

Pick the job first: take a message, screen and book, or answer with software. Then ask each vendor how it bills (per minute, per call, per booked appointment or a flat plan with an allowance) and which charges it adds on top. Before you sign, confirm that every call comes back with the number dialed and an outcome (booked, not a case, wrong area, existing client, spam), or the call log cannot show which ad paid for a signed case.

What does each option do when a caller wants to hire a lawyer?

A message-taking service answers in your firm's name, collects a name and number, and emails you. Nothing is screened, so you decide on the morning call-back which messages are worth the time.

A legal intake service follows a script you approve. It can ask the questions that tell a case from a non-case, record the other party's name for a conflict check you run (a conflict check compares the names in a new matter with your past and current clients), and put a consultation on your calendar.

An AI receptionist is software that talks to the caller. It can greet and route quickly. A caller who is hurt, upset or unclear tests it hardest, so run your three worst real calls through it before you trust it with a live line.

The fourth option is a person you hire. You control the script fully, but you pay even when the phones are quiet. The right pick depends on how many calls your staff cannot take, so count last month's calls that rang out, went to voicemail or waited long. How intake steps and wait times connect to signed cases lists the numbers worth pulling from those records.

How do vendors bill, and where does the bill grow?

Every billing shape has its own weak spot, and the table shows where.

Smith.ai's human receptionist plans are Starter at $300 a month for 30 calls ($11.50 for each call over 30), Basic at $810 for 90 calls ($10.50 over) and Pro at $2,100 for 300 calls ($8.50 over), with Enterprise priced on request. Per-call add-ons include $0.50 for conflict checks, $1.00 for a dedicated Spanish line and $0.25 for recording and transcription; inbound call tracking numbers cost $5 a month each, and spam is not charged (Smith.ai, checked 2026-10-12).

Smith.ai prices its AI receptionist on a separate page: Free covers 25 calls a month ($3.00 a call after that), and Pro starts at $150 a month for 75 calls ($2.50 for each extra call) (Smith.ai, checked 2026-10-12).

Ruby bills by receptionist minutes, not calls: $250 a month for 50 minutes, $395 for 100, $720 for 200 and $1,725 for 500, and it says there are no additional or hidden fees for activation, onboarding, setup or customization (Ruby, checked 2026-10-12). The page shows no overage rate, so get that figure in writing. Answering Legal shows no prices until you fill in a form (name, company, email, cell phone and whether you are an attorney) or call, and the page says there are no long-term contracts and no setup fees (Answering Legal, checked 2026-10-12). I am not ranking these three; they show that "per call" and "per minute" cannot be compared until you convert both to your own month.

For context only: Google Ads Keyword Planner estimates for the US, October 2026, put the average click for "legal answering service" at $380.11. That tells you how hard vendors compete for your decision; it is not what you will pay.

What does one month cost under each bill?

Illustrative: every number below is made up for an imaginary three-lawyer injury firm, and none comes from a client. The rates are invented too, not any vendor's. In one month the firm's line gets 120 calls to the service. Thirty are spam or wrong numbers and last about 1 minute each. The other 90 last about 5 minutes each. Of those 90, 14 book a consultation and 5 sign as cases.

Minutes: 30 × 1 + 90 × 5 = 480.

The cheapest bill here is the per-minute one, but change one input and that flips. If the 90 real calls ran 8 minutes each, the minutes become 30 + 720 = 750, the per-minute bill becomes 750 × $1.50 = $1,125 and the cost per signed case $225. The per-call bill stays at $960 ($192 a case), so a firm whose callers talk long should price per call. The per-appointment bill moves only with bookings. Repeat the table with your own call records, a rate from each vendor and the signed cases from your CRM.

What do the ethics rules ask when a nonlawyer picks up your phone?

What follows summarizes rule text. It is not legal advice, and I am not a lawyer. The ABA Model Rules are only a model: each state adopts its own version, and in Canada the provincial and territorial law societies set the rules, so read your own jurisdiction's text.

Model Rule 5.3 covers a nonlawyer retained by or associated with a lawyer. A partner or comparable manager must make reasonable efforts to ensure the firm has measures giving reasonable assurance that the person's conduct is compatible with the lawyer's professional obligations, and a lawyer with direct supervisory authority must make the same efforts about that person (ABA, checked 2026-10-12). Rule 1.6(c) adds that a lawyer must make reasonable efforts to prevent the inadvertent or unauthorized disclosure of, or unauthorized access to, information relating to the representation of a client (ABA, checked 2026-10-12).

Under Rule 1.18, someone who consults a lawyer about possibly hiring them is a prospective client, and even when no engagement follows, the lawyer may not use or reveal what they learned except as Rule 1.9 would permit for a former client (ABA, checked 2026-10-12). My practical reading, to run past your ethics counsel: a screener who collects only what a conflict check and a first booking need has less to protect, and less that could disqualify you.

For Canadian firms covered by PIPEDA, its first principle says an organization is responsible for personal information it transfers to a third party for processing, and must use contractual or other means to give a comparable level of protection (Office of the Privacy Commissioner of Canada, checked 2026-10-12).

What must survive the handoff so the call keeps its ad source?

A tracking number is a spare phone number that forwards to your real line and records which ad, listing or page the caller came from. The source survives only if the caller dials that tracked number and the service answers it. If your ad or directory listing shows the service's own number, the link between the call and the ad is gone before anyone speaks.

Keep your tracked numbers and point them at the service, then require four things on every call:

• the number the caller dialed
• the date and time
• an outcome: booked, not a case, wrong area, existing client or spam
• a place in your CRM, not only in the vendor's portal (how a law firm CRM stores the call and the outcome)

A call the service takes at 9pm and you return at 8am is still a lead from the ad that produced it. Record it as that source with the call-back delay noted, and do not log it as "missed". For a general reference on tracking numbers, see a plain-words guide to call tracking tools. In my own work I set up call tracking and attribution; I do not sell or resell any answering service.

What should the service tell you before it takes a call?

• Who writes the script, and can I change it myself the same day?
• Which questions do callers get asked about the other party, and can I limit them to what my conflict check needs?
• Does the service check names against my conflict list, or only record them for me to check?
• Can it answer in Spanish or another language I serve, and what does that add per call?
• Does it record calls, who holds the recordings, and how long are they kept?
• How does it mark a call that is not a case, and is spam billed?
• Can I cancel month to month, and when does the last bill stop?
• Will it work behind my tracked numbers, and can I test one call to each?
