Best Legal AI for Family Law: What to Pay For and What to Skip

For most small family law practices: pay for a business-plan general assistant for every fee earner, use the AI already inside your practice-management system, and add a research or drafting tool only if you research or draft from scratch every week. Skip standalone family-law chatbots, and delay an AI receptionist until you have measured missed calls.

That order follows cost per hour saved. Drafting and summarising are where family work spends its unbilled hours, and they cost the least to automate. Most legal-specific tools quote on request, and the few that publish figures change them, so the sums below are illustrative and no vendor quote is promised.

Seven recurring jobs and the tool that fits each

Read the table by columns, not rows. The general assistant is the only column that is "best fit" or "good" almost everywhere, which is why it is the first purchase. The other three columns each own one or two jobs, so each needs its own business case before you pay for it.

General assistants: the cheapest purchase that pays for itself

A business plan of ChatGPT or Claude costs $25 per user per month on monthly billing or $20 annually for the standard seat, with a two-seat minimum, and both say business content is not used for training by default. Microsoft 365 Copilot Business is $21 per user per month on annual billing. The point of a business plan is the data terms, not the model. Consumer plans have a training switch the user must turn off, which is not a control a practice can rely on.

If you were planning to build a custom GPT of your precedents, note that ChatGPT's custom GPT creation ended in late September 2026 and existing ones stop running on 11 December 2026. Use Projects instead: ChatGPT and Claude both offer shareable Projects on business plans, where you can store your letter templates and style rules once.

A sole practitioner hits the two-seat minimum on both business plans, which at the annual rate is $40 a month for two seats. That is still modest, and the second seat can go to an assistant or a part-time paralegal. The alternative is a consumer plan with the training switch turned off, which saves $20 a month and costs you the central control. For client material, I would pay the $20.

Here is a client-update prompt and an illustrative reply. Details are anonymised.

Draft an email to a client in a parenting-arrangements matter. Facts: the hearing has been adjourned to a date the court has not yet fixed; we need two documents from the client (last three payslips and a signed consent form) by Friday; do not predict any outcome or say what the other side will do. Tone calm, plain English, under 150 words, sign off [your name].

The reply was calm and the right length, and it asked for the two documents clearly. It also wrote "we are confident the court will take a sensible view once it has the full picture", which the prompt expressly ruled out and which a client could later quote back. I would delete that sentence and add the Friday deadline in bold. The rule that comes out of it: always list what the draft must not promise, and read the whole email as if the client will keep it.

AI inside your practice-management system: ask before you add

If your matters, time entries and documents already live in one system, its built-in assistant has an edge no outside tool can match: it sees the matter without anyone pasting anything. Clio's assistant is now called Manage AI (it was Clio Duo), and Clio also sells Clio Work, a research and drafting product that can use the documents, notes and deadlines already in Clio, links its research to the underlying authority and completes court forms. Clio's AI page says some AI features come with every plan, while AI legal drafting, AI billing and workflows need select plans or add-ons, and that admins can review an AI event log or switch AI features off. Check the plan comparison before you count any of it as free. Whatever system you use, put the same six questions to the vendor.

1. Which jobs does the assistant cover today: billing narratives, document drafting, matter summaries, intake?
2. Is it included in my plan, or an add-on priced per user?
3. Where does my data go, and is any of it used to train a model?
4. Can I switch it off for one matter, such as one involving a child's records?
5. Does it use my firm's own templates and wording, or only generic ones?
6. Can I see what it was given and what it produced, for the file?

A concrete before and after shows where built-in AI earns its keep. A time note reads "call w client re hearing, docs 0.4". An assistant working from the matter can expand it to: "Telephone attendance on client regarding adjournment of the hearing and the documents required before the next date; advised on next steps. 0.4." You still read it and amend it, but the 90 seconds of retyping disappear, and the narratives stop varying by who wrote them. The general guidance in using the AI already in your practice software applies here before any purchase.

Research and drafting tools: pay only if you research weekly

Thomson Reuters positions CoCounsel Legal for "every stage of a family law matter, from intake through trial", and its family law page names drafting of affidavits, declarations, motions and parenting-plan language from structured inputs, document review across large sets, and extraction of key events across texts, emails and depositions, plus research grounded in its Westlaw and Practical Law content. The page shows no prices. That is common in this category, so the buying question is a sum, not a comparison of list prices.

Say a research and drafting tool costs $150 per lawyer per month. That is a hypothetical figure, not a quote. At $90 an hour of lawyer time it pays for itself if it saves 1.7 hours a month per lawyer. A lawyer who researches a new point of law twice a week will clear that comfortably. A lawyer who works from precedents and rarely researches will not, and should skip it. The same sum works for any tool: monthly price divided by your hourly rate gives the hours you must save.

Whichever you try, keep one rule fixed: every citation is checked against the source before it goes in a document. A tool that links each statement to its source cuts the checking time. It does not remove it. A routine that works:

• Open each cited source and confirm it exists and says what the draft claims.
• Check it is still good law and in the right court's hierarchy.
• Confirm the quotation, not just the reference.
• Record who checked, so the file shows it.

Court form automation: repeatable, not generative

Form automation is a different kind of tool from the chatbots above. It takes a client's answers to a structured questionnaire and fills the same fields every time. Gavel Workflows, for example, turns intake answers into finished Word documents and PDFs, and its family law page describes client portals that collect information in divorce and custody matters, document generation, and uncontested matters offered online; its template library includes court forms. The pricing page says "Free to Start, Plans from $83" a month, which means a seven-day trial and then a paid plan, so budget for a subscription. The sibling tutorial on Gavel workflows versus generative AI goes deeper.

Here is a sum for when it pays. Suppose a standard pack (financial statement, parenting plan and cover form) takes 90 minutes to assemble by hand and 25 minutes once the client has answered the questionnaire. The practice does 8 packs a month. That saves 65 minutes each, or 520 minutes, about 8.7 hours a month. Building the template takes 14 hours once. In time alone it pays back in 14 ÷ 8.7, or 1.6 months. Add an $83 subscription and 2 packs a month look much worse: about 2.2 hours saved, worth $195 at $90 an hour, leaves $112 a month to repay $1,260 of building time, which takes about 11 months. At 8 packs the subscription barely matters, since $780 of time less $83 still repays the build in under two months. The break-even is repetition, not sophistication.

Summarising a statement bundle without trusting the summary

Bundles of bank and card statements are where an assistant earns its keep and where it can quietly lose something. The safe pattern is to ask for structured extraction and then check the totals yourself, instead of asking for a narrative summary you cannot verify. Use anonymised or redacted copies on a business plan, and keep the original documents out of the chat where you can.

Below is the text of 12 monthly statements for one account, with names removed. Produce a table of every payment out over $500: date, payee as written, amount. Then give the monthly total of those payments. Do not guess missing values; write "unclear" instead, and list any page you could not read.

Picture a practice that asked for a plain summary of a 120-page bundle and got a tidy paragraph about regular household spending. A paralegal who spot-checked page 61 found a monthly transfer of $1,200 to an account that was not on the disclosure form, and the summary had never mentioned it. With the table prompt above, that line would have appeared as a row. The routine that catches this kind of omission is short:

1. Ask for rows, not prose, so every item can be ticked off.
2. Add the monthly totals in a spreadsheet and compare them with the assistant's totals.
3. Open five pages chosen at random and match them to the rows.
4. Search the source for the largest payees to confirm none are missing.

That takes about 20 minutes on a 12-month bundle, and the fee earner still decides what matters. The point is not that AI cannot read statements. It reads most of them well, and the few lines it drops are the ones a spot check would catch if you did one.

Who gets the research seat first

Do not buy a research and drafting seat for everyone at once. Give one lawyer a trial seat for 30 days, with the rule that every citation is checked, and count the research tasks that lawyer did. If it was more than a handful a week, extend to the second lawyer. If it was two or three in the month, the general assistant and the research subscriptions you already hold were enough. A paralegal rarely needs the seat, and that choice alone keeps the monthly budget closer to the $75 line than the $375 one.

A three-person practice's budget, line by line

Take a practice with two lawyers and a paralegal and about 40 open matters. The monthly lines look like this. Figures are illustrative and use published list prices where a price exists.

Now the time side, with invented volumes for the general assistant and the built-in AI.

Allow 30 per cent for reading and correcting what the assistant produces and 22.1 hours becomes about 15.5. At $90 an hour of blended time that is roughly $1,392 a month against $75 of subscriptions, more than 18 times the cost. The research tool is a separate bet: its extra $300 needs 3.3 hours a month across the two lawyers to break even. If neither lawyer researches that often, the tool is the first thing to cut. Work through the practical drafting side in calm, consistent client emails with AI, and the document side in summarising financial disclosure safely.

What to skip for now

• A client-facing chatbot that answers legal questions. It risks giving advice the practice has not reviewed, to people who may be in crisis. If you want an AI front door, start with intake questions and triage, as in the intake questionnaire tutorial, with a person deciding what happens next.
• An AI receptionist, until you have measured. Count unanswered calls for a month and cost them. The calls are sensitive, so the design matters more than the price.
• Recording client meetings with a note-taker app. Meetings in family matters are intensely personal. Do not record without explicit consent, and check what your regulator and local law allow.
• Seats for people who will not use them weekly. Paid AI seats are per person, so the licence count matters.
• Annual or multi-year contracts before a 30-day trial.
• Any consumer plan for client material. The training switch is the user's job, and a practice cannot audit that.

Confidentiality rules that fit on one page

Family files hold children's details, health information, finances and allegations. The AI policy should be short enough that every person in the practice reads it. Here is a filled-in version to adapt, with your professional regulator's guidance and your insurer's requirements checked before it goes live.

AI use rule, [practice name]

1. Only firm-approved business accounts may be used with client material. No personal accounts.
2. Before pasting, remove names, dates of birth, addresses, school names and account numbers. Use "the client", "the other party" and "the child".
3. Never paste medical, safeguarding or allegation material into an assistant without partner approval.
4. Every AI draft is read in full by the fee earner before it leaves the practice. The fee earner is responsible for it.
5. Every legal citation is opened and checked against the source, and the check is noted on the file.
6. No recording or transcription of client meetings without the client's written consent.
7. Incidents (wrong recipient, pasted material, a suspected error) are reported to [name] the same day.

Rules 2 and 3 do most of the protective work, because they limit what could leak if a tool misbehaves. Rule 4 keeps responsibility where your regulator will look for it. If you are choosing between tools on privacy grounds, the checklist in what a small family practice should check before buying goes through the contract terms line by line.

A 30-day trial before any contract

Run the cheapest option first and add one tool at a time, so you can tell which one saved the time.

The deciding numbers are hours saved after review, errors caught before sending, and whether the people using it want to keep it. If the answer to the first is under two hours a person a month, the seat is not paying for itself yet. Before any wider rollout, cost a paid seat on every desk against the hours each person actually saved in the trial, not against the vendor's estimate.

Last point on timing. Vendors rename and re-price legal AI often, and several of the names above changed within the last year. Keep a one-page record of what you tested, the date, the plan and what you were quoted. That record is your protection against marketing claims, and your starting point when someone proposes a replacement.

Family law AI: questions small practices ask

Is a general assistant enough for a family law practice?

For drafting client emails, summarising bundles and building chronologies from documents you supply, a business-plan assistant covers most routine work at low cost. It is not enough for research that must cite authority, because general chatbots can invent citations. Add a research tool only if you research often, and check every citation against the source.

Which family law AI tools publish their prices?

Few legal-specific tools publish full prices. Thomson Reuters's CoCounsel family law page showed none when I read it, and Clio says some AI features come with every plan while AI drafting, AI billing and workflows need select plans or add-ons. Gavel does publish figures: $160 a month per user for Gavel Exec contract review, and document automation plans from $83 a month after a free trial. Ask for written quotes.

Can I paste client documents into ChatGPT or Claude?

Only on a business plan where content is not used for training by default, and only after checking your regulator's guidance and your engagement letter. Consumer plans have a training switch you must turn off yourself. Anonymise names, dates of birth, addresses and children's details first, and never paste anything you would not show a third party.

Should a small practice buy an AI receptionist first?

Not first. Measure how many calls go unanswered and what an unanswered call costs before you pay for one, since many family law callers are in distress and need careful handling. Start with the cheaper wins in drafting and summarising, then revisit the receptionist with data from your own phone log.
