Family Law Retainer Agreements: AI Drafts, Lawyer Sign-Off

AI can draft a family law retainer clause by clause from your own template, but a lawyer must still check scope, fee wording, funds held for the client, conflicts, termination and any AI-use disclosure before it goes out. Treat the AI as a fast first drafter and the lawyer as the only approver.

The temptation is to ask a chatbot for "a family law retainer" and send the result. Resist it. A generic draft has no idea what your firm bills, what you will and will not do, which rules your jurisdiction applies to fee agreements, or what your clients tend to misunderstand. The method below keeps your template as the source and uses AI for the slow bits: tailoring the scope to the matter, tightening plain-language wording, and producing a summary page a client can read in two minutes.

One caution. This is a drafting workflow, not legal advice. Fee agreements, client money and professional conduct are regulated, and the rules differ widely, so your regulator's guidance and your own ethics adviser decide what is required.

Start from your template, not from a blank prompt

The best input is a retainer your firm already uses and trusts. The AI's job is to adapt it, not to invent it.

1. Pick the master retainer and strip the client details, so it has placeholders such as [client name], [matter], [hourly rates] and [initial deposit].
2. Label each clause with a heading and a one-line purpose, which becomes the structure the AI works to.
3. List the fields that change per matter: type of matter, whether children are involved, fee basis, deposit amount, who is on the team.
4. Write down your non-negotiables: wording the AI must not alter, such as fee-agreement formalities and funds-held clauses.

Then ask the AI to produce the matter-specific version while leaving the non-negotiables untouched, and to mark every place it changed or added text. That last instruction is what makes review fast, because the lawyer reads the marked changes, not 5 pages of familiar text.

Clause by clause: what AI drafts and what the lawyer decides

Scope wording: where family retainers go wrong

The scope clause prevents most client disputes and is the one most worth the AI's help, because specific lists are laborious to write. Compare two versions.

Vague: "The firm will represent the client in connection with the divorce."

Specific (illustrative): "We will advise you on the arrangements for your children and the division of property following separation. We will prepare and file the application for [type], correspond with the other party's lawyer, and attend up to [number] hearings. We will not represent you in an appeal, in any criminal matter, or in tax or immigration advice. If a new issue arises, we will tell you and agree in writing whether it is covered."

The second tells the client where the edges are and gives you a basis to discuss extra work. Ask the AI to turn your matter notes into this form, with an explicit "not included" list and a rule for new issues. Then the lawyer checks that every included task is something the firm will actually do for the stated fee basis.

Fee wording the client can follow

Fee clauses tend to be dense, and in family matters clients are often paying from limited funds. AI is good at rewriting a rate card into plain English, as long as the numbers are given to it and checked afterwards.

Illustration. The template says: "Fees are charged on a time basis at the hourly rates in Schedule A, in six-minute units, plus disbursements." A plain rewrite: "We charge for the time we spend on your matter. Rates are in the table on page 4. We record time in six-minute blocks, so a short call is charged as one block. Costs paid to others on your behalf, such as court fees, are added at the cost we pay." Then a worked line for the client: "A 30-minute call with a lawyer at [rate] an hour costs [amount]." The lawyer replaces every placeholder with the real figures and checks the six-minute rule is how the firm really bills.

Do not let the AI generate figures. It should only format the ones you give it, and it should leave a visible placeholder if a number is missing. A confident invented rate in a client document is exactly the kind of error that gets a firm into a complaint.

The AI-use disclosure clause

Some clients now ask whether their lawyer uses AI. A short clause answers that and sets expectations. What it says depends on what your firm really does, so write your policy first and draft the clause from it. An illustrative version:

Use of technology. We may use AI-assisted tools to help draft documents, summarise material and organise your file. We do not use your information to train public AI models. A lawyer at the firm reviews all work before it is sent to you or filed. If you would like us not to use AI tools on your matter, tell us and we will discuss what that means for the way we work.

Check each sentence is true before it goes in. "We do not use your information to train public AI models" is a promise: confirm it against each vendor's current terms and settings. "A lawyer reviews all work" must match your real process. And the last sentence invites an opt-out, which you may or may not want to offer, so decide deliberately. Our tutorial on what to pay for in family law AI covers what to look for in a tool's data handling.

A three-lawyer firm's retainer, drafted and checked in 25 minutes

Illustration only. Say a three-lawyer firm takes a new client with a parenting-arrangements matter and a possible property settlement. The firm's master retainer runs to five pages.

The lawyer enters the matter fields into the firm's system: matter type, fee basis (hourly, with a $[deposit] deposit), and the team. The system fills the placeholders. The lawyer then pastes the scope paragraph from the template with the matter notes, minus the client's name and identifying details, into an approved AI tool with this prompt:

Here is the scope clause from our family law retainer template and a short description of the matter (no names). Rewrite the scope clause for this matter in plain English. Keep any text in [square brackets] unchanged. List what is included and what is not included. Add one sentence saying new issues will be discussed and agreed in writing. Mark every sentence you changed or added with (CHANGED).
Matter: parenting arrangements for two children; possible property settlement; no court proceedings yet; other party has a lawyer.

The tool returns a clear draft with two (CHANGED) marks. What the lawyer fixes: the AI listed "mediation attendance" as included, which the firm bills separately, and it called the matter a "divorce" although the couple were never married. Both are errors a careful read catches and an unchecked send would not. The lawyer corrects them, drafts the fee and funds clauses herself from the template, and asks the AI for a one-page summary at the top.

The summary, illustrative: "What we will do: advise on arrangements for your children and a possible property settlement. What it costs: hourly rates on page 4; we ask for a deposit of [amount] before we start. What we need from you: documents within 14 days of asking. How to reach us: email or phone; we aim to reply within [period]. How to end this: tell us in writing at any time." Total time: about 25 minutes, of which the lawyer's review was around 15.

Other drafting jobs AI does well in a retainer pack

A plain-language cover email

Ask for a short email that says what is attached, what the client must do, and by when. Illustration: "Hi [first name], please read the attached agreement and the one-page summary. If it looks right, sign page 6 and return it with the deposit so we can start. If anything is unclear, call me before you sign." The lawyer checks the instructions and the deadline.

A client responsibilities checklist

Turn the dense clause into a bullet list: give us complete and honest information; send documents promptly; tell us if your contact details or situation change; do not discuss the case on social media; keep copies of everything you send. The lawyer confirms that each item is something the firm wants to rely on.

A scope-change letter

When a matter grows, you need a short variation. Give the AI the original scope and the new task and ask for a one-paragraph addendum with a placeholder for the cost estimate. The lawyer sets the estimate and checks the wording against the original.

A termination and file-return explanation

A client-facing explanation of what happens to the file and any unused deposit if either side ends the relationship. The wording must reflect your jurisdiction's rules on funds and files, so the lawyer decides every sentence.

Errors AI makes in retainer drafts, and how each one shows up

After reviewing enough drafts you start to see the same slips. A reviewer who knows them reads faster.

• The silent clause rewrite. You asked for the scope to change, and the termination clause came back reworded. It shows up in a redline against the template, not in the marked changes. Always compare.
• Invented specifics. "Responses within 24 hours", "a fixed fee of $2,500" or "unlimited calls" appear although you never supplied them. Search the draft for every number and check it against your source.
• Matter-type drift. The tool says "divorce" for a separation, "custody" where your rules use a different term, or "spouse" for a partner who was never married. Read the opening paragraphs for words that do not match the matter.
• Over-promising. Phrases such as "we will ensure", "we guarantee" or "we will protect your interests" create duties you did not intend. Replace them with "we will advise" and "we will act on your instructions".
• Dropped exclusions. When asked to shorten, the tool trims the "not included" list first. Keep it.
• Tone mismatch. Plain-language rewriting can drift into breezy language that sounds casual about serious things such as children and money. Read it as the client would on a bad day.

Before and after: a termination clause in plain English

A template might say: "The client may terminate this agreement at any time by written notice. The firm may withdraw in accordance with its professional obligations. On termination the client shall pay all fees and disbursements incurred to the date of termination."

A plain-language version the AI might produce (illustrative): "You can end our agreement at any time by telling us in writing. We may stop acting for you only where our professional rules allow, and we will give you reasonable notice and help you move your file. If we stop, you pay for the work done up to that point, and any money you paid in advance that we have not used will be dealt with as set out on page 3."

What the lawyer checks and may change: whether "reasonable notice" is something the rules and the firm's practice support, whether "help you move your file" commits the firm to more than it does, and whether "dealt with as set out on page 3" correctly points at the funds clause. The plain version helps the client. It does not replace the check.

A prompt for the one-page summary, with sample output

A summary page is where AI adds the most value, because lawyers rarely have time to write one. Give it the final approved text, not the draft.

Below is a family law retainer agreement, final and approved. Write a one-page plain-English summary for the client with these headings: What we will do, What we will not do, What it costs, What we need from you, How to reach us, How to end the agreement. Use only facts in the agreement. Do not add or change any number or date. If something is not in the agreement, write "see section [number]". Keep it under 250 words and use short sentences.

Illustrative output for "What it costs": "We charge for our time at the rates on page 4, in six-minute blocks. We ask you to pay [amount] before we start. Court fees and similar costs are extra and are charged at cost." What you would fix: if the tool wrote "about $[amount] in total", that is an estimate the agreement does not contain, so delete it. The reviewing lawyer reads every line of the summary against the full terms, because clients tend to read the summary and not the rest.

Limited-scope and fixed-fee matters

Not every family matter fits an open-ended hourly retainer. Some firms offer a limited-scope service, such as reviewing a settlement agreement, preparing one document or attending a single hearing. For those, the retainer changes shape.

• The scope clause lists the single task, and says clearly that the firm is not acting on the rest of the matter.
• The fee clause states the fixed fee or estimate and what would take it outside the fixed fee.
• A "what happens next" sentence says the client is responsible for the other steps unless you agree in writing to take them on.

AI can generate these variants quickly if you keep a short library of approved clauses for each service type and tell the model to use only those. The risk is that a fixed-fee client believes you are handling everything. Put the exclusions at the top of the summary page, not buried in clause 14, and have the lawyer read that part twice.

When a client asks about your AI policy

Once your retainer mentions AI, some clients will ask. Prepare a short, honest answer so it does not depend on who picks up the phone. A useful version has four parts: which kinds of tasks the firm uses AI for, such as first drafts of documents and summaries; what is never done with it, such as entering client names into public tools; that a lawyer reviews and takes responsibility for all work; and what the client can do if they would prefer the firm did not use it on their matter. Keep it to a paragraph and put it in the same place as your privacy information. Review it whenever the tools change, because the answer is only worth giving if it is current.

The lawyer's review checklist before anything is sent

1. Names, matter type and dates correct, and consistent between the summary and the full terms.
2. Scope matches what the firm will actually do, with exclusions clearly stated.
3. Every fee, rate, deposit and billing unit matches the current schedule, and none was invented by the tool.
4. The funds-held clause is the firm's approved text and complies with the applicable rules.
5. The AI-use clause is true, matches policy, and does not overpromise on data use.
6. Conflicts, confidentiality and termination clauses are the approved wording.
7. The summary page agrees with the full text on every number and date.
8. Marked changes were each read, and nothing outside the marks changed (compare with the template using a document comparison).
9. No client names or sensitive facts were put into an unapproved tool.
10. A lawyer's name and the date are recorded as the approver on the matter file.

The comparison step is easy to skip and valuable. Models sometimes reword a clause you told them to leave alone. A redline against the template shows it in seconds.

How to tell the process is working

Track three simple things for a month. How long a retainer takes from intake to sent, in minutes. How many corrections the reviewing lawyer makes per draft, and which clauses they fall in. And how many clients come back with questions about scope or fees, which tells you whether the plain-language rewriting is helping. If corrections cluster in one clause, fix the instruction or take that clause back from the AI. If the review is taking longer than drafting by hand, the process needs simplifying.

For the stage before this, see our tutorial on AI intake and urgency triage for family law, and for what happens after signing, calm and consistent client emails. If you want help mapping the drafting workflow for your own firm, get in touch, and your regulator's rules will remain the authority on what the retainer must say.

Questions about AI-drafted retainers

Can AI draft a family law retainer on its own?

It can produce a usable first draft from your firm's template and instructions, but a lawyer must review and approve every retainer before it goes to a client. Fee rules, scope limits and required disclosures are professional obligations, and the AI does not know which rules bind your firm.

Should the retainer mention that the firm uses AI?

A short clause saying what AI tools may be used, how client data is protected and that a lawyer reviews all work is a sensible addition. Whether disclosure or consent is required depends on your professional rules and your clients' needs. Ask your regulator or ethics adviser, and write the answer into the clause.

Which parts of a retainer should never be left to AI?

Anything that reflects a legal or ethical rule: how funds held for the client are treated, fee-agreement formalities, conflicts, termination rights and limits on the lawyer's liability. AI can suggest wording, but a lawyer must decide and own it.

Is it safe to paste a client's details into an AI tool to draft the retainer?

Avoid it. A retainer draft needs the template and the structure, not the client's life story. Use placeholders for names and facts, fill them in your own system, and check the tool's data handling before putting any real client information into it.

How long should a retainer be?

Long enough to cover scope, fees, responsibilities and ending the relationship, and short enough that a stressed client reads it. A plain-language one-page summary on top of the full terms helps, as long as it agrees with the full text on every number and date.
