AI Document Review for Family Law: What Claude Can Do Safely

The Short Answer

AI document review for family law means using a model like Claude to do the first pass on three kinds of material that dominate a family practice: financial disclosures (organize, cross-check, flag inconsistencies), message exports in custody disputes (build a dated chronology with quotes and citations), and intake notes (turn them into a draft parenting plan). Claude does each well when the prompt is structured and the confidentiality rules are respected, and the lawyer verifies every figure, quote, and provision before it goes to a client or a court.

The phrase "client intelligence for family law" has started appearing in vendor marketing, and it mostly describes the same three tasks packaged into a platform. This post describes how to do them with Claude on a plan you already have, what the output looks like, and, because family files contain children's information and often sealed material, what you may and may not upload. If you are new to Claude in a family practice, the family law practice page is the overview; this post goes deeper on document review specifically.

Why Family Law Is Different for AI Review

A commercial contract has parties who chose their words. A family file has bank statements the other side would rather you not read closely, thousands of text messages written in anger, and a child whose information is protected by rules that do not apply to a corporate borrower. Three consequences follow for AI review.

• The documents are evidence, not agreements. The task is rarely "what does this say" and usually "what does this show, and where." Every output needs a citation back to the page, the statement line, or the message timestamp so it can be verified and, if needed, authenticated.
• Volume is uneven. A single message export can run to tens of thousands of lines. That is where a model's ability to read everything without skimming matters most, and also where it is most likely to summarize instead of cite unless told otherwise.
• Confidentiality has extra layers. Model Rule 1.6 applies as it does everywhere, and on top of it sit rules specific to family and juvenile matters: court files that are sealed or confidential by statute, children's identifying information, protective orders, and in some cases mental-health or substance-abuse records with their own statutory protection. The tools are the same as in other practice areas; the pre-upload checklist is longer.

Task 1: Financial Disclosure Analysis

The opposing party's sworn financial affidavit arrives with bank statements, pay stubs, and a tax return. The question is whether the numbers agree with each other. Claude's job is to extract the figures from each document into one place and lay them side by side so the disagreements show.

What to ask for: an inventory of every document received with dates; a table of reported income, assets, debts, and monthly expenses from the affidavit with page references; the same figures as evidenced by the supporting documents (deposits by month from the statements, gross and net from the pay stubs, adjusted gross income from the return); and a discrepancy list ranked by dollar size and by how directly it contradicts the sworn figure. Then a discovery follow-up list: which interrogatories, requests for production, or subpoenas each discrepancy justifies.

What the output is: a set of leads. "Deposits exceed reported income by a monthly average of X" is a reason to subpoena the account the transfers came from, not a fact for the judge. The full prompt sequence, with the cross-checking step and the deposition-question step, is the financial disclosure analysis workflow.

The confidentiality wrinkle: financial disclosures in many jurisdictions are filed under seal or are confidential by court rule, and they contain account numbers and Social Security numbers. Redact account numbers to the last four digits and remove SSNs before uploading; the analysis does not need them. Use a commercial tier of Claude that does not train on inputs.

Task 2: Message-Export Chronologies in Custody Disputes

A custody dispute produces a text-message export, sometimes a co-parenting-app export, that both sides will mine for the same incidents. The lawyer's problem is finding the twenty messages that matter in ten thousand that do not, and presenting them in an order a judge can follow. This is the task where Claude's value is largest and where the prompt discipline matters most.

What to ask for: a chronology table with columns for date and time, sender, exact quoted text, the topic it relates to (exchange logistics, missed parenting time, a safety concern, a schedule change request, the child's health or school), and a message identifier or line number from the export. Then a second pass: for each topic, a list of every message in that thread in order, so the pattern (or the absence of one) is visible. Then a gap list: periods with no messages, which may indicate a different channel was used.

The two rules that make it usable: quote, do not paraphrase, and cite every row to the export. A paraphrased chronology cannot be checked and cannot be used. A quoted one with line references can be verified in minutes and turned into an exhibit. Ask Claude explicitly to include messages that cut against your client on each topic; a chronology built only from the helpful messages is one the other side will complete for you in court. The general method is in the case chronology workflow; custody exports just add the topic column and the both-sides rule.

The confidentiality wrinkle: message exports name children, often include photographs, and may reference medical or school information. Replace the children's names with initials or role labels (Child A, age 9) before uploading, strip attachments and images unless a specific one is at issue, and check whether any order in the case restricts disclosure of the messages themselves. If a guardian ad litem or custody evaluator has been appointed, check whether their reports are confidential by statute before they go anywhere near a model.

Task 3: Parenting Plans From Intake

A parenting plan is drafted from facts: the children's ages and school, both parents' work schedules, geography, the conflict level, and any safety concerns. Claude can turn structured intake into a complete draft with legal decision-making, a regular parenting-time schedule, holiday and break allocation, exchange logistics, and communication rules, then add high-conflict provisions where the intake calls for them and localize to your state's statutory factors.

What to ask for: the intake laid out in one structured message; a full draft plan with each section labeled; a regular weekly schedule expressed as a calendar-ready grid; bracketed flags on every provision that depends on a state statute or a client decision; and a plain-English summary for the client. The step-by-step prompts are in the parenting plan workflow. Where the intake indicates domestic violence, substance concerns, or a history of withholding, ask for the protective provisions (supervised exchange, third-party locations, communication through a monitored app) as a separate section so you can include or omit them deliberately.

What Claude does not know: your state's best-interests factors, the local court's standard schedule templates, whether the judge in this division prefers a specific format, and what your client will actually accept. The draft is a starting point for a conversation with the client, not a document that goes to the other side unread.

The Confidentiality Rules That Decide What You Upload

This section is the one to reread before each upload. The rules below are general; your state and your judge control.

• Children's identifying information. Most family and juvenile procedural rules restrict publication of children's names and identifying details, and many court systems require initials in filings. Apply the same standard to a model: initials or role labels, ages rather than birthdates, no school names unless the school is the issue. Claude does not need the child's name to build a chronology or a parenting plan.
• Sealed and confidential material. Financial affidavits, custody evaluations, guardian ad litem reports, mental-health and substance-abuse records, and anything filed under a protective order may be restricted from disclosure by statute, rule, or order. "Disclosure" to a third-party service is a question your rules and any order answer; read the order, and when it prohibits disclosure to anyone other than the parties and counsel, do not upload. Redacted summaries in your own words are usually safe where the document itself is not.
• Consumer versus commercial tiers. Client work belongs on Claude Team or Enterprise, which do not train on inputs by default, not on Free or Pro. This is the plan-level rule that governs every practice area, and it is non-negotiable in one where the file includes a child's medical history.
• Informed consent and disclosure. ABA Formal Opinion 512 addresses when a lawyer needs informed client consent to use a generative-AI tool with confidential information, and family clients in particular may have views about their children's information. The disclosure guide and the ethics guide cover the analysis; the short version is that a sentence in the engagement letter and a conversation are cheap, and a surprised client is not.
• Opposing-party data. The other side's disclosures and messages are in your possession under discovery rules, which often carry their own use restrictions. Confirm the protective order or local rule permits the use before uploading.
