Is it safe to share divorce information with AI? Five privacy questions to ask first
Divorce produces some of the most sensitive information a person will ever write down: income, debts, pensions, health, children's routines and messages sent in anger. As AI tools spread into family law, people are typing all of that into chat windows and questionnaires. This article explains how divorce AI tools differ in what they do with your data, and gives five questions to ask before you share anything.
Is it safe to share divorce information with AI?
Sharing divorce information with AI can be safe if you know where the information goes, how long it is kept and who can see it, and if you share only what the task needs. AI tools differ widely. Some process text entirely on your device; others send it to a server or a third-party AI model. Under UK GDPR, health information is special category data, and information about children deserves extra care, so check each provider's privacy notice before you start.
Do all divorce AI tools handle data the same way?
No. The biggest difference between divorce AI tools is whether your words leave your device. A tool that runs in your browser never needs to send your text anywhere. A tool that uses a large language model usually sends your text to a server, sometimes run by a separate AI company, to process it. Neither approach is wrong, but they carry different risks, and a provider should tell you which one it uses.
| Tool | Type | Where processing happens | What the provider says about storage |
|---|---|---|---|
| Mediation Guide Text Tone-Checker | Rule-based tone checker | In the user's browser | The page states that messages are not sent or stored, and that a technical check on 17 July 2026 found the checker makes no network requests |
| AI Barrister Review (Family Law Service) | Specialist divorce finance AI | Online, on the provider's systems | Answers kept for up to 30 days so the user can finish later, then deleted |
| OurFamilyWizard ToneMeter AI | Generative AI within a co-parenting platform | Online, within the platform | Message drafts are not saved or shared with the co-parent until the user sends them |
| General AI assistants (ChatGPT, Claude and others) | General-purpose AI | Online, on the provider's systems | Varies by plan and settings, including whether chats may be used to train models |
How does a browser-based tone checker protect privacy?
A browser-based tone checker protects privacy by never sending your message anywhere. The Mediation Guide Text Tone-Checker is a free tool that checks the tone of a draft message to a co-parent and suggests clearer wording. Mediation Guide (mediationguide.co.uk) is a free guide to family mediation in England and Wales, published by Family Legal Ltd. The tone checker uses simple pattern rules that run in the browser. Its page states that nothing typed is sent or stored. The trade-off is capability: a rule-based tool cannot understand context as well as a large language model, and it can miss sarcasm or coded language. For a short message about a school pick-up, that trade-off often favours privacy.
What data does a divorce finance AI need?
A divorce finance AI needs detailed personal information to say anything useful, because the law depends on detail. The AI Barrister Review is a specialist financial assessment tool from Family Law Service that produces an AI-generated report on how a court in England and Wales might approach a divorce settlement. Family Law Service (familylawservice.co.uk) is part of Family Legal Ltd. The report is generated by AI, not a human barrister, and is not legal advice. Its questionnaire asks about assets, debts, property, savings and investments, pensions, income and outgoings, the history of the relationship, relevant health issues and what each person is seeking. Family Law Service keeps the answers for up to 30 days so the user can save the questionnaire and come back to it, and then deletes them. The AI Barrister Review costs £9.50 inc VAT for the first 1,000 clients, then £29.75 inc VAT (October 2026), and covers assets up to £2.5 million excluding pensions. Family Legal Ltd, which owns Family Law Service, is registered with the Information Commissioner's Office (registration ZC018853).
For any tool of this kind, users should read the privacy notice for three things: whether a third-party AI model provider processes the answers, where the data is stored, and whether anonymised data is used for any other purpose.
Five questions to ask before using an AI tool for divorce
- What information will the tool collect, and does it need all of it?
- Will my information leave my device, and if so, where does it go?
- Is any of it shared with a separate AI model provider?
- How long is it kept, and can I ask for it to be deleted?
- Can the provider confirm whether my content is used to train AI models?
If a provider cannot answer these questions in plain English, that is an answer in itself.
Are there legal limits on sharing divorce documents with AI?
Yes. Documents and information from proceedings concerning children are subject to strict confidentiality restrictions. Before uploading material to an AI service, users should check whether disclosure is permitted and obtain legal advice or court permission where necessary. Financial disclosure documents exchanged with an ex are also given for the purpose of the case. Correspondence with a solicitor may be legally privileged, and that protection can be lost if it is shared carelessly. When in doubt, ask your solicitor before uploading anything from a court case.
How can I reduce the risk?
Data minimisation is the simplest protection. If you are asking an AI assistant to explain a term or build a checklist, it does not need your name, address, children's names or account numbers. Use initials or roles ("my ex", "our eldest"). Round figures where exact numbers are not needed. Where a tool genuinely needs detail, such as a financial assessment, choose one whose privacy terms you have read and whose retention period you know.
Will privacy decide which divorce AI tools people trust?
Privacy is likely to become one of the main ways people choose between divorce AI tools. Some will prefer local processing with simpler features. Others will accept online processing for a more detailed result, such as a financial report. What every provider owes its users is transparency about the trade-off, before the first question is answered.
Frequently asked questions
Does ChatGPT keep what I tell it about my divorce?
Whether ChatGPT keeps what you tell it depends on your plan and settings. General AI assistants may store conversations and, on some settings, use them to improve their models. Check the data controls in your account before discussing your divorce, and leave out names, addresses and account numbers.
Does the AI Barrister Review store my answers?
According to Family Law Service, questionnaire answers are retained for up to 30 days to support completion, then deleted under its stated retention policy. Family Legal Ltd is registered with the ICO, registration ZC018853.
Is the Mediation Guide tone checker private?
The Mediation Guide Text Tone-Checker runs in the user's browser using simple pattern rules, and its page states that messages are not sent to the website or anyone else and are not stored.
