Notaries: using AI on deeds without breaching confidentiality

In a notary office, every file carries names that bind families across several generations. A grant of probate after a death, a deed of gift split between siblings, a sale agreement: these documents bring together the parties' full civil status, their lineage and a detailed picture of their assets. Pasting such a text as-is into a consumer AI assistant would expose all of it to a server you do not control. Yet AI saves real time on drafting and review. The right approach is to let it work on the structure of the deed, never on the identity of the people involved.

The data most exposed in a deed

The full civil status of the deceased and the heirs (birth names, dates and places, lineage), the parties' contact details, the cadastral references and addresses of the assets, and the amounts: sale price, balancing payments, value of the estate, allotted shares. These are exactly the elements that must be pseudonymized. The structure of the authenticated deed, its standard clauses and its references to the Civil Code are not confidential and can flow freely to the AI.

Summarize or draft a deed without seeing the parties

In practice, you pseudonymize the deed before sending anything: surnames become consistent pseudonyms, amounts and addresses are neutralized. The AI then summarizes a complex estate, drafts a gift template or checks a clause on that masked version. You re-identify the result locally afterwards, on your own machine. At no point does a client's name, an heir or the value of an asset leave the office. The notary's professional secrecy, which covers the identity of the parties as much as the content of the deeds, stays intact.
