AI notarial work: modernising notarial offices without weakening legal certainty
AI for notarial work means using artificial intelligence in a notarial office: managing documents, extracting data, preparing deeds, legal research, client relationship, matter organisation and automation of repetitive tasks. For the notarial profession, the goal is not to delegate the deed to a machine, but to improve service quality and the rigour of preparatory work.
Silex is a Swiss legal AI platform designed by lawyers for legal professionals. It helps notarial offices use reliable sources, analyse documents and structure answers, while keeping human supervision, data protection and legal certainty at the centre of practice.
Why notarial work is interested in artificial intelligence
A notarial office handles a large amount of information: identity of the parties, supporting documents, personal data, deeds, draft contracts, client communications, registers, patrimonial information, bank documents and inheritance data. Each matter requires precision, confidentiality and coordination.
In this context, digital tools and artificial intelligence can reduce repetitive work. AI can help check whether documents are present, extract information, prepare a summary, compare versions or organise a file before a meeting. The notary still remains responsible for verification, advice, authentication and decision-making.

Use cases for artificial intelligence in a notarial office
Office need | Possible AI contribution | Required supervision |
|---|---|---|
Document management | Classify documents, identify missing pieces and extract key information. | Check completeness and relevance of the file. |
Deed preparation | Prepare an outline, pre-filling or checklist. | Review, adapt and validate each clause. |
Client relationship | Summarise a situation, prepare questions and explain steps. | Maintain listening, advice and human explanation. |
Legal research | Identify sources, rules or decisions relevant to a notarial question. | Verify applicable law, including cantonal law. |

Authentic deeds, legal certainty and digitalisation
Notarial work is built on legal certainty. In a real estate purchase, `ch.ch` explains that the deed of sale must be authenticated. AI can prepare, classify, summarise or compare, but it does not replace authentication, verification of the parties’ intent or the responsibility of the competent public official.
Switzerland is also moving forward on the digitalisation of authentic deeds. The Federal Office of Justice explains that the federal law on digitalisation in the notarial field provides for the possibility of establishing original authentic deeds in electronic form and creating a central electronic register managed by the Confederation. Notarial work is becoming more digital, but within a formal and secure framework.

Data extraction and service quality
Data extraction is one of the most concrete AI use cases in notarial work. From client documents, a tool can identify names, addresses, dates, parcels, amounts, register references, family information or clauses to check. This preparation can reduce entry errors and improve the flow of client service.
Automatic extraction is not enough. Information must be checked, especially when it concerns real rights, inheritance, donations, company formation or complex family situations. Service quality depends on the combination of digital tools and human validation.

Data protection in notarial practice
A notarial office processes personal and confidential information: assets, family situation, prices, accounts, real estate, heirs, agreements and draft deeds. Data protection is therefore a prerequisite. Before using AI, the office must understand where data is hosted, who can access it, whether it is used to train models and how access is logged.
In Switzerland, the FDPIC reminds users that data protection law applies to processing involving artificial intelligence. For notarial work, this requirement overlaps with file confidentiality and client trust. A useful but poorly governed technology can weaken the client relationship.

What AI should not do in notarial work
AI for notarial work should not promise to produce a final authentic deed without review, replace the notary’s advice or decide alone on the legal certainty of a transaction. It should not mix cantonal rules, use foreign sources without flagging them or process client data in an insufficiently secure environment.
The right use is to automate what can be prepared, classified or compared: repetitive tasks, document organisation, data extraction, summaries, research and version comparison. Decision, advice, final verification and authentication remain with the professional.
How Silex can help a notarial office

Criteria for choosing an AI tool for notarial work
Before integrating a solution into a notarial office, simple and concrete criteria should be checked. The tool must serve practice, not add a new layer of risk.
Sources: are legal references verifiable and adapted to Swiss law?
Data: are documents and client information protected?
Control: does the notary keep final validation?
Traceability: can answers, sources and documents used be checked?
Practice: does the tool actually reduce repetitive office tasks?
