AI for business · Industry guide

⚖️ AI rules: Lawyers, accountants, consultants

Mostly minimal-risk AI use — but professional secrecy and client data make GDPR and confidentiality the main issue.

Typical AI uses and their risk level

Minimal
Drafting contracts, letters and memos

Minimal; a professional checks every output; beware of invented case law.

Minimal
Analysing client documents with AI

Only in tools with a DPA and no training on data — or pseudonymise first.

Minimal
Bookkeeping automation (invoice reading)

Minimal; DPA with the provider.

High risk
Tools that assist courts in interpreting law

High risk (Annex III, point 8) when used by or for judicial authorities.

What to do

  • Agree with clients whether and how AI is used on their files.
  • Use business plans or local tools; pseudonymise documents.
  • Verify every citation and figure.

Common pitfalls

  • Professional secrecy is broken if client files go to a tool that uses them for training.

Examples
