Legal position

Are law firms allowed to use AI?
§203 StGB explained.

The short answer: yes — but not with every tool. Lawyers are bound by professional confidentiality under §203 StGB. Anyone who, without authorisation, discloses another's secrets entrusted to them in their professional capacity commits a criminal offence — punishable by a fine or imprisonment of up to one year. Crucially: passing client data on to an IT service provider can also constitute such disclosure.

This is exactly where common AI services fall short: the moment you enter client data into ChatGPT, you transmit protected secrets to an external provider. §203 (3) StGB permits the involvement of assisting persons only where they have been formally bound to confidentiality (§203 (4) StGB). Standard AI subscriptions provide no such obligation. On top of that comes the US CLOUD Act.

ClapNClaw was built for exactly this scenario. Your firm receives its own isolated container on servers in Frankfurt. An AVV (data processing agreement) under Art. 28 GDPR is included from day one. The Compliance plan (€59 per user/month, €50 annually) adds a written §203 StGB supplementary agreement — the formal confidentiality obligation, backed by technical safeguards.

Note: this overview is not a substitute for legal advice — it describes how ClapNClaw addresses the requirements of §203 StGB on a technical and contractual level.
