Can WhatsApp messages be used as evidence in German courts? Yes. German courts accept WhatsApp messages as evidence under ZPO §371 (visual inspection of electronic documents). The key is that messages must be properly preserved, authenticated, and processed in compliance with GDPR. This guide explains the legal requirements, common pitfalls, and how to prepare your WhatsApp evidence for German courts.
Are WhatsApp Messages Admissible in German Courts?
Yes. German courts admit WhatsApp messages as evidence in civil, criminal, and labor proceedings. The legal basis is ZPO §371, which governs visual inspection evidence for electronic documents.
German courts apply the principle of freie Beweiswürdigung (free evaluation of evidence) — the judge decides independently how much weight to give WhatsApp messages. There's no fixed rule that automatically classifies WhatsApp as "valid" or "invalid."
Admissibility depends on four factors:
- Authenticity: Proof that messages are genuine and unaltered
- Relevance: Direct connection to the disputed matter
- Lawful acquisition: No violation of personality rights or other fundamental rights
- Chain of custody: Documentation from export to court presentation
For a comparison across jurisdictions, see our admissibility guide by country.
How to Preserve WhatsApp Evidence — Step by Step
- Export the complete chat: WhatsApp → Conversation → Menu → "Export Chat" → Choose with or without media. Always export the entire conversation.
- Store the export file securely: Save the .txt or .zip file on a secure storage medium with a backup copy.
- Convert to PDF (GDPR-compliant): Use PrintChat to create a formatted PDF. PrintChat processes everything locally in your browser — nothing is uploaded to servers. Choose the legal transcript layout with Bates numbering.
- Document the chain of custody: Record the export date, device used, software used, and file storage location.
- Prepare a sworn statement: Confirm who performed the export, that messages are unaltered, and that the complete chat history is included.

WhatsApp Evidence in German Family Courts
Family courts (Familiengericht) are one of the most common settings for WhatsApp evidence in Germany:
- Custody disputes: Documenting missed pickups, communication refusal, parental alienation
- Domestic violence: Preserving threats, intimidation, and controlling behavior via WhatsApp
- Alimony disputes: Proving agreements about payments, income, or spending patterns
Always present complete chat histories — cherry-picked messages weaken your credibility. See our co-parent communication guide and divorce evidence guide.
Beweisverwertungsverbot — When Evidence Is Excluded
Germany's Beweisverwertungsverbot (evidence exclusion rule) prohibits the use of unlawfully obtained evidence. For WhatsApp, this applies when:
- Reading someone else's phone: Accessing WhatsApp on another person's device without consent is generally unlawful (§202a StGB — data espionage)
- Third-party forwarding: Messages forwarded by uninvolved third parties without sender consent
- Employer access: Employers accessing private WhatsApp on company devices requires strict conditions
Key principle: Messages sent directly to you can generally be used as evidence. Messages between other people that you obtained secretly are usually subject to exclusion.
GDPR (DSGVO) and WhatsApp Evidence Preservation
The GDPR directly affects how you may preserve WhatsApp evidence in Germany:
- Art. 6(1)(f): Processing is lawful when there's a legitimate interest — legal proceedings qualify
- Art. 17 (Right to erasure): Does NOT apply when data is needed for legal claims
- Data minimization: Courts expect only relevant portions, not all chat histories
Many WhatsApp-to-PDF converters upload your data to external servers — often outside the EU. This creates GDPR issues. PrintChat processes everything locally in your browser using WebAssembly. Your data never leaves your device. See our privacy risks comparison.
