Who has to prove receipt?
A declaration to an absent person takes effect only on receipt (§ 130 BGB). Receipt must be proven by whoever relies on it — you as the sender. A plain letter barely helps: per case law, even a posting receipt doesn't prove arrival.
Evidence that counts
- Einwurfeinschreiben with delivery record: according to the Federal Court of Justice (judgment of 27 Sept 2016, II ZR 299/15), a properly documented drop-off indicates receipt — the recipient must then present reasons against it.
- Handover registered mail / return receipt: the signature proves handover.
- Messenger with witness who knows the content and saw the drop-off.
- Bailiff service under § 132 BGB — the safest route.
- a written confirmation from the recipient.
What to do now
- Secure evidence: letter copy, receipt, tracking screenshot (data is only available for a limited time).
- Resend immediately with delivery proof. If the deadline has passed, a cancellation usually takes effect at the next possible date.
- Object in writing: state when and how you sent it, with copies of the evidence.
- If lost: file a tracing request with Deutsche Post — see letter not arrived.
Prevent it next time
For anything with a deadline: send early and with proof. With the letter editor you send online with a dispatch confirmation — no trip to the post office.
