Terminations, warnings, deadlines: service methods for nonprofits still accepted under Federal Labour Court case law
In our article dated April 27, 2026, we explained the legal position in Germany regarding registered mail delivered by deposit into the recipient’s mailbox (Einwurf-Einschreiben). Such delivery can only serve as prima facie evidence of receipt of an important document if both the mailing receipt and the delivery confirmation are submitted.
This assessment must now be revised in light of the most recent judgment of the German Federal Labor Court (BAG). In its decision, the BAG held that even the delivery confirmation issued by Deutsche Post no longer constitutes sufficient proof of a typical and reliable delivery process. As a result, the delivery confirmation is no longer sufficient to prove that a document has actually been received by the recipient.
Why registered mail no longer proves delivery
The court primarily justified its legal view by stating that today’s digital delivery processes are not sufficiently transparent or verifiable to reliably conclude that a document has actually reached the recipient.
Under the former procedure, the postal worker would remove the so-called peel-off label directly before depositing the item, affix it to the delivery receipt, and confirm delivery with a signature and date. This created a clear and traceable sequence of events that supported a presumption of receipt. Today, however, the process works differently. The postal worker simply scans the shipment code, confirms delivery via a digital input field, and the date is automatically recorded in the system.
The court identified significant shortcomings in this system. In particular, the digital confirmation does not document the recipient’s address or the exact time of delivery. Scanning may also occur while the postal worker is still holding other items. In some cases, confirmation is recorded even before the item is actually deposited. In addition, the system does not distinguish between deposit into a mailbox and personal handover. As a result, it is no longer possible to derive a typical delivery process from which receipt can reliably be inferred.
Nonprofits, foundations, and gGmbHs: Time to update delivery and service practices
For German nonprofit organizations, this development is particularly relevant. Many associations, foundations, and nonprofit limited liability companies (gGmbHs) operate with lean administrative structures and limited resources. As a result, delivery and service processes are often organized in a pragmatic way and remain largely unchanged for many years.

For precisely this reason, registered mail delivered by deposit into the mailbox has often been the preferred method in practice, as it was considered cost-effective, easy to manage, and, until now, legally sufficiently reliable. In addition, many smaller organizations do not have in-house legal departments and therefore rely more heavily on standardized and legally secure processes.
In light of the current case law of the Federal Labor Court, this practice now requires urgent adjustment, as delivery of documents requiring proof of receipt via registered mail with mailbox deposit can no longer be recommended as the sole method of delivery.
Which documents should no longer be sent by registered mail with mailbox deposit?
The implications of the decision generally affect all legally relevant declarations that require receipt by the other party in order to become effective. This includes in particular:
- terminations
- written warnings
- modification notices
- notices of fixed-term arrangements
- revocations
- settlement offers
- notices setting deadlines
In the context of associations and foundations, this may also apply to invitations, exclusions, or resolutions of governing bodies, insofar as their legal validity depends on proper receipt. The practical relevance varies depending on the specific case.
For example, if the receipt of a termination cannot be proven, this may lead to significant employment law-related or financial consequences, even if the decision itself is substantively valid. This is particularly critical in cases involving deadlines, employment disputes, or sensitive HR measures.
For less sensitive or non-time-critical communications, the remaining risk may be acceptable in individual cases. However, for legally significant or deadline-dependent declarations, greater emphasis should in future be placed on reliable proof of delivery.
Legal consequences for registered mail with mailbox deposit
This means that registered mail delivered by deposit into the recipient’s mailbox is losing a significant part of its former evidentiary value in practice. Although the full reasoning of the court has not yet been published in its entirety, the direction of the case law is already clearly apparent: organizations in Germany should no longer rely solely on this method for legally sensitive correspondence.
Anyone seeking to prove receipt exclusively through registered mail with mailbox deposit – even when presenting the delivery confirmation – and facing a denial by the recipient will bear the full burden of proof. If receipt of a legally relevant declaration cannot be proven, the declaration is deemed not to have been received and therefore produces no legal effect. In such cases, a termination would be invalid, and a deadline would not be met.
As a standalone basis for proving receipt, registered mail with mailbox deposit is therefore no longer suitable.
Recommended delivery methods for Nonprofits in Germany
The current case law of the Federal Labor Court makes it clear that registered mail with mailbox deposit has largely lost its former status as a reliable standard for important delivery of documents. The delivery of key declarations should therefore not be left to chance.
For legally sensitive correspondence, nonprofit organizations should instead rely on delivery methods that provide significantly more robust proof of delivery. Preferable options include:
- personal handover in the presence of a witness against a written acknowledgment of receipt
- documented messenger delivery, or
- in particularly sensitive cases, service by a court officer
Registered mail with mailbox deposit may at best still be used as a supplementary measure but it is no longer suitable as the sole method of proving receipt.
