Federal Labour Court Ruling: The End of Registered Mail with Delivery Confirmation?

When is a declaration addressed to an employee - such as a notice of termination - deemed received, and how can receipt be proven in a legally reliable manner? These questions are among the most sensitive practical issues in employment law. With its decision of May 7, 2026 (2 AZR 184/25), the German Federal Labour Court (BAG) dismissed the appeal against a judgment of the Hamburg Higher Labour Court (LAG Hamburg), thereby confirming the restrictive approach taken by the lower court. The signal is clear: in the view of the labour courts, Deutsche Post’s digital registered mail with delivery confirmation is no longer sufficient to establish a prima facie presumption of receipt.

Background: Developments in Case Law Since 2024

For many years, registered mail with delivery confirmation was a practical and commonly used method of service for employers. As a rule, employers could establish a prima facie presumption of receipt before the labour courts by presenting the posting receipt together with a copy of the delivery record. The recipient then had to rebut this presumption with substantiated evidence. According to the case law of the German Federal Court of Justice (BGH), this required compliance with the delivery procedure in place at the time: immediately before depositing the letter, the postal employee removed the so-called “peel-off label” from the item, attached it to the delivery record, and confirmed delivery with a signature and date.

As recently as October 2024, we reported on the BAG’s judgment of June 20, 2024 (2 AZR 213/23), in which the court generally upheld the presumption of receipt for registered mail with delivery confirmation, provided a proper delivery record could be produced. In a subsequent decision dated January 30, 2025 (2 AZR 68/24), the BAG clarified that merely presenting the posting receipt together with the online tracking information was insufficient. The decisive factor was that the employer had failed to download or request the delivery record from Deutsche Post within the 15-month retention period. The BAG emphasized that shipment tracking information alone does not indicate who delivered the item, to which address it was delivered, or at what time. However, the court expressly left open the question of whether a delivery record generated under Deutsche Post’s new digital procedure could, in principle, still establish a presumption of receipt.

What Was the Current Case About?

The case recently decided by the BAG concerned the validity of a dismissal on personal grounds. The employee had been frequently absent due to illness between 2020 and 2023. However, the dispute did not concern receipt of the dismissal itself, but rather whether the employee had actually received an invitation to attend a meeting regarding company integration management (BEM), which is generally required before a dismissal due to illness may be issued. The employee denied having received the invitation. The employer presented the posting receipt, shipment tracking information, and the delivery record, and named the postal worker as a witness. However, the witness was unable to recall the specific delivery. The Hamburg Higher Labour Court (judgment of July 14, 2025, case no. 4 SLa 26/24) held that the evidence provided for the registered mail with delivery confirmation was insufficient to establish a prima facie presumption of receipt of the BEM invitation. The court based its decision primarily on Deutsche Post’s revised delivery procedure. Under the former system, the postal employee removed the peel-off label immediately before depositing the letter and attached it to the delivery record. Today, the process is entirely digital: the postal worker scans the shipment number, signs on a digital device, and then deposits the letter in the mailbox. The date is automatically recorded by the system. The Hamburg Higher Labour Court identified several weaknesses in proving a typical course of events:

First, the digital delivery record does not document either the delivery address or the precise time of delivery. Second, unlike the previous peel-off-label procedure, the barcode can be scanned while the postal worker is still carrying multiple items, increasing the risk of misdelivery. Third, Deutsche Post’s procedures require delivery to be confirmed before the item is actually placed in the mailbox. Fourth, the delivery record does not distinguish between delivery into a mailbox and personal handover to the recipient.

By its decision of May 7, 2026 (2 AZR 184/25), the BAG dismissed the employer’s appeal against the Hamburg judgment. Although the written reasons for the decision have not yet been published, the dismissal is widely regarded by employment law practitioners as a strong indication that the BAG also considers the new digital registered-mail procedure insufficient to establish a prima facie presumption of receipt, even where a delivery record exists. This assessment remains subject to the court’s forthcoming written reasoning.

How Can Employers Play It Safe in Practice?

In light of these developments, employers should review and adjust their service procedures. The following alternatives provide a significantly higher degree of legal certainty:

Personal delivery with written acknowledgment of receipt remains one of the most reliable methods. Where a written declaration is handed over personally, it is generally deemed received immediately, provided it is given to the recipient for permanent possession. Delivery should be witnessed and documented.

Another tried and tested option is delivery by messenger with detailed documentation. The messenger may be a trusted employee or a professional courier service. It is important that the messenger is aware of the contents of the document, either obtains written confirmation of receipt upon personal delivery or deposits the letter in the mailbox, and documents the process in writing - ideally with photographs - recording the delivery, time, and contents.

Service by a court bailiff is also generally considered legally secure. The bailiff prepares an official record of service, which carries particularly strong evidentiary value. Another advantage is that if the recipient cannot be reached, the bailiff can effect substitute service by depositing the document, and service is nevertheless deemed completed. Employers should, however, allow sufficient time, as actual service depends on the bailiff’s schedule and workload. Especially where dismissal deadlines are tight, delays are possible. It is therefore advisable to specify the latest acceptable delivery date when instructing the bailiff.

Registered mail requiring the recipient’s signature is generally less advisable because the recipient may refuse acceptance or may not be present. In such cases, the item must be collected from the post office within seven working days. This can delay or even prevent effective service, creating significant risks for time-sensitive declarations.

In our view, registered mail with delivery confirmation should currently be used only as a supplementary measure alongside another legally secure method of service and should no longer be regarded as the primary means of proving receipt.

Service by email does not satisfy the statutory written-form requirement applicable to notices of termination. Irrespective of any proof-of-receipt issues, email is therefore not a valid method for serving a dismissal notice.

Outlook: Farewell to Registered Mail with Delivery Confirmation as the Standard Method?

Due to changes in Deutsche Post’s delivery procedures, the labour courts are imposing increasingly stringent requirements on proof of receipt and are moving away from the assumption that registered mail with delivery confirmation automatically establishes a prima facie presumption of receipt. If the BAG fully adopts the reasoning of the Hamburg Higher Labour Court in its written judgment, this would effectively mark the end of registered mail with delivery confirmation as a legally reliable means of proving service in employment law.

Employers are therefore well advised to switch now to proven alternatives such as personal delivery in the presence of a witness or messenger delivery with detailed documentation. Particularly for declarations requiring proof of receipt - such as dismissal notices, BEM invitations, or formal warnings - the proof of receipt should not be left to chance.
