The fact remains: Notice of termination can only be legally valid if delivered by a messenger.

The dynamics of the global job market present significant challenges for both companies and foreign professionals . In the world of global mobility, international recruiting, and corporate immigration, the legally compliant exchange of documents is a crucial element for the success of all parties involved . Particularly when employment relationships are terminated, a single formal error or delayed delivery can have far-reaching consequences – both for the employer, who is suddenly confronted with unforeseen claims for continued wage payments, and for the foreign professional , whose residency status in Germany is often directly linked to the existence of a valid employment contract. A recent ruling by the Federal Labor Court now provides definitive clarity on an issue that has concerned HR departments and expats for years. It demonstrates once again that supposedly modern methods of service of process do not hold up in court when push comes to shove .

The delivery of declarations of intent, particularly notices of termination pursuant to Section 623 of the German Civil Code (BGB) , which mandates written form, regularly causes considerable difficulties in practice. Under German civil law, a declaration of intent made to an absent party is only deemed received, according to Section 130 Paragraph 1 BGB, when it has entered the recipient's sphere of control and, under normal circumstances, the recipient can be expected to take notice of it. Many employers feel secure when using postal services and readily opt for registered mail with delivery confirmation. For a long time, this method seemed the ideal compromise, as the postman delivers the letter directly into the mailbox, and delivery is documented. The advantage over traditional registered mail with return receipt is obvious: If the postman does not find the employee at home, only a notification slip is left with the return receipt. If the employee then fails to collect the letter from the post office – whether due to ignorance, vacation , or deliberate intent – the letter is not considered delivered . In contrast, with registered mail with delivery confirmation, delivery occurs regardless of the recipient's presence. Nevertheless, this method carries significant legal risks that are often underestimated by many HR departments.

Until recently, the evidentiary value of proof of delivery for registered mail with return receipt in unfair dismissal proceedings was highly controversial in legal scholarship and practice. Now, the Federal Labor Court (BAG) has decided this crucial question with far-reaching consequences for corporate immigration and HR management. In its recent ruling ( Case No.: 2 AZR 184/25 ), the BAG dismissed the appeal against a judgment of the Hamburg Regional Labor Court (Case No.: 4 SLa 26/24). The ruling leaves no room for doubt: According to the BAG, the submission of proof of delivery for registered mail with return receipt cannot establish prima facie evidence of actual receipt of the dismissal notice. The Hamburg Regional Labor Court had rightly argued in the lower court that the registered mail with return receipt procedure is simply too prone to error. Furthermore, the digitized delivery receipt, which employers do not automatically receive but must request from Deutsche Post within strict deadlines at their own expense, lacks essential information such as the recipient's exact address and the precise time of delivery. If the employee disputes receipt of the letter in court, the employer, despite sending it by registered mail, is left without the necessary full proof.

For internationally active companies, young professionals, and expats, this case law has immense significance that extends far beyond pure labor law . If a dismissal is invalid due to a lack of verifiable delivery or if delivery is delayed, the three-week period for filing a claim under Section 4 of the German Protection Against Unfair Dismissal Act (KSchG) may not even begin. For the employer, this represents an extreme financial risk. From the perspective of highly qualified foreign professionals and academics, their entire life plans in Germany often hinge on the validity and precise timing of a dismissal. According to the regulations of the German Residence Act (AufenthG), particularly for holders of an EU Blue Card under Section 18g AufenthG or a residence permit for skilled workers under Sections 18a or 18b AufenthG, residency is tied to the specific employment contract . If expats or diplomats lose their jobs, they are obligated to inform the immigration authorities immediately. An unclear situation regarding the exact termination date not only complicates the search for a new employer in the context of international recruiting, but can also lead to unintentional violations of immigration law. Legal certainty regarding the receipt of the termination notice thus protects the employer's compliance and, at the same time, the immigration status of the foreign employee.

Given the Federal Labor Court's (BAG) clear rejection of registered mail with return receipt, employers and legal departments have only one truly legally secure way to deliver important documents. We strongly recommend that notices of termination and other time-sensitive declarations be delivered exclusively by courier. Ideally, this should be done by a dedicated employee or a specialized courier service. The courier personally delivers the letter to the employee's mailbox or hands it directly to them. The crucial step for admissibility in court is complete documentation. A detailed delivery receipt must be completed in original form and signed by the courier. This receipt must include the exact date, the precise time, the correct address, and confirmation that the specific notice of termination was delivered to the mailbox. Only by following this procedure can the employer provide full proof of receipt in accordance with Section 286 of the German Code of Civil Procedure (ZPO) in the event of a dispute. For HR departments in the field of corporate immigration, this method should be firmly anchored in the compliance guidelines in order to consistently exclude existential legal risks in international human resource management.

The recent ruling by the Federal Labor Court underscores that German labor law leaves no room for compromise in formal processes. Registered mail with delivery confirmation has definitively lost its perceived status as a secure delivery alternative, as it provides no prima facie evidence of receipt in a dispute. For employers in the fields of global mobility and international recruiting, this means that personal delivery by a courier, along with a detailed record, is indispensable when serving notices of termination. This is the only way to avoid lengthy and costly legal proceedings . This decision also provides clarity for highly qualified foreign professionals: it protects them from opaque deemed service provisions and ensures a reliable basis for assessing their residency status in Germany. As an experienced law firm, we support companies and expats in implementing these strict legal requirements in a legally compliant manner and effectively preventing compliance violations.
