What proof is needed to demonstrate service of process outside the United States?

To effectively demonstrate service of process outside the United States, a receipt signed by the addressee serves as strong proof. This signed receipt provides tangible evidence that the intended recipient has received the documents, thereby fulfilling the legal requirement for proper service. The signature of the addressee on the receipt verifies their acknowledgment of receiving the service, which is critical in legal proceedings as it substantiates that the defendant has been notified.

Other options may not provide the same level of assurance or formal recognition. For example, a sworn statement from the plaintiff lacks the objective verification that a signed receipt offers, while email confirmation does not typically constitute legal proof of service, as it can easily be disputed. Similarly, a video recording, while potentially useful as supplementary evidence, is often not required or sufficient on its own to satisfy the legal requirements of service of process outside the country. Thus, a receipt signed by the addressee is the most reliable and widely accepted form of proof in this context.
