What is commonly required when serving a legal document?

Providing proof of service to the court is an essential step in the process of serving a legal document. This proof, often referred to as an affidavit of service, acts as verification that the document was officially delivered to the intended recipient in accordance with legal requirements. It serves as evidence that the party has received the notice, which is crucial for the court to proceed with the case.

This requirement ensures that all parties have been duly notified, maintaining the fairness and integrity of the legal process. Without this proof, the court may not accept that proper notification has been completed, which could potentially delay or invalidate the proceedings. The other options do not satisfy the legal standards for proper service or are not appropriate methods of serving legal documents.
