What is required when a summons is served by someone other than a sheriff?

When a summons is served by someone other than a sheriff, it is essential to file a return accompanied by an affidavit that establishes proof of service. This requirement ensures that there is a legal record documenting that the summons has been properly served to the intended party. The affidavit serves as a declaration from the process server, providing details such as when, where, and how the service was executed. This documentation is critical in verifying compliance with legal procedures and can be referenced in future court proceedings if disputes arise regarding the service of the summons.

The other options suggest various administrative tasks or notifications that do not fulfill the legal obligation to confirm and document the service effectively. The affidavit provides an official and detailed account that is necessary for the court's records, making it the correct answer in this scenario.
