According to federal rules for process service, who can serve federal papers?

The correct choice is that anyone 18 years or older can serve federal papers. This is based on federal rules governing the service of process, which typically require that the individual serving the papers be at least 18 years of age. This age requirement ensures that the server is legally considered an adult and capable of understanding the responsibility involved in serving legal documents.

While some roles, such as licensed attorneys or law enforcement officers, may have specific qualifications or privileges related to serving papers, the broader guideline allows any adult who meets the minimum age requirement to perform this duty. This approach enables flexibility and accessibility in the process of serving legal documents, ensuring that even individuals without specialized training can fulfill this important function.
