What is a common challenge faced by process servers?

Encountering individuals who refuse to accept documents is indeed a common challenge faced by process servers. The nature of a process server's job is to deliver legal papers to individuals involved in legal proceedings, such as summonses or complaints. Often, the individuals being served may be reluctant to accept these documents due to various reasons, including fear, anger, or simply wanting to avoid the legal process. This can make the process of serving papers more complicated, as servers must employ skill and persistence to ensure that the documents are delivered properly. In many cases, process servers might have to use different strategies, such as serving at different times, checking at various locations, or even utilizing the assistance of law enforcement when necessary, to successfully complete their task.

The other options, while they may touch on aspects of process serving, do not represent as significant or direct a challenge as the issue of documents being refused. Legal training, working in person, and technology resources may vary in importance but are not universally encountered obstacles in the same manner.
