Performing due diligence is an instrumental aspect of process service. The law demands that we show that every reasonable measure has been taken to make contact with, and provide documents to, the servee. As a process server, a significant portion of proving due diligence falls on you. Let's be honest - most people aren't home at noon; so varied and meaningful attempts at service go a long way! Here are some examples of how to show due diligence:
Along with meeting the expectations of due diligence, ABC also requires that attempts be made every 48 hours on each service assigned to a process server. If you have selected an area to be assigned in you are agreeing to meet the above requirements of diligence as well to make this frequency of attempts on all the work received in that area.
