A long article in the ACC Docket, Vol. 27, May 2009 at 47, mentions (at 50) that matter management systems can absorb data electronically from service-of-process (SOP) agents. Registered agents, as they are also called, enter information about complaints, subpoenas and other records served on them as the official agents for your company. Sometimes they scan the documents and can provide them to you.
You might want your matter management system to be able to incorporate that initial information and thereby save your staff the trouble of re-entering it. Other functions let the SOP data be routed to a responsible person and keep track of information such as dates of receipt and response dates (See my post of Oct. 1, 2006: CT Corporation integrates data with matter management system.).
