Abstract: The invention described is a computer based method for on-line legal docketing using an electronic customizable client rules subset. The method of the invention comprises of the following steps. Under control of a client system, a docket request message is sent to a host server system that is identified by a first uniform resource locator (URL), the host server system having a client case listing database containing legal case information from at least two client systems. The docket request message further comprises pattern data and a pattern data date. Under control of the host server system, it receives the docket request message, identifies the client system using a client system identifier, identifies the customizable client rules subset in a rule module database associated with the identified client system, and using the pattern data contained in the docket request message selects at least one associated action prompt from the customizable client rules subset.
