When multiple cases share a common cause of action, common parties, or other common relationship, it is helpful to create a relationship between their cases in Needles. Once the related cases are created, use the Companion Cases feature to cross-reference the cases and simplify the case entry process by copying information from another case within the companion group. Companion cases can also be used to easily copy or move items from one to another as well as generate merge documents and forms for all cases in a group. The Companion Cases Tab shows all companion groups of which the current case is a member.
