You will need to provide us with the case type (Civil, Criminal, Domestic, Probate, etc), the party names (John Smith, Jane Doe), and approximate year of filing.
Please note that a case may have been filed in a year or more prior to any orders signed. For example, if you are searching for a divorce case (Domestic) and it was finalized in 1968 it may have been filed in 1967 or earlier. Checking multiple years before and after may increase your success in finding the case information.
