A Firm ID is a unique 9-position ID, starting with an “F”, “H” or “L”, assigned during the annual attorney registration, and applicable only to private law firms, solo law practitioners, in-house counsels, legal service entities, non-profit organizations, and Administrative Office of the Courts legal units. When creating a new JACS account, please ensure that you complete the steps to associate (link) the Firm ID to the account, if you will be utilizing eCourts. Existing JACS accounts must also have the Firm ID associated (linked) to the account in order to file through eCourts. The eCourts system will not recognize the collateral account if the Firm ID has not been associated. If you need your Firm ID but do not know it, JACS provides a search capability either as a part of the process of creating a new JACS account, or through the Update Account screen for an existing JACS account. You can also call 609-421-6100 if you do not know your Firm ID.
