Espinoza v. Hewlett-Packard Company, C.A. 6000-VCP (March 17, 2011)

Occasionally a complaint or other document is filed under seal in the Court of Chancery.  This decision explains how to do that and the limits on confidentiality you can expect.  As the courts are public institutions with a need to have their proceedings out in the open, the short answer is that do not expect much to remain confidential no matter how embarrassing it may be to you or your client.
