A Notice of Docket Activity (NDA) is a notice sent via email that is generated when a docket transaction requires that notice be sent to attorneys, case participants, and/or court personnel. NDAs can be generated when a party or attorney files a document with the clerk's office or when the court enters an order or takes other public action in a case. If you are a CM/ECF participant, your receipt of the NDA is service of that document or order, and registration in the CM/ECF system constitutes consent to receive service through the NDA. Generally, an NDA contains a hyperlink back to the court's docket sheet and the document in question. When parties receive an NDA they can click on the document and obtain a "free look" at the document. Because there is only one free look, parties should be sure to save the document upon that initial review. In the district court and bankruptcy court systems the NDA is called the Notice of Electronic Filing (NEF).
