The system automatically saves your data as you go from screen to screen using the NEXT button.
As you go through the filing screens (Case Info, Parties, Documents, Payments etc) always use the NEXT button to continue. Using the NEXT button will save the data you just typed and go to the next screen.
When you are attaching documents, clicking the SAVE button at the bottom of the screen will upload the attachment file you have specified and then you will be prompted again to "Add Document" (you can attach more than one document to one filing session for one case) or click NEXT to continue.
HOWEVER . . .
You must not use your browser's "back/next" arrow buttons (in Internet Explorer, the arrow buttons in the upper left corner of the screen). If you use your browsers buttons, you will lose all your data for that filing and you will need to start again.
The system can time out! The time out is set for 2 hours. If you are in the middle of a filing and you leave your PC for more than 2 hours you will lose all of the data you entered for that filing.
The system does not currently allow you to save "work in progress". For example, you cannot add some attachments into a filing, save, and then sign on later and add more documents to the same filing. You should plan to have all your attachments for a case ready (in .pdf format) before starting a filing.
